Is there some sort of comprehensive guide on hardening RHEL clones like Alma and Rocky?

I have read Madaidan’s blog, and I plan to go through CIS policies, Alma and Rocky documentation and other general stuff like KSPP, musl, LibreSSL, hardened_malloc etc.

But I feel like this is not enough and I will likely face problems that I cannot solve. Instead of trying to reinvent the wheel by myself, I thought I’d ask if anyone has done this before so I can use their guide as a baseline. Maybe there’s a community guide on hardening either of these two? I’d contribute to its maintenance if there is one.

Thanks.
