We are following the NIST incident response lifecycle: preparation, detection, containment, eradication, recovery, and lessons learned. we are in the analysis phase, containment is underway, eradication is complete, recovery is in progress, post-incident review is scheduled.
It is 2 AM, the SIEM is screaming, and your manager asks which phase of the NIST incident response lifecycle we are in. Suddenly you need more than technical skills. You need the right words, fast.
Whether you are updating the war room, briefing executives, or writing the postmortem, how you talk about each phase shapes how much people trust the process. The NIST framework gives you structure. Your communication gives it life.
