Cyber war and cyber-attack is an engaging review of the basic knowledge all up to date readers should have about cyber war and cyber-attacks before diving into more complex texts, as well as extra information for those already familiar with the topic. This work takes a look at general issues involving cyber vulnerability and our growing dependency on computers systems and networks. It goes beyond simple concepts such as hackers, hacktivism and espionage without neglecting them. It exposes the relevance of cyberdefence to both companies and ordinary users, giving especial attention to e-commerce platforms. At a time that many countries are employing strategies and money to prevent or minimize attacks as well as defend themselves against cyber threats this work pinpoints the key factors around the intentions behind attacks without minimizing their scale and variety. The jargon-free language and the current examples included help to set the discussion in the present day, while stressing important historical connections and pointing to how our strong network is at risk of becoming our weakest link.
The information infrastructure–comprising computers, embedded devices, networks and software systems–is vital to operations in every sector. Global business and industry, governments, and society itself, cannot function effectively if major components of the critical information infrastructure are degraded, disabled or destroyed.
This book contains a selection of 27 edited papers from the First Annual IFIP WG 11.10 International Conference on Critical Infrastructure Protection.
Wireless LANs can be found nearly everywhere today. Most mobile computers ship with built-in wireless LAN hardware by default and most other computers can be equipped with additional hardware. Because all data is transmitted wirelessly, extra security is needed in these networks. This was a concern to the creators of the IEEE 802.11 standard, who designed a simple protocol called WEP which stands for Wired Equivalent Privacy to protect such networks. Unfortunately, the WEP protocol has some serious design flaws and various attacks are possible against WEP protected networks. This book presents nearly all currently known attacks on the WEP protocol, including their theoretical background and their implementation. This book is intended for network operators, who want to learn more about wireless security, and also for cryptographers, who want to understand the theoretical background of these attacks.
Despite their popularity and wider deployment, IEEE 802.11 WLANs have been found to be vulnerable to security threats soon after their emergence requiring adoption of security measures. However, the introduced security measures didn't provide solutions for Denial of Service (DoS) attacks. This book characterizes the DoS attacks based on their ease of applicability and the degree of severity they introduce, and evaluates countermeasures for efficiency and effectiveness in defending against the attacks. Among various DoS attacks, Authentication Request Flooding (AuthRF) and Association Request Flooding (AssRF), which are practical and needing lesser effort to cause damage, were selected for study using OMNET++ simulation environment embedding INET Framework. Designs and models have been developed for the selected attacks and for two versions of defenses: countermeasure and enhanced countermeasures. The studied attacks, AuthRF and AssRF, required less effort and caused severe damage. Both versions of defenses, Countermeasure and Enhanced countermeasure, are effective although they incur delay.
