Software free firewall

Both types of firewall work by filtering web traffic. They use three methods of doing this: packet filtering stateless , stateful, and application layer filtering.

A packet filtering firewall will inspect all traffic flowing through it and will allow or deny that traffic depending on what the packet header contains. Packet filtering firewalls are called stateless firewalls because they do not know what is sending the traffic. Some will allow users to set rules to further refine the level of freedom or protection the firewall offers. Stateful firewalls record all connections and watch them as they progress.

That way they know whether a particular program has a legitimate connection to the internet, whether it should be transmitting traffic, what kind of traffic and whether all that matches to the current state of that program. Stateful firewalls are complicated but very good at what they do.

Application layer filtering firewalls adds to the stateful feature by also analyzing the data being transmitted. It matches the program with the application and checks its rules to see whether that connection is allowed or not. It then sends or drops traffic according to those rules. There are other types of firewall such as circuit-level gateways and multilayered inspection firewalls but these are enterprise-level. Not really relevant to home users. Most free firewall software uses packet filtering.

This is a good level of protection for small networks or home users. It does not allow forensic investigation or content filtering but combined with a hardware firewall within a router, offers plenty enough protection for most uses.
