Adoption of ISO 27031

Answer:

ISO 27031 is a supporting standard to help implement controls from ISO 27001 Annex A section 17, which basically covers continuity of information security and Information and Communication Technologies. Considering that, ISO 22301 covers the continuity of business as a whole, while ISO 27031 can be seen as a tool to implement the technical part of ISO 22301, so implementing it without ISO 22301 wouldn't be a good approach, because you wouldn't take advantage of the business impact analysis process, which helps optimize resources application.
