Policies regarding access to your ssh port?

Hi

What are your concerns/policies regarding access to your ssh port?
Do you use only ssh keys? Do you use a jump server? Do you use a private vpn like wirguard/tailscale/zeroteir/etc?

Thanks

  • Jump Server (whitelisted) + non-standard SSH port + keys only

    Thank you:)

    I normally use ssh keys and allow ssh connections on non-standard ports from everywhere.

    I've been testing tailscale and zerotier over the past few days, and they seem interesting, but when I reboot a server, the IP address becomes unreachable at random.

    I didn't have time to dig deep into this issue and it could be faulty setup from my side!

  • Well it depends on the environment and situation but that's how I do it.

    Different people have different ways of doing things.

    That's perfect! I have a Jump Server for convenience too.

  • I usually just use OpenVPN, but have ssh open as well (checking the connecting IP against a few DNS RBLs).

  • Random port + ssh key login + disable root login

    All of the above. I have a Nebula between all my servers as well as my desktop and laptop so we can communicate with each other using keys. I have two hosts with password login + TOTP which act as jumphosts for when I'm not at my laptop/desktop ( or, uh, if I don't notice a key expiring in the nebula ).

  • I normally just use SSH key, I do have a secondary method password with TOTP if am on a device that doesn't have the SSH key.

  • I normally lock the SSH ports to a couple of IPs and then SSH Keys everything. I do have a jump box too.

    Can't be bothered with changing the port, so just block it instead :joy:

  • With ssh port changed, I leave port 22 alive, to let CSF block the scanning bastards!

    lowendinfo.com had no interest.

  • keys only, standard port, no vpn, no jump box, no ip locking, fail2ban blocks persistent scanners. Maybe I should upgrade some of this but it hasn't been an issue afaict so far. For work boxes we are much more serious, but there are real admins running them too. Jump box istm works best if all your stuff is at a single provider like AWS, so you're less likely to have an outage at the jump host block all your stuff. Yes there are ways around that but it gets complicated.

  • Non-standard port, keys only, no root, raymii's cipherlist.eu, whitelist to two jumphosts on different providers. No whitelist when sshing via wireguard.

  • Keeping a server completely offline is one way to secure a server.

  • Changed port + only ssh key auth method + AllowUsers for me.

    I feel like this is a really personal question here. I mean who I let in my port is my business..

    I use different SSH port + port knocking + blacklisting everything that scans 22 + SSH keys on "root".

  • Never heard about a jump server BUT wouldn't that be putting all eggs in one basket? What happens if you forget to pay for your jump server or the IP gets changed?

  • Mentally strong people leaves SSH on port 22 where it belongs.
    There's no firewall restriction.
    Public key authentication required.

  • Wrote a script which (cron) reads 'special' dns names and opens ports to them. Key access only and non standard port.
    If I move around or an ip changes I update the dns and servers unblock.
    Works really well.

  • Port 22, IPv6 only with public key auth

    not recommended?

  • non-standard yet privileged port to slim down the logs, then (as a general rule):
    LogLevel VERBOSE
    PermitRootLogin no
    PasswordAuthentication no
    KbdInteractiveAuthentication no
    TCPKeepAlive no
    Compression no
    a single IP may or may not be allowed in the firewall (personal VPN rather than jump hosts) but usually it's more convenient to allow every IPs (occasional scp or rsync between different boxes)
