Post-Incident Review

The final phase is all about learning and improving. A post-incident review helps organizations understand what happened and how they can prevent similar incidents in the future. It's a time to reflect on what worked, what didn't, and how to strengthen defenses.

Review Questions:

• What went well and what didn't?
• How could the incident have been avoided?
• What improvements can be made to processes and policies?

By following these phases, organizations can effectively manage security incidents and bolster their defenses against future threats. Next, we'll explore some best practices for ensuring your incident management process is as robust as possible.

Best Practices for Effective Incident Management
