Preparing Yourself for the CompTIA Security+ Exam
CompTIA Security+ Certification All-in-One Exam Guide is designed to help prepare you to take the CompTIA Security+ certification exam SY0-301. When you pass it, you will demonstrate that you have that basic understanding of security that employers are looking for. Passing this certification exam will not be an easy task, for you will need to learn many things to acquire that basic understanding of computer and network security.

How This Book Is Organized
The book is divided into sections and chapters to correspond with the objectives of the exam itself. Some of the chapters are more technical than others—reflecting the nature of the security environment, where you will be forced to deal with not only technical details but also other issues, such as security policies and procedures as well as training and education. Although many individuals involved in computer and network security have advanced degrees in math, computer science, information systems, or computer or electrical engineering, you do not need this technical background to address security effectively in your organization. You do not need to develop your own cryptographic algorithm; for example, you simply need to be able to understand how cryptography is used along with its strengths and weaknesses. As you progress in your studies, you will learn that many security problems are caused by the human element. The best technology in the world still ends up being placed in an environment where humans have the opportunity to foul things up—and all too often do.

Part I: Security Concepts: The book begins with an introduction to some of thebasic elements of security.

Part II: Cryptography and Applications: Cryptography is an important part of security, and this part covers this topic in detail. The purpose is not to make cryptographers out of readers but to instead provide a basic understanding of how cryptography works and what goes into a basic cryptographic scheme. An important subject in cryptography, and one that is essential for the reader to understand, is the creation of public key infrastructures, and this topic is covered as well.

Part III: Security in the Infrastructure: The next part concerns infrastructure issues. In this case, we are not referring to the critical infrastructures identified by the White House several years
