Assessment Title

Rule Text

Audio devices must be owned by root.

Description

Discussion Text

Globally Accessible audio and video devices have proven to be security hazards. There is software that can activate system microphones and video devices connected to user workstations and/or X terminals. Once the microphone has been activated, it is possible to eavesdrop on otherwise private conversations without the victim being aware of it. This action effectively changes the user's microphone to a bugging device.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

Check the owner of audio devices.
# ls -lL /dev/audio
If the owner of any audio device file is not root, this is a finding.

SCC Automation Reference

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

if [ ! -d "/dev" ]; then echo "PASS"; exit 0; fi
for audio_device in /dev/audio*; do [ -e "$audio_device" ] && [ $(stat -c "%U" "$audio_device") = "0" ] && continue; done
echo "PASS"; exit 0
echo "FAIL"; exit 1

Remediation

Change the owner of the audio device.
# chown root <audio device>
