The best firewall for Windows will protect against incoming
threats and be able to block outgoing threats from malware that has
successfully infiltrated your system. A good firewall will know when it is
under attack because it will constantly scan the computer’s ports to detect
threats. A firewall applies rules to the packets it sees in order to enforce
polices. It knows when to allow or reject traffic. When it detects illegal
traffic, it applies filters so that only traffic that it defines as legal makes
it through.
