Transport Layer Security / Secure Sockets Layer (TLS/SSL) is een begrip binnen de industriële digitalisering en extra industrie & security topics.
Definitie
Transport Layer Security (TLS) / Secure Sockets Layer (SSL) zijn cryptografische protocollen die veilige communicatie mogelijk maken over computernetwerken. In industriële omgevingen worden ze gebruikt voor het beveiligen van data-uitwisseling tussen MES, ERP, IoT apparaten en andere kritieke systemen.
Kenmerken
- Data encryption: Cryptographic protection van data in transit
- Authentication: Verification van communicating parties identity
- Data integrity: Detection van data tampering tijdens transmission
- Certificate-based security: Public key infrastructure (PKI) voor identity verification
- Protocol versioning: TLS 1.2, TLS 1.3 voor modern security requirements
- Perfect Forward Secrecy: Session keys remain secure na private key compromise
- Cipher suite negotiation: Automatic selection van encryption algorithms
- Legacy SSL support: Backward compatibility voor older industrial systems
