  1. SSL/TLS and Encryption

• Ensure proper configuration and renewal of the Domain Certificate.
• Strengthen Ciphers by using modern, secure algorithms and disabling outdated ones.
• Enforce support for secure TLS Versions (1.2 or higher), deprecating older, vulnerable protocols.
• Implement HTTP Public Key Pinning (HPKP) (though deprecated, use cautiously in legacy systems).
• Configure a robust HSTS policy to enforce HTTPS connections and protect against downgrade attacks.
• Implement a seamless HTTP to HTTPS redirect across all resources.
• Perform DANE scan and activate DNSSEC to enhance DNS query authenticity and integrity.
• Ensure full deployment and maintenance of DNSSEC for all relevant domain records.

   

2. Cookie and Session Security

• Set the HttpOnly flag for cookies to prevent client-side scripts from accessing session data.
• Harden cookie security by enforcing secure attributes and proper expiration settings.
• Review and optimize cookie handling practices, ensuring secure storage and transmission. 

3. Header Security Policies

• Add the X-Content-Type-Options header to prevent MIME-type sniffing.
• Configure the Referrer-Policy header to control the information shared via the referrer field.
• Use the X-Frame-Options (XFO) header to protect against clickjacking attacks.
• Implement X-XSS-Protection (though largely deprecated, as CSP is preferred for XSS mitigation).
• Enforce a strict Content-Security-Policy (CSP) to mitigate cross-site scripting (XSS) and data injection vulnerabilities.

4. Cross-Origin and Subresource Integrity

• Configure Cross-Origin Resource Sharing (CORS) to restrict resource sharing with only trusted origins.
• Utilize Subresource Integrity (SRI) to ensure integrity of external resources like JavaScript and CSS.

5. DNS and Routing Security

• Ensure the Subnet for name server is correctly configured and secured.
  Validate Route announcement validity (ROA) to protect against BGP hijacking and misrouting.
• Configure and validate SPF records to reduce email spoofing and ensure domain protection.
• Add support for IPv6 addressing to future-proof the web server and ensure compatibility.

6. Vulnerability and Version Control

• Regularly scan for and patch server-side vulnerabilities, ensuring all components are up-to-date.
• Mask version identifiers of server software to reduce information leakage and exposure to targeted attacks.

7. Security Standards and Documentation

• Publish a security.txt file to provide security researchers with the appro
