Abstract

Networking provides the main infrastructure for different recent applications. These application are targets for different types of attack. In this paper a structured literature for different types of attacks has been proposed. It presents a survey of viruses, worms and bots. Latest network security technologies are investigated, the current situation and increasing demand for robust network security is analyzed; major portion of network attacks are launched using viruses, worm and bots. One of the most critical attacks are computer viruses. For security specialist it is vital to make difference any reproducing programs, which may not harm your system, and it closer forms. Different researches have been proposed to classify different aspects of metamorphic viruses. Worms is one of the most common propagation attacks over the internet. Two methods can be used by worm to propagate it: finding any vulnerable devices in the network and propagate using topological neighbors. Investigating the methods of worm propagation can provide a clearer vision on how worms propagate and how to defense and prevent such type of attacks. Last decade different mechanisms for detection and defensing have been proposed to deal with the bots attacks. Structures this knowledge can be very critical to better understand the bots behavior and its detection and defensive approaches.
