Operating Systems AIX Best practices for sugroups for root ? backdoor user access ? Post 303021725 by MichaelFelt on Wednesday 15th of August 2018 01:28:08 PM

Actually, another process would be to use what is know as a dual password account.

I'll over simplify for now.

a) have a privileged account - i.e., let's say to suroot. This account is either added to sudoers, or setup using RBAC to be more powerful. "Audit" is also setup to monitor this accounts activity.

b) have two "key accounts", each of these have it's own password - which could be shared or coming from the vault. Each of these account has /bin/false as shell.

c) when access to "suroot" is needed TWO people (one from a "group" or vault access to key-1 password, and another with access to key-2 password)
* start by entering "suroot" as username at login (e.g., console) prompt. System will prompt for password from key-1; then system will prompt for password of account key-2 - and the login will complete with "suroot" the active user.

Note: if key-1 or key-2 try to login it will always "fail" because the shell is /bin/false (even root cannot "su" to that userid).

Hope this helps.
