Technically, if you safeguard root login following the best practices, this is not less safe than everyday ssh.

Even if it's very unlikely to utilize the flaw.

Leaving the option to login as root adds a security flaw.

Add firewall rules and sshd-rules like LoginGraceTime and MaxAuthTries to limit BruteForce attacks.

Independent from opening root login or not: Using ssh keyfiles is the only safe way.

Both of these ways wouldn't make me feel comfortable. Either login directly via ssh as root, or login via ssh and type sudo su or su - (.) as first command. So i strongly recommend: use sudo instead of the root userįrom the technical point of view: There are two common ways to use the root user. Having to type sudo before every command, that could change you system's behavior, at least adds one barrier which animates you to overthink your command. I have one user for monitoring, which has very limited access to logfiles and to the monitoring API.īut for me, personally, the most important point is that we all are humans. It has access to the files-to-backup and seperate ssh access to an off-site server. To add to the last point: I personally use seperate users for every task on my servers (I am the only admin): e.g. So one has to know two different passwords in order to become root) (I always use Defaults targetpw - as well on my desktop machine as on my servers.

Even if your default ssh login is compromised: An extra layer like sudo does make root permissions less accessible.

You have very granular options to adjust per-user permissions, is it through /etc/ssh/sshd_config or through the SUDOers file.

Commands using sudo are logged, this doesn't only apply safety when there are multiple admins, but also if some attacker got into your system.

If your ssh key for root-login is compromised, you have little chance to escape the situation properly.

I want to recap the ones I think are most important.why to use sudo

The other users already mentioned very good points. In addition, most remote administration frameworks, NAS systems, hypervisors, encourage usage of a root user for web login. But from how I see it, if a sudoers' user gets compromised, it's the same as compromising the root user, so game over. bots would normally try to probe for "root" user. The only benefit I can think of is security through obscurity i.e.

So is there any security benefits in creating a "proxy" user that you're going to sudo to root anyways, instead of directly providing ssh access to root? My thought is, if this is a desktop station, it makes sense and is recommended to use a non-root user for daily stuff, but on a server, you usually login to maintain it and 99% of the times all your activities require root permissions. For multiple people working on the machine, it's obvious that there is the audit trail benefit of having unique users for each actual person and fine-grained permissions. To clarify, we're talking about servers owned by a single admin. Where package_location is the path to the package.I'm trying to understand the technical arguments/security implications between ssh'ing with root directly, or making an auxiliary sudo user in the context of maintaining a server.
