When I first got into self hosting, I originally wanted to join the Fediverse by hosting my own instance. After realizing I am not that committed to that idea, I went into a simpler direction.
Originally I was using Cloudflare’s tunnel service. Watching the logs, I would get traffic from random corporations and places.
Being uncomfortable with Cloudflare after pivoting away from social media, I learned how to secure my device myself and started using an uncommon port with a reverse proxy. My logs now only ever show activity when I am connecting to my own site.
Which is what lead me to this question.
What do bots and scrapers look for when they come to a site? Do they mainly target known ports like 80 or 22 for insecurities? Do they ever scan other ports looking for other common services that may be insecure? Is it even worth their time scanning for open ports?
Seeing as I am tiny and obscure, I most likely won’t need to do much research into protecting myself from such threats but I am still curious about the threats that bots pose to other self-hosters or larger platforms.
Yeah, a few weeks ago a achieved my state of “secure” for my server. I just happened to notice a dramatic decrease in activity and that’s what prompted this question that’s been sitting in the back of my mind for weeks now.
I do think it’s important to talk about it though because there seems to be a lack of talk about security in general for self hosting. So many guides focus on getting services up and running as fast as possible but don’t give security much thought.
I just so happened to have gained an interest for the security aspect of self hosting over hosting actual services. My risks for self hosting is extremely low so I’ve reached a point of diminishing returns on security but the mind is still curious and wants to know more.
I might write up a guide/walkthrough of my setup in the future but that’s low priority. I have some other not self hosting related things I want to focus on first.
