Common Industrial Protocol (CIP™) Security is an open-standard secure communication protocol developed by ODVA for EtherNet/IP™ communications, providing the final layer of defense for protection against malicious communication attacks.
CIP Security™ can play an important part of a defense in depth strategy, helping to fortify control system cybersecurity by providing data authenticity, integrity, and confidentiality by:
- Using Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS) cryptographic protocols providing secure transport of EtherNet/IP traffic
- Using keyed-Hashed Message Authentication Code (HMAC) providing data integrity and message authenticity
- Using X.509v3 Digital Certificates providing cryptographically secure identities to devices
