In this digital age, organizations are increasingly adopting cloud-native technologies such as Kubernetes to manage their infrastructure and applications. With this shift comes new challenges, particularly when securing sensitive data and protecting critical infrastructure against cyber threats.

In a Venture Beat article  discussing the benefits of viewing Kubernetes’ implementation within a Zero Trust perspective, Kubernetes’ vulnerabilities were found in its “relative newness and dynamic operating paradigm”, making the solution a target for cyberattackers.

A Zero Trust approach is essential to implementing Kubernetes securely, but there’s a few fundamental steps along the way.

First, security teams need to be asking questions and making decisions about what their policy rules are going to be for communications between their computing nodes. If the essential minimum types of connections and communications have not been identified, there is no way to know how to design a system securely.

‘Secure everything’ is a great idea—but can your team figure out all the details to actually do it? In practice, enterprise-scale services are so complex that they often cannot be fully secured in the way that Zero Trust demands. Some components (like Kubernetes clusters and nodes) are modern and more easily addressed, but security teams may not be capable of fully securing legacy applications.

Once a team has answered questions surrounding communication concerns, the next step towards implementing a version of Zero Trust is giving secure and trustworthy identities to all the nodes and applications in a system.

If you know the identities, you can apply a security policy to let them connect or enforce an exclusion as necessary.

Identities require digital certificates, and that’s where SecureG comes in.

Unlike traditional PKI, which was developed for web servers and employee credentials, SecureG’s solutions are designed for machine speed and machine scale—especially when there’s no human in the loop.

Our technology can help you build a strong PKI backed by the strongest possible root of trust for critical infrastructure. Contact us today to learn more.
