The recent evolution of Internet to new paradigms such as network function virtualization and software defined networking poses new relevant challenges to the detection of Botnet attacks, calling for innovative approaches. In this work we propose a detection mechanism based on an Artificial Neural Net classifier trained by available data sets collected in conventional networks. We apply such de...

A botnet is a network of compromised computers, termed bots that are used for malicious purposes. When a computer becomes compromised typically through a drive-by download, that has embedded malicious software, that computer becomes a part of a botnet. A bot typically runs hidden and uses a covert channel to communicate with its command and control server. Botnets are controlled through protoco...

A recent emerging trend in the underground economy is malware dissemination as a service. Complex botnet infrastructures are developed to spread and install malware for third-party customers. In this research work, a botnet forensic investigation model is proposed to investigate and analyze large-scale botnets. The proposed investigation model is applied to a real-world law-enforcement investig...

Botnets have become one of the most serious security threats to the traditional Internet world. Although the mobile botnets have not yet caused major outbreaks worldwide in cellular network, but most of the traditional botnet experience can be transferred to mobile botnet on mobile devices, so mobile botnet may evolve faster since techniques are already explored. From the theoretical work of so...

BotNets are major threat of the current Internet. It is widespread malware and it arises commonly in today‟s cyber crime, which results in serious threats to our network. The compromised computer is infected by viruses, worms, or it has become a target of network attacks only when operational state of a network component is shifted from normal state to abnormal state. Thus, prevention and detec...

As if fueled by its own fire, curiosity and speculation regarding botnet sizes abounds. Among researchers, in the press, and in the classroom—the questions regarding the widespread effect of botnets seem never-ending: what are they? how many are there? what are they used for? Yet, time and time again, one lingering question remains: how big are today’s botnets? We hear widely diverging answers....

Botnets have evolved to incorporate peer-to-peer communication for the purpose of better hiding the administrative source of the botnet. Current botnet detection mechanisms identify network traffic patterns at strategic locations within a network such as the gateway. As detection techniques improve, botnet design will continue to evolve to evade detection; thus, it is advantageous to identify p...

Since the number of compromised computers, or botnet, continues to grow, the cyber security problem has become increasingly important and challenging to both academic researchers and industry practitioners. A respect to combat botnet propagation is to understand the attacker’s behaviors based on the whole operation of a system that can be modeled with population models used in epidemiological s...

Internet users have been attacked by widespread email viruses earlier, but now scenario has been changed. Now attackers are no more interested to just attract media attention by infecting a large number of computers on the network; in fact, their interest has been shifted to compromising and controlling the infected computers for their personal profits. This new attack trend brings the concept ...
