Impact analysis of faults and attacks in large-scale networks

An agent-based framework for the impact analysis of faults and attacks in large-scale networks is discussed. The framework is used to discover attack points and to examine the behavior of critical network components during an attack or system fault. The two common types of attacks are server attacks such as TCP SYN, and ICMP flood, and routing attacks, such as distributed denial-of-service (DDoS) attacks. In network attacks, attackers overwhelm the target system with a continuous flood of traffic designed to consume all system resources. The framework analyze the impact of multiple failures on overall system behavior and identify critical resources and vulnerabilities.
