Question 370
At Seabright Municipal Works, a team reports that it corrected the following problem affecting public service networks and records: A security appliance retains vendor default accounts and shared passwords across multiple deployments. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
Credential audits find no active default logins and every change is attributable. This is the decisive evidence for the original problem: A security appliance retains vendor default accounts and shared passwords across multiple deployments. It verifies that the intended corrective control—Replace or disable defaults and enforce individual least-privilege management identities—works in the relevant environment; a completed change ticket alone would not prove the outcome at Seabright Municipal Works.
Incorrect Answers
The benchmark review records justified exceptions and verified protection for retained services. This would be relevant evidence for a different failure: A network engineer copies a benchmark recommendation that would disable a required feature without review, usually addressed by Apply hardening with documented applicability, exceptions, and compensating controls. It does not demonstrate that the current problem at Seabright Municipal Works was resolved. The specific required evidence is: Credential audits find no active default logins and every change is attributable.
Unauthorized subnets cannot open management sessions while the approved jump host succeeds. This would be relevant evidence for a different failure: A device accepts management connections from every routed subnet even though only a jump host should administer it, usually addressed by Restrict management-plane access using ACLs or supported trusted-host controls. It does not demonstrate that the current problem at Seabright Municipal Works was resolved. The specific required evidence is: Credential audits find no active default logins and every change is attributable.
Patch and configuration evidence resolves the identified exposure without breaking expected traffic. This would be relevant evidence for a different failure: A Cisco Secure Firewall deployment uses outdated software with published security fixes unassessed, usually addressed by Compare its release and configuration to supported CIS-style hardening and vendor advisories. It does not demonstrate that the current problem at Seabright Municipal Works was resolved. The specific required evidence is: Credential audits find no active default logins and every change is attributable.
