Trend Micro Business Account can determine the clients that are allowed to access the administrator console, End User Console, and resources within Trend Micro Email Security by specifying a list of approved IP addresses. The Business Account can also specify the action to take on the access request from an unapproved IP address.
With this feature enabled:
Only administrator from the approved IP addresses can be authorized to log on to the administrator console (either through local account or SSO), verify their profiles, and complete API access.
API access aims to perform operations on resources within Trend Micro Email Security and synchronize user directories via REST APIs.
For more information, refer to the Trend Micro Email Security REST API Online Help and Directory Synchronization Tool User's Guide at http://docs.trendmicro.com/en-us/enterprise/trend-micro-email-security.aspx for details.
Only end users from the approved IP addresses can be authorized to log on to the End User Console (either through local account or SSO), activate their accounts, and perform digest inline actions.
For the access request from an unapproved IP address, Trend Micro Email Security can allow access without IP address check, allow access but record audit logs, or block access and record audit logs, depending on your access control settings.
The Logon Access Control screen includes the following tabs:
Access Control Settings: Displays the access control settings that you want to apply to the access requests from unapproved IP addresses.
Approved IP Addresses: Lists the IP addresses from which the access to Trend Micro Email Security are always allowed.
