From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Is it just as secure doing this (with crowdsec) vs hosting on a rented server from a cloud provider?
My site is on a rented server at digital ocean. Some providers do more or less to protect you themselves though. I don't think digital ocean does much monitoring or protecting, I've had servers on there compromised in the past that would have been caught by my current setup. It can't hurt in any case.
I also run crowdsec on my home setup but I don't have any open ports at home and never get alerts. I had suricata running and plugged into crowdsec as well so it would handle blocking for both, but suricata never got to get any action with crowdsec blocking malicious activity, so I disabled it to save resources.
I don't mean about relying on the protection from these providers. I am talking about the inherent increased security of hosting on a server that's on a different network than your local network.
Oh gotcha. It was late when I replied :p. You absolutely get security with a layer of separation from hosting remotely. I monitor my home network and have a similar setup but I don't host anything from here. I never get attacked or probed at all compared to my remote server. Just having those open ports makes you a target. Once a few scanners pick up on you hosting content you will absolutely start getting attacked. Another benefit is you don't have to have any passwords on your remote host, just an ssh key. They can bruteforce all they want, good luck without a zero day. You also keep your personal IP address out of peoples scope by not hosting from the local network.
I used to run much heavier protection on my home network, but after keeping an eye on all the logs and alerts for a while I realized I was just wasting ram and storage space mostly. Sane firewall settings is enough for a typical home, and something like crowdsec is probably overkill.
Now if you are hosting stuff it's a different story. I would actually harden my local network MORE than I did the remote one due to much more of my personal stuff being on my local network. My remote host being compromised would be a mild hassle at most, It does self backups once a week, and I have my entire site in a private git repo I sync to. It would take a few minutes to throw up another server, if my home stuff got compromised a lot more damage could be done.
