What does IDS stand for in network security?

The term IDS stands for Intrusion Detection System in the context of network security. An Intrusion Detection System is crucial for monitoring network traffic and identifying potential security breaches, such as unauthorized access or malicious activity.

An IDS works by analyzing patterns in data packets and comparing them against known threats or suspicious activities. This enables organizations to detect and respond to intrusions in real-time, which is vital for protecting sensitive data and maintaining the integrity of a network.

The other options do not accurately reflect the established terminology within the field of network security. While "Intrusion Defense System" might imply a system focused on defending against intrusions, it does not encompass the detection capabilities that are fundamental to an IDS. "Internal Data Security" is more focused on safeguarding data within an organization rather than monitoring for intrusions. Finally, "Information Defense Service" suggests a broader service but lacks the specific focus on detection that is critical to understanding an IDS.
