Identity Management

Ensure that all users (internal, external and temporary) and their activity on IT systems (business application, IT environment, system operations, development and maintenance) are uniquely identifiable. Enable user identities via authentication mechanisms. Confirm that user access rights to systems and data are in line with defined and documented business needs and that job requirements are attached to user identities. Ensure that user access rights are requested by user management, approved by system owners and implemented by the security-responsible person. Maintain user identities and access rights in a central repository. Deploy cost-effective technical and procedural measures, and keep them current to establish user identification, implement authentication and enforce access rights.

  • Access management failing business requirements and compromising the security of business-critical systems
  • Unspecified security requirements for all systems
  • Segregation-of-duty violations
  • Compromised system information

Hide Control Practices  help

  1. Establish and communicate policies and procedures to uniquely identify, authenticate and authorise access mechanisms and access rights for all users on a need-to-know/need-to-have basis, based on predetermined and preapproved roles. Clearly state accountability of any user for any action on any of the systems and/or applications involved.
  2. Ensure that roles and access authorisation criteria for assigning user access rights take into account:
    • Sensitivity of information and applications involved (data classification)
    • Policies for information protection and dissemination (legal, regulatory, internal policies and contractual requirements)
    • Roles and responsibilities as defined within the enterprise
    • The need-to-have access rights associated with the function
    • Standard but individual user access profiles for common job roles in the organisation
    • Requirements to guarantee appropriate segregation of duties
  3. Establish a method for authenticating and authorising users to establish responsibility and enforce access rights in line with sensitivity of information and functional application requirements and infrastructure components, and in compliance with applicable laws, regulations, internal policies and contractual agreements.
  4. Define and implement a procedure for identifying new users and recording, approving and maintaining access rights. This needs to be requested by user management, approved by the system owner and implemented by the responsible security person.
  5. Ensure that a timely information flow is in place that reports changes in jobs (i.e., people in, people out, people change). Grant, revoke and adapt user access rights in co-ordination with human resources and user departments for users who are new, who have left the organisation, or who have changed roles or jobs.
