🔐 MACsec: Layer 2 Encryption for Modern Networks
When IPsec or TLS are too high in the stack, MACsec (IEEE 802.1AE) offers an efficient way to secure Ethernet frames at Layer 2—with low latency and line-rate performance.

In this post:
• How MACsec works (SCI, SAK, EAPoL)
• Trust model: Secure vs. insecure ports
• Hardware dependencies & deployment scope
• Typical use cases in data centers and enterprise access
