Exploiting the vulnerabilities of LTE Wi-Fi sharing devices

Evaluating encryption algorithms for sensitive data using different storage devices

Sensitive data need to be protected from being stolen and read by unauthorized persons regardless of whether the data are stored in hard drives, flash memory, laptops, desktops, and other storage devices. In an enterprise environment where sensitive data is stored on storage devices, such as financial or military data, encryption is used in the sto...

Detecting Sybil attack in mobile wireless sensor networks using observer nodes

RESEARCH QUESTIONS: What lightweight, scalable algorithm can be developed to detect the Sybil nodes in MWSNs? Then, I broke it to more detailed questions as follows:  How many observer nodes would be enough for a wireless sensor network to detect the Sybil attack?  How often should an observer node collect information about neighbouring nodes?  ...

Estimating the risk of fraud against e-services

Industry is continuously developing, deploying, and maintaining e-services to transform traditional offerings. While protection of traditional services is well understood, their digital transformation often is vulnerable to known and new attacks. These vulnerabilities open the door for fraudsters to exploit the weaknesses of the new systems and ass...

Analysis of L4 DoS/DDoS attacks and mitigation techniques for DNS reflection attack

Cybersecurity is a very important area that needs to be worked on and improved. Day by day technology becomes closer to human life in many ways. In recent years, especially after the emergence of IoT and cloud computing, technology has started to control a big part of our assets. These assets could be data medical assets, financial assets, etc. For...

SecTrust : a trust and recommendation system for Peer-2-Peer networks

The concept of Trust has been applied in many information systems such as e-commerce, social networks and smart grid networks. It is currently getting attention on the Internet of Things. The fundamental concept in Trust, is the ability of a user to evaluate its neighbour, or a recommended neighbour with the hope of being able to trust that user. I...

Social engineering attacks and countermeasures in the New Zealand banking system : advancing a user-reflective mitigatio...

Social engineering attacks are possibly one of the most dangerous forms of security and privacy attacks since they are technically oriented to psychological manipulation and have been growing in frequency with no end in sight. This research study assessed the major aspects and underlying concepts of social engineering attacks and their influence in...

A trust-based defence scheme for mitigating blackhole and selective forwarding attacks in the RPL routing protocol

The routing protocol for low-power and lossy networks (RPL) has gained prominence as the standard IoT routing protocol. However, it faces like many other routing protocols diverse attacks. Many studies have been proposed to secure the RPL protocol, and simulation studies have been put forward as the main research method, while testbed experiments, ...

Defence mechanisms evaluation against RA flood attacks for Linux Victim Node

This research evaluates the performance of different defence mechanisms used in IPv6 networks to protect against router advertisement (RA) flood attacks that rely in ICMPv6 Router Advertisement messages to flood the network. Three types of RA flood attacks are considered: the default RA flood attack, RA flood attack with fragmented packets and RA f...
