Rancher RKE2 must protect authenticity of communications sessions with the use of FIPS-validated 140-2 or 140-3 security requirements for cryptographic modules.
Use strong TLS settings. RKE2 uses FIPS validated BoringCrypto modules. RKE2 Server can prohibit the use of SSL and unauthorized versions of TLS protocols to properly secure communication. There i...Rule High Severity -

RKE2 must use a centralized user management solution to support account management functions.
The Kubernetes Controller Manager is a background process that embeds core control loops regulating cluster system state through the API Server. Every process executed in a pod has an associated se...Rule Medium Severity -

The Kubernetes Controller Manager must have secure binding.
Limiting the number of attack vectors and implementing authentication and encryption on the endpoints available to external sources is paramount when securing the overall Kubernetes cluster. The Co...Rule Medium Severity -

The Kubernetes API server must have the insecure port flag disabled.
By default, the API server will listen on two ports. One port is the secure port and the other port is called the "localhost port". This port is also called the "insecure port", port 8080. Any requ...Rule High Severity -

The Kubernetes API server must have the insecure bind address not set.
By default, the API server will listen on two ports and addresses. One address is the secure address and the other address is called the "insecure bind" address and is set by default to localhost. ...Rule High Severity -

The Kubernetes kubelet must enable explicit authorization.
Kubelet is the primary agent on each node. The API server communicates with each kubelet to perform tasks such as starting/stopping pods. By default, kubelets allow all authenticated requests, even...Rule High Severity -

The Kubernetes API server must have anonymous authentication disabled.
The Kubernetes API Server controls Kubernetes via an API interface. A user who has access to the API essentially has root access to the entire Kubernetes cluster. To control access, users must be a...Rule High Severity -

All audit records must identify any containers associated with the event within Rancher RKE2.
Ensure that the --audit-log-maxage argument is set to 30 or as appropriate. Retaining logs for at least 30 days ensures that you can go back in time and investigate or correlate any events. Set yo...Rule Medium Severity -
