Data and IP Exposure Cluster

Data Exfiltration by Insiders Use Case

A user with legitimate access gathers sensitive files, stages them locally or remotely, and moves them through an approved channel used in an unapproved way, such as email, cloud storage, removable media, screenshots, messaging, or an AI platform history.

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 Data Protection procedures. This use case directly involves the primary capability: Data Protection. Additional related capability layers include: Monitoring, Analysis, Investigation, IAM, Oversight and Compliance, Risk Management and Reporting.

Explore Canonical Data Protection 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

  • Treating all file transfers as isolated security alerts, causing high analyst fatigue.
  • Relying solely on signature-based DLP rules, which are easily bypassed by renaming files or archiving.
  • Unmonitored printing or screenshot capture of highly sensitive code, designs, or trade secrets.

Mature Program Indicators

  • Correlating unexpected data hoarding behaviors with active workforce leaver triggers or HR cases.
  • Continuous automated discovery (DSPM) of shadow repositories containing proprietary IP.
  • Enforcing zero-trust segregation of duties restricting massive downloads on critical repositories.
