It was observed that, application was not sending security directives to the client like X-XSS Protection, HSTS (HTTP Strict Transport Security), Content Security Policy, X-Content-Type-Options.

1. Content Security Policy: The content-security-policy HTTP header provides an additional layer of security. This policy helps prevent attacks such as Cross Site Scripting (XSS) and other code injection attacks by defining content sources which are approved and thus allowing the browser to load them.

2. X-XSS Protection: The X-XSS-protection header is designed to enable the cross-site scripting (XSS) filter built into modern web browsers. This is usually enabled by default but using it will enforce it. It is supported by Internet Explorer 8+, Chrome, and Safari.

3. HTTP Strict Transport Security (HSTS): The strict-transport-security header is a security enhancement that restricts web browsers to access web servers solely over HTTPS. This ensures the connection cannot be establish through an insecure HTTP connection which could be susceptible to attacks.
