The protocols used to communicate with readers must be secured because the communication with a reader can be listened to and manipulated by an attacker.

What you should know

Some communication protocols are more secure than others. Follow the recommendations to ensure your reader connections are secure:
  • Avoid using the Wiegand protocol
  • Use the OSDP v2 protocol with the secure channel mode enabled
NOTE: The reader must be online for the connection settings to be taken into account in the security score.


  1. From the Config Tool home page, open the Access control task, and click the Roles and units view.
  2. From the entity browser, select an access control unit, and click the Hardware tab.
  3. Click the tabs for your integrations, and change the reader settings follow the recommendations, as required:
    Reader type
    The connection is not secure if the reader is Wiegand or Clock and data.
    For OSDP readers, the connection is not secure if the Reader type is set to Raw card reader and the Connection settings are set to either Unencrypted or Encrypted with a Default key.
  4. Click Apply.
