Program Capability Alignment

Insider Risk Capability Framework™ (IRCF™) Mapping

This use case aligns to the Insider Risk Capability Framework™ (IRCF™) by mapping key capabilities required to govern, monitor, analyze, investigate, and control this threat pattern. It establishes responsible oversight and links back to canonical IAM procedures. This use case directly involves the primary capability: IAM. Additional related capability layers include: Personnel Assurance, Data Protection, Monitoring, Investigation, Oversight and Compliance.

Explore Canonical IAM Procedures

Prevention Control Themes

  • Least privilege and lifecycle access review
  • Data classification and data ownership
  • Acceptable-use expectations and role-based training
  • Legal, privacy, HR, and investigation governance
  • Monitoring, analysis, and case escalation aligned to approved use cases
  • Executive reporting that connects the scenario to exposure and risk decisions

High-Impact Telemetry Data Categories

  • UAM (User Activity Monitoring) endpoint logs and session screen captures
  • UEBA (User and Entity Behavior Analytics) behavioral anomaly alerts
  • DLP (Data Loss Prevention) transfer blockages and local copy events
  • IAM directory configuration alterations and authorization token tracking
  • PAM privileged session logs and root access tracking
  • Endpoint file-system audits and copy/zip command execution histories
  • Email proxy logs and outbound attachment volume metadata
  • Cloud storage API audit trails and shared folders exposure checks
  • Code repository download/cloning telemetry and API accesses
  • Collaboration platforms shared files and messaging channels access checks
  • Print queue logs and physical doc print audits
  • Physical security badge entries and workstation login correlations
  • HR case management updates and employee lifecycle milestones
  • Whistleblowing alerts and reports submission timestamps

Program Maturity Alignment Signals

Common Program Gaps

  • Allowing retired administrators or expired contractors to retain active system credentials.
  • Over-broad privilege assignments that exceed actual daily operational needs.
  • Unmonitored third-party or MSP delegated support connections bypassing local session logging.

Mature Program Indicators

  • Automated real-time deprovisioning immediately upon contract termination or HR status change.
  • Enforcing session-bound Just-In-Time (JIT) credentials for all administrative and cloud infrastructure activities.
  • Continuous analysis of privileged log integrity to detect unauthorized audit trail modifications or deletions.
