MACsec(Media Access Control Security) is aLayer 2 security protocolthat provides end-to-end encryption for Ethernet frames. It ensuresconfidentiality, integrity, and authenticityof data on wired networks.
A (Service data encryption):Encrypts Ethernet frames to protect against eavesdropping.
B (Data frame integrity check):Prevents data tampering and corruption.
C (Replay protection):Detects and prevents replay attacks by using unique sequence numbers.
D (Data source authenticity verification):Ensures that received data is from a legitimate source by using cryptographic authentication.
