What it means
MAC is designed for environments where information sensitivity and authorized clearance must constrain access even when a resource owner would prefer to share it.
Why it matters
The model provides strong centralized enforcement but requires disciplined labeling, administration, and handling processes.
Practical focus
- Define labels and clearances consistently
- Control who can assign and change labels
- Test information flows across levels
- Train users on handling requirements
Common mistakes
- Confusing MAC with device hardware addresses
- Applying labels without reliable classification
- Creating exceptions that bypass the central policy
