The Cloud Security Survival Guide

For companies increasingly dependent on cloud services, security challenges abound. Here's a collection of articles, columns and audio to help IT security practitioners plot the right course.

Virtualization and cloud computing let you simplify your physical IT infrastructure and cut overhead costs, but you've only just begun to see the security risks involved. Putting more of your infrastructure in the cloud has left you vulnerable to hackers who have redoubled efforts to launch denial-of-service attacks against the likes of Google, Yahoo and other Internet-based service providers. A massive Google outage earlier this year illustrates the kind of disruptions cloud-dependent businesses can suffer.

But since the benefits of cloud services are so robust, there's really no turning back. The key is for companies to be made aware of the risks and to have some security best practices to live by.
