Just one per cent of security spending goes on training and human factors, says Melanie Oldham.

Oldham is the founder of Bob's Business. Her security training company is best known for the eponymous Bob, a put-upon business exec who battles to secure his operation.

But Bob is not alone. This industry, Oldham argues, needs to strip away the complexity that too often surrounds cyber security.

And we need to focus less on hardware and technology, and more on the people who handle data. Non-technical users often make the best security champions. That, she says, will only be more important, as remote working becomes the norm.
