Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Defining the exact event types to be logged prevents indiscriminate collection of excessive data.
Audit-record reduction and on-demand reporting directly reduce the impact of overly verbose logs during review.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Excessive logging hinders log processing and forensic analysis, largely undermining DE.AE-04's ability to estimate impact/scope via SIEMs or tools while removing most of that outcome's efficacy.
Excessive logging undermines event analysis by flooding logs with noise that hinders processing and forensic review, but does not blind or defeat the outcome the way insufficient logging would.
Excessive logging impairs processing of provided event data and log-analysis findings (one aspect of DE.AE-06) without fully defeating alert/ticket distribution.

A.8.15 directly requires logging to be configured so that only necessary events are recorded, preventing excessive data.
Documented operating procedures can include logging guidelines, indirectly reducing excessive logging.
Monitoring activities can detect excessive logging but do not prescribe how much data should be logged.
