What happens to cybersecurity when remote office workers become home workers, connecting to remote customers who are themselves working from home? VPNs are not the solution. Zero trust networks are.
National security agencies and the military know that there is only one sure way to protect an IT device from malware, and that is to isolate it completely. “Air gapping”, rather than networking, means that there is no room for connections to allow malware to spread between devices. Unless, of course, some malicious or fallible human carries it over – but that is another story.
Humanity is currently threatened by its own version of malware – the coronavirus. Scientists have advised governments that humans must be “air gapped” to reduce the risk of it spreading. The tactic is to enforce social isolation via lockdown. Office workers, for example, must now work from home – and phone, social media, messaging and conference calls have replaced the business meeting, the open-plan office, the family reunion or friendly handshake.
The irony is this: now that people are (relatively) safely air-gapped, the attack surface across their means of communication systems has ballooned. Consider an online financial transaction: this process would normally entail a call via the office through to the financial services company or its helpdesk. But under lockdown, the office worker is now calling from home, and the finance staff are also working from home.
How can we ensure edge to edge security when the edge can be anywhere?
The Virtual Private Network (VPN) is not up to the task
There used to be a sure way to connect branch offices to headquarters: you lease a private line between them. As a dedicated private line, it was intrinsically “air gapped” from other communication lines and so very secure. But it was a costly solution, requiring manual connection at either
