FAQ-000736 - Data Storage and Encryption Security / Vulnerability Identification and Remediation

### Common Insecure Data Storage Issues: 1. **Storing Sensitive Data in Plain Text**: Sensitive information like API keys or passwords stored in plain text can be accessed by unauthorized users. **Solution**: Encrypt sensitive data and store encryption keys separately in protected custom settings or metadata. 2. **Improper Use of Visibility Settings**: Sensitive fields with public visibility can be accessed by unauthorized users. **Solution**: Mark sensitive fields as private or protected to restrict access. 3. **Insecure Storage of OAuth Secrets**: OAuth secrets and access tokens stored insecurely can be compromised. **Solution**: Store them securely in protected custom settings or metadata and avoid transmitting them outside Salesforce. 4. **Logging Sensitive Data**: Logging sensitive information like passwords or keys in production environments can expose data. **Solution**: Redact or omit sensitive data from logs. 5. **Insecure Use of Custom Objects**: Sensitive data stored in custom objects without encryption or access restrictions can be exposed. **Solution**: Encrypt the data and enforce proper CRUD/FLS checks to restrict access. 6. **Unprotected Storage Settings**: Storing sensitive data (e.g., API keys, client secret keys) in unprotected or public settings instead of using protected custom settings or encrypted fields. 7. **Unencrypted Field Storage**: Failing to encrypt sensitive data before storing it in object fields. 8. **Exposure in Logs and URLs**: Leaving sensitive information in debug logs, URLs, or unencrypted forms, exposing it to unauthorized access. 9. **Deprecated Storage Mechanisms**: Using deprecated or insecure storage mechanisms that lack adequate protection. 10. **Inadequate Documentation**: Not addressing false positives related to sensitive data storage by providing proper documentation or mitigation strategies. ### How to Avoid These Issues: 1. **Encrypt Sensitive Fields**: Use secure encryption methods for sensitive data like API keys or passwords, and store encryption keys in protected custom settings. 2. **Avoid Logging Sensitive Data**: Don't log sensitive information (e.g., passwords, keys) in production environments. Redact or omit such data from logs. 3. **Follow Security Standards**: Adhere to enterprise security standards when exporting or storing sensitive data on the Salesforce platform. 4. **Use Scanning Tools**: Perform manual testing and use scanning tools to identify vulnerabilities. Address flagged issues or document them as false positives if applicable. 5. **Collaborate with Security Experts**: Work with a security expert during development to ensure compliance with security guidelines. To mitigate these issues, follow enterprise security standards, use encryption, validate and restrict access with proper permissions, and avoid exposing sensitive information in logs or public fields.

The FAQ content is generally accurate and comprehensive. I made minor improvements to enhance clarity and flow without changing the core content or adding new points. The changes include: 1) Better formatting of the numbered list items 6-10 by giving them descriptive titles instead of full sentences, which improves readability and consistency with items 1-5; 2) Minor wording refinements for clarity ("Do not log" to "Don't log" for more conversational tone). All security rules selected are highly relevant: ApexBadCrypto relates to the encryption recommendations throughout the FAQ; ApexCRUDViolation and ApexSharingViolations relate to the CRUD/FLS checks and access restriction mentions; ApexSuggestUsingNamedCred relates to secure storage of credentials and OAuth secrets; AvoidHardcodedCredentialsInFieldDecls, AvoidHardcodedCredentialsInVarDecls, and AvoidHardcodedCredentialsInVarAssign all relate to the FAQ's extensive discussion of avoiding hardcoded sensitive data like API keys and passwords; ProtectSensitiveData relates to the overall theme of protecting sensitive information in storage.
