SSH the admins are sleeping…

Jeremy Stott

Have you ever wanted to know more about SSH authentication than you have ever wanted? Then this course is for you! We will learn all the wonderful secrets of secure shells together without waking the admins (I don’t know where I was going with this analogy, but it made a good title).

There is the humble password authentication method, public/private keys, hardware security keys, smart cards, agents, certificates, donuts, certificate authorities, TOTP, multiple authentication methods, FIDO2, sudo with certificates, and more (probably, maybe).

Often forgotten, and in my opinion one of the bigger challenges, is authorization. Sure you have a users public key, but how do you manage exactly which machines they can access and which they can’t?

If you are an administrator, you might learn practical ways to improve your SSH setup for your users.

If you are a user, you might learn practical ways to improve your SSH setup for your administrators ;)


Learn about advanced SSH authentication methods, that are not really that scary and super cool.

Learn how to improve the security of their own SSH setups.

Get angry at apple for not compiling their bundled version of OpenSSH with hardware key support (shakes fist).
