MACsec encryption
Defines MACsec encryption as a Layer 2 security technology that protects physical media from common attacks, provides data confidentiality and integrity, and details its benefits, hardware support, and deployment models.
Key concepts for MACsec encryption
Describes essential MACsec components including the MKA protocol, Pre-shared Keys, CKN, CAK, Secure Association Keys, key server roles, and policy parameters that govern secure Ethernet link communication.
How MACsec encryption works
Describes the workflow of MACsec encryption, covering link establishment, peer authentication, connectivity association formation, key server selection, and the secure exchange of encrypted data frames.
Guidelines for MACsec encryption
Provides operational guidelines for ensuring reliable MACsec encryption, including recommendations for keychain management, fallback PSK configuration, and consistent interface application to prevent security gaps.
Configure MACsec encryption
Configure MACsec encryption by establishing a security keychain and defining a custom policy to protect data across your physical network interfaces
