October is Cyber Security Awareness Month, and this year’s theme couldn’t be more relevant for UK small and medium-sized enterprises: simple steps to keep secure online. While cyber threats grow more sophisticated each year, the good news is that the majority of cyber attacks succeed because of basic security oversights, not advanced hacking techniques.
The Reality for UK SMEs
Recent statistics paint a concerning picture. According to the UK government’s Cyber Security Breaches Survey, approximately half of UK businesses experienced some form of cyber security breach or attack in the past year. For SMEs, the average cost of these incidents can range from thousands to tens of thousands of pounds, not to mention the reputational damage and operational disruption.
The misconception that “we’re too small to be targeted” is exactly what cyber criminals count on. Automated attacks don’t discriminate by company size, and SMEs often have valuable data, customer information, and access to supply chains that make them attractive targets.
Five Simple Steps That Make a Real Difference
1. Strengthen Your Password Policy
Weak passwords remain one of the easiest entry points for attackers. Implement a policy requiring strong, unique passwords (minimum 12 characters with complexity), and consider using a password manager across your organisation. Enable multi-factor authentication (MFA) on all business-critical systems, especially email and financial platforms.
2. Keep Software Updated
Software updates aren’t just about new features; they patch known security vulnerabilities. Enable automatic updates where possible, and establish a regular schedule for checking and updating all systems, including operating systems, applications, and firmware on network devices.
3. Educate Your Team
Your employees are both your greatest vulnerability and your strongest defence. Phishing attacks are increasingly sophisticated, targeting staff with convincing emails designed to steal credentials or introduce malware. Regular, practical cyber security training helps your team recognise threats and respond appropriately.
4. Backup Your Data Regularly
Ransomware attacks can cripple businesses overnight. Maintain regular backups of critical data using the 3-2-1 rule: three copies of your data, on two different types of media, with one copy stored offsite or in the cloud. Crucially, test your backups regularly to ensure they can be restored when needed.
5. Secure Your Network
Use a properly configured firewall, ensure your Wi-Fi network is encrypted with WPA3 (or WPA2 at minimum), and create a separate guest network for visitors. Consider implementing network segmentation to limit the potential spread of a breach.
Taking the Next Step
Understanding these principles is one thing; knowing how well your organisation implements them is another. The gap between awareness and action is where vulnerabilities hide.
