This is a continuation of work started by Brough Davis as part of his software security project for his Masters in Information Security Engineering. The main goal of this project is to find how many sites use security relevant headers, like for example the X-XSS-Protection or X-Frame-Options headers.

Below you will find a table/histogram showing how many times we found each header (security relevant or not). We access the index page of each site using a "head" request. The list of sites is derived from Alexa's Top 1 Million sites. We try to poll as many sites as possible each day.

As we collect more data, we will plot changes over time.
