Take Friday’s IT nightmare as a warning of what a cyberattack could do

The global Microsoft computer outage initiated by a faulty CrowdStrike security update gave us a taste of what actual cyberwarfare could do.

That shut down or crippled airports, hospitals, stock exchanges, banks and media from Europe to America and on to Australia and India — as well as government agencies including the Homeland Security Department and the Cybersecurity and Infrastructure Security Agency.

Cue the rush to put everyone’s cyber-eggs in a lot more baskets.
