IBM Pulse 2012 presentation by Alex Ivkin (Prolifics) and Grey Thrasher (IBM)

Synthesizing the business view of IT resources with the technical implementation of Role Based Access Control remains one of the toughest challenges in Identity Management today. We will walk through a real-world use case to understand how organizations can utilize the new IBM Role and Policy Modeler (RaPM) tool to discover essential business relationships and map them to IT access permissions, creating the schema for a comprehensive RBAC system. We will explain how the design criteria provided by RaPM has enabled the foundation of a comprehensive Identity and Role Lifecycle Management structure. The follow-on implementation of an RBAC system in the Identity Provisioning platform, IBM Tivoli Identity Manager, will be explored, as well as how this organization is automating access privileges, simplifying internal security controls and reducing the complexity of audit and compliance enforcement.

  • Separation of duty ensures that the same user cannot have conflicting roles that would provide them with an unacceptable level of authority. Constraints can be applied to user/role assignments (static constraints), to session/role assignments (dynamic constraints), or to role hierarchies.
  • To conclude, I would like to summarize that IBM has shown leadership in the RBAC space for a long time. We have made these role management capabilities available in an integrated solution for Identity Management. And we have targeted our delivery of strong functionality to what enterprises need today. Our IAM Governance strategy and vision also encompasses a broader perspective that goes beyond role management. While we are completing this vision with role modeling and lifecycle management, we are also well prepared to make the next evolutionary step into identity analytics.Thanks for your time and attention. I would like to answer any questions you may have.***************Win dealArla Foods: Originally acquired TIM to have a handle over the 10+% of orphan accounts in their SAP applications that cause them to fail ISO 17799 audit. MN Security helped them reduce the number of roles by 95% using TIM's SOD, certification, approval workflow, and UP. 50% reduction in service desk calls.GameStop - game retailer with 3000 employees. Got TIM because it was failing audits due to churn and lack of access tracking. Orphan accounts, obsolete accounts. They needed to understand their access and clean it.CommonWealth Bank (Australia) - TIM 4.6 customer that bought Sailpoint, and then changed by Sun RM because TIM did not cover roles. Now wants to get TIM 5.1. (48K users, 125apps)

    4. 4. Business challenges • Difficulty in the business understanding of security information causing a rubber stamp process, or simply too much data to sort through for the business • Challenges in the quarterly attestation cycle • Challenges for supervisory personnel understanding how "least privilege" works in their business unit • Onboarding (new hire user adds) requests requiring additional time and effort becuase access requests are submitted on a case by case basis using individual forms • Challenges in managing the access of persons who transfer between jobs, creating complex modification requests for access on a case by case basis • Risk due to inappropriate access, which could be misuse or simply audit findings - this is due to mirrored access (make Johns access look like Marys) that may grant too much permission, or through job transfers where old access is not removed properly
    5. 5. Role Based Access Control• RBAC is a methodology to align security entitlements to persons through an abstraction of organizational responsibilities using job function and relationship to the organization. The idea is to use roles to represent common access rights for users as sets of privileges on different systems. Direct access assignmentsBefore today are complex, difficult to track and change when needed • Simplify roles and access assignments • Ability to handle growth and scale • Facilitate accountability and compliance Role Based Access ControlAfter (RBAC) offers an effective operational model to drive IAM Governance
    6. 6. Business Benefits of RBAC • Reduce risk by ensuring people are limited to the required access dictated by their job function • Reduce dormant time for new hires during onboarding because their well defined access can be instantiated automatically • Simplify the attestation and audit process by reviewing privileges that are exceptions to the roles instead of reviewing every entitlement • Increase accuracy in the attestation process due to an easier to understand business interface to information security data • Simplify the cross boarding process and reduce the risk of personnel dragging inappropriate entitlements to their new job function • Address compliance requirements through the inherent linkage to organizational definitions of least privilege and separation of duty
    7. 7. Reality check  How many companies want to do RBAC?  How many companies are doing RBAC?  How many companies successfully completed RBAC in 2011?  Our study showed:  97% of IdM customers in 2011 agreed that Role Based Access Control is a solid approach to tackle problems of compliance and security control  A third has engaged in RBAC design and implementation, internally and externally  Less than a tenth achieved the goals  Why?7
