The Security+ Exam Guide provides exam candidates with the concepts, objectives, and test-taking skills needed to pass on their first attempt. Instead of covering every computer security topic, this book isolates those topics most likely to be addressed on the exam. Written by an experienced network administrator and CompTIA certified instructor, the book draws upon subject expertise and teaching experience to provide everything test takers need to know for successful test taking.
