Why Roles?

When done right, enterprise roles offer a significant increase in operational efficiency for IT audit and for the business user. Today, the business is tasked with owning and operating much of the data access process, and enterprise roles (from here on out just referred to as roles) offer a mechanism for simplifying that process. Roles also allow an organization to meaningfully move toward a “manage by exception” paradigm by defining known groups of access aligned with business activities and functions and highlighting where the current state differs from the model view.

Quite simply, roles make certification and access reviews simpler, faster, and more business-friendly. During the business certification process, roles allow the user to focus on the assignment of groups of entitlements rather than getting lost in individual entitlement configuration. This is often referred to a role assignment certification. A separate process can then focus on the composition of a given role – so what’s in the role ready to be assigned to an individual – this is often referred to as a role composition certification.

Roles enable a structured control model for the lifecycle of entitlement changes. Imagine needing to add a new application access profile for all “basic users.” Roles help prevent having to manage these changes at an individual user or account level. Instead, changes to the access assignment model can be made at the role level and pushed out to each user by the provisioning process in an automated fashion.

Roles also greatly enhance the security audit and controls process. Auditors and security professionals can validate access and access management processes at the role level, rather than working with individual entitlements and individual assignments. This vastly simplifies the administration and oversight burden and allows specialists to focus on defining and validating governance policies instead.

Finally, roles provide an important “model construct.” A role (and its supporting metadata and control processes) provides a concrete model construct around which the business and IT can come together to define, capture, and enforce “the desired state,” hence helping to ensure that the right people have the right access to the right data.
