Public Cloud Too Public?
Addressing security concerns of the Public Cloud
Enthusiasm for cloud computing has as much to do with economics as technology. Growth in the number of applications and the volume of data that must be managed have made datacenters a major item of corporate expense. Public cloud computing looks like a way to get a handle on some of these costs.
The concept of cloud computing is straightforward: you replace capital-intensive IT assets that must be internally managed with rented “pay-as-you-go” IT capacity and services at commoditized prices. These services are built with new technologies such as virtualization and service-oriented architectures and leverage the Internet to reduce the cost of IT hardware and software resources for computing, networking and storage. At the same time, enterprises are using the same concepts and technologies to build out private clouds to capitalize on centralized, commoditized IT services that meet their security needs.
Today, both public and private cloud deployments must embody an appropriate set of core security principles and thereby assure users and customers of a trustworthy cloud-computing environment.
The main issues with Cloud Security
For many CIO’s today, the perceived barriers to Cloud computing remain security, regulation and compliance amongst others.
Organizations seek reassurance on several points: accessing the Cloud will not compromise their security; their sensitive data and intellectual property will be protected; they can retrieve their data if they want to change their current Cloud provider, or their provider winds up operations; and they can maintain their customer service standards and competitive performance.
CIO’s 2011 Global Cloud Computing Adoption survey reveals that 56% of the IT and business leaders say managing access to data in the cloud is a top challenge. With the quantum of data being generated, the number of identities and devices accessing the cloud, and the ever-changing infrastructure, these leaders recognize that today, they may not have the needed controls and lack ￼real-time visibility. They can’t manage what they can’t see and they can’t secure what they can’t manage. Many organizations have siloed environments that are complex and difficult to manage. In such organizations, the dynamic nature of cloud environments, where data and applications move about at a moment’s notice only add to the complexities. However, for organizations with siloed environments, starting with a foundation of virtualization before moving on to the cloud will provide greater visibility than legacy approaches….
