Encourage Reporting  Encourage employees to report  Provide confidential means of reporting  Staff holding security clearance are required to report adverse information, including potential threats  Trust your instincts, if you see something, say something!  It is better to report something that turns out to be nothing than to not report a serious security issue CENTRA TECHNOLOGY, INC. 12
    13. 13. Detecting the Insider Post incident investigations reveal family, friends, or coworkers notice a suspect’s indicators, but they fail to report concerns “Subjects often tell people close to them what they are doing, and sometimes even engage associates in the process. Former intimates (spouses, lovers, close friends – people with whom they spent a good deal of time) are a potentially important source of information in all investigations.”* *Source: Declassified Director of Central Intelligence Memorandum of 12 April 1990; Subject: Project Slammer Interim Report CENTRA TECHNOLOGY, INC. 13
