Rancher MCM must use a centralized user management solution to support account management functions. For accounts using password authentication, the container platform must use FIPS-validated SHA-2 or later protocol to protect the integrity of the password authentication process.

Description
RBAC Integration and Authn/Authz Centralized authentication services provide additional functionality fulfilling security requirements: - Multi-factor authentication, which is compatible with Rancher MCM. - Disabling users after a period of time. - Storage and transmission of secure information is encrypted. - Secure authentication protocols such as LDAP over TLS, or LDAPS using FIPS 140-2 approved encryption modules. - PKI based authentication. Rancher MCM can integrate with external centralized authentication but does not offer a native solution. The authentication mechanism needs to be initially enabled and configured. The proxy authenticates users and forwards their requests to Kubernetes clusters using a service account.

ℹ️ Check
RBAC Integration and Authn/Authz View and modify authentication settings through the Rancher MCM UI. Navigate to Triple Bar Symbol(Global) >> Users & Authentication >> Auth Provider. This screen shows the authentication mechanism that is configured. If no authentication mechanism is configured or disabled, this is a finding.

✔️ Fix
RBAC Integration and Authn/Authz Navigate to Triple Bar Symbol(Global) >> Users & Authentication >> Auth Provider. From this screen the authentication mechanism can be selected and configured. This STIG is written and tested with KeyCloak and not included with Rancher MCM. Installation instructions for KeyCloak can be found here: https://www.keycloak.org/getting-started/getting-started-kube
