Common Information Security Targets

Other Security Targets

Restorability: Ensuring that no matter what happens, we can always roll-back a system into a good previous state.

Intrusion Detection: Notifying automatically unusual events in a system.

Steganography: Ability to communicate without revealing this activity to others.

Note that steganography is a stronger requirement than confidentiality because not only you want to keep secret what you communicate but also the fact that you communicate secretly.

Note: No list is ever completed, including this one.
