AIX audio devices must be group-owned by root, sys, bin, or system.

Without privileged group owners, audio devices will be vulnerable to being used as eaves-dropping devices by malicious users or intruders to possibly listen to conversations containing sensitive information.

Check the group owner of audio devices using commands:

# /usr/sbin/lsdev -C | grep -i audio aud0 Available USB Audio Device

# ls -lL /dev/*aud0 cr--r--r-- 1 root system 16, 0 Jan 24 07:25 aud0

If the group owner of an audio device is not "root", "sys", "bin", or "system", this is a finding.

Change the group owner of the audio device using command: # chgrp system <audio device>
