The IT security of automotive systems is an evolving area of research. To analyse the current situation and the potentially growing tendency of arising threats we performed several practical tests on recent automotive technology. With a focus on automotive systems based on CAN bus technology, this article summarises the results of four selected tests performed on the control systems for the win...

Addressing security vulnerabilities and system intrusions can represent a significant administrative overhead in current computer systems. Although technologies exist for both vulnerability scanning and for intrusion detection, the problems typically require some form of human intervention before they can be rectified. Evidence suggests that, in many cases, this can lead to omissions or oversig...

Intrusion Detection & Prevention Systems generally aims at detecting / preventing attacks against Information systems and networks. The basic task of IDPS is to monitor network & system traffic for any malicious packets/patterns and hence to prevent any unwarranted incidents which leads the systems to insecure state. The monitoring is done by checking each packet for its validity against the si...

Over the recent years, IP and email spoofing gained much importance for security concerns due to the current changes in manipulating the system performance in different online environments. Intrusion Detection System (IDS) has been used to secure these environments for sharing their data over network and host based IDS approaches. However, the rapid growth of intrusion events over Internet and ...

identification and analysis of farmers’ vulnerability associated with their risk aversion degree is one of the necessary requirements for planning and reducing impacts of drought in iran. so, this study was investigated three risk vulnerability parameters (economic, social and technical) among wheat farmers categorized in accordance with their risk aversion degree in the mashhad county (iran) b...

Security vulnerabilities remain present in many web applications despite the improving knowledge base on vulnerabilities. Attackers can exploit such security vulnerabilities to extract critical data from web applications and their users. Many dynamic security vulnerability scanners exist that try to automatically find such security vulnerabilities. We studied the adoption of these tools and fou...

The size and complexity of software systems is growing, increasing the number of bugs. Many of these bugs constitute security vulnerabilities. Most common of these bugs is the buffer overflow vulnerability. In this paper we implement a testbed of 20 different buffer overflow attacks, and use it to compare four publicly available tools for dynamic intrusion prevention aiming to stop buffer overf...

Wireless Mesh Networks (WMNs) are considered as a promising solution for offering low-cost access to broadband services. However, one of the main challenges in the design of these networks is their vulnerability to security attacks. In this paper, we analyze the fundamental security challenges and constraints of these networks, classify several possible attacks and survey several intrusion prev...

Intrusion detection systems continue to be a promising security technology. The arguably biggest problem with today’s intrusion detection systems is the sheer number of alerts they produce for events that are regarded as benign or non-critical by system administrators. A plethora of more and less complex solutions has been proposed to filter the relevant (i.e., correct) alerts that signature ba...

Research in the field of computer and network science demands for tools and methodology to test their security effectively. Intrusion Detection System is used to perform the same with a fact that an intruder’s behavior will be noticeably different from that of a legitimate user and would exploit security vulnerabilities. Proposed here is a novel intrusion detection approach with the application...
