Removing or restricting rightsJust as Access Management provides rights to use a Service, it is also responsible for revoking those rights. Again, this is not a decision that it makes on its own. Rather, it will execute the decisions and policies made during Service Strategy and Design and also decisions made by managers in the organization. Removing access is usually done in the following circumstances:
In other cases it is not necessary to remove access, but just to provide tighter restrictions. These could include reducing the level, time or duration of access. Situations in which access should be restricted include:
4.5.6 Triggers, input and output/inter-process interfaces Access Management is triggered by a request for a user or users to access a service or group of services. This could originate from any of the following:
Access Management should be linked to the Human Resource processes to verify the user ’s identify as well as to ensure that they are entitled to the services being requested. Information Security Management is a key driver for Access Management as it will provide the security and data protection policies and tools needed to execute Access Management. Change Management plays an important role as the means to control the actual requests for access. This is because any request for access to a service is a change, although it is usually processed as a Standard Change or Service Request (possibly using a model) once the criteria for access have been agreed through SLM. SLM maintains the agreement s for access to each service. This will include the criteria for who is entitled to access each service, what the cost of that access will be, if appropriate and what level of access will be granted to different types of user (e.g. managers or staff). There is also a strong relationship between Access Management and Configuration Management. The CMS can be used for data storage and interrogated to determine current access details.
