Hello All,

We have almost 140 Linux Suse servers running in virtual environment, All the users are login to system as root account. There will be no check who is login and executing what.

My task to restrict the root account and promote the user named accounts and once the user login his account he can siwtch to root and perfrom the activities.

The above task i achieved by using sshd_conifig file changes of "Permirtrootlogin no" and "Allowusers" and its working fine.
but here is another problem came if tow users login their named account and switch to power users than again i can't track who is performed what

Kindly advise the industry best practice to implement the user security or at initial level of security what are steps i have to follow

Regards
Adnan

probably you can try sudo and sudoers, that can give you more restriction and more logging features. Also you can check the owner of the terminal, usually it will remain the original user (who opened that terminal - or logged in).

Definitely use sudo and DON'T give them all privs, it negates the the the whole soln.
Find out what cmds each user NEEDS (not wants!) and give them only those.

Why don't you switch on mandriva system, root account is separate on limited user account like on windows that you can use limit account for ordinary user.

I'll echo what pan64 and chrism01 suggested. It will take a lot of adjustment (especially for users who were used to do everything as root without thinking) but not allowing users to switch to root and limit the commands they may execute by using Sudo is the best way. On top of that SELinux audit service can track both user sessions and commands, albeit the latter in a limited fashion, so if you need a more complete user session audit trail please see Rootsh. *Note logging to a remote well-protected syslog server would be advisable.
