[V3] What is Personal Firewall?
The personal firewall, powered by a suite of V3 for Windows, is a feature which uses rules to allow or block network access by programs and other entities.
You can add or delete the rules in V3’s Settings > [Personal Firewall]. You must click on [Apply] for the changes made to the settings to be saved.
Profile
The Profile is a feature which sets how to handle the connections not defined by network or program rules.
How to Handle
| Rule Name | Description |
| Allow all | Allows all network connections not registered by rules. |
| Block all | Blocks all network connections not registered by rules. |
| Prompt me to choose an action |
Notifies the user if any network connections not registered by rules occur. The user can view the notification to either allow or block the connection. |
|
Allow trusted programs automatically (Default) |
Depending on whether ‘Verify digital signature’ and ‘Enable ASD Reputation System’ checkboxes are selected or not, automatic connections are granted to trust programs. The user is notified if the connection is not trusted. |
| Select automatically | Follows the same rule as ‘Allow trusted programs automatically’, but blocks all untrusted connections without notifying the user. |
Other Options
| Option | Description |
| Check the hash value |
The program rules operate based on the path, but if this option is enabled, the rules will also check the hash value as well as the path. Therefore, a connection will be recognized as a new connection if a file was changed due to updates or other events. |
| Block port scan attack | A feature which prevents any external access to the internal systems, except for the ports that have been allowed by the systems to scan incoming port. |
Network Rules
Use Network Rules to allow or block connections from specific ports or IP.
You can click [Rule List] of Network Rules to add or modify the network rules.
Since the rules at the top of the list have higher priority than the ones below, the priority must be defined whenever a new rule is added.
The network rules have a higher priority than the program rules.
Program Rules
Use Program Rules to allow or block connections for each program. These rules can be automatically added based on the active profile.
Program rules are grouped by manufacturers, and are categorized into ‘Others’ if there is no information about the manufacturer.
The program rules have a lower priority than the network rules.
