NIST 800-171 Control 3.2.3: Insider Threat Awareness Training
Insider threats represent one of the most damaging security risks to organizations handling controlled unclassified information. NIST 800-171 3.2.3 requires you to train employees on recognizing suspicious behavior and reporting procedures. This control bridges awareness and accountability to prevent internal compromise.
What this means
Control 3.2.3 mandates that your organization deliver security awareness training specifically focused on identifying and reporting potential insider threats. This training must educate employees on recognizing indicators of malicious insider activity—including unauthorized access attempts, data exfiltration, policy violations, and behavioral red flags—and provide clear channels for confidential reporting. The goal is to transform your workforce into a defense layer that actively monitors and reports suspicious activity before it causes harm.
How to comply
- 1.Develop insider threat awareness curriculum covering threat indicators, reporting procedures, and non-retaliation policies
- 2.Deliver training to all personnel with access to CUI, with annual refresher cycles
- 3.Document attendance and completion records for audit evidence
- 4.Establish clear, confidential reporting channels (hotlines, email, management escalation)
- 5.Define what constitutes reportable behavior with concrete examples
- 6.Train managers to recognize and handle insider threat reports appropriately
- 7.Communicate case outcomes (when appropriate) to reinforce the value of reporting
Evidence auditors look for
- Training curriculum outline and materials addressing insider threat recognition
- Attendance logs and training completion records by employee and date
- Non-retaliation policy statements integrated into training or security policies
- Documentation of reporting channels (hotline numbers, email addresses, procedures)
- Threat indicator reference guides or awareness posters
- Manager training materials on handling insider threat reports
- Annual training scheduling and reminder communications
- Incident logs showing reports received and follow-up actions taken
