McAfee VirusScan On Delivery Email Scanner Properties must be configured to find unknown macro threats.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-6588	DTAM023	SV-56387r2_rule		Medium

Description
Email has become one of the most frequently used methods of spreading malware, through embedded HTML code and attachments. User awareness and training, warning users to not open suspicious emails or email attachments and not clicking on hyperlinks, etc. from unknown or known senders, will not fully protect from email-borne malware. Mass mailing worms are similar to an email-borne virus but is self-contained rather than infecting an existing file. Protecting from email-borne viruses and mass mailing worms by scanning email upon delivery mitigates the risk of infection via email.
