Like all ISO standards, ISO/IEC 27001 is not freely available, but is subject to the license of the International Organization for Standardization (ISO). For example, if you want to download the main ISO/IEC 27001 and ISO/IEC 27002 documents as PDF versions, you will have to pay fees of around 300 euros. As far as our ISO 27001 training courses are concerned: The training price of the mITSM course ISMS Security Officer according to ISO 27001 includes the „Praxisbuch ISO/IEC 27001“ by Dr. Michael Brenner, with all essential parts of DIN ISO/IEC 27001 in text form.
