• A. Integrated Defense System
• B. Information Distribution System
• C. Intrusion Detection System
• D. Internet Data Service

Answer: (C)

In the context of network security, IDS stands for Intrusion Detection System. An Intrusion Detection System is a crucial component used to monitor network traffic for suspicious activity and potential threats. It analyzes incoming and outgoing traffic patterns to detect abnormal behavior, which may indicate a breach or cyberattack. The primary function of an IDS is to alert administrators to potential security incidents, allowing for a timely response to mitigate any damage.

An Intrusion Detection System can operate in various modes, including network-based and host-based, providing flexibility in deployment based on the security needs of an organization. By generating alerts based on predefined rules or learned behaviors, an IDS plays a key role in maintaining the integrity and protection of network resources.

This focus on detection, analysis, and alerting differentiates it from other options, which do not align with standard terminology used in network security. Understanding the function and significance of an Intrusion Detection System is essential for those involved in protecting networks from unauthorized access and other cyber threats.
