I guess I’m extremely paranoid then, my home IP doesn’t change much and I just expose the port only to it from Oracle’s site. I rarely touch mine though.
Comment on How safe is self-hosting a public website behind Cloudflare?
7Sea_Sailor@lemmy.dbzer0.com 6 months agoChange the ssh port to something with 4-5 digits, disable ssh password Auth and use certificates only, don’t expose any port other than 443.
If you’re paranoid, use cloudflare as a proxy and set the VPS firewall to only accept incoming traffic from cloudflares ip list.
That’s about it really.

The Oracle Cloud VPS only has SSH key authentication enabled by default. You can also set it to only allow SSH from your home IP in the virtual firewall before the machine is ever spun up.
Their current free ARM offering is 1 machine with 4-cores and 24gb RAM for life. You can also add another 2 AMD machines with 1-core and 1gb RAM and still be in their free-tier.
If you’re going to set it up and take advantage of the ARM machine, make sure you pick a home location for your account that has multiple availability zones. San Fran right now only has 1 zone, so if the shared ARM instances are all used up, you’ll have to wait a few days and try again. Phoenix I think has 3, so you can try with another zone right away.

Changing port is security by obscurity and it doesn’t take much time for botnets to scan all of IPV4 space on all ports. See for example the ever updated list that’s available on Shodan.
Disable password login and use certificates as you’ve suggested already, add fail2ban to block random drive-bys, and you’re off to the races.
