Cyber attacks are continuing to hamper working of Internet services despite increased use of network security systems such as firewalls and Intrusion protection systems (IPS). Recent Distributed Denial of Service (DDoS) attacks on Dec 8, 2010 by Wikileak supporters on Visa and Master Card websites made headlines on prime news channels all over the world. Another famous DDoS attacks on Independe...

mod_security (an open source intrusion detection and prevention engine for to the Internet, securing your systems against attackers must be a high priority. An Intrusion Detection System against DDOS for MANETs attacks MANET also contains wireless sensor nodes, these highly secure IDS to detect attacks. 2. knowledge from the packet flow and packet details to detect DDOS attacks.

Distributed denial of service (DDoS) is a structured network attack coming from various sources and fused to form a large packet stream. DDoS packet stream pattern behaves as normal packet stream pattern and very difficult to distinguish between DDoS and normal packet stream. Network packet classification is one of the network defense system in order to avoid DDoS attacks. Artificial Neural Net...

Denial of service attacks, viruses and worms are common tools for malicious adversarial behaviour in networks. Experience shows that over the last few years several of these techniques have probably been used by governments to impair the Internet communications of various entities, and we can expect that these and other information warfare tools will be used increasingly as part of hostile beha...

DDoS attacks are highly distributed, well coordinated, offensive assaults on services, hosts, and infrastructure of the Internet. Effective defensive countermeasures to DDoS attacks will require equally sophisticated, well coordinated, monitoring, analysis, and response. The Cossack project is developing an architecture to explore such coordination using multicast, annotated topology informatio...

Di antara berbagai jenis serangan di bidang Teknologi Informasi, DDOS adalah salah satu ancamanterbesar bagi situs internet dan menimbulkan risiko yang menghancurkan keamanan sistem komputer, terutamakarena potensi dampaknya. Oleh karena itu mengapa penelitian ini berkembang pesat, dengan parapeneliti berfokus pada cara-cara baru untuk mengatasi deteksi pencegahan intrusi. Machine learningdan A...

DDoS attacks on the World Wide Web in broad-spectrum and predominantly in modern cloud computing has become a noticeable issue for researchers in academia and industry related to the field of computer sciences. DDoS attacks are cool to provoke but their uncovering is a very challenging and dingy task and therefore, an eye-catching weapon for hackers. Hence DDoS torrents do not have familiar app...

Distributed denial of service (DDoS) attack is a continuous critical threat to the Internet. Derived from the low layers, new application-layer-based DDoS attacks utilizing legitimate HTTP requests to overwhelm victim resources are more undetectable. The case may be more serious when such attacks mimic or occur during the flash crowd event of a popular Website. Focusing on the detection for suc...

Malicious intruders may launch as many invalid requests as possible without establishing a server connection to bring server service to a standstill. This is called a denial-of-service (DoS) or distributed DoS (DDoS) attack. Until now, there has been no complete solution to resisting a DoS/DDoS attack. Therefore, it is an important network security issue to reduce the impact of a DoS/DDoS attac...

Distributed Denial-of-Service (DDoS) attacks are a major problem in the Internet today. In one form of a DDoS attack, a large number of compromised hosts send unwanted traffic to the victim, thus exhausting the victim’s resources and preventing it from serving its legitimate clients. One of the main mechanisms that have been proposed to deal with DDoS is filtering, which allows routers to selec...
