ISO 27001 Information Security Incident Management Planning and Preparation is a guideline that helps organisations get ready for and respond to security problems. It’s like having a fire drill for computer security. This control makes sure you have a plan to deal with things like cyber-attacks or data leaks. It helps you act fast to lessen the damage.

Examples

  • Cyber-attack: A hacker gets into your company’s network. Your team uses the ISO 27001 Annex A 5.24 plan to find out what happened, stop the attack, and fix the damage.
  • Data Breach: A file with customer information is accidentally shared with the wrong people. The plan tells you who to tell, how to handle the data, and what to do to prevent it from happening again.

Context

This control is a key part of ISO 27001, which is an international standard for managing information security. It’s about being proactive. Instead of waiting for a problem to happen, you prepare for it. This helps protect your company’s important information.
