De-Perimeterisation: Benefits and limitations

De-Perimeterisation is a new term to describe phenomena becoming common in modern ICT environments. It refers to the erosion of the hard-shell model used to describe the structure of traditional information security implementations while capturing the growing requirement for perimeters to be breached in order to facilitate commerce and collaboration. The Jericho Forum, formed by a group of leading information security managers, has started an exploration of De-Perimeterisation concentrating on identifying its scope and creating working groups to study and specify requirements. This paper, after a review, discusses the benefits and the limitations of this approach.
