What Hacker News says
4 sourcesFor an airgap lab, refer to the principal of Faraday Cage as a guideline.
For tighter control of reduced attack surface:
- libmusl instead of glibc
- pre-2013 CPU
- no UEFI
- no Management Engine (ME)
- replace BIOS with an open-source variety
- disable Write-Execute (relegate JIT to emulated VM; that’s web browsers too)
For an IT cybersecurity coordinator to have an hypothetical secured homeLAN system, he/she would need to set up:
- a RADIUS server
- a LDAP server
- an encrypted MAC layer via PKI
- a default-deny firewall (absolutely no VPN/DNSm/DoH/DoT pinholes)
- a transparent HTTPS proxy server with various ICAP servers scrubbing bad things
- a waterfall router (randomized packet jitters)
- a bastion DNS resolver
- internal authoritative DNSSEC servers (including cloned Root servers)
- personalized works
Read the rest
tations run on QubeOS
- test workstations on pre-prepared hardened OS
- VM servers run in strict software-emulated mode.
- disable JavaScript on all hosts’ OSes (guest VM and guestnet could have ‘em)
- VMs can only run Whonix Linux OS
- an intensive alerting system via heavily-sanitized SMS and email (but no public-facing, like Twitter)
and that is not counting any external servers needed to support the initial homeNET setup. You want VPN or exit-only Tor node, buy a cheap WireGuard’d VPS.
of course, then there is so many more security enhancements for Linux, on top of SELinux, Toyo, GRSecurity mostly in form of Linux kernel configuration tweaking.
Isn’t job security awesome?
