FAQ-001592 - SQL Injection and Input Validation / Dynamic SOQL Query Construction

The recommended approach to secure dynamic queries based on user input is to: 1. **Use Bind Variables**: Incorporate bind variables in your SOQL/SOSL queries to safely include user input and ensure it's treated as data, not executable code. 2. **Sanitize String Inputs**: Apply `String.escapeSingleQuotes()` to sanitize user-provided string data and prevent it from breaking out of its quoted context. These practices help prevent SOQL injection vulnerabilities by ensuring user inputs are properly escaped and do not alter the intended query structure.

The FAQ content is accurate and well-structured, addressing the critical security concern of SOQL injection prevention in dynamic query construction. I made one minor terminology improvement by changing 'injection vulnerabilities' to 'SOQL injection vulnerabilities' to be more specific about the type of vulnerability being prevented, which aligns with Salesforce-specific security terminology. I selected the ApexSOQLInjection rule because this FAQ directly addresses SOQL injection prevention techniques. The FAQ's content about using bind variables and String.escapeSingleQuotes() method directly relates to preventing the security vulnerabilities that this rule detects. The FAQ teaches developers how to avoid the exact security issues that ApexSOQLInjection rule flags - specifically the improper handling of user input in dynamic SOQL queries that could lead to injection attacks.
