There is a view of the current security market that is often recycled by the media these days. It assumes a split between ‘first-gen(eration)’ or ‘traditional’ (or even ‘fossil’ or ‘dinosaur’) malware detection technology – which is invariably claimed to rely on reactive signature detection – and (allegedly) superior technologies using ‘next-gen(eration)’ signature-less detection.
This picture is much favored by some ‘next-gen’ companies in their marketing, but it doesn’t reflect reality.
