FAQ-000505 - Custom Settings and Configuration Security / Protected Custom Settings vs Other Storage Methods

Using a Protected Custom Setting or Custom Metadata Type is preferred over an encrypted field on a custom object for storing secrets because: - **Enhanced Security**: Protected Custom Settings and Custom Metadata Types are designed to restrict access, ensuring secrets aren't exposed to unauthorized users. - **Access Control**: Encrypted fields may still be visible to users with certain permissions, whereas Protected Custom Settings and Custom Metadata Types inherently provide better access control. - **Better Management**: They allow for secure and separate storage of secrets, such as encryption keys, aligning with enterprise security standards. This makes them a more secure and reliable choice for handling sensitive data like secrets.

The FAQ content is accurate and well-structured, but I made minor improvements for clarity and tone consistency with the brand guidelines. Changed 'are not exposed' to 'aren't exposed' to use contractions as recommended. The information aligns well with security best practices and doesn't contain outdated content. The selected security rules relate to this FAQ because: ApexSuggestUsingNamedCred relates to the FAQ's discussion of secure credential storage alternatives (the FAQ explains why Protected Custom Settings are preferred for storing secrets like credentials). AvoidHardcodedCredentialsInFieldDecls, AvoidHardcodedCredentialsInVarDecls, and AvoidHardcodedCredentialsInVarAssign all relate to the FAQ's core message about avoiding insecure storage methods for sensitive data like secrets and credentials. ProtectSensitiveData directly relates to the FAQ's central theme of protecting sensitive information through proper storage mechanisms rather than less secure alternatives like encrypted fields.
