Security Implementation through PCRE Signature over Cloud Network

Abstract

With invention of new tools and technologies, the attackers are designing new methods to evade present security models.One of such security models is Intrusion detections.Intrusion detection systems work on signature based analysis and anomaly based detection, which makes it vulnerable for new evasion techniques.This work describes the mitigation of evasion techniques by implementation of better PCRE based rules approach.IN this paper we are designing improved PCRE based rules to prevent evasion techniques on cloud systems.
