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