To apply these models effectively, organizations must classify data. Common classification structures include: Information that can be shared externally.
Ensure users are granted only the minimum level of access required to complete their daily job tasks.
These rules prevent information from flowing from a higher security level to a lower one, thereby preserving confidentiality. This model is built on mandatory access controls and a lattice structure of security levels.
