Cybersecurity: network security challenges

Overview

Cybersecurity is an enormously broad topic and covers a breadth of technologies and tools. From the first well-publicized international security incident on ARPANET in 1986, there has been a rapid evolution in the requirements of network security. Security threats have morphed from network level threats (intrusions and denial-of-service attacks) to much more sophisticated content based threats (viruses, worms, Trojans, spyware, etc...). As a result of this ever-increasing complexity, there is also a need for more sophisticated levels of intelligence to identify, analyse, and defend against cyber threats. This paper will provide a practical approach to actionable intelligence.
