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 against malicious communication attacks commonly carried out over large organizational networks.
CIP Security™ can play an important part of a defense-in-depth strategy by:
- Using Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS) cryptographic protocols, for secure transport of EtherNet/IP traffic
- Using keyed-Hashed Message Authentication Code (HMAC), for data integrity and message authenticity
- Using X.509v3 digital certificates, for cryptographically secured identities to devices
