A firewall is your first line of defense against Internet security threats. It acts as the gatekeeper to keep hackers on the Internet from accessing data on your network. However, all firewalls are not the same. The key differences in firewalls are the amount and quality of information used to make decisions. The more information collected, the more security the firewall delivers.

Packet Filtering Firewalls
A packet filtering firewall simply examines the packet header and decides whether or not to let the packet proceed. Decisions are made in accordance with a set of rules or filters. The inability of packet filtering to dig deeper into the packet exposes your network to Denial of Service (DoS), IP Spoofing, and a host of prevalent Internet attacks. Most broadband routers include packet filtering firewalls along with IP networking features like NAT (Network Address Translation), and DHCP (Dynamic Host Configuration Protocol) to share broadband Internet connections. While these functions make it easy to connect a network to the Internet, they do little to improve the security of the connection since hackers can easily bypass NAT to gain access to your network.

Stateful Packet Inspection Firewalls
A stateful packet inspection firewall intercepts packets until it has enough to make a determination as to the state of the attempted connection before passing judgment. By maintaining a table of current connections and their most recent events, these firewalls are able to spot abnormal sequences inherent in hacker attacks. Stateful packet inspection is the most trusted firewall technology and is widely used in enterprise-class firewalls.
