The number of cyber attacks happening every year is on the rise. We speak to Bruce Schneier, chief technology officer at the IT company Resilient Systems and a fellow at Harvard's Berkman Center for the Internet and Society, about why it can take months before a company or organisation even realises it is under attack, and why so many are unprepared. Also, Wil van Gemert, deputy director of operations at Europol, tells us what European law enforcers are doing about it. He says it is now possible to buy 'malware', or malicious software meaning that anyone can become a cyber criminal. Carl Leonard, principal security analyst at Websense, says security issues are only going to become more urgent as the internet-of-things develops. Once everyday items such a fridges and cars are connected online, we will become ever more vulnerable.

And, our regular commentator Lucy Kellaway of the Financial Times tells us why companies score so badly on giving constructive feedback to employees.
