When evaluating access controls ServiceNow searches and evaluates

• A. From most specific match to the most generic match
• B. From most generic match to the most specific
• C. Based on roles
• D. Based on last update

Answer: (A)

When ServiceNow checks access rules, it uses the most specific rule first. The system looks for ACLs that could apply to the requested action on the target table and then evaluates them in order from the narrowly defined (most specific) rules to the broader (most generic) ones. This ensures that tightly scoped restrictions take precedence over general permissions, so a narrowly tailored ACL can override a broader rule and enforce the least-privilege principle. Roles play a part within those ACLs, but the critical factor is the specificity order of the matches. If no ACL grants access through the more specific rules, the evaluation falls back to the more generic ones; only if an applicable rule permits access (and no applicable deny blocks) is access allowed.
