The cis-UnauthorizedAPICalls alarm fired on a single breaching 5-min period (1/1), so any CloudFormation/CDK deploy burst of benign describe-API denials or a one-off console fat-finger paged and self-recovered, producing notification storms (~17 flips on 2026-06-10). Require 3 consecutive breaching periods so only sustained unauthorized activity alarms; CIS detection of a real persistent problem is preserved (detection window up to ~15 min). Per-control override so the other 14 CIS alarms keep their 1/1 sensitivity (templates untouched). GPT-4.1 cross-review: no blockers (documentation FIX noted re: detection latency). |
