AuthorizationType (Complex Type)

Items

• name

  Flags: RAM,runtime

  Multiplicity: [0,1]

• description

  Flags: RAM,runtime

  Multiplicity: [0,1]

• decision

  Flags: RAM,runtime,AVals:2

  Multiplicity: [0,1]

• action

  Flags: RAM,runtime

  Multiplicity: [1,-1]

• phase

  Flags: RAM,runtime,AVals:2

  Multiplicity: [0,1]

• enforcementStrategy

  Flags: RAM,runtime,AVals:2

  Multiplicity: [0,1]

  Setting that specifies when to enforce the authorization. Default setting is to always enforce the authorization.

• object

  Flags: RAM,runtime

  Multiplicity: [0,-1]

  Object part from the (subject,action,object) authorization triple.

• item

  Flags: RAM,runtime

  Multiplicity: [0,-1]

• exceptItem

  Flags: RAM,runtime

  Multiplicity: [0,-1]

  Specification of items that are excluded from the scope of this authorization. I.e. the authorization applies to all the items except those items that are specified here.

  Note: there is subtle (but important) difference between not allowing access and denying access. Authorization that denies access specifies a final decision. Denied access cannot be allowed by any other authorization. Deny authorization are very strong from a security perspective, but it is extremely difficult to combine them with other authorizations. Therefore deny authorizations are used very rarely. On the other hand if the access is not allowed by a specific authorization then it can still be allowed by another authorization. This makes authorizations "mergeable". Not allowing access is usually the right approach. The exceptItem specification is a convenient way to "not allow" access to specific items.

  The item specification must not be combined with exceptItem. One or the other can be used, but not both. If neither item nor exceptItem is specified then it is assumed that the authorization applies to all items.

• target

  Flags: RAM,runtime

  Multiplicity: [0,-1]

  Target of the operation. E.g. an role that is being assigned. It can be considered an operation parameter. If no target is specified then the authorization applies to all possible targets.

• relation

  Flags: RAM,runtime

  Multiplicity: [0,-1]

  Relation(s) to which the authorization applies. This is applicable only to some authorizations, mostly those that create new object references (e.g. assign/unassign authorizations). If left empty it applies to all relations.

• limitations

  Flags: RAM,runtime

  Multiplicity: [0,1]

  Limitations of this authorization when it is applied to other authorizations. For example this specification may limit the power of attorney. It is only applicable to some authorization types.
