What security considerations should be taken into account when choosing between JavaScript, AJAX, Flash, and Java for game development?

When choosing between JavaScript, AJAX, Flash, and Java for game development, security considerations are crucial. JavaScript and AJAX are more secure as they run within the browser sandbox and have limited access to the user's system. Flash and Java, on the other hand, have a history of security vulnerabilities and may pose a higher risk if not properly secured. 

// Example of implementing security considerations in JavaScript for game development
<script>
    // Ensure all user inputs are properly validated and sanitized to prevent XSS attacks
    function validateInput(input) {
        return input.replace(/<[^>]*>/g, '');
    }
    
    // Use HTTPS for all communication to prevent man-in-the-middle attacks
    if (window.location.protocol !== 'https:') {
        window.location.href = 'https:' + window.location.href.substring(window.location.protocol.length);
    }
    
    // Implement content security policy to prevent injection of malicious scripts
    document.headers['Content-Security-Policy'] = "script-src 'self'";
</script>
