Definition 1

The average period during which access decision factors are only subject to slight disturbance, prolonging the validity of previously defined access permissions. A disturbance of access decision factors beyond some threshold triggers the requirement to adapt access permissions. Distinct access control methods (e.g. ACL, RBAC, ABAC, PBAC) are varyingly efficient in the way they enable modifications of access permissions.

Quotes

3.1 Stability of Access Decision Factors – When the basis for access decisions is relatively stable, use of mechanisms such as ACLs lends itself more readily. Administrative processes typically required to maintain these lists are time-intensive and not particularly well suited to situations where significant changes and updates are required frequently. On the other hand, use of a flexible Attribute Management enterprise service where attributes can be easily managed, may be more responsive and thus, more operationally effective.
