An enhancement of classification technique based on rough set theory for intrusion detection system application

An Intrusion Detection System (IDS) is capable to detect unauthorized intrusions into computer systems and networks by looking for signatures of known attacks or deviations of normal activity. However, accuracy performance is one of the issues in IDS application. Meanwhile, classification is one of...
