Even when a company is doing things pretty well with a VPN, all it takes is one mistake and the cat is out of the bag. At one of my previous employers, we had a fairly good setup with VPNs using single sign on via our IdM provider. IdM enforced SSO and the VPN had a number of policies setup which kept good control over what users could login. And then someone had the brilliant idea to take an old VPN appliance, reset it to factory defaults and configure it just enough to work on our network and then hung it out on the internet for some sort of test (our configuration management left a lot to be desired). Of course, that led to it being left there for a couple months and an attacker finally found it. They also had a valid username/password combination which got them in the door.
Security is hard and often expensive. But still, compared to “we put out OT devices on the internet” a basic VPN is a huge step up.
















Why do I hear singing, and what are those ships on the horizon? I can’t seem to make out their flags, they all just look black to me.
