Do you need help & advice with Cybersecurity?
A recent BBC report highlights a worrying increase in serious cyber-attacks targeting businesses across the UK. This overview is for business leaders, explaining the basics of cyber threats in simple terms and what steps you can take to protect your company. It covers understanding security scores, the difference between scans and tests, and why patching is so important. We’ll also look at preparing a basic incident response plan.
Key Takeaways
- Understand Security Codes: CVE codes identify vulnerabilities, and CVSS scores rate their severity (1-10). A score of 9 or 10 means it needs immediate attention.
- Patching is Vital: Regularly update your systems, especially for critical vulnerabilities. Ignoring them creates openings for attackers, and AI makes exploiting them easier.
- Scans vs. Pen Tests: Vulnerability scanners identify weaknesses, while penetration tests (pen tests) involve external experts trying to break into your network.
- Assume a Breach: Plan for the possibility of a ransomware attack. It can be incredibly costly, potentially wiping out a year’s profit or even more.
- Simple Incident Plan: Have a printed, laminated A4 sheet with key contacts (IT, management, PR), insurance details, and emergency numbers. Keep it accessible.
Understanding Cyber Threat Scores
When we talk about cyber security, you’ll often hear about things like CVE and CVSS. Don’t let the acronyms scare you. A CVE, or Common Vulnerabilities and Exposures, is basically a unique code given to a specific security weakness. Think of it like an ID number for a problem. These codes are usually managed by the US government.
Each of these vulnerabilities is then given a CVSS score. This score, which ranges from 1 to 10, tells technical teams how serious the vulnerability is. If a vulnerability has a score of 9 or 10, it’s considered critical. This means it needs to be fixed urgently.
It’s important to know that these scores can sometimes change, and sometimes critical issues get overlooked. That’s why it’s important for your IT teams to be running vulnerability scanners regularly. These tools help identify potential weaknesses in your systems.
Vulnerability Scans vs. Penetration Tests
It’s easy to mix up vulnerability scans and penetration tests, but they’re different. A vulnerability scan is typically done by a tool that automatically checks your systems for known weaknesses. It’s like a quick health check.
A penetration test, on the other hand, is when an external organisation actively tries to break into your network. They simulate a real-world attack to find security holes that automated tools might miss. Both are useful, but they serve different purposes.
The Urgency of Patching
Every month, companies like Microsoft release updates for their software. These updates often include fixes for newly discovered vulnerabilities. For those critical vulnerabilities with high CVSS scores, it’s essential to get them patched as soon as possible. Leaving them unaddressed is like leaving your front door unlocked.
Attackers can create exploits – ways to take advantage of these vulnerabilities. What’s more concerning is that Artificial Intelligence (AI) is making it much easier and faster for people, even those with limited technical skills, to create and use these exploits. What used to take a lot of programming knowledge can now be learned and done in a matter of weeks, sometimes even days.
Risk Management and Incident Planning
In today’s world, it’s wise to assume that your business will eventually face a cyber-attack, possibly a ransomware incident. These attacks can be incredibly expensive. For large companies, the cost can be millions per hour. For a small business, a ransomware attack could easily cost you your entire year’s profit, or even more than your annual revenue.
This is why having a contingency plan is so important. Think of it like the handbrake in your car. You might not need it every day, but you absolutely need it to be working when you do. A plan helps you manage the situation if the worst happens.
Your Simple Incident Response Plan
We’ve created a simple, one-page document that you can use as your incident response plan. It’s designed to be printed, laminated, and kept near your IT equipment.
This A4 sheet should include:
- Your cyber insurance policy number.
- The emergency phone number for your insurance provider.
- Mobile numbers for your key contacts:
- Your technical contact (who will handle the IT side).
- Your management contact (who will liaise with the board and stakeholders).
- Your PR contact (who will manage communications with staff, customers, and the public).
The PR contact’s role is to explain what’s happening and how the business is responding. This might involve setting up a specific voicemail message for callers.
The main point is to have this information readily available. If your systems are down due to an attack, you won’t be able to access digital documents. Having a physical copy means you can still contact the right people and start the recovery process.
Print it, laminate it, and stick it to your racks. Update it every year. Without this basic plan, dealing with a major incident like a ransomware attack becomes incredibly difficult.
The Changing Threat Landscape
The BBC article mentioned earlier points to an increase in significant cyber threats. These can come from various sources, including state-sponsored actors, but also from individuals, including teenagers, who are using AI to carry out attacks. The ease with which these attacks can now be launched is a major concern for businesses in 2025.
If you want your business to keep operating, having a simple, accessible plan is key. It allows you to communicate with your team and start getting things back to normal.
We’ll be sharing more technical details and tools in future videos, but for now, the most important first step is to download the template, fill it in, and make sure it’s visible and accessible. It’s better to have a simple, practical plan than a complex, unmanageable document.
