2) Enable Multi-Factor Authentication (MFA)

MFA adds a critical layer of security by requiring an additional verification step beyond passwords.

3) Secure Email Systems

Email remains the most common attack vector. Use spam filtering, phishing detection, and staff awareness training.

4) Protect Endpoints & Devices

Install antivirus and endpoint protection on all business devices, including laptops used for remote work.

5) Keep Systems Updated

Apply security updates and patches regularly to operating systems, applications, and devices.

6) Backup Critical Data

Use automated backups and test recovery regularly. Follow the 3-2-1 backup rule where possible.

7) Prepare a Disaster Recovery Plan

Have a clear plan for restoring systems and operations after a cyber incident or outage.

8) Control User Access

Grant staff access only to systems they need for their role. Remove access promptly when roles change.

9) Train Employees on Cyber Awareness

Human error is a major risk factor. Regular training helps staff identify phishing and suspicious activity.

10) Monitor & Review Security Regularly

Cybersecurity is not a one-time task. Review controls, logs, and risks regularly.
