A simple question to this community, what are you self-hosting? It’s probably fun to hear from each-other what services we are running.

Please mention at least the service (e.g. e-mail) and the software (e.g. postfix). Extra bonus points for also mentioning the OS and/or hardware (e.g. Linux Distribution, raspberry pi, etc) you are running on.

    It was meant more as a joke than criticizing hosting your own services. I personally have a VPN with MFA, and services that I host for my self that are segmented to a paranoid level (home camera system on own vlan, restricted from being able to reach any other vlan or the Internet, etc) with a deny all and explicit allows on per host and traffic type. The amount of work that went into building the network is probably overkill, and it is still susceptible to nation state and supply chain compromise but hopefully whoever gets in will curse me if they try to move around the network.

    Realistically, every added service and host is added attack surface and chances for misconfiguration \ supply chain attack, but being alive is a risk too…

    I’m guessing system admins and dev op is over represented here so some of our home networks may be targeted as a path into a corporate environment, but I’m guessing the chances are low. Sadly even the most secure networks are not an impossible target. The attackers are well ahead of defenders of networks. Attackers need exceptions, while defenders need everything perfect. Much harder to accomplish.

        For best practice, my personal recommendation would be to not have any service public facing besides a VPN that requires MFA. segment self hosted services into separate VLANs based on how sensitive the content is. Disallow all traffic between VLANs unless required and only allow based on port number, specific resources needed. Don’t forgot to disable outgoing Internet access unless required. Devices like Chinese made video cameras should never have an Internet connection.

        My network looks something like: home vlan, work vlan, Netflix \ hulu streaming devices, cctv, wireless work, wireless home, wireless guest, iot, servers, network management. Would be way overkill for vast majority of people, but I would be hypocritical not to considering what I do and I do have a different threat profile than most.

        Another thought: self hosted through VPN with MFA and nothing public facing is probably safer than cloud as long as you have cold backups.
