What is Learning From Information Security Incidents?
ISO 27001 Learning from information security incidents is the process of reviewing and analysing what happened during a security breach or event to understand its causes and consequences. The goal is to improve an organisation’s defences and prevent similar problems in the future. It’s about turning a negative event into a positive learning experience.
Examples
An organisation has a data breach where customer information is stolen. After the incident is contained, the security team holds a meeting to discuss what went wrong. They might find that the breach happened because an employee clicked on a phishing email. They then decide to create better training programs about phishing for all employees. This is an example of learning from an incident.
Context
Learning from incidents is a key part of information security management. It helps organisations to be more resilient. By studying past mistakes, a company can fix weaknesses in its systems, improve its security policies, and train its staff better. This makes the company safer from future attacks. It’s a cycle of action, review, and improvement.
