  2. Background • Five years since the release of the first Insider Threat State of the Art Report • In reality, it’s been almost 7 years since the data was current. • While many exciting changes and innovations have taken place since that time in a number of detection areas, we’ve still been hit with Manning, Snowden, and others less visible. • Newer tools are now available for general and focused monitoring plus models have been validated for predicting personal behavior.

  3. Profiling • Personal Profiling • The precursors and threat indicators of potential malicious insider activities often associated with unhappiness, ethical or practical lifestyle issues • Activity Profiling • What an individual does in relation to their job function • Behavior Profiling • Specific activities that are suspicious in nature

  4. Personal Profiling • Developed from actual instances and case studies • These are often associated with ethical or practical lifestyle issues or developed by integrating employee data, including psychological or social data with audit data. • Profiling has been a primary focus of several research organizations over the past few years.

  5. Activity Profiling • People tend to perform their work in a particular way on a regular basis. • By segmenting job descriptions into unique areas of activity, graphic models can be developed. Normal Abnormal

  6. Behavior Profiling • Primarily IA detectable suspicious activities related to hacking, masquerading, compromised credentials, exfiltration, bad behavior, etc. • Use case examples compiled and published by NSA • Potentially detectable in near real time through audit data sequence analysis or other means • Biometric analysis of keyboard profiling or mouse movements • Multiple trusted remote login detection of compromised credentials

  7. In the SIGINT World • Protecting data isn’t always the problem. • Sometimes it’s the software and capabilities that need protecting. • In the tactical data collection world, is the user the same as the remote user who initially logged on? • What happens if a trusted user is logged on and the system is suddenly compromised by an untrusted insider with malicious intent?
