"A lot of people will claim that the cloud is fundamentally insecure," he says. "The real issue is not security, it's more about control and visibility. It's a trust issue. Salesforce and Google need to have good security. From a security standpoint, they're going to be much better than most companies."
The problem, Popp says, is that organizations don't have a good mechanism for injecting their own security policies into cloud services and they don't have the ability to access logs.
"The issue is that the cloud guys do not provide IT with enough control to set their own policy," he says. "It's actually difficult because every cloud is different. You have different APIs and security frameworks. They're all going to have different ways to do security and expose that security. We need to create a new control point so IT can inject their own policies on top of these cloud services."
Additionally, he says, an organization's IT staff needs to have access to logs and backups for both regulatory compliance and the capability to perform forensics if something does get compromised.
Symantec's answer is O3, a cloud information gateway that it likens to the earth's ozone layer. It's intended to sit between an organization and its cloud services and act as a sort of cloud firewall. Popp says it will provide three layers of control: an identity and access control layer, an information protection layer and an information management layer. The first layer provides role-based access to information in the cloud, while the second enforces and organization's security policy. The final layer will capture all the logs and allow organizations to demonstrate regulatory compliance.
PerspecSys takes another tack, though like Symantec it focuses on the message of control.
"We make cloud applications mission-critical for companies by ensuring that their sensitive data never moves outside the company's network," explains Canellos. "We help you use the application in the cloud, but keep the sensitive data behind your firewall at all times."
PerspecSys focuses on protecting data in flight with an approach that Canellos says helps reduce the risk of data transfer, data processing and storage in the cloud.
"If you talk to data centers or the cloud providers, when the data is under their control, within the perimeter of their data center, they can give you all the assurances that the data is probably more secure than if it is with the perimeter of an SMB network," he says. "But what happens when the data is in flight? At that point, if you look at the agreements companies have with data centers, that is no longer their responsibility."
The PerspecSys Cloud Control Gateway uses tokenization to replace sensitive data in the cloud.
