Managing the Policy

By default, InterScan™ Messaging Security Appliance (IMSA) includes a Global Antivirus rule to help protect your network from viruses and related Internet threats. Because an antivirus rule addresses the most critical and potentially damaging types of messages, you should always keep it in the first position on the rule list so IMSA can analyze traffic for virus content first.

The antivirus rule does not protect against spam. For the best protection against spam, configure a custom rule that includes spam in the scanning conditions, and activate the IP Filtering product (sold separately).

 

Types of Policies

You can create the following two (2) types of policies in IMSA to protect your network against various threats:
