The Overview of Intrusion Detection System Methods and Techniques

System and network security is still the main concern for researchers and system administrators. Different types of software and hardware devices are used to eliminate the dangers of hacking, attacks, breakthroughs, and cybercrimes. With the increasing creativity of attackers, the development of a complete security system is impossible. In network security, no other tools are available as Intrusion Detection System (IDS), which has the abil- ity to locate and identify malicious activities by examining network traffic. It provides administrators with reliable network monitoring and control. In this paper, we give an overview of the Intrusion Detection System principles, types, methods, and detection techniques.
