A SIEM parser update normalizes timestamps

Parsing improved and correlation quality collapsed in the older rule set. The explicit configuration seems correct, yet an inherited policy no longer resolves the same way under the cleaned hierarchy. Effective ownership looks correct at first glance, but one delegated path still reflects the old hierarchy. Nominal permissions look aligned, yet one delegated control path still reflects the retired operating model.

• Identify the primary failure signal in the Incident Response scenario.
• Separate visible symptoms from the underlying technical dependency.
• Describe the safest recovery path and the follow-up prevention work.

1. Summarize the current impact and the last known change.
2. Collect direct evidence from logs, runtime state, and configuration before changing anything.
3. Separate immediate recovery from permanent prevention work.

Choose the smallest safe recovery action first, then record the prevention work that reduces repeat incidents.
