Real-World Work Combating Insider Threats

We at the CERT Insider Threat Center are proud to announce the release of the fifth edition of the Common Sense Guide to Mitigating Insider Threats (CSG). This edition of our best practice guide is based on our significantly expanded corpus of more than 1,000 insider threat incidents and our continued research and analysis. This edition covers new technologies and new threats.

Our researchers have spent over a decade at the CERT Division exploring, developing, and analyzing operational resilience as a way to not just manage risks, but to achieve mission assurance. Resilience has been codified in our CERT-Resilience Management Model (CERT-RMM), which is a maturity framework of best practices across security, business continuity, and information technology operations focused on an organization's critical assets.

Each year, the CERT Division of the SEI collaborates with CSO Magazine to develop a State of Cybercrime report. These reports are based on surveys of approximately 400 organizations across the country, ranging in size from less than 100 employees to over 10,000.

In this blog post, I describe sentiment analysis and discuss its use in the area of insider threat. Sentiment analysis, often referred to as opinion mining, refers to the application of natural language processing (NLP), computational linguistics, and text analytics to identify and extract subjective information in source materials (Wikipedia).
