Which of the following potentially blocks hacking attempts?

A. intrusion detection system

B. Honeypot system

C. Intrusion prevention system

D. Network security scanner

Explanation:

An intrusion prevention system (IPS) is deployed as an in-line device that can detect and block hacking attempts. An intrusion detection system (IDS) normally is deployed in sniffing mode and can detect intrusion attempts, but cannot effectively stop them. A honeypot solution traps the intruders to explore a simulated target. A network security scanner scans for the vulnerabilities, but it will not stop the intrusion.
