Compliance Operator scan rule ocp4-cis-node-master-file-permissions-etcd-data-dir seems to be aiming for the wrong path /var/lib/etcd when other similar rules about group and user ownership point to /var/lib/etcd/member.
Even the Description text says:

  Verify Permissions on the Etcd Database Directory
  To properly set the permissions of /var/lib/etcd , run the command:

  $ sudo chmod 0700 /var/lib/etcd

But the check seems to be based on /var/lib/etcd/member and the summary points to it too:

Result of item-state comparison	  Path	                    Type	   UID	GID	Size (B)	Permissions
not evaluated	                  /var/lib/etcd/member/	   directory	0	0	29	        rwxr-xr-x 

Tested on 4.18.10

Run Compliance Operator scan with rule ocp4-cis-node-master-file-permissions-etcd-data-dir

Run Compliance Operator scan with rule ocp4-cis-node-master-file-permissions-etcd-data-dir

Points to /var/lib/etcd    

Should point to /var/lib/etcd/member
