Intrusion Detection Systems

Intrusion detection systems is program designed for detection and identifying of malicious activity on a host or malicious activities within a computer network. Network-based intrusion detection systems check for live data, host-based intrusion detection systems examine the log files on the system.

 

Types Of Intrusion Detection Systems:

1. Host Intrusion Detection Systems (HIDS)

2. Network Intrusion Detection Systems (NIDS)

 

Both Network-based intrusion detection systems and host-based intrusion detection systems examine system records and activities. In Host-Based Intrusion Detection systems, most auditors usually look at log, event records and records in files. However, Network-based intrusion detection systems search for and examines packet data communicated within a networks.

 

Conclusion:

Both HIDS and NIDS implementation is necessary for a network. It is advisable to implement HIDS before NIDS because each and every computers must be examined before moving further on examining the network in which computers are connected.
