Setting up an open-source inventory management system — what security checks should I do?

During setup, never grant 'root' privileges to the database user; create a restricted user with access limited only to that specific app's database. Enable UFW on the server and block all unnecessary incoming ports except 80 and 443. And definitely don't skip configuring a free SSL certificate.

When pulling code from a repo, run these 4 checks: 1) Are the GitHub stars and contributor history organic? 2) Are there unresolved issues under the security advisories tab? 3) What license does it use, and are there commercial restrictions? 4) Are there hidden scripts pinging external servers?

We've been running an open-source ERP/inventory module for 3 years. We pay 320 TL a month for the VPS and 80 TL for encrypted off-site backup storage. Doesn't even hit 5.000 TL a year. But we did pay an outside consultant 15.000 TL upfront for installation and hardening, and it was 100% worth it.

What happens when your tech friend takes another job or the server crashes down the line? Open source software is free, but support and maintenance are not. If your system locks up in the middle of month-end invoicing, the downtime could cost you far more than that license fee.

Don't push the downloaded software straight to production. Seed it with a few fake inventory items from your old records and test it across your branches for at least two weeks. It gives your staff time to get used to it and lets you watch for unexpected error logs in the background.

definitely get static ips for the branches. honestly if you put a web panel open to the world automated bots brute forcing passwords will crash your server learned that the hard way.

So when an update drops for open-source projects like this, can you update with a single click like a mobile app, or do you have to reinstall the whole thing from scratch?

Make it a non-negotiable rule to take automated weekly server image snapshots and ship daily database dumps to a separate email or cloud bucket.

The answer above hits the nail on the head. Forgotten test environments are more often the entry point than live systems.

If you have questions, write them; I'll answer as best I can.

It's rare to find an explanation this clear.

I'm writing this so you don't make the same mistake. anyway mistakes made on the open-source inventory software side are usually reversible but expensive.

Great work.

you're right then taking nots for two weeks yields better results than a six-month estimate.

the harder it is to reverse a decision, the slower you shuld make it.

I agree.

I didn't know that.

Here's how it went for us. Don't rely on a single measure; go layer by layer.

When we decide without measuring, we always end up in the same place. If you have questions, write them; I'll answer as best I can.

I felt relieved reading this answer, so it's not just me. An untested backup is not a backup.

Of course it varies if your situation is different.

Thanks for posting. Everyone rushing into open-source inventory software gets stuck at the same point.

Hasty decisions become decisions you have to fix six months later. Just leaving this note, it might be useful.
