Kubernetes Security with Identity & OIDC

I interview Mark Boorshtein, the CTO of Tremolo Security, an open-source identity management company that focuses on authentication, authorization, identity, and automation. Mark explains that their most popular tool is Open Unison, which allows users to log in to their Kubernetes clusters with whatever authentication system they have, such as LDAP, AD, Okta, or Azure AD. Open Unison also provides secure access to the dashboard and integrates with other cluster management applications.
Next up we shift over to the issue of certificate revocation in Kubernetes. Mark explains that Kubernetes doesn't know how to handle certificate revocation, which can be a security risk if a certificate is leaked or an employee leaves the company. He recommends using OpenID Connect or impersonation to access the cluster instead of relying on certificates. Mark also discusses the default time to live on service account tokens issued by the Kubernetes cluster and the importance of not using service account tokens when talking to clusters
This episode provides insights into the challenges of identity management with Kubernetes and strives to help you improve the security of your Kubernetes clusters.
