Common the web servers like Nginx, Caddy are not secure? If they found a zero day in these application whole Internet will go up in flames.
20 years ago, when I was still young and naive, I took these concerns way too serious, remapped ports, believed in pwn, set up fail2ban and knocking, rotated logs. Later I realized it was all just FUD, even back then. You run on 22, 80 and 443 like a chad, use pw-based auth if you’re lazy, ignore login attempts and logs in general and never visit a server until it needs reconfiguration. Just say f* it. And nothing happens. They just work for years, the only difference is you not having tremors about it.
The only time a couple of my vpses were pwned in decades was a week after I gave a sudoer ssh key to some “specialist” that my company decided to offload some maintenance to.
What changed from back then is that software became easier to set up and config and less likely to do something stupid. Even your dog can run a vps with a bunch of services now.
Good luck. Some people have different experiences.
With opensource and how code works in general, we are all in the same boat with bigcorps and megacorps. And they receive the same updates at the same rate (maybe minutes faster cause they host repos).
This quote, "you can't be certain the software you use is secure", is technically true but is similar to the "you can't be certain you won't die buying groceries". Perfectly useless fearoid for your daily life.
But the way you phrase it isn't really convincing, and for singling out 443 and 80 ports. As the subthread of breaches hint towards. You might not need to be worried about nginx, but whatever you host on nginx might be a problem and being "certain the software you use is secure" is also pretty darn useless as guidance.
* Try to avoid it in the first place.
* Do research, minimize risk and make whatever compromises you are willing/able to make
* Isolate it
* Maintain, update and monitor it
Be aware of your threat model and the risks associated.
better off using key only logins and forgetting IMO
This happens _all_ _the_ _time_
Don't move the goalposts. I'm certainly not saying that nginx is insecure. I'm saying that if you think any piece of software written after the 80s has reached the point where it won't have 0 days anymore you just haven't been paying attention
