Growth of cloud services has ushered in a new computing architecture and, with it, a host of security challenges. Three such challenges include governing usage; protecting sensitive data and preventing its loss; and defending against threats that propagate in the cloud. Unlike traditional computing architectures in a corporate network - for which security solutions have been designed — cloud services enable security violations and threats to fly under the detection radar. This is partly because many cloud services are unknown to corporate IT and information security teams, but it is also because cloud traffic secured by the SSL (or the more generic TLS) encryption protocol often goes unmonitored by enterprises.
