Ensure that the API Server only makes use of Strong Cryptographic Ciphers

MediumLevel 1Manual reviewopenshift

Description

Ensure that the API server is configured to only use strong cryptographic ciphers. The benchmark marks this recommendation Manual.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

Ciphers for the API servers, authentication operator, and ingress controller can be configured using the tlsSecurityProfile parameter. The ingress controller provides external access to the API server. There are four TLS security profile types: • Old • Intermediate • Modern • Custom Only the Old, Intermediate and Custom profiles are supported at this time. Custom provides the ability to specify individual TLS security profile parameters. Follow the steps in the documentation to configure the cipher suite for Ingress and the API server.

How it is fixed

Fix method: Guidance or infrastructure patch

Use the Intermediate or above TLS profile, which requires a minimum of TLS 1.2.
