Which solution should the company’s security specialist recommend?
Instruct users to implement a retry mechanism every 2 minutes until the call succeeds.
Instruct the engineering team to consume a random grant token from users, and to call the CreateGrant operation, passing it the grant token. Instruct users to use that grant token in their call to encrypt.
Instruct the engineering team to create a random name for the grant when calling the CreateGrant operation. Return the name to the users and instruct them to provide the name as the grant token in the call to encrypt.
Instruct the engineering team to pass the grant token returned in the CreateGrant response to users. Instruct users to use that grant token in their call to encrypt.
Explanations:
Implementing a retry mechanism may help temporarily mitigate the issue, but it does not address the root cause of the AccessDeniedExceptions, which is likely related to timing or propagation delays after creating the grant. This approach could lead to unnecessary delays and confusion for users.
Using a random grant token and passing it to the CreateGrant operation does not solve the problem, as the grant token would still need to be valid and would not guarantee immediate access after the grant is created. This option does not ensure that the users can encrypt right after the grant is created.
Creating a random name for the grant and using it as the grant token does not effectively ensure that the encryption call will succeed immediately after the grant creation. The random name would not provide any inherent validity or guarantee for the subsequent operation, and it does not address the timing issues related to grant propagation.
This option directly addresses the problem by passing the grant token returned in the CreateGrant response to users. By using the provided token, users can successfully authenticate and perform encryption operations immediately after the grant is created, minimizing the risk of AccessDeniedExceptions due to timing issues.
If I’m not mistaken, the answer is:
Instruct the engineering team to pass the grant token returned in the CreateGrant response to users. Instruct users to use that grant token in their call to encrypt.
