deny access to certain users

[Guest_imported]

HI
I am using AIX 4.3.3 and i would like to know if it is possible to deny access to certain users from going into a directory and not to have permission to run some AIX commands. I only want it for specific users not everyone.

Thank you in advance.

Access Control Lists

Access control is composed of protected information resources that specify
who can be granted access to such resources. The operating system allows for
need-to-know or discretionary security. The owner of an information
resource can grant other users read or write access rights for that resource.
A user who is granted access rights to a resource can transfer those rights
to other users. This security allows for user-controlled information flow in
the system; the owner of an information resource defines the access permissions
to the object.

Users have user-based access only to the objects they own. Typically, users
receive either the group permissions or the default permissions for a resource.
The major task in administering access control is to define the group
memberships of users, because these memberships determine the users'
access rights to the files they do not own.

There is also regular permission for group that can be used....
