SFTP Admin Removed

The SFTP Admin account has been removed.

Related EMA Note

Note Regarding EMA

 If only keys (no password) are injected for the admin CLI user, then passwordLoginSupport is disabled by default. If standalone EMA access is required then this can be enabled and the generated password can be used to invoke EMA. Enabling  passwordLoginSupport is not needed in case EMA is accessed via EMS.

Related EMS Note

Since sftpadmin is removed, the EMS will use an alternate CLI account in its Administrator group (like admin) for SBC registration. There is no Cloud SBC impact because it uses emssftp. Refer to the Security and Security Best Practices sections in current EMS documentation.

 

Command Example

The following example uses the Account Management feature to accomplish the following actions:

  • Allows a locked account to unlock after five minutes
  • Enables SBC to defend against brute force attacks
  • Sets the number of consecutive failed attempts to "3"
% set system admin MYSBC accountManagement bruteForceAttack state enabled allowAutoUnlock enabled consecutiveFailedAttemptAllowed 3 unlockTime 300

% show system admin MYSBC accountManagement bruteForceAttack
state                           enabled;
consecutiveFailedAttemptAllowed 3;
allowAutoUnlock                 enabled;
