Live today Some vendors will tell you that security problems are solved by sticking a device on the edge of your network, but we all know that 100 per cent security is a fantasy.

You will be attacked by both known and unknown threats, and some of those attacks will be successful. This means that recognising the signs of an attack quickly – and being able to limit the effect on your business when those attacks succeed – is fundamental to your security policy.

Raimund Genes from Trend Micro will be in the studio to describe the nature of threats today and how we should be managing them. He's joined by The Dark Lord, Tony Lock, who returns to the studio to fill us in on how the Reg audience is coping with the known unknowns of security.

Whether it's a Magic Kitten or the Second Bureau of the People's Liberation Army's General Staff Department's Third Department which is attacking you, it is how you protect yourself that counts.

Join us live today at 13:00 BST for this Regcast, to see how our experts can help you survive the attack of the known unknowns.
