When protecting an organization’s IT systems, which of the following is normally the next line of
defense after the network firewall has been compromised?

A.
Personal firewall

B.
Antivirus programs

C.
Intrusion detection system (IDS)

D.
Virtual local area network (VLAN) configuration

Explanation:
An intrusion detection system (IDS) would be the next line of defense after the firewall. It would

personal firewalls and VI_AN configurations would be later in the line of defense.
