This study guide for the CISSP exam (Certified Information Systems Security Professional) is also well suited as a general text book for information security.
The 8th edition will be published in October 2018. It is possible to use the 7th edition from 2016, but we recommended to wait until October and buy the 8th edition. Until then the lecture notes and other learning material will be sufficient for studying this course.
The book can be bought from e.g. Amazon.com or from the publisher McGrawHill.
