Hardening, monitoring, and locking down Linux systems from the kernel up to running services. Content here covers practical workflows for taking a default install to a defensible production state: firewall rules, VPN tunnels, access controls, audit logging, and intrusion detection. Expect hands-on accounts of securing bare-metal hosts and hypervisors, including where AI agents can automate verification while humans retain authority over irreversible changes.

From Clean Hypervisor to Corp-Grade Bare Metal in an Afternoon

We took a freshly provisioned bare-metal hypervisor and turned it into a hardened, monitored, VPN-connected production host in a single afternoon. An AI agent handled the tedious verification; a human held authority over every irreversible step.
