+    MACsec is an IEEE standard (IEEE 802.1AE) for MAC security, introduced in
+    2006. It defines a way to establish a protocol independent connection
+    between two hosts with data confidentiality, authenticity and/or integrity,
+    using GCM-AES-128. MACsec operates on the Ethernet layer and as such is a
+    layer 2 protocol, which means it's designed to secure traffic within a
+    layer 2 network, including DHCP or ARP requests. It does not compete with
+    other security solutions such as IPsec (layer 3) or TLS (layer 4), as all
+    those solutions are used for their own specific use cases.
