Application Control

1 Application Control

This module enables you to block and allow "applications", also named as "protocols". WFilter identifies each application by digital signature matching, even p2p applications can be completely blocked.

• Each client can be applied with multiple policies.
• Every policy can set "applied to clients" and "effective time".
• Besides the applied to "clients" and "time", detailed "app control policy" settings are described in below.

2 Rule Evaluation

• "Match all" means all rules will be evaluate. A visit will be blocked if any rule blocked it.
• "Match first" means only the first matched rule can block access. You can sort rules in this mode. For example, in "match first" mode, you can add a "block all" rule to all users. To allow a client, you can add an allow rule, and move this rule to top of the "block all".

3 Dynamic Filter

Every application(protocol) has three properties: "time-waisting", "bandwidth" and "risk". With dynamic filter, you can block applications by properties.

• When dynamic filter is enabled, you still can set blocking for each application.
• Every property has 1-5 five levels. For example, bandwidth(5-high) means this application occupies bandwidth in the highest level.

4 Deny and Allow

• You may check the applications list and set policy by clicking "edit".
• If "state" is "Automatic", this application will match the "dynamic filter" rule. "Deny" state applications will be blocked. "Allow" state applications will not be blocked.
• Applications with "-" properties won't be matched by "dynamic filter" rule.
• When "Priority" is enabled, this application won't be blocked by other rules or modules. For example, For example, "qq file transfer" is relayed by websites; if you block web surfing, "qq file transfer" will also be blocked unless "Priority" of "qq file transfer" is enabled.
