What is best practice when it comes to security updates on linux servers?
How should it be handled?
A lot of desktop systems are applying updates automatically but they are not mission critical either.
I use
yum-cronon RHEL 7/CentOS 7
I usednf-automaticon FedoraI only have a couple of Debian based servers and I keep being lazy about setting something there.
This is the package for it on Debian
https://wiki.debian.org/UnattendedUpgradesSo do you both download and apply them automatically?
Security updates only or everything? -

https://wiki.debian.org/UnattendedUpgradesWhat @JaredBusch said. My first thing to setup/configure when making a new base image is the automatic update, dnf-automatic, yum-cron, or Unattended-Upgrades as the case may be.
Since I just did a new Debain and Ubuntu base this past weekend, for those it's
apt install -y unattended-upgrades && systemctl enable --now unattended-upgradesThose all handle security updates, which should always be up to date.

Security updates only or everything?Download and apply, everything
But this is a low risk IMO as each VM is a single task.
Not like updating very package ever on a server.

The more mission critical, the more you want automated updates!
If you are big enough to have patch testing, then that's great and you should do that (if it makes financial sense.) But you have to be really, really big before it's financially viable as you basically need a full time staff, loads of compute resources, and a team that's doing that constantly and makes decisions lightning quick.

Security updates only or everything?Security absolutely for sure. But often, everything. I always do security automatically. The other/rest is more situation by situation, but it's rare that I want (or a customer wants) to pay for updates when they could be automatic and faster.

Literally was doing this today for a F100 customer

Naming customers in public is not something people do in IT. Nor is in considered okay to ask.
-
This whole approach of not doing updates on mission critical system is nonsensical. Admins need to grow a set and setup automatic updates on everything by default. If stuff breaks when you update it, that's on software vendor, period.

I can't remember where you fall on the asking about salary thing?

LOL - sure of course, we'd love this to be true... it may be on the software vendor, but it's still on you as the one who has to support it for the company.

@Dashrender I believe @scottalanmiller said that it is okay to share what salary you earn.

Salary is a personal matter. You should always be allowed to disclose details about yourself.

Only if you chose it, and if you chose a vendor that doesn't have working software, that's something to ponder.

Exactly, I've actually seen that before. But it's well known in the industry, too. In high end positions, people discuss their salaries all of the time.
It's not just within a single company. The entire IT industry does this. IT pros are constantly hiding their salaries, or worse, claiming that those that make better salaries than them are lying or anomalies. You see it here on ML a lot. People feel badly that they've negotiated so low and resent people finding out, but people with decent salaries often share, and get attacked for showing what can be earned.
There's so much pressure to shame people into hiding their salaries and IT pros tend to be very susceptible to that kind of pressure that we have an industry earning so much less than it should.

What industries don't you find this in?

Well my exposure is less. But what I've seen everything from medical to manufacturing to finance to business to retail people share wages much more freely.

I've always assumed that keeping salary private was the norm as I've never really seen or heard anyone discuss it before. I'm sure it happens from time to time, but I think people want their income kept private.
