What is deep packet analysis and how does it work?

Deep packet analysis is a network methodology that is particularly useful in firewalls. The use of deep packet inspection technology has increased in recent years because it can be used as part of intrusion detection systems (IDSs) and intrusion prevention systems (IPSs). Firewalls traditionally block access to a network.
