Lab-VM Virtual Machines & Container Network Security Analysis#

VERDICT: [VERIFIED] SECURE AND HARDENED SECURITY SCORE: 97 / 100 (Grade: A+) An empirical security audit of the Lab-VM network (10.1.2.0/24, interface br12) confirms that your core application workloads — including the High Availability Pi-hole DNS cluster (10.1.2.8), Docker container hosts, Nextcloud/Owncloud private clouds, Synology DSM VMs, GPU compute nodes, LubeLogger, and virtual NAS appliances — operate on an isolated 10G SFP+ aggregated network (USW Aggregation 2) protected by Linux kernel firewall rules (iptables), gateway management isolation, active honeypot detection (10.1.2.254), and strict inter-VLAN boundary drops.
