Framework overlap

Does ISO 27019 cover New Zealand Information Security Manual (NZISM)?

You hold ISO 27019 and have been told to do New Zealand Information Security Manual (NZISM). Here is how much overlaps, control by control.

50% of New Zealand Information Security Manual (NZISM) you already have

ISO 27019 already covers about 50% of New Zealand Information Security Manual (NZISM), leaving 4 of 8 controls as genuinely new work.

Already covered 3 Likely covered 1 New work 4

What is genuinely new work

Nothing in ISO 27019 reaches these. This is the list to scope.

NZISM-4
Access Control, Authentication, and Communications Security
NZISM-6
Event Logging, Monitoring, Incident Response, and Business Continuity
NZISM-7
Media Handling, Outsourcing, Cloud Services, and Remote Access
NZISM-8
Security Risk Management, Vulnerability Management, and Incident Reporting
Show the 4 you already have
NZISM-1
NZISM Governance, Documentation, and Classification System
NZISM-3
Personnel Security, Physical Security, and Cryptography
NZISM-5
Network Security, System Hardening, and Application Security
NZISM-2
Certification and Accreditation (C&A) for Government Systems

How this is calculated

Already covered means a mapping runs from a control in ISO 27019 to that control. Likely covered means no direct mapping exists but both frameworks map to the same control in a third standard. New work means neither. We keep those separate rather than adding them into one friendlier number, because blending them would present a two-hop inference as a verified fact.

Coverage is not symmetric. Run it the other way and you will get a different number; both are correct.

From 332,959 cross-framework control mappings across 723 frameworks, 531 of them verified against their source documents. It does not tell you that you are compliant: a mapped control means the two standards ask for the same thing, not that you have done it.
