What does IDS stand for in security?

• A. Intrusion Detection System
• B. Internet Data Service
• C. Internal Defense System
• D. Inbound Data Security

Answer: (A)

IDS stands for Intrusion Detection System. It watches network or host activity to spot unauthorized access or policy violations and then generates alerts for investigators to respond. It can be deployed on the network to monitor traffic or on individual machines to track local activity. Unlike a firewall, which blocks traffic, an IDS typically focuses on detection and reporting (though some systems can trigger automated responses). The other terms listed don’t reflect the standard security meaning of IDS, so they aren’t used in this context.
