Cyber Security Architecture

In many of my discussion with small to medium business owner on the subject of Cyber Security and how it may impact them, one of the things that does stand out, amongst quite a few, is the lack of understanding about security architecture. So, I thought it was worth discussing it further.

What is security architecture? Well, in a nutshell it’s the technical elements of security that are used to mitigate cyber risks. Many of you may have read or heard of me talking about the differences between IT Security ie, the technical elements, and Cyber Security ie, the risk managed elements, a more holistic approach if you like. And of course, the two remain separate whilst maintaining a symbiotic relationship in that one begets the other, or it should. Security architecture, in order to be fully effective, has to be based on risk management ie, if you haven’t identified the risks, how can be sure that whatever technology you’ve been persuaded to buy, is necessary and effective?

All SMEs will have things like a firewall and anti-virus, possibly going a step further and having some form of end point protection against most malware attacks. But how did they arrive at the products they have purchased and taken into use. Well generally that is based solely on the recommendation of whatever IT support company they’ve bought it from. Usually, the local IT company that they use to supply their hardware and software and who often provide technical support as well.

I’m not against building a relationship with a local IT provider, in fact it’s a very good idea, but all SMEs have to realise that those companies are what is known as Value Added Resellers or VARs. What that means is that they have a relationship with hardware and software vendors and that their staff are trained in the installation, configuration and sometimes maintenance, of those vendors hardware and software. Is that a problem? That depends very much on how the requirement for a solution was arrived at. Was it based on identifying the risk through some form of risk assessment process, or was it arrived at because that’s the products they sell and are comfortable with? All too often it’s the latter.

I’ve also talked elsewhere about the other non-technical controls that might be required, such as policies and process, another subject but one which is vitally important and can often be better placed to protect a company than expensive tech.

How many SME owners have had the reasoning behind the purchase of technical solutions explained to them? And to be fair to the VAR, how many SME owners have asked for it to be explained to them? It is typical, when I visit SMEs, to find that they have what is known as a flat network. That means that they have one gateway into the network, introducing a single point of failure, and no segmentation within the network. Lack of segmentation means that once an intruder is in, and often the gateway firewall is a dual firewall/router entry level device, not the best, then there are no other controls to stop the intruder from attacking end points, such as for instance, your finance department/person, or perhaps just taking whatever data they want in a stealth attack, so that you don’t even know it’s been compromised.

Of course, these days that is often exacerbated by the increasingly popular remote working. I know not every company has embraced this, but many have and have not through the security implications.

Segmentation, remote access and remote security solutions need not be overly expensive to implement and may save a lot of money in the long run. But the main point is that unless you have carried out a risk assessment, then you don’t actually know whether you need a particular solution or not. Neither do you know whether your firewall and/or router is up to scratch, whether your anti-malware system is doing what you think it’s doing, whether your policies and processes are adequate for the task and whether your staff understand the issues and dangers.

None of these things need be complicated and difficult but they are essential to adequately protect you against and increasingly sophisticated and ever evolving cybercriminal community.

Do You Have a Handle on Your Cyber Maturity Stance?

Over the years I’ve had some very interesting conversations with several people from multiple different verticals, but all fitting comfortably within the SME bracket, around Cyber Security. The conversations often tend to take a very familiar turn. The cry of, ‘I’m covered, my IT support company has put in a firewall and some anti-virus. They tell me all is good’. Slightly depressing but not terribly surprising.

Even though cyber security and data loss prevention have leapt to the top of many people’s agenda in recent years, it is still common amongst many SMEs to believe that it is an IT problem, a technical problem rather than a business issue, even when recognising that the risk of a cyber intrusion or a data breach, impacts the business, the bottom line. So, is it an IT issue or a business issue?

The National Cyber Security Centre (NCSC), a department of GCHQ Cheltenham, estimates that if you are an SME then you have around a 1 in 2 chance of experiencing a cyber security incident of some sort. For the small business this could result in costs they could well do without, and I know of one business that has been hit for around £30000, which I am sure you will agree, can be extremely damaging to the bottom line of businesses operating under tight margins. And of course, it’s not just financial penalties but the reputational damage should your customers data and assets be affected as well.

As we travel around and visits clients or potential clients, it is common to find that they have the view that adequate security is provided by technology. They rely on their IT provider to provide the guidance they need which tends to involve firewalls, anti-malware software and perhaps a backup regime. All well and dandy. A quote from Bruce Schneier, Fellow at the Berkman Center for Internet & Society at Harvard Law School, goes like this:

‘If you think technology can solve your security problems, then you don’t understand the problems and you don’t understand the technology’.

It is a common misconception is that IT Security is the same as Cyber Security. That surprises a lot of people, so let’s explore it a bit. There is clearly a close symbiotic relationship between the two disciplines. I would argue, and I know this might meet with some disagreement, that IT security refers to traditional IT security methods which are technology based. Such as firewalls, anti-malware, end point protection etc. Whilst Cyber security is based very much on risk management which combines controls which are both non-technical and technical, following the principles of People, Process and Technology.

Within the SME world this tends to mean that there is a heavy reliance on third party IT providers. Is that a good thing? After all that’s in their area of expertise and responsibility, isn’t it? And here comes the controversial bit. Third party IT providers, particularly in the SME space, are pretty much exclusively value added resellers or VARs, i.e., companies that sell other company’s products. Now I’ve no problem with that per se, but it comes with issues. Notable amongst them is that these companies will have skill sets that are very much limited to the products they sell. Ie they are proficient in the installation and configuration of those products and their clients are offered those products whether they are best in class, or more importantly, whether they are the most appropriate for the task. Before I get a social media pile on, I know that some of the bigger VARs do sell multiple vendors products, but they are in a minority.

Before we go any further, let’s briefly explore some issues that are common amongst SMEs. Some common myths first:

Small to medium size businesses are not worth attacking.
Cyber Security is an IT Issue.
Technology will keep me safe.
My policies and procedures are up to the job.
My staff are young and have been brought up with IT. They know the score.

Now let’s look at some of the more common issues that we see often amongst SMEs:

Lack of awareness around the current real-world cybersecurity risks
False sense of security, with a heavy reliance and dependence on an external IT third-party provider
Lack of cybersecurity knowledge, and understanding
Poor cybersecurity maturity and posture within their businesses
Lack of staff training (at all levels) – just like Health & Safety, cybersecurity is everyone’s responsibility.

Here at H2 we offer a cyber maturity assessment that is designed specifically at SMEs. It is a comprehensive evaluation of an organisation’s cybersecurity capabilities and readiness to effectively mitigate and respond to cyber threats. It involves a detailed analysis of the organisation’s cybersecurity policies, procedures, technologies, and practices. The assessment aims to identify potential vulnerabilities, weaknesses, and areas for improvement in the organisation’s cybersecurity posture.

During the assessment, we typically examine various aspects, such as:

Governance and Management: Reviewing the organisation’s cybersecurity policies, risk management frameworks, and leadership’s commitment to cybersecurity.

Security Awareness and Training: Evaluating the level of cybersecurity awareness among employees and the effectiveness of training programs.

Technical Controls: Assessing the implementation and effectiveness of security technologies, such as firewalls, intrusion detection systems, antivirus software, and encryption mechanisms.

Incident Response and Recovery: Analysing the organisation’s incident response plan, including procedures for detecting, reporting, and responding to cyber incidents.

Security Risk Management: Evaluating how the organisation identifies, assesses, and manages cybersecurity risks.

Third-Party Risk Management: Assessing the organisation’s approach to managing cybersecurity risks associated with third-party vendors and partners.

Compliance and Regulations: Verifying the organisation’s compliance with relevant cybersecurity regulations and industry standards.

The results of the Cyber Maturity Assessment provide valuable insights to the organisation, enabling them to enhance their cybersecurity defences and establish a more robust and resilient security posture. It helps organisations prioritise their investments in cybersecurity, address vulnerabilities, and strengthens their overall cyber resilience and provides a road map to reach a standard agreed with the management, taking full account of that managements risk appetite.

SPOOFING

I’ve mentioned spoofing quite a bit in various posts and blogs, but what exactly is it? Spoofing, as it pertains to cybersecurity, is when someone or something pretends to be something else, attempting to gain our confidence to get access to our systems, steal data, steal money, or spread malware. These attacks come in several forms, including:

Email spoofing
Website and/or URL spoofing
Caller ID spoofing
Text message spoofing
GPS spoofing
Man-in-the-middle attacks
Extension spoofing
IP spoofing
Facial spoofing

Cyber criminals aren’t all that original and spoofing is another con to fool us into taking some form of action that the criminal wants us to take; in other words, it’s a more technical variation on a con artists skill set. Very often, merely invoking the name of a big, trusted organisation is enough to get us to give up information or take some kind of action. For example, a spoofed email might inquire about purchases you never made. Concerned about your account, you might click the included link.

From that malicious link, scammers will send you to a web page with a malware download or a faked login page, complete with a familiar logo and spoofed link to a web page, for the purpose of harvesting your username and password.

There are many more ways a spoofing attack can play out. In all of them, fraudsters rely on victims falling for the fake. If you never doubt the legitimacy of a website and never suspect an email of being faked, then you could become a victim of a spoofing attack at some point.

Let’s look at some types of spoofing.

Email spoofing is the act of sending emails with false sender addresses, usually as part of a phishing attack designed to steal your information, infect your computer with malware or just ask for money. An example of this is the fabled CEO attack whereby a spoofed email is sent to someone in your accounts payable department attaching an invoice from a fake supplier and purporting to come from the CEO or other senior manager, with the instruction to pay the invoice now, without delay, and sounding like the senior manager is angry about something. Of course, this is quite easy to defend against by having a rule in place that if a suspect email is received, the alleged sender should be contacted for verification. Be aware though, if you simply reply to the email, it will go back to the scammer, you must open a fresh email or make a call.

Phishing emails will typically include a combination of deceptive features:

False sender address designed to look like it’s from someone you know and trust, maybe a friend, coworker, family member, or company you do business with.
In the case of a company or organisation, the email may include familiar branding, e.g. logo, colours, font, call to action button, etc.
Spear phishing attacks target an individual or small group within a company and will include personalised language and address the recipient by name.
Typos. Email scammers can be lazy and often don’t spend much time proofreading their own work. Email spoofs often have typos, or they look like someone translated the text through Google Translate.

Website spoofing is all about making a malicious website look like a legitimate one. The spoofed site will look like the login page for a website you frequent, down to the branding, user interface, and even a spoofed domain name that looks the same at first glance. Cybercriminals use spoofed websites to capture your username and password (aka login spoofing) or drop malware onto your computer.

Caller ID spoofing happens when scammers fool your caller ID by making the call appear to be coming from somewhere it isn’t. Scammers have learned that you’re more likely to answer the phone if the caller ID shows an area code the same or near your own.

Text message spoofing or SMS spoofing is sending a text message with someone else’s phone number or sender ID. If you’ve ever sent a text message from your laptop, you’ve spoofed your own phone number to send the text, because the text did not actually originate from your phone.

Man-in-the-Middle (MitM) attacks can happen when you use free Wi-Fi at your local coffee shop. Have you considered what would happen if a cybercriminal hacked the Wi-Fi or created another fraudulent Wi-Fi network in the same location?

Extension spoofing occurs when cybercriminals need to disguise executable malware files. One common extension spoofing trick criminals like to use is to name the file something along the lines of “filename.txt.exe.” The criminals know file extensions are hidden by default in Windows so to the average Windows user this executable file will appear as “filename.txt.”

IP spoofing is used when someone wants to hide or disguise the location from which they’re sending or requesting data online.

Facial spoofing might be the most personal, because of the implications it carries for the future of technology and our personal lives. As it stands, facial ID technology is limited. We use our faces to unlock our mobile devices and laptops, and not much else. This is likely to spread, and the use of AI makes facial spoofing more likely. Imagine if we advance to using facial recognition to make online payments – scary stuff.

There’s a lot more to this subject, for instance, how do you spot it? How do you protect yourself against it? The best form of defence is simply cyber awareness training, something you’re probably getting fed up hearing from me. But it’s simply a fact that your staff can be your first line of defence, or your biggest threat.

Malwarebytes have published a more detailed article on this subject but even that needs some understanding and explanation.

Scams v Hacks

We hear a lot about the consequences of cyber-attacks and data breaches but not a lot about the specific threats against SMEs, rather than the generic threats against all businesses. In general businesses are more likely to be targeted by scammers (social engineering attacks) than by purely technical attacks. But why? Attacks against individual SMEs are not going to bring in a lot of profit for the criminal, so they often go after multiple targets all at once. How they do that is to craft an attack which can be automated and directed at many SMEs all at once. The easiest way to do that is via a social engineering attack. Let’s take a look at what we mean by that.

Scams and social engineering attacks rely heavily on human error. Not only do SMEs have weaker defences than their corporate cousins, but they spend little, if anything, on cyber awareness training. The attack that brought down Knights of Old, reducing a once thriving business to bankruptcy in a frighteningly short time, was the result of a weak password being cracked. That suggests that OK, a stronger password protocol and the use of MFA would have been of great benefit but so would educating the users about social engineering and how they can protect the company and their jobs.

Typically, we see:

Phishing emails that trick employees into giving credentials or downloading malware.
Business email compromise (BEC) — attackers impersonate executives to request bank transfers or the immediate payment of an invoice.
Fake invoices or supplier fraud.

It’s done this way simply because it’s easier and cheaper to execute than a technical attack. It’s scalable with scammers sending thousands of phishing emails, and it often bypasses technical defences by exploiting people directly.

In addition to the traditional attacks, we are now facing AI generated attacks, enabling criminals to design scams that are even more scalable and to be produced more quickly. Some examples include:

Deepfake CEO Fraud (AI-Generated Voice or Video)

A finance employee receives a video call from someone who appears to be the CEO instructing them to urgently transfer funds to a supplier. The video and voice are AI-generated deepfakes using real footage and voice samples taken from public online sources. This has happened in the UK causing a UK based firm to lose over £20m in early 2025. Obviously not an SME but the attack was not difficult to generate.

Another AI attack was an upscale of the Business Email Compromise:

Criminals use AI to monitor and mimic email communication styles. They craft perfectly worded emails from a company executive asking the accounting team to update supplier bank details or pay fake invoices. What is new in 2025 is that AI now personalises these scams based on internal speech patterns and tone scraped from Slack or Teams (when credentials are compromised and that list is not exhaustive – other online messaging systems are available).

One scam that we are now seeing more of is the fake job applicant scam targeting HR departments and IT onboarding teams. Scammers apply for remote jobs using fake CVs and AI-generated video interviews. Once hired, they gain access to internal systems and exfiltrate data or install malware. They’re playing the long game here, but it can really pay off.

There are lots of examples and I’ll just put in a couple more:

How many of you use Software as a Service (SaaS) and pay a subscription? In this case a fake renewal notice is sent for services like Microsoft 365, Zoom, or Slack. The email contains a link to a spoofed portal, which steals company admin credentials when they try to “log in.” A new twist in 2025 is that the phishing emails are personalised with real invoice numbers and recent usage data scraped from prior breaches.

Most of you are probably on LinkedIn, even if you are not particularly active on there. We are now seeing more of the LinkedIn Clone Attack. What happens here is that the scammers clone the LinkedIn profile of a known business leader and use it to reach out to employees or partners, proposing urgent collaborations or investment opportunities that include malicious links. In a more advanced tactic, they use AI-generated responses in real-time chats that make these accounts seem very real.

So, in conclusion, whilst we cannot rule out the more technical attack on an SME, we can say that the most likely attack will come via some sort of scam, often nowadays using AI. The defences need to be in depth and will include some technical defences but often the best defence against social engineering is cyber awareness training and this is generally ignored by SMEs.

A Guide to Cyber Security for SMEs

There’s a continual stream of blogs and posts about cyber security and the sometimes catastrophic effects of getting it wrong, but there is very little that tells SMEs what they should be doing, and it’s generally left to local IT management companies and VARs (Value Added Resellers – i.e. those who sell various products and add value by configuring and managing them). I’m not knocking those companies; they have a very valid business model. But what they aren’t are cyber security professionals and generally their security expertise is focused on the products that they sell. For instance, they will have good skills in installing and configuring security products such as anti-virus and firewalls but there is generally no knowledge of cyber risk management and assessment, thereby ensuring that you have the right defences in the right place, providing the best value for your limited spend, and ignoring the non-technical solutions that are often a better bet than a piece of technology.

SMEs generally have very little budget to allocate to this and that means that what budget they have needs to be effectively targeted at what is important. They need to be aiming for a situation whereby when a potential attacker targets them, they appear to be a more difficult nut to crack than other organisations in their space and their size. Attackers want things to be easy, not difficult, and they will often move on if things get difficult. A criminal is in the game of getting easy money.

Let’s take a look at what cyber security is all about, and more importantly, why you need it? Let’s tackle the first question – what is cyber security? One definition is as follows:

Cybersecurity is the practice of protecting computer systems, networks, software, and data from digital attacks, unauthorised access, damage, or theft. It involves a range of technologies, processes, and practices designed to:

Prevent cyberattacks
Detect breaches or suspicious activity
Respond to security incidents
Recover from damage or loss caused by attacks

The problem is of course that each bullet point there covers a multitude of issues that need to be addressed. The question is understanding what those issues are, how they affect you and what is the priority i.e. what are the most important things that you need to protect, and what comes next, all managed within whatever budget you can allocate to it. It’s not easy and you might feel that you don’t need to do everything but that you need to cover off the most important issues. That means of course that you need to know what those issues are.

The first thing you need to do is to identify your cyber assets. Assets are not confined to hardware and software, far from it. A cybersecurity asset is anything of value that requires protection in a digital context. Identifying and classifying these assets is a foundational step in building a strong cybersecurity posture. Assets will change from company to company, depending upon how you’re organised and what business you are in, but generally:

Hardware Assets

Servers, routers, laptops, mobile devices, firewalls
Why it matters: Physical devices are entry points for attackers and must be secured.

Software Assets

Operating systems, applications, databases etc
Why it matters: Vulnerabilities in software can be exploited to gain unauthorised access.

Data Assets

Customer records, financial data, intellectual property, source code
Why it matters: Data breaches can lead to regulatory fines, reputational damage, and financial loss.

Network Assets

VPNs, switches, IP addresses, subnets
Why it matters: Networks facilitate communication and, if not protected, can be avenues for lateral movement by attackers.

People Assets

Employees, contractors, system administrators
Why it matters: Human error is a leading cause of breaches, so training and access control are crucial.

Cloud and Virtual Assets

Virtual machines, containers, cloud storage (e.g., AWS S3, Azure Blob Storage)
Why it matters: Cloud environments introduce new attack surfaces that must be monitored and managed.

An example could be a customer database, maybe on the cloud or via an app, or even an onsite server. You class this as high value because it contains personally identifiable information (PII) and of course all your interactions with those customers and the value they have to you. Lose that and you might be out of business. You decide to encrypt it and use multi factor authentication and have daily backups, not kept online.

Identifying the assets is the first step in defining what protections you need. You then have to categorise those assets and decide how important they are to the business before you can decide what levels of protection they need.

Having categorised your assets, you then need to assign a risk score to them. Now, this can be done formally via a formal risk assessment, but I accept that many SMEs can’t afford to have that done, and, given the size of the company and the amount/types of information held, it might be relatively easy, when compared to a corporate body, to assign a risk score to each asset.

The next step then is to apply a risk score to the assets in accordance with how you have assessed them, this in turn informs you of the importance of each asset and how you will need to protect them. In other words, you are now targeting your spend to where you know it will be most effective.

We then need to identify the vulnerabilities and the threats and that is where most organisations require help.

Here at H2 we use our considerable experience in doing this for corporate level organisations, and translating that into doable chunks for SMEs, carving up what is needed into priorities and working with clients to decide what those priorities are. We do this keeping in mind the principle of People, Process and then Technology, keeping in mind that many protections, or controls as we term them, are actually not technical but are procedural, based on sound policy and process, and therefore costing very little.

We take a phased approach:

The first phase works with the client to decide where they are now, on a scale which we take from the Carnegie Melon cyber maturity model. Most SMEs come out at around 1 to 2 on the scale and aim to get to 3 to 3.5. The scale goes up to 5 but, as you can see from the phased approach above, this tends to be not necessary for an SME and is often too expensive anyway.

Once we know our starting point, we identify quick wins to tighten up security. As a rule, that will include things like cyber awareness training for staff, ensuring that all access is controlled using MFA of some sort and making sure that Admin rights are strictly controlled. Depending on the company and what it does, it might mean instituting some form of identity management.

As part of the Quick win phase, we also look at policies and processes. Is there a process for allocating and removing rights? Is there a policy and process about on and off boarding staff etc. Other policies we might need to look at include:

Top-level policy issued by the board
Starters and Leavers Policy
Access Control Policy
Magnetic Media Policy
Mobile Working Policy
Password Policy
Email Policy
Acceptable Use Policy
Data Protection

That done we move on to Phase 2 which is where we might recommend encryption both at rest and in transit, for critical data assets. We will discuss back up procedures and processes which will ensure that backups are securely stored and that restoring from backups is practiced and works. We will discuss incident handling procedures and business continuity planning. Finally, we will discuss monitoring and audit, two things that until quite recently tended to be out of the price range of SMEs. However, there are now systems and services on the market which are affordable.

This all seems a bit daunting, but if taken in chunks and phased over perhaps several budgetary periods it is doable, and you really need to consider it.

Ransomware – The Threat That Keeps On Giving

I know I’ve banged on about this quite a bit recently, but I make no apologies for it. It has sprung to the front again following the Panorama programme on Monday night which highlighted the often catastrophic effects of ransomware on companies, and had interviews with the National Cyber Security Centre (NCSC) and the National Crime Agency (NCA), with an NCA rep saying that 2025 is shaping up to be the worst year ever for ransomware and the CEO of NSCS calling on businesses to face up to the issue and sort out their cyber defences.

The programme highlighted that Ransomware as a Service (RaaS) now enables less skilled attackers to run ransomware, complete with support and updates. Over 70% of attacks now use these services.

Attackers have shifted to double/triple extortion schemes, encrypting data, threatening to leak it, and sometimes targeting associated partners or customers. Next-gen ransomware, e.g. LockBit 4.0, BianLian etc, is rolling out advanced stealth, data theft, and automated lateral movement techniques, using an initial breach to jump across to other parts of your network or that of your partners and customers.

You’ll have to forgive me for being a bit smug as the programme highlighted issues that I’ve been talking about for a long time now. Firstly, it’s not just the corporates that are targets for this. SMEs are also very much in the firing line. The programme highlighted an example I’ve quoted before. Knight of Old (part of the KNP Logistics Group) suffered consequences that they just couldn’t recover from.

In June 2023, the Akira ransomware gang infiltrated the company via stolen credentials and encrypted critical systems, including freight-tracking, payments, and internal servers, displaying this chilling message:

“If you’re reading this, it means the internal infrastructure of your company is fully or partially dead.”

The group also threatened to release over 10,000 confidential documents (payroll, invoices, financial files) as a form of double extortion. Despite having cyber insurance and backups, they couldn’t fully restore financial systems, and some backups were also destroyed. Insurers covered only the initial cleanup (~£250k) and $1M policy, but this fell far short of covering the estimated $2.7–$5.3 million ransom or the broader economic damage. Operational disruption prevented them from producing reports and financial statements, essential for securing bank funding. A sale fell through, as buyers wanted director guarantees they couldn’t offer.

The company entered administration in September 2023 and ceased operations. Around 730 out of 900 employees lost their jobs, including many long-serving drivers and staff who were owed unpaid wages. Local impact was severe: furloughed staff lost homes, cars, and some experienced severe personal hardship.

It appears that the attack was perpetrated via a weak password and the absence of multi-factor authentication (MFA), with the gang using a brute force method to crack the password. It underscores the fact that even companies with cyber insurance and accredited systems are vulnerable.

Obviously, we’re not party to the full facts but the company’s directors have been quite candid in interview, and we have to wonder if something as simple as good cyber awareness training and the introduction of MFA could have stopped this attack in its tracks. There are other factors to consider though. The backups seemed to have failed, with some of them being destroyed by the attack, suggesting that these backups were on the same network as the main system.

Clearly what is needed is defence in depth, based on the tried and tested method of risk management. The idea of defence in depth stems from military defences, where there are multiple layers to a defensive system. In cyber security we talk about People, Process and then Technology. I’ll once again trot out the quote from Bruce Schneier, ‘If you think technology will solve your cyber security problem, you don’t understand the problem and you don’t understand the technology’. This aligns very well with the opinion of both NCSC and NCA that the majority of these attacks are more in line with scams than with technical hacking.

Rather than bore you with the components of risk management in cyber, I’ll just point you towards a short video we produced on the subject.

Risk Management – a short video

We produced another video which highlights social engineering. That is the method by which much of these attacks are undertaken which are not particularly technical in nature. It’s the People part of the risk management process and is arguably the quickest and cheapest win any company can take. It’s a continual source of wonder amongst cyber security professionals that a large focus remains on technology whilst ignoring this vital element. Our short video tries to hit the highlights but in this changing landscape, we haven’t hit them all.

Social Engineering – A Short Video

The takeaway from this should be that no one is safe or immune from a ransomware attack, particularly ransomware as a service. This latter means that the attacker doesn’t need to be technically proficient, just determined. It enables attackers to target multiple companies at once. If they, for instance, attack 1000 companies at the same time, using the same service, and ask for moderate amounts of ransom, they only need to hit around a 40-50% success rate to make a decent profit. Add in AI which makes this so much easier to do, and you’ve got an idea of how much of a business this is for criminal and nation state sponsored gangs.

Do CISOs have a role in the Small to Medium Enterprise?

A Chief Information Security Officer or CISO, is a post you almost never find in an SME, even those at the top end of that sector. This has contributed to the growth of what is known as fractional appointments i.e. appointments that are not full time with the incumbents often taking roles in more than one organisation, thus the term Fractional.

Anyone taking any role in an SME management team will need to be pragmatic, practical and bring cost effectiveness to their discipline. The CISO role is no different and is all about managing risk, enabling the business and ensuring trust in a very cost sensitive environment.

The CISO can play a crucial role in an SME by ensuring that the organisation’s information and data assets are secure. While the CISO role in a large corporation may be more siloed or focused on strategy, in an SME the CISO often wears multiple hats, balancing strategy, operations, and hands-on technical work.

Challenges Unique to SMEs

I’ve often talked about the challenges that SMEs face, focusing as I do on cyber security. Let’s just have a quick recap looking at where the CISO fits in with these unique challenges.

Limited budget and staff: This is the main reason why SMEs will not employ a full time CISO, they simply can’t afford it. The other being that an SME probably doesn’t require a full-time resource anyway. Because of this lack of resource the CISO may also act as a hands-on security engineer or IT lead, perhaps liaising with a contracted IT outsourcer.
Lack of security culture: Many SMEs don’t prioritise security until after a breach. The CISO will be able to raise awareness and provide advice and guidance before the fact.
Rapid growth and change: Scaling securely is a key challenge as SMEs expand and there are often gaps left because of overlooking the need to embed security at the design stage. The CISO can plug that gap.

Let’s take a look at the potential elements of a job description for the role of a CISO, or a Fractional CISO, in an SME. Of course, these may not fit everyone and it’s more of a menu for SMEs to choose from:

Developing and Leading the Cybersecurity Strategy
Define the overall information security roadmap aligned with the SME’s business goals.
Balance security with business agility, in other words making sure security does not get in the way of business and keeping in mind budget constraints typical in SMEs.
Ensure the strategy addresses risk management, compliance, and data protection.

Risk Management and Assessment
Identify and assess cyber risks relevant to the SME (e.g., phishing, ransomware, insider threats).
Conduct regular vulnerability assessments and penetration tests.
Prioritise risks based on business impact and likelihood.

Policy and Compliance Management
Develop and enforce security policies, standards, and procedures.
Ensure compliance with relevant regulations (e.g., GDPR, PCI-DSS etc depending on industry).
Prepare for audits and provide documentation to demonstrate compliance.

Security Awareness and Training
Conduct regular security awareness training for employees.
Create a culture of security by promoting best practices (e.g., strong passwords, phishing awareness).

Incident Response and Business Continuity
Develop and maintain an incident response plan.
Lead the response to security breaches and minimise damage.
Ensure business continuity and disaster recovery plans are in place and tested.

Technology Oversight and Vendor Management
Evaluate and implement cybersecurity tools (e.g., firewalls, endpoint protection etc).
Manage relationships with third-party vendors, especially cloud providers and MSSPs.
Ensure that vendors comply with the SME’s security requirements.
Ensure the SME itself is not in conflict with any security requirements of larger organisations if it is in that organisations supply chain.

Board and Executive Communication
Translate technical risks into business language for senior management.
Report regularly on security posture, incidents, and needs.
Advocate for security budget and resources in line with organisational risk appetite.

I hope that gives a feel as to why an SME might want to consider a Fractional CISO or Board Advisor. Cyber-attacks are becoming more sophisticated, faster and harder to repel. It is no longer just the corporates who are in the firing line. Modern, often AI driven attacks have put everyone in the sights of the modern cyber-criminal and even from those criminal organisations that are nation state funded. It’s never been more crucial to have professional advice and guidance on tap.

How Should SMEs View Cyber Security?

We experience a quite varied attitude amongst SMEs to cyber security. There is still a prevalent view that they are not really a target because they’re not worth it, and we’ve commented again and again that this is simply not so. SMEs are considered low hanging fruit amongst cyber criminals simply because they tend to have weaker defences and don’t have easy access to the right levels of advice and guidance.

Good cyber defences can be seen in a similar light to insurance. Whilst you hope that you’ll never need it, you understand that it’s safer to have it and in turn, the insurance company will require you to meet certain requirements for your policy to remain extant.

100% protection against an attack is simply not possible and no responsible cyber security company will guarantee that. But we do try and empower businesses by forging intelligent defences to protect them in an ever-evolving threat landscape, being made more dangerous as criminals adopt AI in greater numbers.

SMEs face many of the same cybersecurity threats as large organisations, but they are often more vulnerable due to limited resources, staff, and awareness. So far it’s being reported that the biggest cybersecurity threats to SMEs in 2025 include:

Phishing & Social Engineering

What it is: Deceptive emails, texts, or calls that trick employees into revealing credentials or installing malware.
Why it matters for SMEs: They often have no formal training or tools to detect phishing. A single click can lead to a major breach.

Ransomware Attacks

What it is: Malware that encrypts data and demands a ransom for decryption.
Why SMEs are targets: They’re seen as “soft” targets, less likely to have backups or strong defences, more likely to pay.

Business Email Compromise (BEC)

What it is: Fraudsters impersonate executives or vendors to trick employees into sending money or sensitive data. Traditionally done by email spoofing, now increasingly being done by AI impersonation.
Why it’s dangerous: BEC is low-tech but high impact, no malware, just manipulation. Losses can be substantial.

Poor Password Hygiene

Common issues: Weak, reused, or shared passwords; lack of multi-factor authentication (MFA).
Impact: Credential stuffing and brute-force attacks are easy ways into SME systems.

Unpatched Software & Systems

What it is: Outdated software with known vulnerabilities.
Why it happens: SMEs often delay updates due to compatibility fears or lack of IT resources.
Real threat: Attackers automate the search for these flaws.

Supply Chain Attacks

What it is: Attackers target less secure vendors or partners to infiltrate your network.
Relevance: SMEs often rely on third-party services (e.g. MSPs, cloud tools), but don’t vet their security rigorously. Check their Ts&Cs, what are they responsible for and what are you responsible for? This is becoming a big issue amongst those with critical supply chains of which SMEs may be a part.

Insider Threats (Malicious or Accidental)

Malicious: Disgruntled employees stealing or sabotaging data.
Accidental: Well-meaning staff misconfiguring systems or clicking unsafe links.
Problem: SMEs rarely have monitoring tools in place to catch insider issues early.

Insecure Remote Work Infrastructure

Examples: Unsecured Wi-Fi, lack of VPNs, personal device use (BYOD).
Why it’s risky: Many SMEs embraced remote/hybrid work without upgrading their security posture.

Lack of Cybersecurity Training

Result: Employees don’t recognise threats or understand basic security practices.
Impact: Human error is still a major cause of breaches. Cyber Awareness Training is arguably the biggest and cheapest quick win an employer can take.

Cloud Misconfigurations

Common mistake: Leaving cloud storage exposed to the internet.
Why it happens: SMEs may lack specialised cloud knowledge or rely on default settings. Check with your supplier.

Bonus: AI-Powered Attacks

Emerging trend: Attackers use generative AI to craft more convincing phishing emails, deepfakes, and automated reconnaissance. Check out our earlier blog on this subject (An increase in sophistication of cyber-attacks).
Why SMEs should care: These tools lower the barrier for attackers and increase the success rate of scams.

What practical advice would we have for SMEs? Obviously, that depends on the SME, their vertical, how they operate etc. But generally:

Enable MFA everywhere.
Train staff regularly.
Keep software up to date.
Back up data (and test recovery).
Use endpoint protection.
Identify where all your sensitive data resides.
Investigate protective monitoring services.
Investigate Cyber Security Insurance.
Hire or consult a cybersecurity professional, even part-time.

An Increase in sophistication in cyber-attacks in 2025

There is a lot of discussion about AI, it’s benefits to society in general and its undoubted downside. It’s a fascinating subject and AI can really become the gift that keeps on giving, but a downside for those of us concerned with cyber security, and really that should be all of us, is that we’ve always played catch up to the cyber criminals, trying and often failing to anticipate what the next attack will be, what the next series of attacks will be. Will it be ransomware, denial of service or perhaps a new and more sophisticated scam? Who knows? And there is no doubt that AI is raising the bar.

I have talked a lot about the re-emergence of the script kiddie and how AI in enabling this breed of wannabe criminals. For those who maybe don’t now, a script kiddie was a low level, part skilled hacker, who downloaded scripts from the dark web, put there by the more competent hacker who hoped to sell them. The script kiddie would use those scripts to try and attack targets. But it’s also true that the more skilled and sophisticated criminal is making use of AI and finding new and innovative ways of relieving you of your hard-earned cash.

What we are seeing in 2025 is an era where cyber‑attacks are AI‑powered, highly targeted, automated, supply‑chain enabled, multi‑stage, and geopolitically driven. These attacks exploit weaknesses across credential systems, zero‑day exploits, deepfake tools, and ransomware as a service (RaaS) platforms.

We are in an accelerating digital arms race that calls for AI‑driven defence capabilities, real‑time insights, deception environments, zero‑trust architectures, and quantum‑safe cryptography.

a. AI-powered precision and scale

Cybercriminals are leveraging AI to automate vulnerability scans at astonishing speeds, up to 36,000 scans per second, resulting in massive volumes of stolen credentials (1.7 billion) and drastic upticks in targeted attacks.
AI is also generating hyper-realistic phishing messages, deepfake audio/video, and even “CEO fraud” to manipulate individuals into transferring funds, like a deepfake trick that siphoned US $25 M in Hong Kong.

b. Ransomware as a Service (RaaS) 3.0

RaaS platforms now enable less skilled attackers to run ransomware, complete with support and updates. Over 70% of attacks now use these services.
Attackers have shifted to double/triple extortion schemes, encrypting data, threatening to leak it, and sometimes targeting associated partners or customers.
Next-gen ransomware, e.g. LockBit 4.0, BianLian etc, is rolling out advanced stealth, data theft, and automated lateral movement techniques, ie using an initial breach to jump across to other parts of your network or that of your partners and customers.

c. Supply‑chain & third‑party infiltration

Attacks starting via third-party software or vendors (e.g., SolarWinds-style) allow hackers to move laterally into networks and compromise multiple organisations simultaneously.

d. State‑sponsored & geopolitical cyber warfare

Nation-states (China, Russia, Iran, North Korea) are not just using espionage but now partnering with ransomware gangs to conduct financially and politically motivated operations.
Iranian state-aligned hackers are conducting sophisticated credential theft, MFA bypass, lateral infiltration, DDoS, website defacements, and disinformation across geographies.

e. Zero‑days and living‑off‑the‑land

Exploit kits now rapidly find zero-day vulnerabilities, especially in cloud environments, to bypass patching cycles.
Attackers increasingly use built-in legitimate software and system tools (living off the land) to evade detection.

f. Credential theft resurgence

Reported credential theft incidents rose 300% from 2023 to 2024, with 25% of malware focused on stealing login data.
These stolen credentials are a gateway for automated brute‑force, lateral movements, and supply‑chain infiltration.

g. Targeting of IoT, OT & mobile platforms

Millions of IoT and OT systems (from manufacturing to agriculture) remain insecure and are now common targets of AI‑driven automated attacks.
Mobile‑specific ransomware is emerging; threat actors are developing malware to extort victims directly via their mobile devices.

h. Rise of deception technology and defence adaptability

In response, organisations are deploying deception tech (honeypots, decoys) to detect lateral intrusions or zero-day exploits in real time.
Proactive threat intelligence, zero‑trust frameworks, AI‑driven detection, and adoption of post‑quantum cryptography are becoming critical defensive measures.

SMEs still have the mind-set that these attacks are just about the corporate sector and that they are safe because they are small and not worth targeting. Wrong. SMEs are considered low hanging fruit because they typically spend much less on their defences and tend not to have access to the right levels of support and advice. SMEs make up over 90% of the UK GDP, that’s huge and it makes them worth attacking if, for example, a nation state wanted to cripple the UK economy. AI automation makes this much easier to achieve and attackers at all levels can leverage AI to automate attacks against multiple SMEs at the same time using the same methods. If they attack 1000 SMEs at once, and get a 50% hit rate, that is good business for them.

We are seeing AI letting attackers scan thousands of targets at once, deploy malware bots and use brute force tools. They are automating phishing and social engineering allowing them to deepfake audio and video, using cloned voices to mimic senior personnel in companies. Don’t be lulled into a false sense of security, AI makes this a relatively easy thing to do, doesn’t take high levels of skill, and is highly automated.

There is a real fear that traditional firewalls and spam filters used by most SMEs may fail to detect these advanced threats.

In summary AI-driven cyberattacks pose a significant and growing threat to small and medium-sized enterprises (SMEs). While larger corporations may have the resources to defend themselves, SMEs are often more vulnerable due to limited cybersecurity budgets, staffing, and expertise.

DO YOU HAVE A HANDLE ON CYBER SECURITY?

Over the years I’ve had some very interesting conversations with several people from multiple different verticals, many fitting comfortably within the SME bracket, around Cyber Security. The conversations tend to take a very familiar turn. The cry of, ‘I’m covered, my IT support company has put in a firewall and some anti-virus. They tell me all is good’. Slightly depressing but hardly surprising.

So why surprising? A lot of IT Support Companies providing managed services do a very good job of supplying and implementing networks and providing hardware and software. The Cyber Security field is one where resources are scarce and expensive. Cyber Security professionals take a very different view than IT support companies and come at security from the risk managed view and recognise that it is not just about technology and in fact, it’s about people, process and then technology. More about this below.

As we travel around and visit clients or potential clients, it is common to find that they have the view that adequate security is provided by technology. They rely on their IT provider to provide the guidance they need which tends to involve firewalls, anti-malware software and perhaps a backup regime. All well and dandy. I use a quote from Bruce Schneier, Fellow at the Berkman Center for Internet & Society at Harvard Law School, quite a bit, it goes like this:

‘If you think technology can solve your security problems, then you don’t understand the problems and you don’t understand the technology’.

A common misperception is that IT Security is the same as Cyber Security. That surprises a lot of people, so let’s explore it a bit. There is clearly a close symbiotic relationship between the two disciplines. I would argue, and I know this might meet with some disagreement, that IT security refers to traditional IT security methods which are technology based. Such as firewalls, anti-malware, end point protection etc. Whilst Cyber security is based very much on risk management which combines controls which are both non-technical and technical, following the principles of People, Process and Technology. A good cyber security professional will have a good handle on both approaches.

Even though cyber security and data protection have leapt to the top of many people’s agenda in recent years it is still common amongst many SMEs to believe that it is an IT problem, a technical problem rather than a business issue, even when recognising that the risk of a cyber intrusion or a data breach, impacts the business, the bottom line.

Since I first wrote about this, we now have the changing landscape of working practices. Many SMEs have adopted a more flexible approach to work and are utilising a more hybrid working pattern with some working from the office, some from home and other places. This does have financial advantages for an SME but brings with it a lot more security issues which many are either parking or outright ignoring.

The National Cyber Security Centre (NCSC), a department of GCHQ Cheltenham, estimated, before the hybrid working pattern starting to bed in, that if you are an SME then you have around a 1 in 2 chance of experiencing a cyber security breach. For the small business this could result in costs of around £1400, for the medium business, considerably more. One has just been hit for around £30000, which I am sure you will agree, can be extremely damaging to the bottom line of businesses operating under tight margins. And of course, it’s not just financial penalties but the reputational damage should your customers data and assets be affected as well.

Within the SME world there is an almost total reliance on third party IT providers. Is that a good thing, after all that’s in the IT providers area of expertise and responsibility, isn’t it? And here comes the controversial bit. Third party IT providers, particularly in the SME space, are pretty much exclusively value added resellers or VARs, i.e., companies that sell other company’s products. Now I’ve no problem with that per se, but it comes with issues. Notable amongst them is that these companies will have skill sets that are very much limited to the products they sell. Ie they are proficient in the installation and configuration of those products and their clients are offered those products whether they are best in class, or more importantly, whether they are the most appropriate for the task. Before I get a social media pile on, I know that some of the bigger VARs do sell multiple vendors products, but they are in a minority.

Before we go any further, let’s briefly explore some issues that are common amongst SMEs. Some common myths first:

Small to medium size businesses are not worth attacking.
Cyber Security is an IT Issue.
Technology will keep me safe.
My policies and procedures are up to the job.
My staff are young and have been brought up with IT. They know the score.

Now let’s look at some of the more common issues that we see often amongst SMEs:

Lack of awareness around the current real-world cybersecurity risks
False sense of security, with a heavy reliance and dependence on an external IT third-party provider
Lack of cybersecurity knowledge and understanding
Poor cybersecurity maturity and posture within their businesses
Lack of staff training (at all levels) – just like Health & Safety, cybersecurity is everyone’s responsibility.

Here at H2 we offer a cyber maturity assessment that is designed specifically for SMEs. It is a comprehensive evaluation of an organisation’s cybersecurity capabilities and readiness to effectively mitigate and respond to cyber threats. It involves a detailed analysis of the organisation’s cybersecurity policies, procedures, technologies, and practices. The assessment aims to identify potential vulnerabilities, weaknesses, and areas for improvement in the organisation’s cybersecurity posture.

During the assessment, cybersecurity experts typically examine various aspects, such as:

Governance and Management: Reviewing the organisation’s cybersecurity policies, risk management frameworks, and leadership’s commitment to cybersecurity.

Security Awareness and Training: Evaluating the level of cybersecurity awareness among employees and the effectiveness of training programs.

Technical Controls: Assessing the implementation and effectiveness of security technologies, such as firewalls, intrusion detection systems, antivirus software, and encryption mechanisms.

Incident Response and Recovery: Analysing the organisation’s incident response plan, including procedures for detecting, reporting, and responding to cyber incidents.

Security Risk Management: Evaluating how the organisation identifies, assesses, and manages cybersecurity risks.

Third-Party Risk Management: Assessing the organisation’s approach to managing cybersecurity risks associated with third-party vendors and partners.

Compliance and Regulations: Verifying the organization’s compliance with relevant cybersecurity regulations and industry standards.

The results of the Cyber Maturity Assessment provide valuable insights to the organisation, enabling them to enhance their cybersecurity defences and establish a more robust and resilient security posture. It helps organisations prioritise their investments in cybersecurity, address vulnerabilities, and strengthen their overall cyber resilience and provides a road map to reach a standard agreed with the management, taking full account of that managements risk appetite.
