My Top 10 Tips for Securing Linux @home

In my previous post I shared how I learned that IT security is like physical security: we have to know our context, understand the threats in it and secure accordingly. Each person’s security needs are different. No-one can give a complete one-size-fits-all guide to securing everybody’s Linux environments at home.

However some general concepts apply. Here are the 10 things I look for when securing my own home Linux installations.

Major edit alert!

I’ve realised there is a lot more material here than would fit into the original two posts I had. So I’ve given each tip a post of its own.

And the tips are…

  1. Enable and use an OS-level firewall
  2. Enable SELinux or another Mandatory Access Control mechanism
  3. Use sudo
  4. Apply software updates automatically or often
  5. Use encryption
  6. Use multi-factor authentication
  7. Enable threat-detection
  8. Browse securely
  9. Limit running services
  10. Backup securely

That’s it! More on each of my top 10 tips shortly. Meanwhile, what do you think of these tips? Please let me know in the comments below.

A glossary of terms is available here.

Once again, ensure you’re familiar with the disclaimer here!
