description	[COMMUNITY] Assess Austrian NISG 2026 obligations (BGBl. I Nr. 94/2025, in force 1 Oct 2026) — AT transposition of NIS2, Cybersicherheitsbehörde registration, CSIRT incident reporting, KSÖ coordination, and Austrian sectoral rules for Essential/Important entities

⚠️ Community-contributed command — not part of the officially-maintained ArcKit baseline. Output should be reviewed by qualified CISO / Cybersicherheitsbehörde-liaison / Rechtsabteilung before reliance. Citations to the Cybersicherheitsbehörde / A-SIT / EU regulations may lag the current text — verify against the source. Items marked [NEEDS VERIFICATION] must be confirmed against the enacted NISG 2026 text (BGBl. I Nr. 94/2025) and its implementing ordinances (Verordnungen) before external use — the law is newly enacted and its ordinances are still forthcoming.

You are helping an enterprise architect generate an Austrian NISG 2026 Compliance Assessment — the Austrian transposition of NIS2 (EU Directive 2022/2555). The Netz- und Informationssystemsicherheitsgesetz 2026 (NISG 2026, BGBl. I Nr. 94/2025) is a standalone act (not a mere amendment of the NISG 2018). It was passed on 12 December 2025, published on 23 December 2025, and enters into force on 1 October 2026 (§51); it replaces the NISG 2018, which expires on 30 September 2026. Essential/Important entities must register with the Cybersicherheitsbehörde within three months of entry into force — i.e. by end-December 2026 (§29 Abs. 3) — and submit the first Selbstdeklaration of implemented risk-management measures within twelve months of the registration duty, i.e. by 30 September 2027 (§33 Abs. 1). The independent Wirksamkeitsnachweis (§33 Abs. 2) is a separate, later obligation: the Cybersicherheitsbehörde may first request it no earlier than two years after entry into force (from October 2028). Once requested, the general window is two years to evidence technical, operational and organisational implementation via an independent body — but Essential entities must evidence the operative and organisational implementation within two months of the request (§33 Abs. 2 second sentence); for Important entities §38 Abs. 2 applies analogously. Run this after $arckit-eu-nis2 to add Austrian obligations that go beyond the EU baseline.

User Input

$ARGUMENTS

Instructions

Note: Before generating, scan projects/ for existing project directories. For each project, list all ARC-*.md artifacts, check external/ for reference documents, and check 000-global/ for cross-project policies. If no external docs exist but they would improve output, ask the user.

Step 0: Read existing artifacts from the project context

MANDATORY (warn if missing):

• REQ (Requirements) — Extract: security requirements (NFR-SEC-xxx), operational requirements, integration requirements (INT-xxx), sector and entity type information, criticality thresholds
  • If missing: proceed with user-provided entity description, but note that requirements analysis would strengthen the gap assessment

RECOMMENDED (read if available, note if missing):

• NIS2 (EU NIS2 Assessment) — Extract: Annex I / Annex II classification, size threshold results, Article 21 ten-measure status, incident reporting baseline
  • If missing: warn that $arckit-at-nisg should be run after $arckit-eu-nis2 for best results
• RISK (Risk Register) — Extract: existing security risks, supply chain risks, third-party risks, business continuity risks
• SECD (Secure by Design) — Extract: existing security controls, maturity assessments, security architecture decisions
• PRIN (Architecture Principles, 000-global) — Extract: security baseline, incident response principles, supply chain policy

OPTIONAL (read if available, skip silently):

• ATDSG (AT DSG Assessment) — Extract: overlap where security monitoring processes personal data
• DORA (DORA Assessment) — Extract: overlapping ICT resilience obligations if financial sector

Step 0b: Read external documents and policies

• Read any external documents in external/ — extract existing Cybersicherheitsbehörde / CSIRT / A-SIT correspondence (and any legacy BMI/GovCERT correspondence under the NISG 2018), sector-specific designation letters, incident response plans, BCM plans, Sicherheitshandbuch excerpts
• Read any global policies in 000-global/policies/ — extract security policy, incident response policy, supplier security policy, BCM policy
• If BMI designation documents found, use them to pre-populate the Essential/Important status.

Step 1: Identify or Create Project

Identify the target project from the hook context. If the project doesn't exist:

1. Use Glob to list projects/*/ directories and find the highest NNN-* number
2. Calculate the next number (zero-padded to 3 digits)
3. Slugify the project name
4. Use the Write tool to create projects/{NNN}-{slug}/README.md
5. Set PROJECT_ID and PROJECT_PATH

Step 2: Read Source Artifacts

Read all documents from Step 0. Identify:

• Sector (NIS2 Annex I Essential / Annex II Important / out of scope)
• Organisation size (>250 employees / 50–250 / <50)
• Operation in Austria (seat, subsidiary, critical service delivery in AT)
• Sector context (energy, finance, health, transport, digital infrastructure, public administration). Under NISG 2026 the Cybersicherheitsbehörde (Bundesamt für Cybersicherheit) is the single competent authority for registration, supervision and enforcement; sectoral regulators (E-Control, FMA, etc.) retain their domain-specific roles but do not run NIS supervision separately [NEEDS VERIFICATION: confirm any sector-specific competences retained under the enacted NISG 2026]
• Financial sector involvement (DORA overlap)

Step 3: Template Reading

Read the template (with user override support):

• First, check if .arckit/templates-custom/at-nisg-template.md exists in the project root
• If found: Read the user's customized template
• If not found: Read .arckit/templates/at-nisg-template.md
• Then read .arckit/templates/_partials/RENDERING.md and resolve the <!-- DOC-CONTROL-HEADER --> marker in the template before writing. ATNISG carries the Austria regime, which hard-routes to _partials/document-control-at.md whatever the operator's user config says.

Step 4: Entity Classification (Austrian specifics)

Before generating the assessment, determine entity classification:

Annex I — Essential Entities (NIS2 baseline, carried into NISG): Energy, Transport, Banking, Financial market infrastructure, Health, Drinking water, Wastewater, Digital infrastructure, ICT service management, Public administration, Space.

Annex II — Important Entities (NIS2 baseline): Postal/courier, Waste, Chemicals, Food, Manufacturing (medical devices, computers, transport), Digital providers, Research.

Austrian additions or scope differences:

• Austria may designate additional entities beyond the size thresholds where criticality warrants it — the Cybersicherheitsbehörde issues a Bescheid on the criticality grounds in §26 (Größenunabhängige Einstufung; §26 Abs. 3: sole national provider of an essential service, material impact on public order / safety / health, systemic risk, or particular national/regional significance for the sector)
• Public-administration scope: federal bodies are in scope; the treatment of Land-level bodies (federal-only vs opt-in) must be confirmed against the enacted text [NEEDS VERIFICATION: confirm Länder scope / any Landeshauptmann opt-in and its §]
• Transition from NISG 2018: the NISG 2018 expires on 30 September 2026 and entities previously designated as Betreiber wesentlicher Dienste must be re-assessed against the new Essential/Important classification; NISG 2026 obligations apply from entry into force (1 October 2026) [NEEDS VERIFICATION: confirm transitional provisions and their § in the enacted text]

Size thresholds (NIS2 carried into NISG):

• Essential Entity: sector-qualified AND (>250 employees OR >€50M revenue)
• Important Entity: sector-qualified AND (50–250 employees OR €10–50M revenue)
• Microenterprises may fall out of scope unless sector-specific designation applies

Show entity classification before generating the full document.

Step 5: Generate NISG Assessment

CRITICAL: Use the Write tool to create the assessment document.

1. Detect version: Check for existing ARC-{PROJECT_ID}-ATNISG-v*.md files:

   • No existing file → VERSION="1.0"
   • Existing file → minor increment if refreshed, major if scope changed

2. Auto-populate Document Control:

   • Document ID: ARC-{PROJECT_ID}-ATNISG-v{VERSION}
   • Status: DRAFT
   • Created Date: {current_date}
   • Next Review Date: {current_date + 12 months}
   • Entity Designation: from Step 4 classification
   • Note: "This document supplements ARC-{PROJECT_ID}-NIS2-v*.md with Austrian-specific NISG 2026 obligations"

3. Section 1: Austrian Scope and Designation

   • Sector classification (sectors in Anlagen 1/2). Competent authority under NISG 2026 is the Cybersicherheitsbehörde (Bundesamt für Cybersicherheit, §3a); note any retained sectoral roles [NEEDS VERIFICATION]
   • Entity designation: Essential / Important / Out of scope (§24)
   • Previous NISG 2018 designation (Betreiber wesentlicher Dienste) and re-assessment against the new classification (NISG 2018 expires 30 Sep 2026)
   • Cross-border operations treatment (main establishment rules from NIS2)
   • Federal vs Land competence — confirm scope for Land-level bodies [NEEDS VERIFICATION]

4. Section 2: Governance (NIS2 Art. 20 — as transposed)

   • Geschäftsleitung (management body) approval of security measures
   • Management body responsibility to steer and oversee cybersecurity (§31). Note: the NISG 2026 does not create explicit personal liability of the Leitungsorgane — administrative fines under §45 are addressed to the legal person (juristische Person / eingetragene Personengesellschaft) through the attribution rules in §44, and §44 Abs. 5 directs that punishment of a natural responsible person under §9 VStG be waived once the entity itself is fined for the same breach
   • Management body cybersecurity training requirement
   • Compliance status for each obligation

5. Section 3: Risk Management Measures (NIS2 Art. 21 — as transposed)

   • All ten minimum security measures with current status and gaps:
     1. Risk analysis policy
     2. Incident handling
     3. Business continuity / BCM
     4. Supply chain security
     5. Secure acquisition, development, maintenance

Before writing the file, read .arckit/references/quality-checklist.md and verify all Common Checks pass.

Write the document to:

projects/{project_id}/ARC-{PROJECT_ID}-ATNISG-v{VERSION}.md

Important Notes

• Run after eu-nis2: This command adds the Austrian layer. For best results, run $arckit-eu-nis2 first.
• NISG 2026 is newly enacted and not yet in force: The transposition (NISG 2026, BGBl. I Nr. 94/2025) enters into force on 1 October 2026 (§51) and replaces the NISG 2018 (expires 30 Sep 2026). Implementing ordinances (Verordnungen) are still forthcoming. Key deadlines: registration within three months of entry into force (§29 Abs. 3, ~end-December 2026); first Selbstdeklaration of implemented measures within twelve months of the registration duty (by 30 September 2027, §33 Abs. 1); the independent Wirksamkeitsnachweis (§33 Abs. 2) is requestable by the authority no earlier than two years after entry into force (from October 2028), and once requested Essential entities have only two months to evidence operative and organisational implementation (general window two years for the full technical/operative/organisational proof). An AT cyber practitioner must confirm before external reliance.
• Management body duties (not personal liability): NIS2 Art. 20 (transposed in §31) makes the Geschäftsleitung responsible for steering and overseeing cybersecurity measures and requires management-body training. Note that the NISG 2026 does not create explicit personal liability of management bodies — administrative fines under §45 are addressed to the entity as a legal person (attribution via §44; §44 Abs. 5 waives §9 VStG personal punishment once the entity is fined). Core-duty ceilings (§45 Abs. 1): Essential up to €10M / 2% turnover (§45 Abs. 2), Important up to €7M / 1.4% (§45 Abs. 3); procedural breaches carry a lower tier of up to €50K (€100K repeat) under §45 Abs. 4.
• Public-administration bodies are not fined: §46 applies "abweichend von § 45" to Behörden and sonstige Stellen der öffentlichen Verwaltung (including Gebietskörperschaften and bodies constituted under private law). The consequence is a Bescheid establishing non-compliance plus a remediation deadline, and — if unremedied once the Bescheid is final — publication of the non-compliance (§46 Abs. 2, Verfassungsbestimmung). Never quote the §45 Abs. 2/3 monetary ceilings as a public-administration entity's exposure.
• Ne bis in idem with the GDPR: if the Datenschutzbehörde has already fined the same conduct under Art. 58(2)(i) GDPR, no NISG fine may follow (§44 Abs. 7).
• 24-hour reporting capability: The 24-hour early warning window is tight. Flag if no 24/7 incident detection and reporting capability exists.
• KSÖ is voluntary but strategic: Participation in Kuratorium Sicheres Österreich is not a legal obligation, but it is the main national PPP forum and is often expected of designated entities.

Success Criteria

• ✅ Assessment document created at projects/{project_id}/ARC-{PROJECT_ID}-ATNISG-v{VERSION}.md
