What feature distinguishes a network intrusion prevention system (NIPS) from a network intrusion detection system (NIDS)?
a. A NIPS has sensors that monitor the traffic entering and leaving a firewall, and reports back to the central device for analysis.
b. A NIPS is located "in line" on the firewall itself.
c. A NIPS is designed to integrate with existing antivirus, antispyware, and firewalls that are installed on the local host computer.
d. A NIPS can use a protocol stack verification technique.
Answer: B
One of the major differences between a NIDS and a NIPS is its location. A NIDS has sensors that monitor the traffic entering and leaving a firewall, and reports back to the central device for analysis. A NIPS, on the other hand, would be located "in line" on the firewall itself. This can allow the NIPS to more quickly take action to block an attack.
