High-speed packet content inspection and filtering devices rely on a fast multi-pattern matching algorithm which is used to detect predefined keywords or signatures in the packe...
Abstract—Deep packet inspection (DPI) is often used in network intrusion detection and prevention systems (NIDPS), where incoming packet payloads are compared against known attac...
Deep Payload Inspection systems like SNORT and BRO utilize regular expression for their rules due to their high expressibility and compactness. The SNORT IDS system uses the PCRE ...
