BasicSecurity:
The most basic set of rules
If you're a simple desktop user who only uses his computer for the most ordinary things, then this is the basic rule set:
1. immediately install security updates when you're notified;
sudo apt-get update && sudo apt-get upgrade
2. do not install antivirus, as you *really* don't need it in Linux;unless you share files with Windows
3. enable the firewall (sudo ufw enable) without further tweaks;
4. stick to the official repo's as much as possible, and only deviate from them
when strictly necessary and with much caution;
5. keep Java (both openJDK and Oracle Java) disabled by default in your
browser, and only enable it when needed;
6. use Wine with caution;
7. and most important of all: use your common sense. The biggest security threat is generally found between keyboard and chair.
