CKS course: CIS-benchmark reference to "Distribution Independent Linux" doesn't exists

Kubernetes
#1

Hi, I’m going though CKS kodekloud course. Course has reference links to CIS-benchmarks to check “Distribution Independent Linux”. But I don’t find such a section in CIS-benchmark. Can someone guide me to the right url? Below is the text from the course.

Go to the Operating Systems section and search for the Distribution Independent Linux. Expand it to see more options, then download CIS Benchmark.

Please include a link to the lab in question, so I can take a look. Thanks!
