Question 440
At Brookside Manufacturing, the industrial security team is conducting a plant safety and IT security assessment under requirements for production continuity and controlled test windows. The team now needs objective retest evidence for: A single stolen refresh token remains valid after the account password is reset during incident containment. Which result BEST demonstrates successful remediation?
Explanation
Correct Answer
Previously issued tokens fail on renewal and an authorized user can establish a fresh session after remediation. The observable result demonstrates that the documented condition, A single stolen refresh token remains valid after the account password is reset during incident containment. has been addressed. The planned remediation is: Implement provider-supported refresh token revocation and session termination when credentials are compromised. This is a stronger validation than a saved ticket or unverified claim by Brookside Manufacturing.
Incorrect Answers
The authenticated session uses a fresh identifier and the pre-authentication identifier cannot authorize the user. That observation would verify another scenario: A login system accepts the same pre-authentication session identifier after a user signs in, increasing session fixation exposure. The corrective step for that other scenario is: Regenerate or rotate the session identifier at successful authentication and important privilege changes. But Brookside Manufacturing is evaluating: A single stolen refresh token remains valid after the account password is reset during incident containment. The necessary outcome is: Previously issued tokens fail on renewal and an authorized user can establish a fresh session after remediation.
Unusual sessions trigger additional verification and stale sessions cannot perform privileged actions. That observation would verify another scenario: A support agent's account is active from multiple unfamiliar regions but the application never rechecks session risk or recent authentication. The corrective step for that other scenario is: Add risk-based session controls, short idle expiration and protected reauthentication for sensitive operations. But Brookside Manufacturing is evaluating: A single stolen refresh token remains valid after the account password is reset during incident containment. The necessary outcome is: Previously issued tokens fail on renewal and an authorized user can establish a fresh session after remediation.
Removing or altering browser variables does not bypass authorization or grant access to protected requests. That observation would verify another scenario: A web system stores session state only in a browser variable and treats its presence as proof that the server accepted authentication. The corrective step for that other scenario is: Validate session identity and authorization on the server for every protected endpoint instead of trusting client-controlled state. But Brookside Manufacturing is evaluating: A single stolen refresh token remains valid after the account password is reset during incident containment. The necessary outcome is: Previously issued tokens fail on renewal and an authorized user can establish a fresh session after remediation.
