§2.7 – Security

Defense-in-depth approach: multiple layers of security

The openness of Ethernet guarantees easy access from anywhere in the world using readily available tools such as web browsers. This great advantage has implications for the security of networks across the enterprise.

PROFINET addresses these sometimes critical security issues in various ways, as defined in a special security specification:

  • By guarding against errors and improper operation
  • By preventing unauthorized access that could lead to network manipulation or espionage
  • By using proven and certified security standards (e.g. firewalls and VPN)

With these measures, the integrity of a PROFINET control network can be fully protected, without presenting any restrictions to personnel who rightfully needs access.
