Assessment Title
Rule Text
Rancher RKE2 must protect authenticity of communications sessions with the use of FIPS-validated 140-2 or 140-3 security requirements for cryptographic modules.
Description
Discussion Text
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 is a lot of traffic between RKE2 nodes to deploy, update, and delete resources so it is important to set strong TLS settings on top of this default feature. It is also important to use approved cypher suites. This ensures the protection of the transmitted information, confidentiality, and integrity so that the attacker cannot read or alter this communication.
The use of unsupported protocol exposes vulnerabilities to the Kubernetes by rogue traffic interceptions, man-in-the-middle attacks, and impersonation of users or services from the container platform runtime, registry, and key store.
To enable the enforcement of minimum version of TLS and cipher suites to be used by the various components of RKE2, the settings "tls-min-version" and "tls-cipher-suites" must be set.
