Overview: Cloud computing has become another key resource for IT deployments, but there is still fear of securing applications and data in the cloud. These concerns include authentication, authorization, accounting (AAA) services; encryption; storage; security breaches; regulatory compliance; location of data and users; and other risks associated with isolating sensitive corporate data. Add to this array of concerns the potential loss of control over your data, and the cloud model starts to get a little scary. No matter where your applications live in the cloud or how they are being served, one theme is consistent: keeping that data safe is a top priority.
This paper looks at strategies that can help make your cloud infrastructure or deployment more secure, reliable, and resilient. Secure remote access technology provides contextual, secure access to cloud-based applications; web application firewalls provide the means to centralize application security; network-side scripting offers an agile, immediate method of addressing security vulnerabilities on an on-demand basis, all helping to keep the cloud dynamic, fluid and secure. The paper also explains how IT administrators can isolate configuration and management for fine-grained control over access to cloud computing infrastructure and can isolate application traffic for improved security of application data that uses shared resources.
