Check: GEN002320

Solaris 9 X86 STIG: GEN002320 (in version v1 r9)

Title

Audio devices must have mode 0660 or less permissive. (Cat II impact)

Discussion

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.

Check Content

Check the mode of audio devices. # ls -lL /dev/audio If the mode of audio devices are more permissive than 0660, this is a finding.

Fix Text

Change the mode of the audio device. # chmod -R 0660 /dev/audio
