With organizations across the globe bracing themselves for a second wave of ransomware attacks, the impact of Friday’s WannaCry attack is still being counted. With over 150 countries impacted, this attack has caused massive disruption for organisations including telecoms companies, car manufacturers and in the UK, the NHS has been significantly impacted with IT systems shut down and operations cancelled.

This attack quickly proliferated across IT systems through an identified vulnerability in Microsoft Windows. Microsoft said it had released a security update in March to address this, but many organizations were yet to run it(1). With IT teams working throughout the weekend to shore up their security and increase defences against further attacks, what can organizations do to stop ransomware and malware attacks from propagating across their IT systems?

Doing nothing is not an option.
