What is a reason for an organization to deploy a personal firewall?
A . To protect endpoints such as desktops from malicious activity.
B . To protect one virtual network segment from another.
C . To determine whether a host meets minimum security posture requirements.
D . To create a separate, non-persistent virtual environment that can be destroyed after a session.
E . To protect the network from DoS and syn-flood attacks.

Answer: A

Explanation:

The term personal firewall typically applies to basic software that can control Layer 3 and Layer 4 access to client machines. HIPS provides several features that offer more robust security than a traditional personal firewall, such as host intrusion prevention and protection against spyware, viruses, worms, Trojans, and other types of malware.
