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.
There is one called OpenScan that’s available for Android
