🔍 Understanding Raspberry Pi Internet Connectivity: A Secure Networking Primer

Video: How to secure your Raspberry Pi ?

Raspberry Pi boards donā€™t ship with a magic ā€œsecure meā€ sticker. Out of the box they:

  • broadcast on port 22 with a globally known username
  • happily join any open Wi-Fi you point them at
  • trust every USB serial gadget you plug in

Thatā€™s why we, the battle-scarred crew at Why Piā„¢, treat every fresh board like a feral kittenā€”cute, but it will scratch your network if you donā€™t train it.

A 90-second history lesson (because context matters)

2012: first Pi ships, no on-board Wi-Fi, security an after-thought.
2016: Pi 3 adds 2.4 GHz Wi-Fi; suddenly everyoneā€™s dropping Piā€™s straight onto home routers.
2020: Pi 4 gets gigabit Ethernet + 5 GHz Wi-Fiā€”attack surface doubles.
Today: Pi OS still ships with the ā€œpiā€ user enabled. Sigh.

What ā€œsecurelyā€ actually means

Threat vector Real-world example Our counter-measure
Default creds Mirai botnet scans 22/tcp Rename user, key-only SSH
Plain-text traffic Someone sniffs your MQTT password WireGuard tunnel
Stolen SD card Room-mate ā€œborrowsā€ your Pi Full-disk LUKS encryption
Rogue Wi-Fi CafĆ© hotspot called ā€œFree_WiFi5ā€ Disable onboard radio, use Ethernet
