Which system finds security breaches and manages vulnerabilities?

• A. IDS
• B. Firewall
• C. Proxy Server
• D. Banner Guiding

Answer: (A)

An Intrusion Detection System monitors network and host activity to spot signs of breaches and policy violations. It analyzes traffic and events for known attack patterns or unusual behavior and raises alerts so security teams can respond quickly. This detection capability is what ties into vulnerability management: once a breach is detected, teams can investigate which vulnerabilities were exploited and prioritize remediation, patches, or compensating controls. The other options don’t fit as well because a firewall mainly blocks traffic rather than actively detecting breaches, a proxy server mediates and filters requests without focusing on breach detection, and banner guiding isn’t a recognized security solution.
