On this page, you can adjust the firewall security settings to limit external connections according to the environment in which the computer is being used.
Three security levels are defined:
- Home/low risk zone – suitable when using your computer as part of a home/private network. If this setting is selected, the firewall will allow all communication with the network.
- Work/medium risk zone – suitable for when your computer is connected to a wider public network, including direct connections to the internet. This is the default setting and if selected, the firewall will allow communication in and out only if allowed by the “Application Rules”. If no rule has been created, you will be asked to confirm whether or not communication with a particular application should be allowed.
- Public/high risk zone – suitable when using your computer to connect to a public network and where you want to ensure the maximum level of security. This is the most secure setting and if selected, no incoming communication will be allowed, effectively making your computer completely invisible to others.
You can adjust the level of security by either clicking on the relevant icon, or by clicking on the orange slider and moving it to the left or right while holding the mouse button down.
On this page, you can also turn off the firewall completely, either permanently or for a specified period of time by clicking the Stop button and selecting the required option. Click Start to turn it on again.
