  2. User access rights for moving from one role to another within the same organization should be reviewed and re-allocated;
  3. The privileged access rights authorizations should be reviewed frequently
  4. The allocation of access rights should be regularly reviewed to ensure that unauthorized privileges are not obtained;
  5. Regular reviews should be registered for changes to privileged accounts.

A.9.2.6 Removal or Adjustment of Access Rights

Control- Access rights of all employees and external users to information and information processing facilities should be waived upon termination of jobs, contract or agreement, or changed upon adjustment.

Implementation Guidance- Upon termination, an individual’s access rights to information and assets associated with the facilities and services for information processing should be removed or suspended. Whether access rights should be removed will be determined. Changes in employment should be reflected in removing all access rights which have not been approved for the new job. The access rights which should be removed or adjusted include the physical and logical access rights. The removal or adjustment of keys, identification cards, information processing facilities, or subscriptions may be done by removal, revocation, or replacement. Any documentation identifying employees and contractors’ access rights should reflect removal or adjustment of access rights. If a departing employee or external user has identified passwords that are still active for user IDs, these should be updated after termination or change of job, contract, or agreement.

Access rights for information and assets related to information processing facilities should be restricted or withdrawn before the termination or change of jobs, based on the following risk factors :

  1. Whether termination or alteration is initiated by the employee, external user or management team, and the reason for termination;
  2. Current responsibilities of client, external user or some other user;
  3. Price of currently available assets.

In the current era, it’s always advisable to limit and control access privileges. For an organization, it’s really important that its information assets and accessibility to those assets should always be protected. There should exist Access rights to particular users and should be reviewed regularly. Annex 9.2 covers the guidelines and implementation of controls to safeguard data getting accessed by unauthorized users or to users who are departed from the organization.

Other Information- Access rights can be divided under some circumstances on the grounds that more people are eligible than the leaving employee or external user, e.g. group IDs. In these cases, departing individuals should be excluded from all group access lists, and arrangements should be made to warn all other employees and external party users concerned not to share this information with the departing person.

In the event of terminations initiated by management, disgruntled employees or external users can deliberately corrupt information or sabotage information processing facilities. In situations where employees resign or are fired, they can be tempted to collect information for potential use.
