Artificial Intelligence – It’s here to stay

Artificial Intelligence is coming more and more to the front in the news, in just about all spheres of IT, no matter the vertical it serves. 

What exactly is AI?

Artificial intelligence (AI) describes computer systems which can perform tasks usually requiring human intelligence. This could include visual perception, speech recognition or translation between languages.

Of course, that’s not the only description you’ll find if you use your best research tool, Google, but it’s one used by the National Cyber Security Centre, so it’ll do for me.

I’m willing to bet that many of you, most of you, have some form of AI app downloaded on your devices.  ChatGPT is arguably the most popular amongst the general populace but it’s not the only game in town.  These apps are becoming more and more available and popular. ChatGPT is an artificial intelligence chatbot developed by OpenAI, a US tech startup. It’s based on GPT-3, a language model released in 2020 that uses deep learning to produce human-like text.  It has an underlying technology that has been around much longer, but this blog isn’t about the technicalities of AI, but more about how it affects SMEs as they go about their business.

I’ve been arguing that perhaps the biggest potential threat in terms of proliferation, ie the number of attacks waged at a relatively low level, aimed at quick wins in terms of scamming money, is the re-emergence of the script kiddie.  I wrote, some time ago, about how code could be written to be inserted into a Ransomware attack, quite easily, using AI. 

Script Kiddie

A script kiddie was what we called someone of relatively low skill levels who would go online to the dark web, and purchase scripts written by more advanced criminals that they had put up for sale.   The script kiddie would then use these scripts to mount an attack on a company or organisation.  These often failed because the script kiddie wasn’t all that bright, but just occasionally, they were harmful and even devastating.

Another scam, reported in The Washington Post, was an update on the very well reported CEO Scam, whereby someone impersonates the CEO of a company using spoofed email, but this time it’s using AI spoofing the CEOs voice, attempting to scam money from the company.  This one worked, and the company lost a lot of money.

So why am I bringing this up again so soon?  Well AI continues to be reported in the news, sometimes with a good result and sometimes not so good.  So, I thought I’d ask Chat GPT what it thought about AI and Cyber Security.  I asked 2 questions, the first was, ‘Is AI a danger in terms of Cybersecurity?’.  The answer came back:

Double Edged Sword

AI can be both a boon and a potential danger in terms of cybersecurity.  On one hand, AI can enhance cybersecurity by detecting and mitigating threats more efficiently, analysing vast amounts of data for anomalies, and automating certain security tasks.  On the other hand, AI can also pose risks if it falls into the wrong hands or is used maliciously.  Sophisticated AI powered attacks could exploit vulnerabilities, evade detection, or launch targeted attacks at an unprecedented scale.  It is crucial to develop robust safeguards ethical guidelines, and responsible AI practices to ensure AI remains a force for good in cybersecurity.

So even ChatGPT thinks this is a double edged sword.  The real problem for my target clientele, the SME space, is that affording AI powered tools to detect and mitigate threats and analyse large amount of data, will seemingly be too costly for them.  But as many defences use AI themselves now, it’s actually quite affordable.  So, when we are talking about developing robust safeguards, understanding the risks becomes even more vital, if that’s possible, than it ever has been before.  It also brings Zero Trust solutions sharply into focus and finding such solutions that are affordable, is going to become crucial.

The next question I asked was, ‘How do we ensure that AI isn’t a cybersecurity threat?’.  The answer came back:

Key Considerations

Ensuring that AI is not a cybersecurity threat requires a multi-faceted approach. Here are some key considerations:

1. Robust Security Measures: Implement strong security protocols, encryption, and access controls to safeguard AI systems and their underlying data from unauthorized access or manipulation.

2. Rigorous Testing and Validation: Thoroughly test and validate AI algorithms and models to identify and fix vulnerabilities, including potential avenues for cyberattacks, before deployment.

3. Adversarial Testing: Conduct adversarial testing to simulate potential attacks and evaluate the resilience of AI systems against different cybersecurity threats.

4. Data Privacy and Governance: Establish clear policies and practices for data privacy, ensuring that sensitive information is properly handled, stored, and shared in compliance with relevant regulations.

5. Ongoing Monitoring and Updates: Continuously monitor AI systems for potential security risks, promptly address vulnerabilities, and keep software and hardware up to date with the latest security patches.

6. Ethical AI Development: Integrate ethical considerations into the design and deployment of AI systems, emphasizing transparency, fairness, and accountability to mitigate potential biases or unintended consequences.

7. Collaboration and Information Sharing: Foster collaboration among industry, academia, and government entities to share knowledge, best practices, and emerging threats, enabling a collective effort to combat AI-related cybersecurity challenges.

8. Education and Awareness: Promote cybersecurity awareness and provide training to AI developers, users, and stakeholders, emphasizing responsible AI usage and the identification of potential threats.

By following these guidelines and continuously adapting to emerging risks, we can enhance the security of AI systems and minimize the potential for them to be exploited as cybersecurity threats.

Next Steps & Relevance

Again, looking at this from an SME perspective, some of it isn’t relevant i.e., No6 for example, SMEs aren’t going to be developing their own AI solutions.  And much of it I would have come up with on my own, without the aid of a machine.  It would appear that AI uses some common sense, which is nice.  No8 for example.  I bang on and on about this.  It is low cost and easy to implement.  It’s staggering how many companies don’t do this. This list also shows the value of Zero Trust solutions and encryption, which on its own, vastly reduces the risk to data, particularly PII (personal identifiable information – UK GDPR).

The argument then is that AI might encourage a proliferation of low level attacks, largely aimed at SMEs who generally have the lowest defences.  Quite low level criminals can utilise AI to carry out attacks that heretofore would have been beyond their skill level.  Common Cyber sense can go a long way to mitigating these attacks.  Technology evolves, attacks evolve, but the basic understanding of threat + vulnerability = risk, has never gone away.  Understand that and you stand a good chance of staying safe.

What Are The Chances of a Cyber Attack Affecting You?

That’s a really good question and one that’s very difficult to pin down.  There are studies galore, mostly from the cyber security industry, and you might feel a little sceptical about those, but also from Governmental sources, which you might consider hold more weight.  Fear, Uncertainty and Doubt, known as FUD, permeates the airwaves about this and it can be a bit of a nightmare separating fact from exaggeration.  And I get that, I really do.

Aviva, not of course a cyber security company but who nonetheless do sell insurance, carried out some research reported in December 2023, which seems, on the fact of it, to be a little more realistic.  They have said that one in five UK businesses have experienced a cyber-attack or incident, with nearly one in 10 (9%) small businesses experiencing this in the last year. This number rises to 35% of large corporate businesses, showing the increasing risk that cyber presents.  But even this has some problems in that it depends on how many businesses reported such an attack or incident.  There is other research that suggests that many businesses, especially SMEs, keep such things well under wraps.

That’s a really good question and one that’s very difficult to pin down.  There are studies galore, mostly from the cyber security industry, and you might feel a little sceptical about those, but also from Governmental sources, which you might consider hold more weight.  Fear, Uncertainty and Doubt, known as FUD, permeates the airwaves about this and it can be a bit of a nightmare separating fact from exaggeration.  And I get that, I really do.

Small Business Cyber Attack Statistics 2024 (And What You Can Do About Them) says that SMEs account for 43% of cyber-attacks annually, of which 46% were SMEs with 1,000 or fewer employees.

In the 2023 Not (Cyber) Safe for Work Report, there are some alarming statistics.  A staggering 97% of executives use personal devices to access work accounts, and 74% frequently send work-related emails and texts from these devices.  Behaviour which significantly increases the vulnerability of SMEs to cyber-attacks, putting not just operations at risk but also sensitive employee and customer data.

SMEs are often repositories of a considerable amount of personal and financial information, making them lucrative targets for cyber criminals.  The report further indicates that one in three respondents has fallen victim to data theft via scams.  A single can result in identify theft, financial loss, and severe reputational damage.

This is a suggested list of the top 10 Cybersecurity Threats:

  • Social Engineering (often a precursor to Phishing).
  • Third-Party Exposure.
  • Configuration Mistakes.
  • Poor Cyber Awareness and Practice.
  • Cloud Vulnerabilities.
  • Mobile Device Vulnerabilities.
  • Internet of Things.
  • Ransomware.

Given that many SMEs have now adopted the hybrid working style since COVID, these are not particularly surprising.  Working remotely isolates employees who can be much more easily panicked into doing things that are unsafe, than if they have someone on hand, in the office, they can turn to for advice.  For example, Phishing.  Should I click this, does look a bit iffy?  I’ll ask Fred and see what he thinks.  As opposed to sitting at home, working to a deadline, and getting pressured by well-crafted Phishing emails, and thinking, I’ll just do it, what’s the worst that can happen?

One of the major problems facing all sizes of business is the lack of cyber security skills available for hire, either as an FTE or a contractor.  Shockingly, In September 2023, 50% of all UK businesses had a basic cybersecurity skills gap, while 33% have an advanced cybersecurity skills gap. These figures are consistent with those from 2022 and 2021, highlighting the persistent skills gap issue.

We talked a little bit above, about people using their devices.  This isn’t necessary a major issue, providing the individual is prepared to adhere to some security controls being placed on that device, if it is to be used for work.  It’s a bit of a balancing act.  It is reported that 80% of employees are uncomfortable with the idea of their personal devices being monitored by their companies, yet 73% would consent to having cyber security software installed on their devices.  So, a balanced approach is needed, which respects individual privacy while ensure collective security.  Not easy.

Here are 5 actionable steps we are recommending SMEs take:

  • Employee cyber awareness training.  Probably the biggest and cheapest quick win any SME can and should be taking.
  • Strong access control using multi factor authentication.  This should be a no brainer.
  • Cyber Security audits and monitoring.  Not easy for many SMEs who will be put off by thinking about costs.  However, this has become much more affordable, and all SMEs should be having conversations around this.
  • Encryption.  Again, becoming much more affordable and easier to use.  If your sensitive data is encrypted, the chances of falling foul of data protection becomes much less of an issue.
  • Supply chain security.  Many SMEs are in the supply chains of the bigger companies, often utilising online processes, connecting direct to the customer.  What would happen if a cyber-criminal gained access to a customer of yours, through your systems?

There is no silver bullet for this.  First and foremost, it must be recognised as a business issue, not an IT issue.  It must be owned from the top, and dealt with by the board, as they would any other business issue.  You can outsource your IT management, but you can’t outsource your responsibility.

Protecting Your Business from Cyber Attacks – Part 2 – Plus some info on a Ransomware Attack

efore I begin I thought it would be appropriate first, to discuss an issue that has cropped up in the news, which I believe is extremely pertinent to SMEs, because many use MS365 and Azure in part or in whole, for storing their data and as part of their access controls.  Many IT companies that service SMEs, will claim that Azure provides excellent protections, and that it’s enough on its own.  Now, I’m not here to denigrate Microsoft, heaven forefend, but it would be remiss of me not to point out a recent breach, which might well be a state backed attack, but nonethess has created what is known as an Advanced Persistent Threat (APT), known as Storm-0558 breach.

This breach has allowed China-linked APT actors to potentially have single-hop access to the gamut of Microsoft cloud services and apps, including SharePoint, Teams, and OneDrive, among many others.  It is estimated that the breach could have given access to emails within at least 25 US government agencies and could be much further reaching and impactful than anyone anticipated, potentially placing a much broader swathe of Microsoft cloud services at risk than previously thought.

A lack of authentication logging at many organizations means that the full scope of actual compromise stemming from the situation will take weeks, if not months, to determine.  This of course raises issues with authentication even amongst large enterprises and government departments.  SMEs are far more reliant on such technologies and are subsequently far more at risk.

This breach was caused by a stolen Microsoft account key which allowed the bad guys to forge authentication tokens to masquerade as authorised Azure AD users, and therefore obtaining access to Microsoft 365 enterprise email accounts and the potentially sensitive information contained within.  However, it gets worse, as it turns out that the swiped MSA key could have allowed the threat actor to also forge access tokens for “multiple types of Azure Active Directory applications, including every application that supports personal account authentication, such as SharePoint, Teams and One Drive.

It should be noted that Microsoft took swift action and revoked the stolen key, however despite this some Azure AD customers could potentially still be sitting ducks, given that Storm-0558 could have leveraged its access to establish persistence by issuing itself application-specific access keys, or setting up backdoors.  Further, any applications that retained copies of the Azure AD public keys prior to the revocation, and applications that rely on local certificate stores or cached keys that may not have updated, remain susceptible to token forgery.

OK, now back to the original subject.  Steps 6 to 10 in my suggested top ten list.

  1. What steps should I take to protect my business from ransomware attacks? A very good question with a multi thread answer.
  • Keep Software Updated. Regularly update your operating system, applications, and antivirus software to ensure you have the latest security patches.
  • Use Strong Passwords. Use unique and complex passwords for all your accounts and consider using a password manager to keep track of them securely.
  • Enable Two-Factor Authentication (2FA).  Add an extra layer of security by enabling 2FA whenever possible, as it helps prevent unauthorized access to your accounts.
  • Be Cautious with Email. Avoid opening attachments or clicking on links from unknown or suspicious senders. Be wary of phishing attempts.
  • Backup Your Data.  Regularly back up your important files and data to an external hard drive or a secure cloud service. This way, even if you fall victim to ransomware, you can restore your files without paying the ransom.
  • Use Reliable Security Software. Install reputable antivirus and anti-malware software to help detect and block ransomware threats.
  • Educate Yourself and Others. Stay informed about the latest ransomware threats and educate your family or colleagues about the risks and preventive measures.
  • Secure Network Connections. Use a firewall and be cautious when connecting to public Wi-Fi networks.
  • Limit User Privileges. Restrict user access privileges on your devices, granting administrative rights only when necessary.
  • Monitor for Suspicious Activity. Regularly monitor your devices and network for any unusual or suspicious activity that might indicate a potential ransomware attack.
  1. What can I do to ensure that my data is backed up in case of a cyber-attack? This is straight forward and highlights a problem whereby many SMEs think that if their data is on a cloud service, they don’t need to back it up.    You need a backup routine that separates your backed up data, from your data storage.  What I mean by that, is that if an attacker, or a piece of malware, can jump from one system to another, then having a live connection to your back up defeats the object, but it’s surprising how many people do this.  So, there are a number of methods.  The first is the good old fashioned tape backup.  Becoming less and less used nowadays but still very effective.  Another is that several cloud providers also provide a backup solution that disconnects once the backup has been done and will allow you to go back to a ‘clean’ backup if the current one has been compromised.  Check this out, but do back up your data, don’t be convinced that you don’t need to, you do.
  1. What cyber security measures should I put in place to protect my business from external threats? To protect against external cyber threats, you should consider implementing the following cybersecurity measures:
  • Strong Passwords: Encourage employees to use complex passwords and enable multi-factor authentication wherever possible.
  • Regular Updates: Keep all software, operating systems, and applications up to date to patch known vulnerabilities.
  • Firewall: Set up and maintain a firewall to control incoming and outgoing network traffic.
  • Antivirus Software: Install reputable antivirus software to detect and remove malware.
  • Employee Training: Educate your staff about cybersecurity best practices and potential threats, such as phishing and social engineering.
  • Data Encryption: Encrypt sensitive data to prevent unauthorized access if it gets intercepted.
  • Access Control: Implement role-based access control to limit users’ access to only the data and systems they need.
  • Regular Backups: Regularly backup your important data and keep the backups in a secure location.
  • Network Monitoring: Use intrusion detection and prevention systems to monitor network activity for suspicious behaviour.
  • Incident Response Plan: Develop a comprehensive incident response plan to handle cybersecurity incidents effectively.
  • Vendor Security: Ensure third-party vendors and partners also have strong security measures in place, especially if they have access to your data.
  • Physical Security: Protect physical access to servers and sensitive equipment.
  1. How can I stay up to date with the latest cyber security threats and best practices? There is a number of things you can do but a lot depends on how much time you have available to devote to this.  Probably not much and you may wish to consider having an advisor on tap, and surprise, we provide such an advisor.  But pointers that might want to consider include:
  • Subscribe to reputable cyber security news sources and blogs, like this one!
  • Attend cyber security webinars.
  • Follow cyber security experts on social media.
  • Sign up for security alerts: Many organizations and government agencies offer email alerts for the latest cyber threats.
  • Participate in cyber security training. I can’t emphasise enough the value of cyber awareness training for your staff.
  • Read official reports and advisories: Stay informed about security bulletins and advisories released by software vendors and security organizations.
  • Practice good cyber hygiene: Implement strong passwords, use multi-factor authentication, keep your software up to date, and regularly backup your data.
  1. What steps should I take to ensure my business is compliant with relevant regulations and industry standards?

This is going to depend on several factors, such as the business you are in.  Many organisations must adhere to a variety of standards within their area of business and of course, many use a variety of International Standards such as ISO9000 series.  On top of this there are legal frameworks that you also must adhere to, amongst those are UK GDPR and financial services regulations.  Not an exhaustive list.  It can be a minefield.

It is somewhat surprising to me, that many SMEs that I visit don’t know what data is subject to these regulations and what isn’t, and where that data is actually stored, how it is processed and protected.  They will argue that they do know most of this, at least at a high level, but that they outsource to their local IT provider.  That won’t help you if a regulator comes after you.  You can outsource your IT, but not your responsibility.  Take advice, get guidance, there are some great protections and audit tools out there which don’t have to cost a fortune.  Check them out.

Identity and Access Management

IDENTITY AND ACCESS MANAGEMENT

Today I’m suffering from what is known in the UK, as a stinking cold. I feel like death warmed up, so this week I’ve decided to rehash a piece I did last year, on identity and access management. Those of you who have managed to plough your way through some of my earlier stuff, will know that I am very big on user awareness training for staff at all levels, believing as I do, that it is arguably one of the biggest wins that an SME can gain, to protect themselves against cybercrime. There is however a very close second, and that is identity and access management.

There is mounting evidence that the message is getting through that, although passwords are very important, they most certainly aren’t the panacea that many think they are.  We can see many organisations moving to 2 factor authentication as a norm now.  A charity I volunteer for has recently done just that and not before time, considering the amount of personal data they are holding.  But is that enough?

Compromised credentials are very high on the list of cybercrime related incidents that we see and have to deal with.  Protecting these identities can be a very technical issue and advice and guidance will be needed to ensure that you are adequately covered.  However it needn’t be overly expensive, neither need it be overly complicated.  In fact, I’m a great believer in that the simplest solution is often the best solution.  I’m an adherent of the KISS principle – Keep It Simple Stupid.

Questions to ask yourself include:

  1. Are your user accounts configured with the minimum level of privilege they need to do their job?
  2. If an employee needs additional privilege to carry out a one off job, how do you ensure that once it’s completed, the privilege is revoked?
  3. What is a privileged account? Typically it’s someone who needs additional privileges as part of their daily tasks, such as adding/removing users, auditing actions, access to more secure areas of the network (finance, management data etc), etc etc.  Are you limiting by policy the roles within your organisation that need privileged accounts, and are you specifying explicitly what those privileges are, by role?
  4. Are your privileged accounts subject to greater levels of auditing and scrutiny?
  5. Do you have a joiners and leavers process to manage active accounts?
  6. Do you have a movers process ie employees that change roles and require different levels of access to carry out their new role, either adding or removing privilege?

Another issue that you may need to consider is any accounts that exist on your network that may be used by third party suppliers.  Many companies use ‘just in time’ supply management which can require third parties to have access to their network.  Another example is people like me who, when carrying out things like vulnerability assessments, may be given privileges to scan the network.  Is that revoked at the end of the scan?  And of course, there is the IT company you may have under contract who actively have access to your network to carry out maintenance and might actually also have a contract for controlling user privilege.  Or perhaps the company you have under contract maintaining your alarms and security cameras which you didn’t know were actually using your network to connect to each other and their control room.

What about logging?  What is logging?  Every system has a set of logs which can be switched on or off.  I often come across networks where logging has been switched off or never activated because its consider to be an overhead you can live without.  Well, I disagree with that, quite vehemently.  Logging helps you to determine what normal looks like.  For example user profiles carry out certain functions within their role.  If a user is stepping outside of that profile, you need to find out why.  Is it a user who is doing something they simply didn’t realise they shouldn’t, or is it something more serious?  Is it an identity that has been created or hi-jacked by a cybercriminal who has managed to gain access?  Examination of these logs will help you understand that.  There is of course software on the market that will be of great help with this.

And of course, what do you do if you are suspicious of an activity or action by a user?
