GENERAL DUTIES:
  • Design, implement, and maintain insider threat detection signatures tailored to organization data, user behavior, and access patterns.
  • Translate threat intelligence and incident learnings into practical, testable signatures; continuously refine signals to reduce false positives.
  • Collaborate with Insider Threat Program (ITP) stakeholders to align signatures with policies, acceptable use, and incident response playbooks.
  • Validate and test signatures in controlled environments, document detection logic, data sources, and tuning parameters.
  • Monitor performance and effectiveness of signatures; propose and implement improvements.
  • Contribute to threat modeling exercises by mapping insider risk scenarios to measurable signals.
  • Maintain versioned signature libraries, track changes and rollback plans.
  • Participate in incident response, providing signature-based evidence and analytics to support investigations.
  • Ensure signatures comply with privacy, legal, and data protection requirements.
  • Regulatory Adherence: Ensure that all insider threat detection activities comply with relevant regulations, such as CNSS, ICDs, and industry-specific standards.
  • Audits and Reviews: Participate in internal and external audits, providing evidence of compliance and effectiveness of insider threat triggers.
  • Incident Investigation: Assist in the investigation of incidents related to insider threats, providing insights derived from triggers and alert analysis.
  • Root Cause Analysis: Conduct root cause analysis to identify underlying issues and recommend corrective actions to prevent future occurrences.
  • Remediation: Support the implementation of remediation measures based on the findings of incident investigations.
  • Regular Reporting: Generate regular reports on the performance and effectiveness of insider threat triggers, highlighting key trends and insights.
  • Metrics Development: Develop and track key performance indicators (KPIs) to measure the success of insider threat detection efforts.

REQUIRED QUALIFICATIONS:
  • 8 years of experience in DoD/IC insider threat programs developing and testing signatures and rules to detect anomalous user and entity behaviors and validating those detections against real or simulated insider-risk scenarios.
  • Demonstrated application of ICS 500-27 and CNSSD 504 requirements in the design and operation of insider threat capabilities.
  • Proven program building experience, advanced detection strategies (including behavior analytics), and enterprise-level governance of insider threat detection and response activities.
  • Degree Requirements Masters Degree in related field or an additional 6 years of experience
  • Certification Requirements: Must be DoD 8570 IAT Level III Certified
  • Highly Desired: Certified Counter Insider Threat Professional (CCITPF/CCITPA)

CLEARANCE:
