Automated testing of SSL security / 2014-10-29

2014-10-29 Automated testing of SSL security 5 years ago
As part of my job I write down security requirements in new projects. Those include 'connections between systems that transport non-public data need to be encrypted using up-to-date encryption'. At the same time, work is improving their testing procedures so new or upgraded applications come to production fully tested according to predefined testing scenarios. So now 'security' is also part of the test scenarios and I was asked to help build tests for our security requirements.

For secure websites it is easy, I use the Qualys SSL Labs SSL Server Test. But there are a lot more ssl secured connections in use, and I would like those verified too without having to expose them to the outside world. Preferably both from Unix and Windows endpoints. And automated and/or as a scenario that can be done by the responsible system administrators.

A simple websearch gave no answers but some asking around gave me SSLScan for Windows which is a windows port of SSLScan Fast SSL Scanner. It's even free, and it gives out just the reports I want:

At this moment it complains about a self-signed certificate because I haven't given it a list of root certificates. I can't find out at the moment how to fix that, it doesn't seem to check the list of root certificates or not in a place I put them.
