How master ISO 27001

Answer: I can suggest you the following path:

- Our free online training ISO 27001 Foundations Course https://advisera.com/training/iso-27001-foundations-course/ where you can get the basics of the standard.
- Book Secure & Simple: A Small-Business Guide to Implementing ISO 27001 On Your Own https://advisera.com/books/secure-and-simple-a-small-business-guide-to-implementing-iso-27001-on-your-own/
- The standard itself https://www.iso.org/iso/catalogue_detail?csnumber=54534

I suggested this course of action because you start your learning at no cost with the free training , expend less than the cost of the standard with the book, which is written having beginners in mind, and finishes with the standard itself when you already have learned enough to make a better use of its requirements and recommendations.
