2. Advanced Rules: Advanced rules provide more granular control over network traffic by allowing administrators to define complex criteria based on various factors, such as application signatures, user groups, and schedules.

Creating and Managing Firewall Rules

To create a new firewall rule in Forcepoint Firewall:

1. Open the Forcepoint Firewall management console.
2. Navigate to the ‘Firewall’ section.
3. Click on the ‘Rules’ tab.
4. Click on the ‘Add Rule’ button.
5. Select the rule type (Standard or Advanced) and configure the rule parameters.
6. Click on the ‘Save’ button to apply the rule.

Firewall rules can be modified or deleted as needed to adapt to changing network requirements or security threats.

Creating and Managing Security Policies

Security policies in Forcepoint Firewall are collections of firewall rules that are applied to specific network segments or groups of users. Policies provide a convenient way to enforce consistent security policies across different parts of the network.

To create a new security policy:

1. Open the Forcepoint Firewall management console.
2. Navigate to the ‘Policies’ section.
3. Click on the ‘Add Policy’ button.
