Understanding Insider Threats, Profiles, Technical and Behavioral Indicators

Recent global economic trends have led to corporate cost reductions, a shift from remote to hybrid work and the cost-of-living crisis. Coupled with regional conflicts these shifts have created an environment of uncertainty for businesses and their workforce. For many individuals, challenging financial and lifestyle changes may cause them to feel financially insecure at work and home.

These environments are sometimes optimal for insider threats which if ignored can cause reputational and fiscal damage to organizations. Insiders don’t have to find clever ways to penetrate the network as they already have legitimate access. They know where valuable data and systems reside and can gain access and circumvent controls effortlessly.

Security tools such as unified defense security information and event management (SIEM) and user and entity behavior analytics (UEBA) capabilities can detect abnormal behavior observed from potential insider activity indicating malicious intent. UEBA capabilities provide context to these behaviors and activities and can be correlated to insider threat models which are invaluable for understanding and addressing the full scope of an insider attack.

This ebook presents insider threats and risks, recaps the five insider threat profiles, and discusses the importance of technical and behavioral indicators when looking to mitigate insider threats.
