FAQ-000090 - Access Control and Authorization Issues / AppExchange Security Compliance

To implement permissions and access control for AppExchange security compliance, follow these guidelines: 1. **Audit Access Control Changes and Misconfigurations**: Define sharing and org-wide default configurations for custom objects in managed packages. Restrict functions that modify sharing or access control to users with specific permissions, and review them for compliance. 2. **Permission Set and Profile Modifications**: Limit changes to user permission sets, profiles, and custom/manual sharing of objects to specific entry points. Verify the caller's user context permissions for these actions. 3. **Use OAuth Credentials**: Avoid handling user credentials or impersonating users in managed packages. Instead, use your own OAuth credentials for authentication. 4. **Custom Apex Sharing**: Ensure custom sharing logic explicitly defines access levels and applies sharing only to authorized users or groups. 5. **Code Review Responsibility**: Security review teams should verify that permissions are checked against the caller's context and flag any non-compliant use cases. By adhering to these practices, your solution can meet the security requirements for AppExchange compliance.

The FAQ content aligns well with AppExchange security requirements and doesn't require significant changes. The answer is clear, well-structured, and covers the essential aspects of permissions and access control. No outdated content was detected. For the security rules selected: - **ApexSharingViolations**: Directly relates to point #4 about "custom sharing logic" and point #1 about "sharing and org-wide default configurations." This rule detects sharing violations in Apex code, which is exactly what the FAQ discusses when mentioning custom sharing logic and access control configurations. - **ApexCRUDViolation**: Relates to point #5 about "permissions are checked against the caller's context" and the overall theme of access control implementation. This rule checks for proper CRUD permissions in Apex, which aligns with the FAQ's emphasis on verifying caller permissions. - **AvoidGetInstanceWithTaint**: Connects to point #3 about "avoid handling user credentials or impersonating users" as this rule prevents unsafe user impersonation patterns that could bypass access controls. - **AvoidUnauthorizedApiSessionIdInApex** and **AvoidUnauthorizedGetSessionIdInApex**: Both relate to point #3 about proper authentication practices and avoiding credential handling, as these rules prevent unauthorized session access that could compromise access control. - **AvoidHardcodedCredentialsInFieldDecls**, **AvoidHardcodedCredentialsInVarAssign**, **AvoidHardcodedCredentialsInVarDecls**, and **AvoidHardcodedCredentialsInHttpHeader**: All relate to point #3 about "avoid handling user credentials" by preventing hardcoded credential patterns that could bypass proper access control mechanisms.
