Basically every local service is accessed via a web interface, and every interface wants a username and password. Assuming none of these services are exposed to the internet, how much effort do you put into security here?
Personally, I didn’t really think about it when I started. I make a half-assed effort at security where I don’t use “admin” or anything obvious as the username, and I use a decent-but-not-industrial password - but I started reusing the u/p as the number of services I’m running grew. I have my browsers remember the u/ps.
Should one go farther than this? And if so, what’s the threat model? Is there an easier way?
IPv6 should not be disabled under any circumstances.
In fact, many devices in my house have IPv4 disabled. Disabling IPv4 on my public-facing SSH reduced the attack traffic to zero.
IPv4 is shit.
IPv6 was just found to have a critical exploit, and the solution is to disable it.
The only windows machine on my home network is the backup Windows laptop that I only boot when I need to run something like Odin to flash a tablet or some niche Nintendo switch management software.
And now your entire system/network is vulnerable because of it. Great idea!
Yes, the machine that stays off 363 days of the year is such a security risk to my home network 🙄
Great, so let’s suppress a warning because YOU are fine…
Maybe other people don’t realize the issue, but of course you aren’t thinking about anyone but yourself now aren’t you?
I’m pretty sure that vulnerability only affected windows machines. Surely you’re not running a homelab with windows server?
Wouldn’t any windows device in your network be vulnerable? And from there everything else.
Lol, right, right. It’s only run the internet for what, 40 years now?
Guess you missed the recent gaping hole in IP6 on Windows?
IP6 is only really useful in large (i.e. enterprise) environments . It offers no practical benefit to small networks at the moment.
And even enterprise will only switch as they build out new infrastructure. The cost to switch is very high, and the risk is far more concerning than any potential benefit.
How many people are running public facing windows servers in their homelab/self-hosted environment?
And just because “it’s worked so far” isn’t a great reason to ignore new technology.
IPv6 is useful for public facing services. You don’t need a single proxy that covers all your http/s services.
It’s also significantly better for P2P applications, as you no longer need to rely on NAT traversal bodges or insecure uPTP type protocols.
If you are unlucky enough to be on IPv4 CGNAT but have IPv6 available, then you are no longer sharing reputation with everyone else on the same public IPv4 address. Also, IPv6 means you can get public access instead of having to rely on some RPoVPN solution.
Any device on the network would make it vulnerable, what does a server have to do with anything?
If the router/gateway/network (IE not local) firewall is blocking forwarding unknown IPv6, then it’s a compromised server connected to via IPv6 that has the ability to leverage the exploit (IE your windows client connecting to a compromised server that is actively exploiting this IPv6 CVE).
It’s not like having IPv6 enabled on a windows machine automatically makes it instantly exploitable by anyone out there.
Routers/firewalls will only forward IPv6 for established connections, so your windows machine has to connect out.
Unless you are specifically forwarding to a windows machine, at which point you are intending that windows machine to be a server.
Essentially the same as some exploit in some service you are exposing via NAT port forwarding.
Maybe a few more avenues of exploit.
Like I said. Why would a self-hoster or homelabber use windows for a public facing service?!
… all it can take is going to a website from a windows device… maybe less, it was literally discovered a couple days ago…
Yes it actually kinda does, that’s why this exploit is considered the highest priority and critical.
But sure… downplay it, because we only think servers are at risk…
Yeesh buddy.
The internet is not a “small network”, and I assume your small network is connected to it. You need local IPv6 routing to have access to IPv6-only hosts which are becoming more and more because it’s reasonable in terms of price to get an IPv6 block unlike IPv4 blocks which are being auctioned for tens of thousands of dollars at this point (!!!).
Also restoring global addressing is a huge benefit. P2P communications in IPv4 has become an insane mess of workarounds due to lack of addresses and this becomes worse the more layers of NAT you stick behind each other to try to save your ass from the rising tide.
I’m really sick of hearing these idiotic excuses over and over, “it’s hard” this, “it’s unsafe” that, “it’s expensive”, “understanding the eldritch secrets of IPv6 has driven 5 of my colleagues into madness” skill issue. THERE ARE NO MORE IPV4 ADDRESSES. So unless your network is so fucked that you haven’t managed to fix it in 26 years, since IPv6 has been standardized, or it really is just an internal network with no outward facing services where it doesn’t matter when someone who just has IPv6 can’t access it because they wouldn’t be able to access it anyway, and you’re not some kind of ISP, you have no reason not to have support for it at this point and you absolutely never have a reason to tell people it’s not “useful” because that is straight up wrong in the general case even if it might be true for your situation.
