What is the main focus of intrusion detection in network security?

Intrusion detection primarily revolves around identifying and reporting signs of unauthorized access to network resources. The main goal is to monitor network traffic and system activities for suspicious behavior that could indicate a breach or potential threat. With effective intrusion detection, organizations can quickly respond to security incidents, minimizing damage and increasing the chances of mitigation before a situation escalates.

For instance, intrusion detection systems (IDS) analyze data packets for known patterns of attacks or anomalies that deviate from normal operation. This capability is crucial for maintaining the integrity, confidentiality, and availability of information within a network. By focusing on detecting unauthorized access, organizations enhance their ability to secure sensitive data, further protecting against potential security breaches.
