IDS stands for which of the following?

• A. Intrusion Detection System
• B. Internet DNS System
• C. Identity Data Security
• D. Intelligent Detection Server

Answer: (A)

IDS stands for Intrusion Detection System, a security tool that monitors networks or hosts for suspicious activity, policy violations, or potential attacks and raises alerts for security teams. The name directly describes its job: detecting intrusions. There are network-based IDSs that inspect traffic across a network and host-based IDSs that watch events on a specific machine. They may use signature-based detection to spot known attack patterns or anomaly-based detection to flag unusual behavior. This combination of monitoring and detection is why this is the best fit. The other options don’t reflect the standard meaning. “Internet DNS System” isn’t a recognized expansion, since DNS stands for Domain Name System, not intrusion detection. “Identity Data Security” describes a broader concept rather than a specific security mechanism. “Intelligent Detection Server” could sound plausible but isn’t the established term used in practice for IDS.
