FAQ-001584 - SQL Injection and Input Validation / Application-Level Security Concerns

Acceptable approaches for handling user-generated query conditions include: 1. **Use Bind Variables**: Prevent input from breaking out of its quoted context by using bind variables. 2. **Sanitize Input**: If bind variables can't be used, sanitize input with methods like `String.escapeSingleQuotes()` for simple string comparisons. Combine this with other validation techniques to handle all potential harmful input. 3. **Avoid System Mode Execution**: Don't execute user-generated queries in Apex system mode. 4. **Use APIs for Complex Queries**: For more complex client-side SOQL, use the REST or SOAP API to ensure safe execution. 5. **Validate Permissions**: Always validate user permissions for objects and fields before executing queries. These practices help ensure secure handling of user-generated query conditions.

The content is accurate and current. I made minor improvements to make the language more conversational and direct by changing 'Do not execute' to 'Don't execute' to align with the brand guidelines for conversational tone. The FAQ covers essential security practices for handling user-generated query conditions. For the related security rules: - ApexSOQLInjection: This rule directly relates to points 1 and 2 in the FAQ which discuss preventing SOQL injection through bind variables and input sanitization, which are the core techniques for preventing SOQL injection attacks when handling user-generated query conditions. - ApexCRUDViolation: This rule relates to point 5 which discusses validating user permissions for objects and fields before executing queries, as CRUD violations occur when proper object-level permissions aren't enforced. - ApexSharingViolations: This rule relates to point 3 about avoiding system mode execution and point 5 about validating permissions, as sharing violations can occur when queries bypass user-level sharing rules through system mode execution.
