Intro to CSEadvanced
Arrange the standard phases of the incident response lifecycle in the correct chronological order, from initial readiness through post-incident improvement.
Answer
Prepare resources and train personnel, Detect and analyze the incident, Contain and mitigate the threat, Recover and restore affected systems, Conduct a post-incident review and document lessons learned
Explanation
### The order
1. **Prepare and train the people who will manage incidents**: readiness must exist before an incident occurs.
2. **Identify and analyse the incident**: the organisation needs to understand what is happening before selecting a response.
3. **Coordinate communications and response activity**: people and stakeholders need aligned instructions and information.
4. **Mitigate the incident's impact**: actions limit continuing harm.
5. **Restore systems and operations using tested recovery plans**: recovery returns required services to use.
6. **Review measures and lessons to improve future plans**: evaluation informs improvement after the event or exercise.
### The concept
Actual incidents may require steps to overlap or repeat. This order represents the broad logic of preparedness, response, recovery, and improvement rather than a rigid checklist for every event.
### Remember
Prepare first, manage and limit the incident, restore service, then learn from the outcome.
