The Defense Security Service issued new rules for government contractors with facility security clearances that take effect on November 30, 2016. The changes are outlined in the National Industrial Security Program Operating Manual and require contractors to have an insider threat program plan, appoint an insider threat senior official, conduct annual self-inspections including insider threat vulnerability analysis, continue reporting relevant employee information, implement a system to identify careless classified information handling, provide insider threat training to employees, and monitor user activity on classified systems. All cleared contractors should review their policies and procedures with their facility security officer and legal counsel before the November 30 deadline.
