m0-53    Wed May 10 00:06:41 2023   ALERT      Security                                EVT-DDBOOST-00001: Default authentication mode for DDBoost clients does not provide over-the-wire encryption.

------   ------------------------   --------   -----------------   -----------------   -------------------------------------------------------------------------------------------------------------

Cause

If DD Boost encryption strength is set to none in the previous DDOS release, and DDOS is upgraded to 7.10.1.10, 7.7.5.20, or 7.12, or a later version, then a security alert is raised to remind the user to enable encryption.

Command to check current encryption strength:

ddboost option show global-encryption-strength

Resolution

Steps using CLI:

  1. Clear the alert manually: 
    alerts clear alert-id <alert-id-list>
  2. Set the global-encryption-strength to medium or high:

    Syntax:

    ddboost option set global-authentication-mode none global-encryption-strength {medium | high}
  3. Reset global authentication mode and global encryption strength to none:
ddboost option set global-authentication-mode none global-encryption-strength none

Steps using UI:

  1. Log in to the Data Domain System Manager (UI).
  2. Go to Protocols.
  3. Go to DD Boost.
  4. Click More Tasks in the upper right corner.
  5. Select Set Option.
  6. Under Security, select encryption strength to medium or high.
  7. Click OK.
  8. Go to Health.
  9. Go to Alert.
  10. Select the alert and click Clear.

To reset Global Authentication Mode back to 'none':

  1. Go to Protocols.
  2. Go to DD Boost.
  3. Click Configure before Global Authentication Mode.
  4. Select none and click OK. This resets the global authentication mode and global encryption strength to none.
Note: Keeping the current global-encryption setting may trigger a reminder alert "Default authentication mode for DD Boost clients does not provide over-the-wire encryption," but DD Boost operation successfully continues. Setting global-encryption to medium or high may result in a drop in Boost I/O performance. If over-the-wire encryption is required, change global-encryption to medium or high.

 

Note: If using Avamar Integrated Data Protection Appliance with Session Security Settings enabled, it is safe to disregard this alert. Avamar is already encrypting the data and there is no necessity to use DD Boost encryption. Use the below command to disregard the alert from the Data Domain.
