Implement X-Frame-Options and X-Content-Type-Options Security Headers

# In your Nginx server block or http block
# Protect against Clickjacking attacks
add_header X-Frame-Options "DENY"; # Other options: "SAMEORIGIN", "ALLOW-FROM uri"

# Protect against MIME-sniffing vulnerabilities
add_header X-Content-Type-Options "nosniff";

# Optional: Enable for all responses, or specific locations
# For example, to apply globally:
# server {
#     listen 80;
#     server_name example.com;
#
#     add_header X-Frame-Options "DENY";
#     add_header X-Content-Type-Options "nosniff";
#
#     location / {
#         # ... your application specific config
#     }
# }

How it works: This Nginx configuration snippet adds two important security headers. The `X-Frame-Options "DENY"` header prevents your website from being embedded within an `<frame>`, `<iframe>`, `<embed>`, or `<object>` tag on another domain, effectively protecting users from clickjacking attacks. The `X-Content-Type-Options "nosniff"` header prevents browsers from "sniffing" a response's content type away from the declared `Content-Type` header, which can prevent certain XSS attacks that arise from misinterpretation of file types. These headers are simple yet powerful additions to enhance web application security.
