Composite signature-based analysis refers to a method of intrusion detection where multiple packets are analyzed to detect an attack signature. Unlike single-packet analysis, which may only require one packet to identify an attack, composite signature-based analysis looks for patterns across several packets to determine whether an attack is underway. This method is particularly useful for detecting complex attacks that cannot be identified by a single packet’s header or payload alone.
References: The concept of composite signature-based analysis is part of the broader network defense strategy that includes protecting, detecting, responding, and predicting network security incidents. It aligns with the Certified Network Defender (CND) program’s focus on understanding network traffic signatures and analysis as part of designing network security policies and incident response plans123.
