Monika Chauhan, Dr. Shishir Kumar, in International Journal of Information Technology and Management | IT & Management


Hostintrusion detection systems (HIDS) and network intrusion detection systems(NIDS) are methods of security management for computers and networks.In HIDS, anti-threat applications such as firewalls, antivirussoftware and spyware-detectionprograms are installed on every network computer that has two-way access to theoutside environment such as the Internet.In NIDS, anti-threat software is installed only at specific points suchas serversthat interface between the outside environment and the network segment to beprotected. All methods of intrusiondetection (ID) involve the gathering and analysis ofinformation from various areas within a computer or network to identifypossible threats posed by hackersand crackersinside or outside the organization. Host-based and network-based ID systemshave their respective advantages and limitations. The most effective protectionfor a proprietary network is provided by a combination of both technologies.
