What does IDS stand for in network security?

In network security, IDS stands for Intrusion Detection System. This term refers to a device or software application designed to monitor network or system activities for malicious actions or policy violations. An Intrusion Detection System examines network traffic for signs of unauthorized access attempts, attacks, or other suspicious behavior and can alert administrators or take action to mitigate these threats.

An Intrusion Detection System operates by analyzing network packets, inspecting logs, and identifying patterns that indicate a potential threat, such as port scans or unusual traffic spikes. The importance of an IDS lies in its ability to provide visibility into the security posture of a network, enabling organizations to respond promptly to potential security breaches.

For clarity, the other options like "Internet Defense System," "Intranet Data Security," and "Information Distribution Service" reflect terminology that does not accurately encapsulate the purpose or function of an IDS, leading to confusion regarding its role within network security.
