Question 590
A Zero Trust platform administrator investigates this situation: An administrator is asked to permit two approved authentication endpoints but adds an entire top-level domain to the allow list, enabling unrelated resources. Which preventive control best reduces recurrence?
Explanation
Correct Answer
This safeguard mitigates url filtering explicit host versus wildcard: Record the business owner and exact scope of each URL exception and remove obsolete wildcard entries. The risk being controlled is: An overly broad URL pattern grants access to all matching hosts even when the request is for a fixed small endpoint list. A safeguard for an unrelated failure would not address it.
Incorrect Answers
Sensitive-data detection requires a suitable supported dictionary, identifier pattern or fingerprint rather than a weak generic token. “Validate DLP true-positive and false-positive fixtures and review supported data identifiers after policy updates” would remedy that alternative situation, but it would not correct the present issue: an overly broad URL pattern grants access to all matching hosts even when the request is for a fixed small endpoint list.
“Require log-level rule-hit evidence with every new category or exception deployment” is the supported response when a valid custom category does not change access until the selected policy order and matching rule action evaluate it for relevant users. Here the decisive response is “Record the business owner and exact scope of each URL exception and remove obsolete wildcard entries”, so that different intervention does not meet the stated requirement.
The desired user communication depends on supported URL blocking or coaching response configuration, not on DNS failure assumptions. “Review end-user warning content when updating risky-site policies or support escalation instructions” applies to that other condition. The reported evidence is an administrator is asked to permit two approved authentication endpoints but adds an entire top-level domain to the allow list, enabling unrelated resources; this alternative would address the wrong dependency.
