Review security updates frequently.

Security Updates: Your First Line of Defence

Security updates aren’t just patches, they’re shields that block attackers from exploiting known weaknesses. Outdated software is one of the most common attack vectors, and SMBs can’t afford to leave doors open. Updates should be routine, essential, and as natural as brushing your teeth.

Top Tips for Staying Updated:

1. Review Updates Weekly

   • Prioritize operating systems, browsers, plugins, and third-party libraries.

   • Don’t forget firmware on routers, firewalls, and IoT devices.

2. Automate Where Possible

   • Turn on automatic updates for mainstream software.

   • Use centralised patch management tools if managing multiple devices.

3. Subscribe to Vendor Advisories

   • Sign up for security alerts from Microsoft, Apple, Google, and key suppliers.

   • Follow trusted sources like NCSC (UK) or CISA (US).

4. Always Test Before Deploying

   • In business environments, test patches on a non-critical system first.

   • Create a rollback plan in case an update causes issues.

5. Track and Audit

   • Maintain an inventory of all software and devices in use.

   • Run quarterly audits to ensure nothing has been missed.

6. Close the Gaps

   • Uninstall unused or outdated applications.

   • Replace end-of-life software (e.g., Windows 7, old Java versions).

7. Educate Your Team

   • Remind staff not to click “Remind Me Later” on updates.

   • Make patching part of their responsibility, not just IT’s job.

Remember: Every missed update is like leaving a window open overnight. Attackers don’t need to break in if you’ve already left the door ajar.
