Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, insider threats represent a significant concern for government and business organizations alike. Over the last couple of years, the number of insider threat incidents increased by 47%, while the associated cost increased by 31%. In 2019, Desjardins, a Canadian bank, was a victim of a data breach caused by a malicious insider who exfiltrated confidential data of 4.2 million clients. During the same year, Capital One was also a victim of a data breach caused by an insider who stole the data of approximately 140 thousand credit cards. Thus, there is a pressing need for highly-effective and fully-automatic insider threat detection techniques to counter these rapidly increasing threats. Also, after detecting an insider threat security event, it is essential to get the full details on the entities causing it and to gain relevant insights into how to mitigate and prevent such events in the future. In this thesis, we propose an elaborated insider threat detection system leveraging user profiling and cyber-persona identification. We design and implement the system as a framework that employs a combination of supervised and unsupervised machine learning and deep learning techniques, which allow modelling the normal behaviour of the insiders passively by analyzing their network traffic. We can deploy the framework as part of online traffic monitoring solutions for insider profiling and cyber-persona identification as well as for detecting anomalous network behaviours. The different models employed are assessed using specific metrics such as Accuracy, F1 score, Recall and Precision. The conducted experimental evaluation indicates that the proposed framework is efficient, scalable, and suitable for near-real-time deployment scenarios.

Available in PDF, EPUB and Kindle. Book excerpt: Cyber attacks against companies and organizations can result in high impact losses that include damaged credibility, exposed vulnerability, and financial losses. Until the 21st century, insiders were often overlooked as suspects for these attacks. The 2010 CERT Cyber Security Watch Survey attributes 26 percent of cyber crimes to insiders. Numerous real insider attack scenarios suggest that during, or directly before the attack, the insider begins to behave abnormally. We introduce a method to detect abnormal behavior by profiling users. We utilize the k-means and kernel density estimation algorithms to learn a user's normal behavior and establish normal user profiles based on behavioral data. We then compare user behavior against the normal profiles to identify abnormal patterns of behavior.

Available in PDF, EPUB and Kindle. Book excerpt: Insider threat represents a major cyber-security challenge to companies, organizations, and government agencies. Harmful actions in insider threats are performed by authorized users in organizations. Due to the fact that an insider is authorized to access the organization's computer systems and has knowledge about the organization's security procedures, detecting insider threats is challenging. Many other challenges exist in this detection problem, including unbalanced data, limited ground truth, and possible user behaviour changes. This research proposes a comprehensive machine learning-based framework for insider threat detection, from data pre-processing, a combination of supervised and unsupervised learning, to deep analysis and meaningful result reporting. For the data pre-processing step, the framework introduces a data extraction approach allowing extraction of numerical feature vectors representing user activities from heterogeneous data, with different data granularity levels and temporal data representations, and enabling applications of machine learning. In the initial detection step of the framework, assume no available ground truth, unsupervised learning methods with different working principles and unsupervised ensembles are explored for anomaly detection to identify anomalous user behaviours that may indicate insider threats. Furthermore, the framework employs supervised and semi-supervised machine learning under limited ground truth availability and real-world conditions to maximize the effectiveness of limited training data and detect insider threats with high precision. Throughout the thesis, realistic evaluation and comprehensive result reporting are performed to facilitate understanding of the framework's performance under real-world conditions. Evaluation results on publicly available datasets show the effectiveness of the proposed approach. High insider threat detection rates are achieved at very low false positive rates. The robustness of the detection models is also demonstrated and comparisons with the state-of-the-art confirm the advantages of the approach.

Book excerpt: The purpose of this research is to investigate, design and implement a statistical analysis-based insider threat detection product deployable to resource-disadvantaged systems and provide organizations with a method for baselining the network profiles and host activities unique to their operational environments. Our system design seeks to alert the system and its operators to invest greater monitoring resources against hosts who exhibit threat characteristics of insider activity and prevent such activities from inflicting harm on the system and/or causing an information-loss event for the organization. This system provides an initial starting point for future work, implementing one means of detecting insider threat activities; this implementation results in best- and worst-case detection rates of 74% and 68.2%, respectively, against our test data. We believe our framework provides a reasonable starting point for future work and improvement.This compilation includes a reproduction of the 2019 Worldwide Threat Assessment of the U.S. Intelligence Community.Significant effort and expense have been spent protecting information systems from external malicious threats, but relatively little has been done to evaluate the actions of legitimate users to prevent them from engaging in malicious or otherwise damaging activity. As seen in the recent DoD leaks by Edward Snowden, Bradley Manning, and Reality Winner, the insider threat possesses significant destructive potential against national security, international relations, and global commerce interests. While external threat protection systems, like antivirus software, are established to be viable threat prevention means and are ubiquitous on modern information technology (IT) systems, detection and prevention systems focused on insider threats and are far less common. Previous work to improve insider threat detection and prevention includes efforts to apply existing frameworks and techniques to malicious activity detection, but they are disparate in their methods of classifying and assigning threat potential to the various user activity indicators. These differing means of describing malicious indicators and responding to threats are also often not applicable to the DoD due to the restrictions imposed by network authorization/validation processes and concerns unique to national security systems. We seek to alleviate this issue by producing a systems-agnostic solution capable of detecting insider activity within any organization's network without the need for integration or communications with any other external system.

Book excerpt: Insider threat detection is one of the most difficult challenges facing industry and the Intelligence Community (IC) today. This paper reviews and integrates several accepted psychological constructs into a behavioral model that can be adapted for practical use and suggests new tools to leverage this model to mitigate threats from insiders who may intentionally decide to harm their organization or our national security. The model of behaviors in this paper, derived from a body of research studies on malicious insiders, assumes that an initially loyal employee does not suddenly transform into a malicious insider. Certain personality traits may predispose an employee to acts of espionage, theft, violence, or destruction. These traits may be reinforced by environmental and organizational stressors. Less severe counterproductive work behaviors commonly occur before the decision to initiate a major damaging act. Clustering these behaviors into families may help define an "early warning system" and improve understanding of how individual characteristics and environmental factors may mitigate or intensify concerning behaviors.
