Abstract:
In recent years, dynamic user verification has become one of the basic pillars for insider threat detection. From these threats, the research presented in this paper focuses on masquerader attacks, a category of insiders characterized by being intentionally conducted by persons outside the organization that somehow were able to impersonate legitimate users. Consequently, it is assumed that masqueraders are unaware of the protected environment within the targeted organization, so it is expected that they move in a more erratic manner than legitimate users along the compromised systems.

Abstract:
Masquerade attacks pose a significant challenge in cybersecurity, as intruders mimic legitimate user behavior to evade detection. In dynamic, data-intensive environments, traditional intrusion detection systems often struggle to provide both timely and interpretable results, limiting their usefulness for effective Cyber Situational Awareness (CSA). This article presents a clustering-based approach for detecting masquerade attacks using OK-Means—a variant of K-Means optimized for faster convergence—combined with a nearest neighbor classifier and noise reduction techniques.

Abstract:
In computer security, masquerade detection is a special type of intrusion detection problem. Effective and early intrusion detection is a crucial factor for computer security. Although considerable work has been focused on masquerade detection for more than a decade, achieving a high level of accuracy and a comparatively low false alarm rate is still a big challenge. In this paper, we present a comprehensive empirical study in the area of anomaly-based masquerade detection using three deep learning models, namely, Deep Neural Networks (DNN), Long Short-Term Memory Recurrent Neural Networks (LS

Masquerading animals have evolved striking visual resemblances to inanimate objects.

User profiles are important in many applications since they record highly user-specific information - profiles are basically built to record information about users or for users to share experiences with each other. This research extends previous research on re-authenticating users with their user profiles. This research focuses on the potential to add psychometric user characteristics into the user model so as to be able to detect unauthorized users who may be masquerading as a genuine user

Abstract:
Independent wireless communication is possible in a "mobile ad hoc network" regardless of any predefined administrative or physical framework. The comprehensive enhancement of services for these networks depends on protecting their interactions. The Sybil attack creates numerous counterfeit identities to disrupt the system's remote functionalities. Implementing a security plan necessitates the establishment of a trust model that delineates the confidence relationships among entities. The trust structure in mobile ad hoc network security has been extensively researched. Mobile ad hoc networks a
