When we talk about security, we often talk about the “assume breach” scenario and therefore about resilience against attacks. When I am on panels talking about resilience, I often talk about resilience in society as well.
Today, large parts of Zurich were without power for one hour. It is interesting to see what happened: Shops needed to be closed (the revolving doors did not work anymore, cash registers did not work, etc.), traffic lights stopped working (the police had to look after critical crossings), trams stopped running etc. In our offices, obviously lights did not work anymore but the wireless and the Internet connection still worked – but for how long? Worst thing: The coffee machine had no power as well!
But then you look into the next steps. You do not know how long it lasts, so how long is the battery on your notebook working? We have a call this afternoon, will we need to find another location to make sure we can take it? Starbucks around the corner is not optimal, as they do not have power either… And how do you get home? Remember the trams… but the trains are running on a different power grid.
After an hour, everything is back.
But think resilience: What would happen if the power outage would be longer? The mobile network will eventually switch off as well as will the Internet connection. How resilient is your business to such an outage? How resilient are you as a person?
Predictions for 2016 say that we will get answers to this question some when this year due to an attack on a critical infrastructure even in Europe as it happened in Ukraine last December.
