Anyone have any good external pen testing tools that you’ve used on your self hosted setup? Mine is pretty secure overall but I would like to be able to scan the WAN for vulnerabilities or misconfigurations just to make sure I haven’t missed anything.

Check out openvas.

I use Nessus professionally, they are somewhat similar. I can’t decide which one has the worse user interface.
Another +1 to openvas. Specifically, I have had much luck with this Dockerized version: https://github.com/immauss/openvas
Plus 1 to openvas. UI is indeed horrendous though.
Be careful running high load tests against sensitive devices. I once ran it against a PoE switch I used for my cameras and it did something so crazy that it required me not to only power cycle the switch, but to disconnect all the cameras first and then power cycle. Was super confusing and felt like it found a way to short the device lol. Scared the hell out of me.
That being said, I’ve found many many things to improve on my devices thanks to openvas.
I had a colleague at work years ago who did his Master’s thesis on network scanning. He ran a PoC in the company’s network and had all the printers print hundreds of pages.
We learned that printers suck and that we should always know our payloads and targets 😁

You can try to scan your server with vulnerability assessment tools such as Nessus (it is available as a docker container) or sn1per which is open source.
sn1per is not open source, according to the OSI’s definition
The license for sn1per can be found here: https://github.com/1N3/Sn1per/blob/master/LICENSE.md
It’s more a EULA than an actual license. It prohibits a lot of stuff, and is basically
source-available.You agree not to create any product or service from any par of the Code from this Project, paid or free
There is also:
Sn1perSecurity LLC reserves the right to change the licensing terms at any time, without advance notice. Sn1perSecurity LLC reserves the right to terminate your license at any time.
So yeah. I decided to test it out anyways… but what I see… is not promising.
FROM docker.io/blackarchlinux/blackarch:latest # Upgrade system RUN pacman -Syu --noconfirm # Install sn1per from official repository RUN pacman -Sy sn1per --noconfirm CMD ["sn1per"]The two
pacmancommands are redundant. You only need to runpacman -Syu sn1per --noconfirmonce. This also goes against docker best practice, as it creates two layers where only one would be necessary. In addition to that, best practice also includes deleting cache files, which isn’t done here. The final docker image is probably significantly larger than it needs to be.Their kali image has similar issues:
RUN set -x \ && apt -yqq update \ && apt -yqq full-upgrade \ && apt clean RUN apt install --yes metasploit-frameworkhttps://www.docker.com/blog/intro-guide-to-dockerfile-best-practices/
It’s still building right now. I might edit this post with more info if it’s worth it. I really just want a command-line vulnerability scanner, and sn1per seems to offer that with greenbone/openvas as a backend.
I could modify the dockerfiles with something better, but I don’t know if I’m legally allowed to do so outside of their repo, and I don’t feel comfortable contributing to a repo that’s not FOSS.
