An Edge-Based Blockchain-Enabled Framework for Preventing Insider Attacks in Internet of Things (IoT)
… targets of many different physical and cyber-attacks including insider attacks, thereby growing the overall security risks to the systems. This research, which focuses on addressing insider attacks on IoT, studies the likelihood of malicious insiders' activities compromising some of the …

Insider threat simulation and performance analysis of insider detection algorithms with role based models
Insider threat problems are widespread in industry today. They have resulted in huge losses to organizations. The security reports by leading organizations point out the fact that there have been many more insider attacks in recent years than any other form of attack. Detection of these insider …

An Architecture for Blockchain-based Collaborative Signature-based Intrusion Detection System
… to cope with the increasingly sophisticated cyberattacks. Despite the promising benefits such as expanded signature databases and alert data from multiple sites, trust management and consensus building remain as challenges for a CIDS to work effectively. The blockchain technology with built-in …

US Foreign Policy Towards National Movements: Impact of Joint Combat Operations, Affective Trust, and Identity
… NMs partners. Positive joint operations, free of insider attacks, are instrumental in building rational trust that evolves into affective trust over time. This trust elevates them to in-group status, fostering a shared identity. The affective bonds forged during these combat experiences shape …

Design and evaluation of information flow signature for secure computation of applications
… that the technique can provide 100% coverage for insider attacks that manifest as memory corruption and change the architectural state of the processor. Hence the IFS and CVR implementation offers a flexible, low-overhead, high-coverage method for ensuring reliable and secure computing.

Robust censorship-resistant communication
… proxies while preventing censors, posing as insiders, from discovering their addresses and blocking them. In this thesis, we study how to protect and/or design censorship circumvention systems to resist the insider attacks. Tor is one of the most popular censorship circumvention systems; it …

Insider Threat Reduction Model for the cloud environment
… the adoption of this paradigm. Specifically, the Insider threat is of greatest concern. In the traditional systems, insiders are regarded as current employees, former employees and any stakeholders that have access to the system. However, in the cloud computing environment the scope of insider …

Design and Verification of Privacy and User Re-authentication Systems
… chance for private data to be misused. Further, insider attacks can result in loss of valuable data. Hence there arises a strong need for continual, non-intrusive, quick user re-authentication. Previously, a number of studies have been conducted on authentication using behavioral attributes. …

Design and Analysis of QoS-Aware Key Management and Intrusion Detection Protocols for Secure Mobile Group Communications in Wireless Networks
… by rekeying operations to deal with outsider attacks. Instead of individual rekeying, i.e., performing a rekeying operation right after each group membership change event, these protocols perform batch rekeying periodically. We demonstrate that an optimal rekey interval exists that would …

A Framework for Secure Group Key Management
… material in the rekey message to guard against insider attacks. Our experiments show that the XORBP LKH approach substantially reduces a rekeying computation effort by more than 90%. Third, we propose two novel LKH batch rekeying protocols . The first protocol maintains a balanced LKH (B+-LKH) …
