I use Arch, btw. But I run the linux-hardened kernel, doing pacman -Syu once a week.
I also run endlessh on TCP port 22, and a fake HTTP server as a community service.

I see some posters saying it's not good practice to run Arch, but I think distro alone is not an answer to your security concerns.
I'm on CenturyLink fiber, they are apparently so incompetent they can't take my money for a static IP address, so whoever is doing HTTP requests is blindly trolling CenturyLink residential IPv4 blocks. Nobody doing this is up to anything legit.
