ONE TIME USE PASSWORD FOR TEMPORARY PRIVILEGE ESCALATION IN A ROLE-BASED ACCESS CONTROL (RBAC) SYSTEM

摘要

Techniques to facilitate temporary escalation of access privileges for a control program associated with a machine system in an industrial automation environment are disclosed. In at least one implementation, a request is received from a user for a temporary access level increase to utilize protected functions of the control program. An encrypted string is generated comprising a temporary password authorized to access the protected functions of the control program. The encrypted string is provided to the user, wherein the user provides the encrypted string to an administrator and the administrator authenticates the user for the temporary access level increase, decrypts the temporary password, and provides the temporary password to the user. A login request is received from the user with the temporary password, and the temporary access level increase is responsively granted to allow the user to utilize the protected functions of the control program.
