It is an urgent, imminent and present danger that we have to focus on the traditional terrorists, who are transforming ICT into the modern attacking tools that can devastate the metropolitan areas with the deconstruction of critical infrastructures via the computer network using state-of-the-art hacking and cracking technologies. The cyber terrorists could inflict catastrophic loss or damage on...

Cyber security is an important aspect of National Security and the safekeeping of a Nation's constituency and resources.

Cyber attacks have significantly increased over the last few years, where the attackers are highly skilled, more organized and supported by other powerful actors to devise attacks towards specific targets. To aid the development of a strategic plan to defend against emerging attacks, we present a high-level taxonomy along with a cyber defense model to address the interaction and relationships b...
