# restrictive sandboxes with limited responsibilities and thus limited

# permissions. Example: Audioserver is only responsible for controlling audio
|
|
|
|
|
# hardware and processing audio content. Cameraserver does the same for camera
|

|
|
|
# hardware/content. Etc.
|

|
|

# Media processing code is inherently risky and thus should have limited
|
|
|
|
|
# permissions and be isolated from the rest of the system and network.
