FAQ-000781 - External Authentication and Integration Security / External Data and Service Security

Creating a centralized service for third-party API authentication has several security implications that need careful attention: 1. **Secure Authentication Mechanisms**: Use secure methods like OAuth for third-party integrations. Consider using Named Credentials to securely manage authentication details. Avoid exposing sensitive information, such as API credentials or cryptographic secrets, in debug logs. 2. **Request Validation**: Validate all incoming requests to prevent vulnerabilities like open redirection. 3. **Secure Storage**: Protect tokens or credentials using secure storage mechanisms (e.g., Named Credentials, protected custom settings, or metadata). Ensure they're not accessible for unauthorized editing. 4. **Token Updates**: Use secure methods, like a restricted REST API endpoint with specific permission sets, for updating tokens. Ensure the endpoint is thoroughly vetted to avoid backdoors. 5. **Secure Connections**: Use HTTPS for all connections to third-party APIs and comply with TLS/SSL configuration requirements. Arbitrary servers or schemes should only be allowed with a valid business case and additional security measures. 6. **Regular Audits**: Conduct regular audits and vulnerability scans to identify and mitigate risks. By addressing these considerations, you can enhance the security of your centralized authentication service.

The existing FAQ content is accurate but can be enhanced to align better with Salesforce security best practices. The main improvement involves mentioning Named Credentials as the preferred method for managing authentication details in point 1, and referencing them again in point 3 alongside existing secure storage options. This aligns with Salesforce's recommended approach for securely handling third-party API credentials. Selected security rules relate to the FAQ content as follows: - ApexSuggestUsingNamedCred: Directly relates to point 1 and 3 about secure authentication and credential storage - Named Credentials are the recommended approach for third-party API authentication - ApexInsecureEndpoint: Relates to point 5 about ensuring HTTPS connections and secure endpoints - ApexOpenRedirect: Directly mentioned in point 2 about request validation to prevent open redirection vulnerabilities - AvoidHardcodedCredentialsInFieldDecls/VarDecls/VarAssign/HttpHeader: All relate to points 1 and 3 about not exposing API credentials and using secure storage - AvoidInsecureHttpRemoteSiteSetting: Relates to point 5 about HTTPS connections and TLS/SSL requirements - AvoidDisableProtocolSecurityRemoteSiteSetting: Relates to point 5 about maintaining protocol security for remote connections - UseHttpsCallbackUrlConnectedApp: Relates to point 5 about HTTPS requirements for secure connections
