Large scale study of SSL configurations

Ivan Ristic is the director of engineering at Qualys and principal author of ModSecurity, the open source web application firewall.

In this podcast, Ivan talks about the Qualys SSL Labs Internet-wide SSL survey and their recent release of the raw data from the survey.

The raw data contains the SSL assessment results of about 850,000 domain names. The main file (120 MB compressed, 800 MB uncompressed) is a dump of the PostgreSQL database in CSV format. Included in the download is a simple PHP script that iterates through all the rows, which means that you can consume the data directly. Alternatively, you can put the data back into the database and use SQL to run ad-hoc queries (we provide the schema along with the import instructions).
