Wrapping Your Arms Around Cloud App Security

There's nothing worse than a leaky cloud. If you are talking literally about the sky you get soaked. If you are being metaphorical and referring to computing, your leaking cloud means lost data and break-ins. Neither are good, but I'd much rather have to towel off.

Like raincoats and umbrellas, there are ways to protect your cloud apps.

Peter Silva, a manager with F5, wrote a piece for Virtualization Review explaining how to secure cloud software when you don't have control over the physical network, such as the ability to deploy what is now a sumptuous array of security appliances.

Since the cloud is virtual, you yourself have to go virtual such as using virtual Web firewalls rather than the ones you actually put in a rack, hook to the network, and tie to Consolidated Edison.

What's cool about these Web-based firewalls is you can set 'em so easily. With a physical firewall you set it up assuming a need and hoping it fully works.

With virtual, if you spot a cloud application vulnerability -- say there is a security alert -- you can quickly deploy the firewall. This way, your cloud app can be proactively and reactively protected.
