Subject: First Opportunity to comment on XACML v3.0 Separation of Duties v1.0 from the XACML TC - ends January 4th

OASIS Members and other interested parties,

We are pleased to announce that XACML v3.0 Separation of Duties Profile Version 1.0 CSD01 from the OASIS eXtensible Access Control Markup Language (XACML) TC is now available for public review and comment. This is the first public review for this work.


Separation of duties (SoD) is a security principle applied to minimize fraud, misuse of information, conflicts of interest and user errors by requiring that a task can only be completed by the active involvement of two or more people.

This specification defines a method for supporting separation of duties within XACML policies using obligations and allowing the full generality of attribute-based access control. In particular, duties are not required to be associated with subject roles.

The eXtensible Access Control Markup Language (XACML) defines categories of attributes that describe entities of relevance to access control decisions. XACML rules, policies and policy sets contain assertions over the attributes of these entities that must be evaluated to arrive at an access decision.

TC Description:

The XACML TC specifies access control standards, based on the Attribute-based Access Control model (ABAC). The core of this work is the specification of the syntax and semantics of a policy language called XACML. Current work in the TC consists mostly of defining additional profiles of various types which build on version 3.0 of the XACML core specification.
