  7. 7. TheABAC trend 7 2005 XACML version 2.0: Concept production-ready for enterprise needs. 2009 US Federal CIO Council – (FICAM) Roadmap and Implementation Plan v1.0 advocates ABAC 2006 Axiomatics founded. First project: a nation- wide eHealth service. 2011 FICAM v2.0: ABAC recommended access control model for promoting information sharing between diverse and disparate organizations. 2013 XACML version 3.0 2014 NIST Guide on ABAC 2014 Gartner predicts: ”By 2020, 70% of all businesses will use ABAC as the dominant mechanism to protect critical assets, up from 5% today.” ABAC = Attribute Based Access Control © 2014 Axiomatics AB Introduction
  8. 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. 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. 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 © 2014 Axiomatics AB 10 Introduction
  11. 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 © 2014 Axiomatics AB 11 Introduction
  12. 12. Why organizations invest in ABAC technology © 2014 Axiomatics AB 12 Consolidated infrastructure Enhanced security Business enabler Compliance Expose data and APIs to customers and partners Write once, Enforce everywhere Consistent authorization enforcement across applications Implement legal frameworks Business drivers
  13. 13. Attribute Based Access Control (ABAC) objectives  Get competitive advantage and create new revenue streams  Minimize the risk of fraud with dynamic, real-time access control  Meet global regulatory and privacy requirements  Cut time to market and streamline internal development © 2014 Axiomatics AB 13 Business drivers

  15. 15. Legacy access control Attribute based access control © 2014 Axiomatics AB 15 Legacy access controls fail in dynamic environments Business challenge
  16. 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. © 2014 Axiomatics AB 16 ROI=ROI of new service which gives a competitive advantage Business values

  19. 19. The RBAC Sudoku © 2014 Axiomatics AB 19 Business challenge A B C
  20. 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.) © 2014 Axiomatics AB 20 Business challenge
  21. 21. Achievements made – return on investment (ROI)  “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” © 2014 Axiomatics AB 21 Business values

[…] Application-external authorization must ensure applications at all times comply with changing and country specific regulations.” © 2014 Axiomatics AB 25 ROI=Avoiding fines, avoiding reputational damage Business values

  29. 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)) …. © 2014 Axiomatics AB 29 Implementing authorization in applications Business challenge
