Raspberry Pi for Home Labs and Security Projects

A Raspberry Pi is one of the cheapest ways to get an always-on, dedicated Linux box for lab work — running a target service, hosting a VPN endpoint, or (on authorized physical engagements) acting as a low-profile drop box.

When to use it

• An always-on target or service in your home lab, so you're not tying up your main machine
• Running Pi-hole, a personal VPN endpoint, or other always-on lab infrastructure
• On an authorized physical penetration test, as a discreet dedicated device left on-site with sign-off from the client — this is standard practice on real physical/red-team engagements, never something to do without explicit authorization

What to look for

• At least 4GB RAM if you're running anything beyond the lightest services — 8GB if budget allows
• A decent power supply and case with proper cooling — undervoltage and thermal throttling are the two most common Pi headaches
• A reliable SD card (or better, boot from USB/SSD if the model supports it) — cheap SD cards are a common point of failure for anything left running long-term

CanaKit's Raspberry Pi starter kits are the ones we point people to — they bundle the case, power supply, and SD card together, which covers most of what the mistakes below are actually about.

Common mistakes

• Underpowering it, then blaming performance on the Pi itself when it's actually an undersized power supply
• Leaving default credentials on any service you stand up "temporarily," then forgetting about it for months
• Deploying one as a drop box on a client site without explicit written authorization and a clear retrieval plan — this is a real, testable part of a physical engagement's rules of engagement, not an afterthought
