Backup Communication Channels

IT Leadership, , , ,

What is the difference between 30 individual soldiers and a platoon? Leadership and the ability to communicate.

The first step in your resilience planning is to ensure that you can still communicate, even when faced with an onslaught of Russian hackers or American government officials.

That could mean an on-premise open source mail server and a basic web server. Every workstation and company smartphone could have a separate open source mail client and web browser preconfigured for those servers.

There are many other options – the paranoid and those with high threat levels might have spare phones running GrapheneOS and Briar, or even establish their own Meshtastic mesh network.

If you don’t have a backup communication channel, you urgently need to establish one. Especially if you are outside the U.S. and depend on U.S. services.

Are You Sure Your Backup System Works?

Why did all the trains in Denmark stop on Saturday? Russian hackers may or may not have been involved, but Danish incompetence was.

The Danish State Railways (DSB) has digitized all the paper that a train driver used to carry. That’s temporary speed restrictions, track works, and deviations from the standard schedule. They have also outsourced their digital solution to an amateurish vendor, and neither the vendor nor DSB had a backup solution. So when the vendor shut down the system due to an unspecified “security issue,” the trains stood still.

I’ve boarded a Delta Airlines flight with a hand-written boarding card on a scrap of paper. A professional organization continues to run, though slower, without its computers. An unprofessional organization like DSB is paralyzed. Are you like Delta Airlines or like the Danish State Railways?
