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