Ransomware encrypts an organisation's files and demands payment to unlock them. It can halt operations for days or weeks, so preparation is critical.
Prevention
- Patch systems promptly, especially internet-facing ones
- Use MFA for remote access and email
- Restrict administrator privileges
- Filter suspicious emails and attachments
Preparation
Keep offline or immutable backups that ransomware cannot reach, and practise restoring them so recovery is fast.
Response
Isolate affected machines from the network immediately, preserve evidence, inform leadership and seek expert help. Report the incident to the relevant authorities.
After the incident
Find out how attackers got in, close that gap and update your response plan with the lessons learned.
Organisations with tested backups and a clear plan recover far faster. The best time to prepare is before an attack.
