Framework overlap

Does ISO/IEC 27003:2017 cover Oman National Cybersecurity Framework?

You hold ISO/IEC 27003:2017 and have been told to do Oman National Cybersecurity Framework. Here is how much overlaps, control by control.

63% of Oman National Cybersecurity Framework you already have

ISO/IEC 27003:2017 already covers about 63% of Oman National Cybersecurity Framework, leaving 3 of 8 controls as genuinely new work.

Already covered 1 Likely covered 4 New work 3

What is genuinely new work

Nothing in ISO/IEC 27003:2017 reaches these. This is the list to scope.

OMANCS-1
Cybersecurity Governance, Policy, and Risk Management
OMANCS-2
Asset Management and Information Classification
OMANCS-8
Third-Party + Supply Chain Risk, Awareness Training, Physical Security, Compliance Audit
Show the 5 you already have
OMANCS-5
Network, Endpoint, System Development, and Configuration Security
OMANCS-3
Identity and Access Management, Authentication, Privileged Access
OMANCS-4
Data Protection, Cryptography, and Privacy Alignment
OMANCS-6
Security Monitoring, Detection, Incident Response, and OmanCERT Notification
OMANCS-7
Business Continuity, Disaster Recovery, and Resilience

How this is calculated

Already covered means a mapping runs from a control in ISO/IEC 27003:2017 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.
