A Review on Intrusion Detection System and its Techniques

Technology development has brought so many threats and hazards at a very high rate in the recent years. The development of application, software tools and its usage in all the fields has brought the awareness about the security. Many mechanisms are used as the security tool such as firewalls, antivirus, spam filters and anti-malware for the security purposes to protect their system and network. Intrusion detection system is a very powerful security system to detect any abnormal or unauthorised access to the system and to the network. This paper is about the study of the importance of intrusion detection, classification of intrusion detection system (IDS), its datasets and usage in various applications. The intrusion detection system has got many developments through its datasets, new technologies and methods but as the technologies increases, the threats of attacking the system and data breaches also increases, so in order to overcome this problem a hybrid framework for the intrusion detection has to be developed to detect the intrusions from the intruder.
