Leaver Risk Use Case
A departing employee gathers, archives, forwards, or downloads business information before resignation, termination, retirement, or contract expiry.
Insider Threat Matrix™ Alignment
Referenced from the Insider Threat Matrix™ open framework.Why is this threat occurring?
How is the access enabled?
What staging occurs?
What execution paths?
What concealment techniques?
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 Personnel Assurance procedures. This use case directly involves the primary capability: Personnel Assurance. Additional related capability layers include: IAM, Data Protection, Monitoring, Analysis, Investigation.
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
- Deprovisioning leavers, movers, and joiners in silos across HR and IT, leaving credential gaps.
- Absence of monitoring baseline adjustments during high-risk lifecycle windows (e.g., performance reviews or notice periods).
- Uncoordinated monitoring of concurrent employment signs or unauthorized out-of-state work locations.
Mature Program Indicators
- Unified HR-triggered automated workflow that instantly adjusts access and reviews activity for departing employees.
- Regular proactive audits of concurrent payroll, BYOD access times, and geographic access anomalies.
- Close collaboration between HR, legal, and security during reorganizations or Reductions in Force (RIFs) to monitor key asset staging.
