FAQ-001005 - Feature Flagging and Conditional Access Security / Secure Feature Flag Implementation

The most secure way to implement feature flagging for controlling user access to objects or components in Salesforce is by using a combination of Custom Permissions, Permission Sets/Permission Set Groups, and USER_MODE database operations. This approach leverages the Salesforce security trust layer to ensure that even if a user manipulates client-side code, they cannot access functionality they are not permitted to see. **Secure Feature Flagging Framework** **Define Custom Permissions (The Flag):** Create a Custom Permission (e.g., FEAT_NewDashboard) for each feature. This acts as the toggle. Why: Custom Permissions are secure, can be checked in Apex, LWC, and Flows, and cannot be easily bypassed by end-users. **Assign via Permission Sets (The Target):** Create a Permission Set and add the Custom Permission to it. Assign this Permission Set to specific users or groups to enable the feature. Why: This follows the principle of least privilege, allowing for granular rollouts without altering user profiles. **Validate in Code (The Gatekeeper):** Apex: Use FeatureManagement.checkPermission('FEAT_NewDashboard') to check if the user has the permission. Lightning Web Components (LWC): Use @salesforce/customPermission/FEAT_NewDashboard to hide/show UI components. Flows: Use a Decision element to check if the user has the Custom Permission. **Enforce Data Security (Backend Control):** Use WITH USER_MODE in SOQL queries or Security.stripInaccessible() to ensure that even if a user bypasses the UI, they cannot see or modify data they are not allowed to.

The original FAQ content is technically accurate and well-structured. I made minimal formatting improvements for better readability by adding bold headers and improving the structure slightly, but preserved all existing points and information. No outdated content was detected as the recommendations align with current Salesforce best practices. For security rules selected: 1. ApexCRUDViolation - This rule is directly relevant because the FAQ discusses using WITH USER_MODE in SOQL queries and Security.stripInaccessible() in the 'Enforce Data Security (Backend Control)' section. These are precisely the mechanisms that help avoid CRUD violations by ensuring proper field-level and object-level permissions are enforced. 2. ApexSharingViolations - This rule applies because the FAQ mentions using USER_MODE database operations and Security.stripInaccessible() which are key methods for ensuring sharing rules are properly enforced when accessing data, preventing unauthorized access to records based on sharing settings.
