Abstract:

This paper explores the shift toward cloud-based information technology (IT) solutions and the evolution of security concerns through this shift. Insights into what is driving the growth of public cloud solutions will help organizations to develop a comprehensive approach to securing their information systems. The introduction of cloud computing models to enterprise environments poses a fundamental challenge to traditional Information Technology (IT) concepts of the network perimeter, information control and data governance. These traditional environments include multi-layered security that protects the information by establishing perimeter defenses incorporating Firewalls, Routers, Anti-Virus gateways, Intrusion Prevention and encryption gateways for remote virtual private network (VPN) connectivity. However, in recent years these traditional boundaries have become less defined. There are a number of disruptive technologies that have driven this including social networking, mobile computing and most directly cloud computing. In addition, the sophistication of threats and the number of devices connected to the Internet have increased substantially. Organizations can no longer assume trust for users within the perimeter. Rather the traditional defense tactics leveraged by enterprise organizations need to incorporate new information-centric approaches to their overall cyber security strategies. This paper explores some of these new security paradigms and the sources of them. It pries open the current trends driving growth in cloud services and proffers recommendations for integrating them into enterprise security methodologies.
