Describe the two basic security functions firewalls perform.
What will be an ideal response?
Firewalls perform two basic security functions:
· Packet filter - First and foremost, a firewall must be able to determine whether to allow or deny the passage of packets of digital information, based on established security policy rules.
· Application proxy - In some cases, a firewall may provide network services to users while shielding individual host computers. This is done by breaking the IP flow (i.e., the traffic into and out of the network) between the network being protected and the network outside.
