Despite an increase in the size of the basic Linux code in the past six months, it remains one of the most secure pieces of software available, according to a recent study by Coverity, a developer of source code analysis tools. The study found that the most recent release of the Linux kernel is free of major defects, compared with the discovery of six critical defects at the end of December 2004. Even then, the open-source Linux was considered more secure than most commercially developed software.
