Careless insider—an innocent pawn who unknowingly exposes the system to outside threats. This is the most common type of insider threat, resulting from mistakes, such as leaving a device exposed or falling victim to a scam. For example, an employee who intends no harm may click on an insec...
As these examples show, insider threat-based data misuse by employees within an organization is widespread and can occur anywhere. Though an organization may have data loss prevention (DLP) tools in place, it is possible for these tools to miss the user and their activity before and after each...
Although alternative proposals incorporate a psychosocial angle by utilising correlations between real-world insider cases and their emotional state, personality type or predispositions, they also pose several limitations. In order to mitigate the challenges, this work builds on such profiling methodologies...
Insider threat detection has attracted significant attentions over the last decade, where various insider threat detection approaches have been proposed (Eldardiry et al., 2013; Le and Zincir-Heywood, 2018; Rashid et al., 2016; Salem et al., 2008; Sanzgiri and Dasgupta, 2016; Tuor et al.,...
A number of researchers in the field of mobileauthenticationhave proposed passive or userbiometric featuresas the primary form ofdevice authentication. Examples of suchauthentication schemesinclude fingerprints, iris scanners and location detection. For example,Xu et al. (2014)studied the feasibility of...
Insider threat intrusion detection systems can be classified into two categories: (i) generic intrusion detection systems and (ii) intrusion detction systems designed specifically to address data imbalances. A summary of these systems is presented in Table 1. Generic insider threat intrusion detection ...
We’ll start off simple, and gradually build to increasingly more complex, more futuristic examples of how this technology might well turn against us, forcing us to solve problems we’d never considered before. Prompt Injection Which takes us to late last year, as ChatGPT took the world by ...
Examples include .exe, .scr, and .zip files, among others. Always question why someone would send such files unless explicitly expected as part of ongoing communications. Employ attachment scanning tools: Several online tools are designed explicitly for analyzing potentially harmful attachments without ...
In some examples, the malicious script can erase the console. Therefore, the security testing system can detect the absence of normal script logging, which suggests the presence of malicious code. Alternatively or in addition, a malicious script can be designed to be able to redefine a console ...
