R36 — Log Retention / Audit-Trail Failure

Insufficient retention, gaps in critical event coverage, or tampered logs leave incidents un-investigable and audits failable. Detection (centralized logging, integrity monitoring) plus prevention (write-once storage, retention policy) are the dominant controls. Residual remains because logs are only as good as what the source emits, and many SaaS apps emit very little by default.

Real-world parallel

Log retention / audit-trail failure is the risk that you detect an incident but can't reconstruct it. Common in cost-pressured environments where SIEM ingest budgets get cut and detection-engineering coverage shrinks. Real consequences land when regulators or insurers ask for the logs. Worst-case discovery: the incident happened months ago and the relevant logs aged out.

How do security teams mitigate Log Retention / Audit-Trail Failure?

The dominant subscore levers for this risk are:

• Detection subscore — weight 40%
• Prevention subscore — weight 20%
• Response subscore — weight 15%
• Recovery subscore — weight 5%

Residual offset: +10 exposure points are structural — no product fully removes them. Real-world parallels: zero-day windows, vendor monoculture, regulator unpredictability.

Why does Log Retention / Audit-Trail Failure matter to a CISO?

Governance risk is the structural risk that lives in audits, attestations, and board reporting. Log Retention / Audit-Trail Failure is the kind of risk that lands a CISO in front of a regulator regardless of how well their controls actually work.
