Tools Restricting commands & access

Dear all,
I am administering a DC environment of over 100+ Solaris servers used by various teams including Databases.

Every user created on the node belonging to databases is assigned group staff(10) .

I want that all users belonging to staff should NOT be able to execute certain system commands like:

/usr/sbin/psrinfo -p


Also they should not be able to access certain predefined folders like /var/tmp .

How can this be achieved ?

do you know what is setuid and setguid ?

chmod o-x /usr/sbin/psrinfo /usr/sbin/prtdiag

This will deny execution rights for those two commands for everyone except for root and group that owns them.

And then be prepared to deal with a lot of broken applications, scripts, and utilities.

Restrict access to psrinfo and prtdiag?

As an alternative, you could use ACLs.

Note that Solaris by default uses NFSv4 ACLs which are a a bit different than standard POSIX (Linux) ones.

Solaris is using NFSv4 ACLs on ZFS filesystems. On UFS filesystems standard ACLs are used.

As far as I know, ZFS has been an unofficial standard for global zones since 2007-2008.

Of course the poster might be using Solaris 8, 9 or a really outdated release of S10.

Anyway... another example of why it's important to be specific about the OS version. Smilie
