Since Business Email Compromise (BEC) scams target high profile users such as company executives, Trend Micro Email Security allows you to add high profile users who are likely to be impersonated for detection and classification.
Specify the email display names of the high profile users who might be frequently forged. Trend Micro Email Security will check incoming email messages claimed to be sent from those users and apply fraud checking criteria to identify forged messages. Trend Micro Email Security enables you to take actions on either the analyzed or probable BEC attacks.
The specified high profile users are applicable to all BEC policies of your domains as the global settings.
Synchronize users from Directory: select this option to synchronize users from your directory.
Click Select Groups to select a user group that you want to synchronize.
A maximum of 100 users can be synchronized from one or multiple directory groups. If there are more than 100 users, Trend Micro Email Security sorts all users alphanumerically in ascending order and applies BEC policies only to the first 100 users.
The Directory Synchronization Tool is required to synchronize user information from the directory server. For details about installing and updating the tool, see the Directory Synchronization Tool User's Guide. To download the tool and the guide, do the following:
Go to Administration > Directory Management.
On the Directory Synchronize tab, find the tool and guide under Downloads.
If you select Microsoft AD Global Catalog for synchronization in the Directory Synchronization Tool, make sure the givenName, initials and sn attributes have been replicated. By default, these attributes are not replicated to the global catalog server by Microsoft. If they are not replicated, use the Active Directory Schema snap-in in the Microsoft Management Console for replication.
