The CISSP exam tests not only your technical foundation but also your management concepts. Many CISSP aspirants fail in Domain 1, 2, 6, or 7. It can be an indicator that they may not have connected the dots, e.g., information security governance, risk management, strategic management, project/program management, business continuity, etc.
My book, The Effective CISSP: Security and Risk Management, introduces those concepts that can help you build a solid foundation of information security from the perspective of information systems, business processes, and the organization.
If you have just started your CISSP or CISM (yes, CISM) journey, lost in the jungle of knowledge, or even failed in any of the domains mentioned above, The Effective CISSP: Security and Risk Management will make it straight.
