Klappentext
Offers a unique, insider perspective on building secure systems using OpenBSD--the world's most secure operating system. OpenBSD download servers handle more than 6,000 downloads per month. Jose Nazario is known in the OpenBSD community for running the most important community forum, located at www.deadly.org, and as key developer for the project. Allows security minded sys admins to move to a more secure operating system and provides seasoned OpenBSD users with details to improve their work. The OpenBSD operating system is a secure, stable, and powerful operating system that is attracting many new and old UNIX users to it. The OS is well designed for both workstation and server use. OpenBSD supports many mainstream applications and also offers great hardware support. Since OpenBSD doesn't have many of the business pressures of increasing sales and trendy gimmicks that Linux and other BSD systems have, it is able to be designed on technical merit. This means that while the system works very well, it isn't targeted at the user who wants to be able to "point and click" and not read the documentation. This book is written to help new users understand the features of the OpenBSD system and to give more seasoned users the education to fully exploit all that OpenBSD has to offer. ***The topic of security is sprinkled throughout every chapter, because this is how security is best done. A chapter or two at the end of a book simply cannot demonstrate how OpenBSD has integrated security into almost every facet of the system.
