ROCK Sensor Hardware Options
This document is a list of hardware that has been used for development and home use as a ROCK sensor. The first option would be to repurpose a machine if possible (minimum specs below). If your budget permits you can build a powerful system in a small form factor for under $1000.
Some of the more important aspects to look for are IPMI for baremetal remote management, dual Intel NICs, quiet, and relatively low-power. You don't want to have to wear hearing protection while sitting next to your infrastructure.
Sensor Hardware Options
- minimum specs: 2 nic / 4 cores / 8G RAM / SSD if possible
These are merely starting points as hardware capability and price points are a moving target.
~$900 Slim Xeon Build:
Intel NUC 8I7HVK - newest i7 with dual gigabit NICs
Shuttle Barebones Systems (dual NIC)
Traffic Monitoring Hardware Options
Some routers and firewalls have "port mirroring" options as well. Here's some budget options. I recommend getting at least a gigabit device if you can afford it. There are much cheaper options for 100M Ethernet.
- Dualcomm ETAP-2003 ~ $220
