Configuring malware inspection
Updated: February 1, 2011
Applies To: Forefront Threat Management Gateway (TMG)
Using Forefront TMG, you can inspect outbound HTTP traffic for malware (such as, worms, viruses, and spyware). By enabling malware inspection on Web access rules, the Malware Inspection Filter scans Web pages and files that were requested by client computers, and either cleans harmful HTTP content or blocks it from entering the corpnet.
Outbound inspection refers to HTTP requests that originate from clients on networks protected by Forefront TMG.
Malware inspection can be configured on both a global level for all the members of an array, and a per-access rule level. For general information about malware inspection, see Planning to protect against malicious web content.
