We use templates for network devices, workstations, laptops, and servers so that all of our devices match our security templates. Network Device Configurations. For network devices, we should consider using RADIUS/TACACS+ for authentication purposes, not a shared user account. How do we do this kind of monitoring?

While at DockerCon 2016 in Seattle today, I took some time on the expo floor to talk to a number of different vendors, mostly focused on networking solutions. Using eBPF, Plumgrid has created in-kernel virtual network functions (VNFs) that do things like bridging, routing, network address translation (NAT), and firewalling.
