Example 52  Preventing Remote Allocation of the Audio Device

The No Users option in the Allocatable By section prevents remote users from hearing conversations around a remote system.

The security administrator configures the audio device in the Device Manager as follows:

Device Name: audio
For Allocations From: Trusted Path
Allocatable By: Authorized Users
Authorizations: solaris.device.allocate

Device Name: audio
For Allocations From: Non-Trusted Path
Allocatable By: No Users
