Firewall Policies

Firewall policies allow you to block or allow certain types of network traffic not specified in a policy exception. A policy also defines which firewall features get enabled or disabled. Assign a policy to one or multiple Firewall Profiles.

OfficeScan comes with a set of default policies, which you can modify or delete.

The default firewall policies are as follows:

Default firewall policies

Policy Name	Security Level	Client Settings	Exceptions	Recommended Use
All access	Low	Enable firewall	None	Use to allow clients unrestricted access to the network
Cisco Trust Agent for Cisco NAC	Low	Enable firewall	Allow incoming and outgoing UDP traffic through port 21862	Use when clients have a Cisco Trust Agent (CTA) installation
Communication Ports for Trend Micro Control Manager	Low	Enable firewall	Allow all incoming and outgoing TCP/UDP traffic through ports 80 and 10319	Use when clients have an MCP agent installation
ScanMail for Microsoft Exchange console	Low	Enable firewall	Allow all incoming and outgoing TCP traffic through port 16372	Use when clients need to access the ScanMail console
InterScan Messaging Security Suite (IMSS) console	Low	Enable firewall	Allow all incoming and outgoing TCP traffic through port 80	Use when clients need to access the IMSS console

Also create new policies if you have requirements not covered by any of the default policies.

All default and user-created firewall policies display on the firewall policy list on the Web console.
