Users, groups, roles and service groups

While each user has an individual identity, and each IT service can be seen as an entity in its own right, it is often helpful to group them together so that they can be managed more easily. Sometimes the terms ‘user profile’ or ‘user template’ or ‘user role’ are used to describe this type of grouping.

Most organizations have a standard set of services for all individual users, regardless of their position or job (excluding customers – who do not have any visibility to internal services and processes). These will include services such as messaging, office automation, Desktop Support, telephony, etc. New users are automatically provided with rights to use these services.

However, most users also have some specialized role that they perform. For example, in addition to the standard services, the user also performs a Marketing Management role, which requires that they have access to some specialized marketing and financial modelling tools and data.

Some groups may have unique requirements – such as field or home workers who may have to dial in or use Virtual Private Network (VPN) connections, with security implications that may have to be more tightly managed.

To make it easier for Access Management to provide the appropriate rights, it uses a catalogue of all the roles in the organization and which services support each role. This catalogue of roles should be compiled and maintained by Access Management in conjunction with HR and will often be automated in the Directory Services tools (see section 5.8).

In addition to playing different roles, users may also belong to different groups. For example, all contractors are required to log their timesheets in a dedicated Time Card System, which is not used by employees. Access Management will assess all the roles that a user plays as well as the groups that they belong to and ensure that they provide rights to use all associated services.

Note: All data held on users will be subject to data protection legislation (this exists in most geographic locations in some form or other) so should be handled and protected as part of the organization’s security procedures.
