How The Principles Of Disaster Recovery Can Guide Us With Cyber Resilience
SC Media, Friday, January 16th, 2026
Cyber resilience often gets treated as a new challenge driven by modern threats. It isn't. We solved a version of this problem decades ago in disaster recovery. The lessons still apply.
Early in my career, I worked with IBM mainframe customers running high-availability systems. Downtime wasn't acceptable. Failure was assumed. So they practiced for it.
They intentionally failed over from one data center to another every month or every quarter. Not because something was broken, but because they needed proof that recovery worked. Repetition built confidence. Teams didn't debate during an outage. They executed and they trained like they fought.
