An introduction to Ubuntu Linux security



Linux is a very secure system, but it still pays to be cautious.

Security is one reason many users switch to Linux from Windows. With the rising importance of computers in daily life, more and more private data are stored on desktop systems. The hunt for bank account access keys has become big business, and many users also store private messages, business plans, and other sensitive information on home PCs. A fresh installation of Ubuntu is much less vulnerable than a comparable Windows system. Spyware, trojans, viruses, and other attack vectors have not settled in the world of Linux as they have with other systems, but it is important to understand some basic security if you want to keep your Linux system safe.
