What does IDS stand for in network security?

The term IDS in network security stands for Intrusion Detection System. An Intrusion Detection System is a crucial component of network security that monitors network traffic for suspicious activity and potential threats. It serves to alert administrators about unauthorized access, policy violations, or other malicious activities within a network.

IDS can be deployed in various forms, such as network-based or host-based systems, each serving to detect and analyze different types of intrusion. By providing a real-time monitoring system, it allows organizations to respond proactively to security incidents, ensuring the environment remains secure against potential harms.

While the other options presented might sound plausible, they do not accurately reflect the recognized term used in the field of network security. Terms like Internal Data Security and Intruder Defense Strategy, while they may relate to the broader subject of security, do not capture the specific function and aim of an IDS, which is fundamentally about detection and response to threats. Similarly, Internet Detection Source does not have any established meaning within the context of cybersecurity frameworks and practices.
