Enterprise security and privacy: Why adding IoT and big data makes it so much more difficult

Achieving enterprise security is a huge challenge, which becomes much more challenging when cloud is added to the mix, due to the multi-tenancy nature of cloud ecosystems. Once we add the dimensions of the Internet of Things (IoT) and Big Data, this problem becomes exponentially more complex. We consider why this is so and highlight a number of key research questions which have yet to be resolved. We seek to address the problem by combining a number of emerging research techniques which we and our collaborators have developed, in such a way as to improve the chance of achieving a better level of security and privacy for enterprises.
