Comparative Network Intrusion Detection technique DPI-AD for Regular Expression Detection in wireless Ad-hoc network

DPI-AD is a deep packet inspection technique for regular expression detection in wireless network. This technique design in the base of LaFA technique, which is use to detect regular expression of attacks on wireless network. DPI-AD used DDOS attack filter for detection of DOS attack. Regular expression detection module used to detect regular expression pattern for various attacks. LaFA uses pattern matching in simple detection and complex detection module which require more time for detection of attack pattern for regular expression attacks. The detection technique in LaFA detect cross site scripting (XSS) attack, where the SQL injection attack cannot be blocked. The DPI-AD recovers all its limitations and additionally it gives better detection results. For the testing purpose of this techniques Sql injection attack, XSS attack and DOS attack tests are done on DPI-AD. Other Regular expression techniques also discuss with compare to DPI-AD.
