A Novel SIP Based Distributed Reflection Denial-of-Service Attack and an Effective Defense Mechanism

A Fuzzy Logic based Defense Mechanism against Distributed Denial of Service Attack in Cloud Computing Environment

Cloud defines a new age of computing solution that provides services to customers with its unique features of agility and multi-tenancy. As the critical resources are hosted at cloud provider’s end, security is a big challenge in cloud computing. If the cloud environment is compromised and attackers get the access of core data centers, the availability of the critical resources becomes a big co...

Distributed Denial of Service Defense Attack Tradeoff Analysis (DDOS-DATA)

Denial of Service Attack and Defense

In this chapter, we firstly review the short history of denial of service (DoS) and distributed denial of service (DDoS) attacks. We further explore the reasons why the current cyberspace is a heaven for cyber criminals, such as DDoS attackers. We present the challenges of the DDoS related research fields from various aspects, and discuss the possible research methods and strategies to serve th...

A Probabilistic Defense Mechanism Against Distributed Denial of Service Attacks

Distributed denial of service attacks form a prolific threat to any form of client-server computing, as used, for instance, by e-commerce businesses. The resources of standard servers are quickly consumed under such an attack, making them unavailable to legitimate users. We describe and analyze a defense mechanism for such servers. We prove that this mechanism favors benign users, making the se...

Detecting Denial of Service Message Flooding Attacks in SIP based Services

Increasing the popularity of SIP based services (VoIP, IPTV, IMS infrastructure) lead to concerns about its ‎security. The main signaling protocol of next generation networks and VoIP systems is Session Initiation Protocol ‎‎(SIP). Inherent vulnerabilities of SIP, misconfiguration of its related components and also its implementation ‎deficiencies cause some security concerns in SIP based infra...
