Potential Mitigations
| Phase | Strategy | Description | Effectiveness | Notes |
|---|
| Architecture and DesignOperation | | Very carefully manage the setting, management, and handling of
privileges. Explicitly manage trust zones in the software. | | |
| Architecture and Design | Separation of Privilege | Compartmentalize the system to have "safe" areas where trust
boundaries can be unambiguously drawn. Do not allow sensitive data to go
outside of the trust boundary and always be careful when interfacing
with a compartment outside of the safe area.Ensure that appropriate compartmentalization is built into the system
design and that the compartmentalization serves to allow for and further
reinforce privilege separation functionality. Architects and designers
should rely on the principle of least privilege to decide when it is
appropriate to use and to drop system privileges. | | |
