The point: The BSI module NET.3.2 prescribes requirements for firewall rule sets, administrative access, logging, and system hardening.
The BSI defines in module NET.3.2 concrete requirements for the secure operation of firewalls. Central points are rule sets, administration, logging, and system hardening.
Module NET.3.2 of the Federal Office for Information Security establishes binding requirements for the secure operation of firewalls. These comprise four central dimensions: the management of filter rules and their documentation, the control of administrative access, the logging of security events, and the technical hardening of the firewall systems themselves.
For CISOs, this means that firewall operation must not be isolated, but integrated into a coherent security framework. BSI requirements address both technical configuration and organizational processes surrounding firewall management — from change control over rule bases to auditability.
Compliance with NET.3.2 forms a foundation for responsibly managed network perimeters and creates traceable documentation in the event of security incidents or audits.
