Insider Threat Mitigation Guidance STI Graduate Student Research
by Balaji Balakrishnan - October 9, 2015
Insider threats are complex and require planning to create multi-year mitigation strategies. Each organization should tailor its approach to meet its unique needs. The goal of this paper is to provide relevant best practices, policies, frameworks and tools available for implementing a comprehensive insider threat mitigation program. Security practitioners can use this paper as a reference and customize their mitigation plans according to their organizations' goals. The first section provides reference frameworks for implementing an insider threat mitigation program with the Intelligence and National Security Alliance (INSA) Insider Threat roadmap, Carnegie Mellon University's Computer Emergency Response Team (CERT) insider threat best practices, CERT insider threat program components, National Institute of Standards and Technology (NIST) Cybersecurity Framework, and other relevant guidance. This section provides an implementation case study of an insider threat mitigation program for an hypothetical organization. The second section of this paper will present example use cases on implementing operational insider threat detection indicators by using a risk scoring methodology and Splunk. A single event might not be considered anomalous, whereas a combination of events assigned a high-risk score by the methodology might be considered anomalous and require further review. A risk scoring method can assign a risk score for each user/identity for each anomalous event. These risk scores are aggregated daily to identify username/identity pairs associated with a high risk score. Further investigation can determine if any insider threat activity was involved. This section explains how to implement a statistical model using standard deviation to find anomalous insider threat events. The goal is to provide implementation examples of different use cases using a risk scoring methodology to implement insider threat monitoring.

Most of the computer security white papers in the Reading Room have been written by students seeking GIAC certification to fulfill part of their certification requirements and are provided by SANS as a resource to benefit the security community at large. SANS attempts to ensure the accuracy of information, but papers are published "as is". Errors or inconsistencies may exist or may be introduced over time as material becomes dated.
