Central Authorization Policies

  • Article

A Central Authorization Policy (CAP) collects the specific authorization rules (CAPRs) into a single policy. To allow the specific authorization rules (CAPRs) to be combined into the holistic authorization policy of the organization, CAPRs can be referenced together and applied to a set of resources. This is done by collecting multiple (by reference) into a CAP. Once a CAP is defined it can be distributed consumed by resource managers to apply the organizations authorization policy to resources.

A CAP has the following attributes:

  • Collection of CAPRs – a list of references to existing CAPR objects
  • An identifier (Sid)
  • Description
  • Name

A CAP is evaluated during access evaluation for files and folders on which an administrator enables it. During an AccessCheck call, the CAP check is logically combined with the discretionary ACL check; this means that in order to obtain access to a file to which the CAP applies, a user needs to have access both according to the CAP (its associated CAPRs) and the discretionary ACL on the file.

Example CAP:

CORPORATE-FINANCE-CAP]
CAPID=S-1-5-3-4-56-45-67-123
Policies=HBI-CAPE;RETENTION-CAPR

CAP Definition

A CAP is created and edited in Active Directory using a new UX in ADAC (or PowerShell) that allows the administrator to create a CAP and specify a set of CAPRs that make up the CAP.
