NIS2 Section 30 BSIG: All 10 Obligations in One Overview
TL;DR
- All 10 areas are mandatory; depth scales with risk
- ISO 27001 covers 9 of 10; supply-chain security needs additional structure
- Designed for board briefings: one page, plain language
- Section 30 BSIG (German Cybersecurity Act) is the operational hinge of NIS2 in Germany
- Companion deadlines: 24/72/30 incident reporting in Section 32 BSIG
1. Risk-management system
Documented methodology (e.g., ISO 27005), annual update cycle, risk treatment plan with owners and target dates, and management approval.
2. Incident response
Incident-response plan, named crisis team, tabletop exercises, and the 24/72/30 BSI reporting workflow ready to execute.
3. Business continuity and disaster recovery
Business Impact Analysis, RTO/RPO targets per critical process, emergency plan, and annual DR tests with restore evidence.
4. Supply-chain security
Supplier inventory with criticality scoring, audit rights and DPA clauses, top-20 supplier audits, and exit plans for critical providers.
5. Secure system acquisition and maintenance
Patch management with documented SLAs, vulnerability scans, hardening standards (CIS Benchmarks, BSI baseline).
6. Effectiveness assessment of cybersecurity controls
Internal audits, external penetration tests, optional ISO 27001 audit, and CAPA tracking on findings.
7. Training and awareness
Annual cybersecurity training for all staff, plus quarterly phishing simulations. Records retained as audit evidence.
8. Cryptography and access management
MFA on all administrative access, conditional access policies, IAM lifecycle, and PAM for privileged accounts.
9. Asset management
Inventory of hardware, software, data, and cloud services; classification scheme; BYOD policy; end-of-life management.
10. Secure authentication and communication
FIDO2 / passkeys, encrypted communication channels, zero-trust architecture for network access.
Summary
Section 30 BSIG is a checklist disguised as a law. Treat it as a coverage matrix: every area must be addressed; ISO 27001 covers most; the gap is supply chain and visible board engagement. The NIS2 Kit ships templates for each of the 10 areas.
