Why do pentesting in your homelab if the objective is not to learn? (self.selfhosted)

Hi, I was recently watching a few David Bombal videos, in which he talks about various pentesting methods (Eg: this and this).

My question is: if you're not looking to actively learn about pentesting, what other benefits would such efforts offer for your homelab? Setting up automatic pentesting routines to check if your network has been hacked? Just fun?

I'm not trying to be a pentesting expert but it seems really cool, it's just that since I will likely not be using it daily for my job/at home, I will quickly lose motivation to keep doing it. What do you use pentesting for in your homelab?

Thanks!

That is a good idea. Could you tell me more about how you automate pentesting your network?

[–] possiblylinux127 1 points 1 year ago (1 children)

I don't ready automate it but I usually start by running nmap scans to make sure there isn't any ports exposed that shouldn't be exposed. You'd be surprised how much more secure you systems will become once you lock it down.

Also check your SSL configs to make sure there aren't any config problems.

I also ran the automated scans that were built into nextcloud

You don't need to get super in the weeds, but depending on what your self hosting. Are you hosting just in your lan? Or are you opening ports to the internet. How sensitive is the information on your computers? If anything your hosting is avail to the internet, it's A very good idea to learn and be able to test your networking at least to confirm only ports you want to be open are open, or firewalls configed proper, between vms, containers,etc. Pen testing tools are great for automating those things and can be invaluable in identifying weaknesses. You don't need to keep up with it. Use the tools to identify where your self hosted service could use changing, and then make the changes. Run the tests when major updates or you change servers or upgrades.
