Compliance Glossary

Intrusion Detection System (IDS) is a system or software that monitors the network traffic and system for signs of malicious activities and violation of any security policies. The IDS then issues alerts on the detection of any intrusions or security threats in real time so that database administrators or security analysts can take necessary actions to secure the system further. There are two types of IDS: host-based (installed on an individual’s system and server) and network-based (installed on a network). The IDS uses detection techniques, such as anomaly-based, signature-based, and behavior-based, to identify and report threats.
