What should replace ESAPI for input validation and output encoding in modern Salesforce development?
Answer
In modern Salesforce development, ESAPI should be replaced with Salesforce's built-in encoding functions for output encoding, such as:
- **JSENCODE**
- **JSINHTMLENCODE**
- **HTMLENCODE**
- **URLENCODE**
For input validation, you can use methods like **String.escapeSingleQuotes()** to sanitize user input and ensure proper validation mechanisms are in place. Additionally, apply context-based escaping based on the specific use case.

Reasoning
The FAQ content is accurate and provides good guidance on replacing ESAPI with modern Salesforce encoding functions. I made a minor formatting improvement by removing extra blank lines to make the content more concise while preserving all the information. The three security rules I selected are directly relevant to this FAQ's content: ApexXSSFromEscapeFalse relates to XSS prevention through proper escaping (which the FAQ addresses by recommending encoding functions like HTMLENCODE and JSENCODE), ApexXSSFromURLParam relates to XSS prevention from URL parameters (which the FAQ addresses through input validation recommendations like String.escapeSingleQuotes()), and VfUnescapeEl relates to proper escaping in Visualforce (which the FAQ addresses by recommending context-based escaping and built-in encoding functions). All three rules focus on preventing XSS vulnerabilities through proper encoding and escaping, which is exactly what this FAQ teaches developers to implement as ESAPI replacements.
