Enhanced device authentication

Enhanced device authentication
 ensures only trusted parties establish connections based on defined policies.

Operation

Enhanced device authentication
 adds the Subject Alternative Name (IP address) and may add DNS information unique for a device to its digital identity certificate. This method helps protect against identity spoofing.
You can customize the
enhanced device authentication
 to:
  • Receive notifications about devices that do not support
    enhanced device authentication
    .
  • Prohibit the policy deployment to devices that fail
    enhanced device authentication
    .
    IMPORTANT: It is recommended to prohibit the policy deployment to devices that fail
    enhanced device authentication
    .
To enable, disable, or configure
enhanced device authentication
, see Edit Global Settings.
TIP:
Enabling
enhanced device authentication
 involves the deployment of updates to all devices in the policy model. You can deploy the updates directly after enabling
enhanced device authentication
 or do that later.
