BSI IT-Grundschutz — the German security baseline

The de-facto framework for NIS2-regulated German entities: modular Bausteine across ISMS, organisation, operations, detection and infrastructure.

What is BSI IT-Grundschutz?

IT-Grundschutz is the methodology of the German Federal Office for Information Security (BSI). It provides a structured baseline of security requirements organised into Bausteine (building blocks) that cover the whole organisation, from management to technical systems.

It is widely used by German public and private organisations and aligns naturally with ISO 27001 — IT-Grundschutz can even lead to an ISO 27001 certificate on the basis of IT-Grundschutz.

IT-Grundschutz Baustein layers

ISMS & ORP

Security management, organisation, personnel, identity and access management.

CON & OPS

Cryptography, backup, secure development; standard operations, patching, malware protection, logging.

DER

Detection of security events, incident handling, forensics, business continuity.

APP, SYS, NET, INF, IND

Applications, servers/clients, networks, physical infrastructure and industrial (OT).

Frequently asked questions

What is BSI IT-Grundschutz?

A German security baseline from the BSI, organised into Bausteine (building blocks) across process and system layers, widely used for NIS2 and ISO 27001 alignment.

How does IT-Grundschutz relate to ISO 27001?

IT-Grundschutz is compatible with ISO 27001 and can lead to certification 'on the basis of IT-Grundschutz'. ResiPlan cross-maps the two.

Other frameworks

ResiPlan covers 10 frameworks with cross-mapping: assess once, prove everywhere.
