CompTIA's Security+ certification is a globally-recognized, vendor neutral exam that has helped over 60,000 IT professionals reach further and higher in their careers. The current Security+ exam (SY0-201) focuses more on being able to deal with security issues rather than just identifying them. The new exam covers six major topics: Systems Security, Network Infrastructure, Access Control, Assessments and Audits, Cryptography, and Organizational Security. This third edition has been updated to follow and cover the new exam objectives. After reading this book not only will you be able to pass the exam but you will have a working knowledge of cryptography, security legislation, vulnerability assessments, logical access control methods, and much more. This complete exam-prep package includes full coverage of new Security+ objectives and two complete practice exams. It is authored by a leading Microsoft security expert. A good reference for both beginning security professionals and a seasoned IT person, this book goes beyond the exam objectives to cover the technology, and how that technology is currently being deployed in the business world and what the future of the technology may be. These insights provide the reader a look 'inside' security, both today and in the future.
