Best practices for testing the performance of MACsec under real world conditions
Ethernet is the foundation of modern connectivity, but traditional security protocols like IPsec and TLS do not protect data at the Ethernet (Layer 2) level. MACsec (IEEE 802.1AE) addresses this gap by providing encryption and authentication directly on Ethernet links, ensuring secure, low-latency data transmission.
To ensure MACsec performs as intended, rigorous testing is essential. This includes validating functionality (e.g., encryption, key rollover, replay protection), assessing performance at wire speed (latency, jitter, throughput), and conducting negative testing to simulate failures and attacks.
The White Paper explains MACsec’s role in securing networks, outlines best practices for comprehensive testing under real-world conditions, and highlights how Teledyne LeCroy solutions enable accurate validation without compromising performance.
