About the OfficeScan Firewall
The OfficeScan firewall protects clients and servers on the network using stateful
inspection, high performance network virus scanning, and elimination. Through the
central management console, you can create rules to filter connections by IP address,
port number, or protocol, and then apply the rules to different groups of users.
The OfficeScan firewall includes the following key features and benefits:
Traffic Filtering
The OfficeScan firewall filters all incoming and outgoing traffic, providing the ability to
block certain types of traffic based on the following criteria:
• Direction (inbound/outbound)
• Protocol (TCP/UDP/ICMP)
• Destination ports
• Source and destination computers
Scanning for Network Viruses
The OfficeScan firewall also examines each packet for network viruses. For details, see
Network Virus on page 5-4.
Customizable Profiles and Policies
The OfficeScan firewall gives you the ability to configure policies to block or allow
specified types of network traffic. Assign a policy to one or more profiles, which you can
then deploy to specified OfficeScan clients. This provides a highly customized method
of organizing and configuring firewall settings for clients.
Stateful Inspection
The OfficeScan firewall is a stateful inspection firewall; it monitors all connections to
the client and remembers all connection states. It can identify specific conditions in any
connection, predict what actions should follow, and detect disruptions in a normal
connection. Therefore, effective use of the firewall not only involves creating profiles
and policies, but also analyzing connections and filtering packets that pass through the
firewall.
