OpenBSD v4.9 releases the world's safest operating system

OpenBSD is probably the safest operating system in the world. Every step on top of it http://www.aliyun.com/zixun/aggregation/17799.html "> The development process is focused on building a secure, open, and free platform. UNIX® and linux® Administrator Note: You may have used the tools you've ported from OpenBSD in your daily work, but you just don't know it. Perhaps we should now do a more in-depth study of the entire operating system.

When security is the most important consideration, it is necessary to study the operating system that generates the standard OpenSSH (Open secure Shell) for secure remote access. OpenSSH is only part of the OpenBSD, and the distribution is focused on security from the bottom up, and it implements the goal of creating a default-safe class UNIX® operating system. This position differs from most operating systems today and requires a lot of time and effort to strengthen the environment before it is actually used. In fact, OpenBSD is so secure that it was once banned in the DEF CON contest, in which the cracked masters attacked all other systems.

Berkeley Software Distribution (BSD) is one of the oldest and most popular versions of UNIX. Now it is divided into many different versions, with three of the more common open source distributions:

Although FreeBSD is the most widely used in these three releases, each version has a significant advantage, making it an important decision to choose the right solution. FreeBSD is the most common system in the three, and is widely used in i386 environment. When security becomes the most important consideration, OpenBSD is the appropriate distribution. NetBSD provides a small, highly portable choice that can run in a variety of architectures.
