## [A] Availability

[A] availability
Assurance that the authorised users have access when they require it to the information and its associated assets.
How important would it be if the asset were not available?
An asset has a great value from the point of view of availability when the consequences of a threat affecting its availability are serious. On the other hand, an asset has no appreciable value from the point of view of availability when no damage is caused if it is frequently unavailable for long periods. Availability is a property that affects all types of assets. Often, availability requires treatment in steps because the cost of non-availability increases non-linearly with the duration of the stoppage, from short interruptions without importance, and interruptions that cause considerable damage to irrecoverable interruptions: the organisation is finished.
