I would stick to the Laprie taxonomy :

Dependability = Availability + Reliability + Safety + Integrity(not the SIL one, the true one) + Maintainability Security = Integrity + Confidentiality

The system consists of the following.

You, tied up in a chair, fixed to the floor. Along with your nemesis, with a rifle, who is pointing it at you, and is an excellent shot, and intends to shoot. Heshe pulls the trigger.

If the rifle is reliable, the system is unsafe.

If the rifle is completely unreliable, the system is safe.
