Prepare ISO 27001: From protection needs to effective ISMS
By Nico Freitag, Geschäftsführer, Cybersecurity und Governance
ISO/IEC 27001 defines requirements for an information security management system. Good preparation begins with scope, accountability, values and risks. Documents follow the actual process and not the other way around.
What needs to be determined first?
The scope determines which organizational parts, processes, systems and interfaces the management system covers. It must fit the business activity and must not artificially ignore critical dependencies. Management is responsible for goals and resources.
How is reliable risk treatment created?
Assets, threats, vulnerabilities and impacts are assessed using a consistent method. Those responsible for measures receive dates and reasons. Residual risks are consciously accepted and not silently overlooked.
When does certification make sense?
Certification can support customer requirements or tenders. But an ISMS should first manage its own security. The ISO describes ISO/IEC 27001 as a risk management system that can be adapted to size and needs.
