Computer Network is collection of computers and other hardware components interconnected by communication channels that allow sharing of information. Network security consists of the provisions and policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and Network-accessible resources. Network security involv...

The Internet of Things (IoT) plays a crucial role in various sectors such as automobiles and the logistic tracking medical field because it consists distributed nodes, servers, software for effective communication. Although this IoT paradigm has suffered from intrusion threats attacks that cause security privacy issues, existing detection techniques fail to maintain reliability against attacks....

Multiple schemes that utilize Probabilistic Packet Marking (PPM) have been proposed to deal with Distributed Denial of Service (DDoS) attacks by reconstructing their attack graphs and identifying the attack sources. By analyzing a set of PPM-based schemes, we show that past researchers have evaluated the schemes using disparate and often inadequate underlying topologies, which makes a side-by-s...

—One of the critical threat to internet security is Distributed Denial of Service (DDoS). This paper by the introduction of automated online attack classification and attack packet discarding helps to resolve the network security issue by certain level. The incoming packets are assigned scores based on the priority associated with the attributes and on comparison with probability distribution o...
