INTRUSION DETECTION AND PREVENTION SYSTEM: A COMPARATIVE STUDY

An intrusion Detection System (IDS) is a defensive- aggressive system to protect the information, verifying and responding to occurring attacks on computer systems and net- works. It provides an overview of the state of the art in intrusion detection research. Intrusion detection systems are software and/or hardware components that monitor computer systems and analyze events occurring in them for signs of intrusions. Due to the widespread diversity and complexity of computer infrastructures, it is difficult to provide a completely secure computer system. Therefore, there are numerous security systems and intrusion detection systems that address different aspects of computer security. It provides a taxonomy of IDS, along with brief descriptions. Second, a common architecture of intrusion detection prevention systems.
