Define roles

An incident requires technical, legal, commercial, and executive decisions.

  • Incident owner.
  • Communications owner.
  • Legal and insurance contact.

Preserve evidence

Logs, disk images, and screenshots help understand and prove what happened.

  • Do not reinstall too quickly.
  • Preserve logs.
  • Document actions.

Communicate without worsening

Premature or imprecise communication can create reputational risk.

  • Pre-approved messages.
  • Dedicated internal channel.
  • Decision on regulatory notification.

Frequently asked questions

How long should the plan be?

For an SMB, a tested 5 to 10 page plan is better than a long unused document.

When should an external expert be called?

As soon as there is encryption, possible exfiltration, critical downtime, or notification duty.

Should the plan be tested?

Yes, at least one tabletop simulation per year.
