Post-Incident Reporting
Part of the Cybersecurity Roadmap
In short
The attack is over, but the job is not. A clear report captures what happened and what to fix, turning a painful incident into lessons the whole team keeps.
Documenting the full incident timeline, root cause, impact, and remediation actions after resolution — closing the loop with a written record that informs future prevention.

Think of it like this
The match review after the game
A cricket team does not just move on after a loss. They review the tape: what went wrong, which plan failed, what to drill before the next match. A post-incident report is that review, written down so the fixes actually happen.
Watch it happen
What a good report covers
1/4Lay out what happened and when, from first signs to full recovery.
The big ideas
What you need to know
A clear timeline
Lay events in order with times. It helps everyone see how the incident unfolded and where delays hurt.
Honest root cause
Name the true underlying reason. A report that blames bad luck fixes nothing next time.
Actions with owners
Every fix needs a named owner and a date, or it quietly never happens.
Written for the reader
Leaders want impact and cost; engineers want technical detail. Good reports serve both, often in sections.
Save yourself the pain
Common mistakes
Oops
Writing a report that blames one person.
Do this instead
Focus on the system and process gaps. Blame makes people hide problems, which causes the next incident.
Oops
Listing fixes with no owner or deadline.
Do this instead
An action without a name and a date is a wish. Assign each one clearly so it actually gets done.
Your mission

What makes follow up actions in a report actually get done?
