What isintrusion detection

Protecting your network and system from malicious activities and policy breaches is crucial in today’s digital age. An intrusion detection system can help you with that.

Simply put, an intrusion detection system is a hardware or software program that monitors your network or system for any unusual activities or security policy violations. It alerts the administrator or records the activity centrally using a security information and event management (SIEM) system.

There are two types of intrusion detection systems: signature-based and anomaly-based. Signature-based systems use pre-determined patterns to detect known threats, while anomaly-based systems analyze incoming traffic and identify unusual behavior that may indicate a threat.

The two most commonly used categories of intrusion detection systems are network intrusion detection systems (NIDS) and host-based intrusion detection systems (HIDS). NIDS, as the name suggests, monitors network traffic, while HIDS monitors activity on individual hosts or devices. For example, a HIDS may monitor crucial operating system files, while a NIDS examines incoming network traffic.

Investing in an intrusion detection system can help protect your network and system from potential threats and breaches.
