8 Tips for Monitoring Cloud Security

Cloud security experts weigh in with the practices and tools they prefer to monitor and measure security metrics in the cloud.

Visibility Is Key

When it comes to security monitoring, most companies solely rely on what they get from their cloud providers, an approach Ford says may leave gaps in visibility particularly into workloads.

"You should have the ability to observe behaviors in every layer of your cloud infrastructure," he explains. This includes host visibility, container visibility, visibility into the control plane, and visibility into the application layer to see cross-site scripting, SQL injection, and other threats.

Cloud customers are getting smarter about limiting access to key services where important data is held, but attackers are also evolving. Instead of going directly for the data, intruders may instead look for keys they can use to access the service layer and establish persistence on the network. There, they can do reconnaissance and move laterally throughout the infrastructure, where they can find someone who has the IAM credentials they need to access data stores.

Most companies find it hard to maintain good security posture because they lack basic visibility into their hybrid cloud environments, CloudKnox's Parimi says. Many tools weren't developed to support dynamic cloud environments. For example, businesses trying to apply the principle of least privilege in the hybrid cloud use solutions that rely on role-based access control (RBAC).

"The problem with this practice is that traditional RBAC only works in a static environment," Parimi says. "This means that a typical privileged identity today has authority to perform many high-risk actions on a wide swath of critical infrastructure despite the fact that they only use and need a fraction of those privileges to perform their day-to-day jobs." This drives risk.

Oopsy: IaaS is "Infrastructure as a Service"
There is a reference in this article (page 3) on IaaS as "Internet as a Service". It is really "Infastructure as a Service".
