| ||Ask HN: Tips on Sysadmin Job|
69 points by linusb on Nov 25, 2021 | hide | past | favorite | 63 comments
Recently I got a promotion at my job. I was working with another guy in a small company with an even smaller IT department. That guy was fired and I got the position to be the only sysadmin at the moment. I never had any experience working and managing the whole IT infrastructure, because the company has 4 campuses around the city. I'm kinda confused on how to manage everything, my background is with information security and it's going to be a big challenge for me because it's my first job.

1. Require not 1, but 2 people, for hire, right now. It will take a long time until it gets approved, HR does their thing, and you (or someone else) hire people to help you.
2. Document, as fast as you can, all of the assets in your environment. Don't waste time on looking for software. Plain text or spreadsheet will do for start.
3. Identify the most important assets (servers, network devices, etc) - and try to understand what are your priorities for each. For example, availability for your frontend servers. Confidentiality and integrity for your server storing PII. Based on this, you'll understand what are your biggest risks. Would it be a business disaster if your website is down for few hours? Likely not. What about if the PII is compromised and you get huge fines and be in the news? More likely.
4. Find out who has the access to the most important assets, and cut off anyone who doesn't really need it.
5. Establish some sort of monitoring for the most important assets.
