WannaCry: What can you do to protect your business?


The WannaCry cyber-attack infected more than 200,000 computers in 150 countries, affecting government, healthcare and private company systems. But how easily could it have been avoided and how can firms protect themselves against future attacks?
On the face of it, the accepted narrative seems simple. Microsoft issued a patch, or update, for the vulnerability in its older Windows operating systems in March.
If all IT departments everywhere had implemented this patch immediately, the WannaCry ransomware worm wouldn't have been able to run riot across the globe.

He says: "There are a lot of practical challenges in deploying patch updates; from having unsupported operating systems [OSs] that don't have patches available, through to the practicalities of rolling out sweeping changes across massive networks, potentially globally.
"But these aren't new challenges - anyone running these networks should have had this solved long before now.
