When you create a new Firewall policy, the policy includes several default rules. You can modify one or multiple rule components as needed.
The components of a firewall rule are as follows:
Customizing firewall rules
In the console, open a Firewall policy.
On the Firewall Policy page, click Rules.
On the Rules tab, in the Rules list, in the Enabled field, ensure that the box is checked to enable the rule; uncheck the box to disable the rule.
Symantec Endpoint Protection only processes the rules that you enable. All rules are enabled by default.
Double-click the Name field and type a unique name for the firewall rule.
Right-click the Action field and select the action that you want Symantec Endpoint Protection to take if the rule is triggered.
In the Application field, define an application.
In the Host field, specify a host trigger.
In addition to specifying a host trigger, you can also specify the traffic that is allowed to access your local subnet.
In the Service field, specify a network service trigger.
In the Log field, specify when you want Symantec Endpoint Protection to send an email message to you when this firewall rule is violated.
Right-click the Severity field and select the severity level for the rule violation.
In the Adapter column, specify an adapter trigger for the rule.
In the Time column, specify the time periods in which this rule is active.
Right-click the Screen Saver field and specify the state that the client computer's screen saver must be in for the rule to be active.
The Created At field is not editable. If the policy is shared, the term Shared appears. If the policy is not shared, the field shows the name of the group to which that the non-shared policy is assigned.
Right-click the Description field, click Edit, type an optional description for the rule, and then click OK.
If you are done with the configuration of the rule, click OK.
