Question 690
A team must implement a control for the following situation: A research group shares one privileged login across administrators and cannot attribute changes. Which design detail fits best?
Explanation
Correct Answer
Separate privileged identities, approve rights and monitor privilege assignments and use. This design addresses the issue that a research group shares one privileged login across administrators and cannot attribute changes. It implements the decision to apply proportionate least-privilege identity and access controls to sensitive technology. Verify that tests show only authorized named subjects receive necessary privileges and actions are attributable. A failure would be using shared admin credentials as a shortcut to expedite a deployment.
Incorrect Answers
Specify pre-engagement conditions, security awareness, access changes and end-of-engagement duties. That approach concerns annex a people security controls, as when contractor agreements contain no confidentiality obligations even for highly sensitive data access. This case instead requires the team to separate privileged identities, approve rights and monitor privilege assignments and use. The remaining risk is unauthorized access and absence of accountability for high-impact changes. Case: A research group shares one privileged login across administrators and cannot attribute changes.
Document needed controls, applicability rationale, inclusion status and implementation status. That approach concerns statement of applicability rationale, as when a healthcare supplier excludes a relevant control without documenting any justification for that omission. This case instead requires the team to separate privileged identities, approve rights and monitor privilege assignments and use. The remaining risk is unauthorized access and absence of accountability for high-impact changes. Case: A research group shares one privileged login across administrators and cannot attribute changes.
Record treatment choice, implementation plan, accountable acceptance and trace to the underlying risk. That approach concerns risk treatment options and approvals, as when a data processor has documented a high risk but nobody decides whether to mitigate, avoid, share or retain it. This case instead requires the team to separate privileged identities, approve rights and monitor privilege assignments and use. The remaining risk is unauthorized access and absence of accountability for high-impact changes. Case: A research group shares one privileged login across administrators and cannot attribute changes.
