Future internet environment is affected by permanent and rapid changes, triggered by the emergence of high bandwidth-demanding services, applications, and contents. Cloud computing might be considered as the prelude of the future internet. Additionally, the concept of elastic optical networks is a widely accepted promising solution for the future internet. This chapter addresses the security aspects of the content provisioning process with cloud migration over elastic optical networks in the future internet environment. Key characteristics of the cloud computing and elastic optical networks relevant to the content provisioning process are presented. Major threats in each segment of the observed process, including vulnerabilities in the cloud computing and security issues in elastic optical networks, are considered.
