About this recipe

HTTP headers are vital for enhancing web application security. Here are key ways they can be used:

- Content Security Policy (CSP): Specifies trusted sources for dynamic resources, preventing Cross-Site Scripting (XSS) attacks.

- HTTP Strict Transport Security (HSTS): Enforces HTTPS connections, protecting against SSL stripping and man-in-the-middle attacks.

- X-Content-Type-Options: Prevents MIME-sniffing, reducing the risk of drive-by download attacks by setting it to "nosniff".

- X-Frame-Options: Controls page rendering in frames, helping to prevent clickjacking attacks.

- Cross-Origin Resource Sharing (CORS): Manages how resources can be accessed from different domains, preventing unauthorized access.

- X-XSS-Protection: Enables browser XSS filters to block reflected XSS attacks.

- Identifying Outdated Software: Reveals server software versions, helping to identify potential security vulnerabilities from outdated software.
