Why multi-layered security is still the best defence

Abstract

As if protecting resources in the age of Bring Your Own Device (BYOD) wasn't already hard enough, the beleaguered, unsung heroes of corporate IT security increasingly have to look beyond the plethora of user-access devices and consider the security of equipment such as printers, fax machines, and even the routers and switches with which the network is built. As if protecting resources in the age of Bring Your Own Device (BYOD) wasn't already hard enough, the beleaguered unsung heroes of corporate IT security increasingly have to look beyond the plethora of user-access devices and consider the security of equipment such as printers, fax machines and even routers and switches. The notion of a multi-tiered defence has somewhat gone out of fashion. However, corporate networks are becoming more complex and the nature of the threats is evolving. Simon Denman of NETASQ looks at the current threat landscape and argues that a multi-layered defence is still the best way of securing the corporate network.
