The identification of the exact path that packets are routed on in the network is quite a challenge. This paper presents a novel, efficient traceback strategy named Tracemax in context of a defense system against distributed denial of service (DDoS) attacks. A single packet can be directly traced over many more hops than the current existing techniques allow. In combination with a defense system it...
Named-Data Networking (NDN) is a promising architecture for future Internet. Its design, however, can be misused to perform a new DDoS attack known as the Interest Flooding Attack (IFA). In IFA, the attacker issues non-satisfiable interest packets, aiming to drop legitimate interest packets by overwhelming pending interest tables in NDN routers. Prior defence mechanisms are not highly effective, harm...
Hybrid Peer-to-Peer streaming systems combine the advantages of an efficient push-based with a more resilient pull-based system to deliver video streams over the Internet. In this manner, hybrid systems offer low latency and an increased robustness to failures and node churn. However, current hybrid systems is vulnerable to misbehaving nodes and deliberate attacks. By taking central positions in the...
Distributed denial of service attacks aim at making a given computational resource unavailable to users. A substantial portion of commercial Intrusion Detection Systems operates only with detection techniques based on rules for the recognition of pre-established behavioral patterns (called signatures) that can be used to identify these types of attacks. However, the characteristics of these attacks...
