Overview#
Defensive security team responsible for monitoring, detection, and response. Builds detections, runs investigations, and partners with engineering to close control gaps.
Core objectives#
- Establish shared definitions of Blue Team for security, engineering, and leadership teams.
- Connect Blue Team activities to measurable risk reduction and resilience goals.
- Provide onboarding notes so new team members can quickly understand how Blue Team works here.
Implementation notes#
- Identify the primary owner for Blue Team, the data sources involved, and the systems affected.
- Document the minimum viable process, tooling, and runbooks that keep Blue Team healthy.
- Map Blue Team practices to standards such as ISO/IEC 27001, NIST CSF, or CIS Controls.
Operational signals#
- Leading indicators: early warnings that Blue Team might degrade (e.g., backlog growth, noisy alerts, or missed SLAs).
- Lagging indicators: realized impact that shows Blue Team failed or needs investment (e.g., incidents, audit findings).
- Feedback loops: retrospectives and metrics reviews that tune Blue Team continuously.
Related practices#
- Align Blue Team with defense-in-depth planning, threat modeling, and disaster recovery tests.
- Communicate updates to stakeholders through concise briefs, dashboards, and internal FAQs.
- Pair Blue Team improvements with tabletop exercises to validate expectations.
