What is a firewall?

 

The firewall is a filter that protects your PC, preventing unauthorized intruders from entering. It is also an effective tool for allowing you to use the Internet securely.

The firewall doesn't just filter inbound and outbound connections when the computer connects to the Internet, it also monitors connections between your computer and other network computers with which you can share files, folders, printers and other resources.

 

Firewall in user mode

In user mode, every time a program tries to connect to the Internet from your computer, or when an external program or user tries to connect to your PC, will ask you if you want to allow the connection. It will do this through pop-up messages that let you authorize or deny connections and configure other related aspects.

If, however, the firewall detects that a safe process (goodware) is attempting to connect from the computer to the Internet, it will allow the connection without displaying any warning messages, and will automatically create a rule to always allow this type of connection from that moment on. If it were an inbound connection, however, the firewall would display a warning and ask the user whether to allow it or not.

Click the Firewall section to enable/disable and configure the firewall protection.

 

Firewall in administrator mode

In administrator mode, the firewall is configured by an administrator from the Web console. The local user won't be asked to allor or block any connections, as all connections will be governed by the rules defined by the administrator.

In administrator mode, the local user can't enable/disable or configure the firewall protection.
