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.
