> SYS_QUERY: PROJECT_OVERVIEW
> Built a secure, isolated lab environment on a Proxmox host to safely test malware payloads and analyze network traffic without risking the main host infrastructure.
> SYS_QUERY: EXECUTION_LOG
> Provisioned 4 Debian containers via code. Segmented the virtual LAN, configured strict firewall rules, and routed all outbound traffic through a dedicated VPN tunnel.
> SYS_QUERY: MOTIVATION
> Required a sandbox environment to understand exactly how common network scanning utilities interact with different subnet mask configurations.
> SYS_QUERY: ACQUIRED_INTEL
> Mastered complex sub-netting and discovered that overly restrictive default-deny firewall policies often break internal DNS resolution if not carefully managed.
> SYS_QUERY: FUTURE_ITERATION
> Next phase: fully automate the entire container deployment and network stack using Ansible, reducing reconstruction time drastically.
