Ever since people started to connect computer systems together (be it via local area networks, wide area networks or the internet) the issue of IT Security has become a matter of concern for everyone, including the home user all the way up to the global enterprise. Without a comprehensive information security strategy individuals and organization are at risk of compromised confidential data and loss of business as a result of malicious damage to operating systems and data.
Security+ Essentials is designed to provide the knowledge needed by IT professionals to pass the CompTIA Security+ exam. That said, the book is also of considerable use to anyone with a need to understand the concepts involved in creating and maintaining a secure IT environment.
Security+ Essentials is largely a platform agnostic book and as such many of the concepts described apply equally to a range of popular operating systems including Windows, Linux, MacOS X and UNIX.
On completion of this book it is intended that the reader will have a clear understanding of both the threats faced by IT infrastructures together with a basic understanding of the steps involved in planning and implementing a comprehensive multi-layered IT security strategy.
