VS-NFD Access Control Systems

The VS-NfD directive requires that only personnel with appropriate clearance and operational need (need-to-know principle) gain access to classified information. In practice this means: unambiguous identification and authentication of all users, role-based access control, regular review of permissions, and comprehensive audit logging of all access. ADVISORI supports you with both the technical and organisational implementation of these requirements, from access rights design through to monitoring system setup.

Technical enforcement of the need-to-know principle operates on multiple levels: Role-based access control (RBAC) ensures each employee can only access the classified information required for their duties. Multi-factor authentication (MFA) prevents unauthorised access. Privileged access management limits and monitors administrator access. Automatic revocation rules deactivate permissions when roles change or staff leave. ADVISORI designs these measures to comply with BSI requirements and integrate with your existing IT infrastructure.

IT systems that store, process or transmit classified information at VS-NfD level must meet BSI requirements. This applies particularly to encryption solutions, VPN systems, mobile devices and storage media. The BSI maintains a list of approved products. ADVISORI advises you on selecting BSI-approved components and integrating them into your access control system to meet all VS-NfD directive and VSA requirements.

Audit logging covers the complete recording of all access to VS-NfD classified information: who accessed which classified document, when, what action was performed and from which device. These audit trails must be stored tamper-proof and regularly evaluated. ADVISORI sets up logging systems that meet Classified Information Protection Manual requirements and enable rapid analysis in the event of security incidents.

During a security clearance check under the Security Clearance Act (SÜG), inspectors verify whether the organisation has implemented appropriate technical and organisational access control measures. This includes correct implementation of the need-to-know principle, effectiveness of authentication procedures, completeness of audit logging, and regular review of permissions. ADVISORI prepares you for these inspections and ensures your access control systems meet all requirements.

For VS-NfD (For Official Use Only) the baseline requirements of the VS-NfD directive apply: access control, encryption and audit logging. At higher levels such as VS-Confidential or Secret, requirements tighten considerably: level

2 or

3 security clearance checks, physically separated IT systems, enhanced physical security measures and stricter storage requirements. ADVISORI advises you regardless of classification level and scales access control measures to match the respective requirements.

Integration proceeds step by step: first we analyse your existing IT landscape and identify VS-NfD-relevant systems and data flows. We then design an access rights concept that integrates with existing directory services (Active Directory, LDAP) and authentication systems. Implementation covers setting up multi-factor authentication, configuring role-based access rules and connecting to audit logging systems. This avoids parallel structures and ensures VS-NfD access control integrates seamlessly into your processes.
