The document discusses the business case for Attribute Based Access Control (ABAC), highlighting its advantages over legacy access controls in dynamic and collaborative environments. It emphasizes ABAC's ability to enhance security, enable efficient information sharing, and ensure compliance with regulatory standards. The presentation also outlines the return on investment (ROI) from implementing ABAC and its role in reducing risks, improving software development processes, and maintaining governance.

”By 2020, 70% of all
businesses will use
ABAC as the dominant
mechanism to protect

up from 5% today.”

Introduction

8. What is Attribute Based Access Control (ABAC)?
 A mode of externalized authorization
 Authorization policies/rules are managed in a centralized service (deployment
can be centralized/distributed/hybrid)
 The Extensible Access Control Markup Language (XACML) is an example of an
ABAC system
 Policies utilize attributes to describe specific access rules, which is why it is
called attribute based access control
© 2014 Axiomatics AB 8
Introduction

9. Example from NIST report
 “This flexibility [of ABAC] provides the greatest breadth of subjects to access
the greatest breadth of objects without specifying individual relationships
between each subject and each object”
 Nurse Practitioners in the Cardiology Department can View the Records of
Heart Patients
 Variables in the policy language enable very efficient policy structures – reducing the
maintenance load
 Management of heart patient records is part of the business application – not an IT
function
 Multiple attributes must be available for policy evaluation – either as part of the access
request or retrieved from source
© 2014 Axiomatics AB 9
Introduction

10. NIST example - expanded
 Nurse Practitioners can View the Records of Patients in the same Department
they are assigned to
 This rule can apply to all departments in the hospital
 Add a new department or change names of department and the rule does not change
 Rule compares department of the Nurse Practitioner to the department of the Patient
 Avoids the role explosion effect of RBAC models

Introduction

11. Why are we seeing this shift to ABAC?
 Todays’ business environment is more global, dynamic and collaborative
 First generation access models cannot cope in a “need to share” world
 Users demand access to any data, from any device, at any time

16. Achievements made – return on investment (ROI)
 Question: Before you went for Attribute Based Access Control
(ABAC), how would you have approached the type of solution
you now have built?
 Answer: We wouldn’t. It would simply not have been possible
to build this type of service with the access control models we
used before.

20. Using ABAC to overcome the RBAC weakness
 Solution:
To authorize a Service Entry and Release, enforce the following XACML rule:
 PERMIT Service Entry and Release for users with Cost Center Signature
Authority for Purchase Orders of their own Cost Centers providing they were
not previously involved in the creation, editing or approval of the related
Purchase Order or the corresponding Vendor or Service provider account.
 Result:
Multiple attributes combined [cost center, PO and Vendor approver etc.] –
not just the role of the user – are considered to minimize the risk
(in our example the risk of individuals releasing service entries for their own
fraudulent purchase orders.)

 “Maintain separation of duties so that no one person has too
much control”
 “Reduce risks of data breaches, data leakage and identity theft”
 “Prevent or limit unauthorized bank system access or use”

29. Legacy access control
 Authorization checks repeated over
and over in code:
if (!User.IsInRole("Administrators"))
{
Msg.Text = “Acccess denied.";
ListBox.Visible = false;
return;
}
 Imagine more conditions: data
classification, ListBox.DataSource,
administrator’s clearance level ….
Attribute based access control
 Write once, use many times –
simply send an access request to the
authorization service
Req=BuildRequest(UserID,ListBox)
if (!PDPPermit(Req)) ….

 52 %: Portion of total effort spent fixing ‘architecturally
