Security Metrics and Observability Questions

Explain how to instrument systems and automation to produce actionable telemetry, define key security metrics, and use those metrics to drive continuous improvement. Core topics include mean time to detect, mean time to remediate, detection coverage, false positive rate, coverage of scanning and patching, logging and telemetry design, dashboard and alerting strategies, alert tuning and escalation playbooks, and demonstrating return on investment for security improvements. Discuss how metrics inform prioritization, reduce alert fatigue, and feed feedback loops for policy and tooling adjustments.
