Retaining incident timelines and logs in tooling gives a post-incident review the data it needs to reconstruct what happened accurately.
Retaining incident timelines and response records in tooling depends directly on the activity logs A.8.15 requires, so a review can reconstruct what happened.
Retaining incident data for post-incident review analyzes what monitoring already caught, rather than being the detection activity A.8.16 covers.
