Emulation of SUDO using Solaris RBAC

Reference sudo vs RBAC Emulation of SUDO using Solaris RBAC ACLs usage is roles Profile Shells Humor Etc

Role-based access control allows system administrators to delegate the administrative control of parts of the system to users. Users can be given the ability to run commands with additional privilege in two ways. Either by assigning a profile directly to the user, in which case no additional authentication is required. Or by creating a role. It can also be used to build restrictive environments for users by removing their ability to run commands they would normally be allowed to.

Why use RBAC vs sudo (for Solaris)

(Note this may not apply to all OpenSolaris distributions)

Why use sudo rather than RBAC

What about sudo & privileges ?

Having sudo be privilege aware would be great for OpenSolaris as well. This would probably be done by adding new keywords to the sudoers grammar so that you can specify the privileges that the command should run with. It would be very cool if someone could implement this and contribute it back to the main sudo branch.

RBAC Best Practices for OpenSolaris developers

The following best practice documents for using RBAC in developing other parts of OpenSolaris can be found in the ARC community:

RBAC TODO List

The following is a list of mini projects or RFEs that we know we need to implement in the OpenSolaris RBAC framework to get parity with sudo or to fill a customer need.

Please help us out by implementing one of these:

Ability to set and clear any environment variable for a specific entry in exec_attr(4).

Restrict which arguments to a command get the additional privilege, For example run passwd(1) but only with a user name not with any of the password aging options.

For all of the RBAC databases that make up a profile definition and assignment of it to a user (execattr, profattr, userattr) control which hosts it is valid on using netgroups. The currently unused "qualifier" field in userattr(4) is intended for this as is one of the reserved fields in prof_attr(4).

History of RBAC in Solaris

The main stream Solaris first got RBAC in Solaris 8. In Solaris 9 new profiles were added but no new core functionality from the framework. In Solaris 10 RBAC was integrated with least privilege, SMF and SMC.

Trusted Solaris (now replaced by Trusted Extensions) had an RBAC system in all of its releases going back to the SunOS 4.1.3 based versions. The implementation was slightly different but the basic concepts are the same.
