Collection of HTTP and HTML metadata information in order to categorize its relevance as a sign of possible security weakness or signs of hardening in any website. The final goal is to raise web security awareness (assessing favourably the signs of hardening and assessing negatively the signs of weakness) with an overall interpretation of this information from any website.

Examples of Metadata assessing
Weakness signs Hardening signs
