I am often asked for advice on doing various things on a computer and I assume that they are doing everything else securely, and then I find that they don’t have the basics right. So here is my guide to doing the basics right.
Don’t use Windows
OK so some people still haven’t upgraded to a Linux distribution, and I have hit brick walls in trying to convince some of my friends to do this. But this is one of the best things you can do to improve your security. OK keep a separate partition with windows for playing games, everything else is better on Linux.
Update, Update, Update
Make sure that you keep all your software up-to-date, not just the operating system, all those other bits and pieces of software need updating.
When you install software always do this by adding a repository to your package manager, that way when you do your apt full-update everything is updated in one go. (this is one of the main reasons why Linux is better)
Backup, Backup, Backup
All computers can fail, taking your data with them, so you need to make sure the rule of 3 is followed. All data should have 3 copies, the live version, a backup version, and a remote backup.
Use a password Manager
We are just frail humans and we can not remember a different, complex password for every site we need or want a password on. The only way to remember all these passwords is to use a password manager. There are better and worse managers out there but you are much safer using a bad password manager than not using one at all.
