Security Baselines

Pre defined, vetted configuration sets that establish a known good hardened state for an operating system or application.

IntermediateUpdated 2026-09-01

Overview

Baselines from Microsoft, CIS and DISA STIGs encode hundreds of settings with rationale. Adopting a published baseline and documenting deviations is far more defensible than assembling settings ad hoc.

Baselines must be versioned and reviewed: new OS releases change available settings, and unmanaged drift accumulates quickly across an estate.

Security considerations

  • Pilot baselines before broad deployment; some settings break legacy applications.
  • Record every deviation with a justification, owner and review date.
