FAQ-000532 - Custom Settings and Configuration Security / Security Review and Compliance

A protected custom setting field flagged for insecure storage is considered a vulnerability because it can be accessed and modified by the org admin, other packages, or untrusted code within the subscriber org. This exposure increases the risk of sensitive data being compromised. To mitigate this, sensitive data should be stored in: - Protected custom metadata API fields - Encrypted custom objects with the encryption key stored securely - Named credentials, depending on the use case and access requirements

The FAQ content is accurate and well-structured, but I made minor improvements for clarity and conciseness per the brand and tone guidelines. The main changes were: (1) removing unnecessary section headers (Category/Subcategory) that don't add value to the answer, and (2) slightly improving the flow by making the mitigation strategies more directly connected to the vulnerability explanation. For the security rules selected: **ProtectSensitiveData**: This rule is directly relevant because the FAQ discusses the core issue of protecting sensitive data from insecure storage. The FAQ specifically addresses "sensitive data being compromised" and provides mitigation strategies for secure data storage, which aligns perfectly with this rule's purpose of ensuring sensitive data protection. **ApexSuggestUsingNamedCred**: This rule is applicable because the FAQ explicitly recommends "Named credentials, depending on the use case and access requirements" as one of the mitigation strategies for secure storage. The FAQ content directly advocates for using named credentials as a security best practice, which matches this rule's guidance.
