Question 760
A network team wants safe evidence that its service account cannot authenticate to unrelated SMB hosts. Which authorized assessment decision best addresses this particular situation?
Explanation
Correct Answer
Use designated synthetic credentials and read-only authentication tests. This answer directly addresses the described constraint. A service account's trust scope affects lateral movement potential. Successful validation requires: The test account is accepted only by authorized service endpoints.
Incorrect Answers
That approach concerns a different situation: a Windows domain has AD Certificate Services templates granting enrollment privileges to unintended users. Misconfigured certificate templates can grant unintended authentication capabilities. The required result is that the test account is accepted only by authorized service endpoints. The appropriate action is: Use designated synthetic credentials and read-only authentication tests.
That relates to a different issue: An assessor detects unsupported SMB dialects enabled for a legacy file service. Older dialects can lack modern session security features. That is not a direct remedy for the requested outcome: The test account is accepted only by authorized service endpoints. The appropriate action is: Use designated synthetic credentials and read-only authentication tests.
It would address a switch port is configured to accept tags from an untrusted endpoint. The relevant reason in that case is: Incorrect trunk or native VLAN settings can break intended network segregation. Here the required success condition is the test account is accepted only by authorized service endpoints. The appropriate action is: Use designated synthetic credentials and read-only authentication tests.
