Unauthorized use of an account after credentials or tokens are compromised. Frequently follows credential stuffing, phishing, or session hijacking and results in fraud or data exposure.


Core objectives#

  • Establish shared definitions of Account Takeover for security, engineering, and leadership teams.
  • Connect Account Takeover activities to measurable risk reduction and resilience goals.
  • Provide onboarding notes so new team members can quickly understand how Account Takeover works here.

Implementation notes#

  • Identify the primary owner for Account Takeover, the data sources involved, and the systems affected.
  • Document the minimum viable process, tooling, and runbooks that keep Account Takeover healthy.
  • Map Account Takeover practices to standards such as ISO/IEC 27001, NIST CSF, or CIS Controls.

Operational signals#

  • Leading indicators: early warnings that Account Takeover might degrade (e.g., backlog growth, noisy alerts, or missed SLAs).
  • Lagging indicators: realized impact that shows Account Takeover failed or needs investment (e.g., incidents, audit findings).
  • Feedback loops: retrospectives and metrics reviews that tune Account Takeover continuously.

  • Align Account Takeover with defense-in-depth planning, threat modeling, and disaster recovery tests.
  • Communicate updates to stakeholders through concise briefs, dashboards, and internal FAQs.
  • Pair Account Takeover improvements with tabletop exercises to validate expectations.
