I purchased this book new and studied with sticky notes, so there are no markings in the book. The condition is good, but the cover has some minor scratches from use. I passed the exam with this book and the app, so I highly recommend it! This is a study guide for Information Security Management. It's the 2025 edition and corresponds to Syllabus Ver. 4.0. It has easy-to-understand illustrations and provides guidance on how to solve practical problems for Subject B. It comes with a past exam app (DEKIDAS-WEB) that includes over 14 sets of exam questions.
