opencve VS vulnix

Don't like someone else running it? No problem, it's open source and you can run it yourself https://github.com/opencve/opencve

I use https://www.opencve.io you can make a account and then subscribe to different products and/or vendors to get automated updates via mail if there are new vulnerabilities that affect these products

www.opencve.io and filter on your vendors and hw models.

Check out OpenCVE, I find it as an excellent tool.

https://www.opencve.io/ - Site that allows you to be emailed of new CVEs by subscribing to different products and vendors.

https://www.opencve.io/ is something to use as well.

it is very easy to scan your entire dependency tree for known vulnerabilities for Nix, all the way up to a whole OS

Initially I spent a lot of time as I used it as an opportunity to learn Nix/NixOS. I used Nix intentionally as it's a rolling release and also it's declarative and intended for reproducible deployments, so I don't need to deal with an OS like Ubuntu that slowly gets crufty and out of date and needs a clean-up or upgrade or complete re-install. And if I do need to re-install, it should be mostly a one-liner.

For security there are these scanners:

I also run all services in docker and my network uses VLANs behind an OPNSense firewall. I use Wireguard as a pinch point into my network to access most services. So I'm not too worried about the security aspect.

Upgrading on Nix is pretty easy - just bump your lock file and it will get the latest packages, assuming you are on the unstable channel. But unstable does break on occasion. You an also use the latest stable release of Nix and selectively choose unstable packages, which is probably the way to go. I rarely need to fix anything - it's pretty stable. It only starts eating time when I want to add or upgrade some element to the system, but I always make sure to never do any action that isn't captured in Nix config and backed up, so that I don't have to come back and figure out what exactly I did or how something works again. It's been fine. Nix has a pretty steep learning curve, but considering its power, I think it's absolutely worth it.

Along with the results of the diff the comment also provides the results of running vulnix
