Data system owner determines the access roles to the system in relation to the tasks of users. The compliance of the actual access rights with the planned ones must be monitored and the rights reassessed at regular intervals.
When reviewing access rights, care must also be taken to minimize admin rights and eliminate unnecessary accounts.
The organization implements role-based access control with predefined access roles for the various protected assets that entitle access to the associated asset. Strictness of the access roles should reflect the security risks associated with the asset.
The following should be considered to support access management:
The need-to-know principle grants access only to information that an individual needs to perform his or her task. Different tasks and roles have different information needs and thus different access profiles.
Separation of tasks means that conflicting tasks and responsibilities must be separated in order to reduce the risk of unauthorized or unintentional modification or misuse of the organisation's protected assets.
