Building The Raspberry Pi: Securing the Raspberry Pi

This post is part of the series on building my new Raspberry Pi; this series is a sub-series of the Adventures with a Raspberry Pi.

The official Raspberry Pi site has details on how to secure the Raspberry Pi. The page covers the following:

1. Change your default password
2. Change your username
3. Make sudo require a password
4. Ensure you have the latest security fixes
5. Improve SSH security
6. Use key-based authentication
7. Install a firewall
8. Installing fail2ban

I’d recommend taking a read through the page and enacting at least some of the above.
