CASB - Cloud Access Security Broker

Abstract

With cloud technology becoming a larger and more important part of running a digital business, cloud computing platforms are rapidly limiting the effectiveness of the traditional security model. The cloud has required organizations to rethink security. Since data and applications in the cloud reside outside the old enterprise boundaries, they must now be protected in new ways. As more and more users connect directly to public cloud applications, and as workloads continue to shift to leverage Infrastructure-as-a-Service and Platform-as-a-Service capabilities from providers, a category of products called Cloud Access Security Brokers (CASB) has emerged to prominence and has become the go-to solution to address challenges in cloud security. Over the years, CASBs have evolved to keep pace with the rapid cloud adoption trends. This paper is an attempt to define some of the key capabilities that organizations look for in a CASB solution.
