Hello, welcome to the Thursday, February 23rd, 2017 edition of the Sansanet Storm Center's Stormcast. My name is Johannes Ulrich, and today I'm recording from Scottsdale, Arizona.

Netflix made yet another interesting security tool open source. This security tool focuses on mobile device management. What it is, it's

0:23.6

a web application that your users can use to review their devices security posture. It

0:30.6

does integrate with a number of different mobile device management systems. So if your user is connected to one of these

application, so it shouldn't really be that terribly difficult to install for anybody.

1:51.6

And then we got yet another interesting blog by Alexander Klingk, this time about how

Firefox uses intermediate certificate authority certificates.

2:01.6

The problem here is that if you go to an HTTP website, what you usually receive from the website is the website certificate

2:09.6

and the signing certificate that was used to sign this particular website certificate.
