The FAQ content is generally well-structured and covers important security practices for handling sensitive configuration data. No significant issues were found with outdated content or security confusion. The answer appropriately recommends Protected Custom Settings for secure storage, custom UIs for controlled access, and proper access restrictions - all of which are current best practices.
I selected the ProtectSensitiveData rule because it directly relates to the core content of this FAQ. The FAQ is specifically about "sensitive configuration data" and how to "handle" it securely while making it accessible only to authorized users (org administrators). The ProtectSensitiveData rule focuses on protecting sensitive data from unauthorized access, which aligns perfectly with the FAQ's guidance on using Protected Custom Settings, creating secure custom UIs, and restricting access through profiles or permission sets. The FAQ's entire premise is about protecting sensitive data while providing controlled access, which is exactly what this security rule addresses.
