How PKI Supports Compliance Requirements
Requirements such as NIS2, DORA or KRITIS frameworks demand state-of-the-art safeguards, traceable processes and reliable evidence. PKI is a key building block because it enables authenticity, integrity and encrypted communication at scale—provided the certificate lifecycle (CLM) is managed and keys are adequately protected (e.g., using HSMs).
Practical PKI Relevance
- ✓AuthenticitymTLS and client certificates for unambiguous identification of devices/services.
- ✓IntegritySignatures (including code signing and documents) provide proof of origin and integrity.
- ✓ConfidentialityTLS/HTTPS as the standard for encryption in transit (external and internal).
- ✓GovernanceCLM: policies, approvals, audit trail, rotation/revocation, and reports as evidence.
- ✓Key‑CustodyHSM: protection of private keys, role models, quorum/M-of-N, and logging.
Typical Evidence (Artifacts)
Audit‑Trail
Evidence of who requested, issued, renewed, or revoked certificates and when.
Policy‑Evidence
Documented policies (SAN constraints, validity periods, algorithms, environment rules).
Outage Prevention
Monitoring and automated renewal as a contribution to operational resilience.
HSM Controls
Key generation in the HSM, dual control, separated roles, as well as logging and reviews.
Note
This content does not constitute legal advice. Legal and compliance teams should be involved for binding interpretation and implementation.
NIS2
Strengthens requirements for risk management, governance, and reporting mechanisms. PKI/CLM support secure communication, strong authentication, and auditable processes.
DORA
Focus on ICT risk management, resilience testing, and third-party risk. PKI/CLM provide technical controls and evidence artifacts.
KRITIS (DE)
Requires appropriate technical and organizational measures. PKI and HSM-backed key processes are typical building blocks for traceable security controls.
TISAX
Assessment mechanism for information security in the automotive supply chain. PKI supports partner trust, secure communication, and signatures (e.g., software updates).
