Hints
- 💡Follow NIST IR lifecycle structure.
Common Pitfalls to Avoid
- ⚠️Failing to mention crucial phases like 'Preparation' or 'Lessons Learned,' which are foundational for a mature process.
- ⚠️Not clearly articulating the 'why' behind the process, such as minimizing downtime, reducing MTTR, or building resilience.
- ⚠️Focusing too much on specific technical solutions rather than the overarching process and its management aspects.
- ⚠️Neglecting to emphasize the critical roles of cross-team communication and specialized tooling.
- ⚠️Presenting the phases as a rigid, linear checklist instead of an iterative process that feeds into continuous improvement.
Potential Follow-up Questions
- ❓What’s MTTR vs MTTD?
- ❓How do you handle incident retrospectives?
