Security in Secure Custom Fields

Security is a core principle of Secure Custom Fields. This guide explains our security practices and how to implement them in your projects.

Core Security Principles

1. Input Validation
   • All user input is validated
   • Type checking enforced
   • Sanitization applied appropriately
2. Output Escaping
   • Context-aware escaping
   • HTML, attributes, and URLs handled separately
   • Custom escaping functions for specific needs
3. Capability Checking
   • Granular permission system
   • Role-based access control
   • Custom capability support

Best Practices

When working with SCF:

1. Always use provided escaping functions
2. Check user capabilities before operations
3. Validate all data before saving
4. Use nonces for form submissions
