how to secure commands by disabling group access?

[Alborz]

Hi

I'm running a server using CentOS 5 x64

I want to disable access of groups to "bin" folder so they cannot execute commands.

[info: actually because of a bug in cPanel (the control panel I installed) Perl will give access to all hosting users to execute commands.]

so what i wanna do is to ban some groups on 'bin' folder, for example 'my_group1' and 'my_group2" cannot access bin but 'my_trusted_group' can access it.

how is it possible?

Not 100% sure what you are looking for here so....

If you are looking to deny all groups then you might just have to chmod the bin directory.

If you are looking to limit some groups then you might want to look at ACL.
