ANSSI Guide d'hygiene informatique (42 mesures, v2.0) covers 14.9% of C5 (Germany)

18 of the 121 controls in C5 (Germany) are already satisfied by evidence you collected for ANSSI Guide d'hygiene informatique (42 mesures, v2.0). 103 are genuine gaps. Every claim below was judged against both control sets and then argued against; the ones that did not survive are published further down with the reason each failed.

This number is directional. It says how much of C5 (Germany) your ANSSI Guide d'hygiene informatique (42 mesures, v2.0) evidence satisfies. The reverse pair is a different number, often very different, because a security standard has enormous depth for access control and almost none for lawful basis or data subject rights.

55 candidate mappings were examined and 0 were removed. Signed off 2026-08-19, review level machine verified. Mappings were judged by Claude Code rather than read line by line by a practitioner. Every claim shows its reasoning so you can check it. Ask and a practitioner will review this pair.

Where the gaps are

Coverage is never evenly spread. A source standard usually satisfies one part of a target almost completely and barely touches another, and which part is which is the thing worth knowing before you plan the work.

Theme level, not control level, deliberately. The per-control list of what is evidenced and what is a gap is the report itself, so publishing it here would be publishing the thing being sold.

Claims that held

A sample. Each one names the control whose evidence does the work, the control it satisfies, and why.

mesure 23C5-COS-03argued against and upheld
Monitoring of connections in the Cloud Service Provider's network

Internet facing services placed in a partitioned zone away from trusted networks.

mesure 19C5-COS-03argued against and upheld
Monitoring of connections in the Cloud Service Provider's network

Network segmented into zones with partitioning enforced between them.

mesure 25C5-COS-04argued against and upheld
Cross-network access

Dedicated partner interconnections secured so cross network access stays limited and controlled.

mesure 22C5-COS-04argued against and upheld
Cross-network access

Perimeter internet access routed through a secure filtering and logging gateway.

mesure 28C5-COS-05argued against and upheld
Networks for administration

Administration performed on a dedicated network partitioned from ordinary networks.

mesure 4C5-COS-07argued against and upheld
Documentation of the network topology

An up to date network diagram of the information system is maintained.

mesure 21C5-CRY-02argued against and upheld
Encryption of data for transmission (transport encryption)

Secure version of a protocol used wherever one exists, protecting traffic in transit.

mesure 18C5-CRY-02argued against and upheld
Encryption of data for transmission (transport encryption)

Sensitive data transmitted over the internet encrypted using recommended cryptographic mechanisms.

Claims that did not hold

Nothing proposed for this pair was rejected in review. That is unusual and worth knowing rather than hiding: it means the candidate set was small and every candidate held.
