Procedure

  1. Go to Administration → Other Settings → Logon Access Control.
  2. On the Access Control Settings tab, select whether to allow access to Trend Micro Email Security from unapproved IP addresses.
    • Administrator Console: Select an action (Bypass, Allow and log, and Block and log) to take on the access request to the Trend Micro Email Security administrator console from an unapproved IP address. The default value is Bypass.
      • Bypass: The request bypasses access control check. Trend Micro Email Security allows the access without verifying the client's IP address.
      • Allow and log: Trend Micro Email Security allows the access but records audit logs.
      • Block and log: Trend Micro Email Security blocks the access and records audit logs.
      This setting also applies when administrators attempt to verify their profiles from an unapproved IP address.
    • End User Console: Select an action (Bypass, Allow and log, and Block and log) to take on the access request to the Trend Micro Email Security End User Console from an unapproved IP address. The default value is Bypass.
      This setting also applies when end users attempt to activate their accounts from an unapproved IP address.
    • API Access: Select an action (Bypass, Allow and log, and Block and log) to take on the access request to Trend Micro Email Security through REST APIs from an unapproved IP address. The default value is Bypass.
    Note
    Note
    IP-based access control is enabled if you select Allow and log or Block and log for any of the drop-down lists. In this case, at least one approved IP address must be configured on the Approved IP Addresses tab; otherwise, IP-based access control will not take effect.
  3. Optionally select Also apply to digest inline action.
    Selecting this check box applies the same setting configured for End User Console to digest inline actions.
  4. Optionally specify the email addresses to receive alerts on blocked or logged access.
    1. Type one or more email addresses as the alert recipients in the Email Address field.
      Use semicolons (;) to separate email addresses. There is no need to add a space after a semicolon.
    2. Specify the maximum number of alerts that can be sent within 24 hours.
  5. Click Save.
