For more protection against unauthorized access to a computer, you can use:
A
Only one software firewall
B
Two or more software firewalls
C
Only one hardware firewall
D
A combination of one software firewall and a hardware firewall
Correct Option:
D
Explanation
Using network-level protection from a hardware firewall together with host-level protection from a software firewall provides layered security. Running several software firewalls simultaneously can instead create conflicts, so combining different defensive layers is the better approach.
