Those topics seems a little advanced for a Linux user without cyber security knowledge though. I personally don’t understand any of them lol. I know what hardening is, what CVEs are; but except for few anecdotes like the logj4, xz, etc, I don’t think I’d know enough to talk about the cyber security side of linux.
I was thinking more along the side of daily life things. Like how programmer like linux because it’s easier to develop things and manage environments and cross program compatibility.
