IEEE 802.1AE
IEEE 802.1AE, known as MAC Security (MACsec), is a standard that provides secure communication over Ethernet networks. It encrypts and authenticates data traffic at the data link layer, ensuring that information remains confidential and unaltered as it travels between devices. MACsec helps protect against eavesdropping, tampering, and man-in-the-middle attacks on wired network connections. It is commonly used in enterprise and data center environments to enhance both security and data integrity, making local network communications more secure without impacting performance or requiring significant network changes.
