You’ve heard that Linux is a very secure operating system. You’ve heard it’s practically immune to viruses (practically being the key word). You’ve heard it’s tough to crack. These are all true…and with good reason. Linux is such a strong operating system for two primary reasons – by design and with the help of security systems like AppArmor and SELinux.
