- Confidentiality is the principle that objects are not disclosed to unauthorized subjects.
- Integrity is the principle that objects retain their veracity and are intentionally modified by authorized subjects only.
- Availability is the principle that authorized subjects are granted timely access to objects with sufficient bandwidth to perform the desired interaction.
Different security mechanisms address these three principles in different ways and offer varying degrees of support or application of these principles. Objects must be properly classified and prioritized so proper security access controls can be deployed.
