AS3 Personal Firewall is device designed to prevent outsiders from accessing your network. The unit serves as the single entry point to your network and evaluate all TCP connections requests as they are received comparing them with each rule in the policy. This is advanced easy to use software with ability to watch for all ports on your system without listening. Activity provides a real-time view of the open connections through the firewall. The rules editor is used to define a security policy where connections requests from unauthorized ip addresses and ports are rejected. The log viewer provides data connection notes that can be used for prosecuting the potential attackers. Use the rules editor to specify the destination and service for each rule with the required action. For example, if you don't want someone connecting to your network, you can bar his access by blocking connection request from his ip address or port number. On his end, he see a message that responds "Connection failed" or "Connection terminated". Once defined the firewall provides control of how the policy is distributed to all TCP connections through your network.
