Explanation

The post-incident analysis pinpointed a specific breakdown: the handoff from detection to the correct team was slow, causing greater impact. Improving the incident triage process directly addresses this identified bottleneck. Implementing a SIEM (A) would enhance detection capability, but detection was already working well. Documenting lessons learned (B) records what happened but does not fix the process. Documenting prevention and containment steps (D) targets different phases than the one that failed. The fix must match the root cause.
