Denial of Service (DoS) or Distributed Denial of Service (DDoS) is a powerful attack which prevents the system from providing services to its legitimate users. Several approaches exist to filter network-level attacks, but application-level attacks are harder to detect at the firewall. Filtering at application level can be computationally expensive and difficult to scale, while still creating bo...

The Internet of Things (IoT) ecosystem allows communication between billions devices worldwide that are collecting data autonomously. vast amount generated by these must be controlled totally securely. centralized solutions not capable responding to concerns due security challenges problems. Thus, the Average Packet Transmission RREQ (APT-RREQ) as an effective solution, has been employed overco...

ABSTRACT-PT Kodinglab Integrasi Indonesia's Virtual Private Server (VPS) product requires good quality standards, including security. The challenge that arises is still frequent disruptions to the protection of PT Kodinglab's VPS customers, where it difficult identify source attack. Network forensics in form dead and live using NIST method with stages collection, examination, Analysis, reportin...

­ Network intrusion detection sensors are usually built around low level models of network traffic. This means that their output is of a similarly low level and as a consequence, is difficult to analyze. Intrusion alert correlation is the task of automating some of this analysis by grouping related alerts together. Attack graphs provide an intuitive model for such analys...

Recent events have illustrated the Internet’s vulnerability to both denial of service (DoS) attacks and flash crowds in which links (or servers) in the network become severely congested. In both DoS attacks and flash crowds, the congestion is neither due to a single flow, nor due to a general increase in traffic, but to a well-defined subset of the traffic — an aggregate. This paper proposes ag...

MANETs are fast emerging as alternate network architecture to infrastructure networks. It is finding many applications and the constraints of processing power, memory, and bandwidth will be soon being overcome with the rapid improvement in the technologies. However the major concern which will remain is the security of the network. MANETs differ largely in the routing mechanism in the network l...
