Hybrid cloud should strengthen your organization’s security posture, not diminish it. But that doesn’t mean improved security is a default setting. While security fears are declining as cloud matures, security remains an ongoing challenge that needs to be managed in any organization. And a hybrid cloud environment comes with its own particular set of security considerations.
1. Ensure you have complete visibility.
Too often in modern IT, CIOs and other IT leaders have blind spots in their environments, or they focus too narrowly (or even exclusively) on their on-premises infrastructure, says cybersecurity veteran J. Wolfgang Goerlich, who serves as VP of strategic programs at CBI.
Now that companies and their end users can use hundreds of cloud-based apps, and multiple departments can spin up their own virtual server on an Infrastructure-as-a-Service platform, complete visibility across private cloud, public cloud, and traditional infrastructure is a must. A lack of visibility, says Goerlich, snowballs into much greater security risks than are necessary.
2. Every asset needs an owner.
If you lack 360-degree visibility, you probably lack ownership. Every piece of your hybrid cloud architecture needs an owner.
“A key tenet in IT security is having an owner identified for every asset, and having the owner responsible for least privilege and segregation of duties over the asset,” Goerlich says. “Lack of visibility results in a lack of ownership. This means, quite often, hybrid cloud environments have loosely defined access controls and often are without segregation of duties. Excessive permissions introduce risk, and unowned risk is unaddressed risk.”
