What is MACsec cisco?

MACsec is the IEEE 802.1AE standard for authenticating and encrypting packets between two MACsec-capable devices. The Catalyst switches support 802.1AE encryption with MACsec Key Agreement (MKA) on downlink ports for encryption between the switch and host devices.

Why use MACsec?

MACsec provides point-to-point security on Ethernet links between directly connected nodes and is capable of identifying and preventing most security threats, including denial of service, intrusion, man-in-the-middle, masquerading, passive wiretapping, and playback attacks.

How do I configure MACsec?

To configure MACsec, you follow these steps:

1. ∎ Step 1: Enable MACsec hardware support.
2. ∎ Step 2: Create an MKA policy.
3. ∎ Step 3: Add a pre-shared key (CAK) to the interface.
4. ∎ Step 4: Add the MKA policy and enable MACsec protection on the port.
5. ∎ Step 5: Control egress traffic rate.
6. ∎ Step 6: Verify MACsec configuration.

What is WAN MACsec?

WAN MACsec provides a line-rate network encryption solution over Layer 2 Ethernet transport services. MACsec is no longer just a LAN technology and can be leveraged outside campus networks, whether it be over Metro Ethernet transport or Data Center Interconnect (DCI) links.

Is MACsec better than IPsec?

IPsec works on IP packets, at layer 3, while MACsec operates at layer 2, on ethernet frames. Thus, MACsec can protect all DHCP and ARP traffic, which IPsec cannot secure. On the other hand, IPsec can work across routers, while MACsec is limited to a LAN.

What is IPsec and MACsec?

MACsec is for authentication and encryption of traffic over Ethernet on Layer 2 LAN networks. Alternatively, for Layer 3 networks, IPSec is used. Since MACsec and IPsec operate on different network layers, IPsec works on IP packets at Layer 3, while MACsec operates on Ethernet frames at Layer 2.

Is MACsec necessary?

MACsec: the foundation for network security One of the most compelling cases for MACsec is that it provides Layer 2 (OSI data link layer) security allowing it to safeguard network communications against a range of attacks including denial of service, intrusion, man-in-the-middle and eavesdropping.

What is Mka MACsec?

MKA is considered a control plane protocol to manage MACsec devices for proper data protection. The implementation is typically done in software. It is important to ensure proper MKA session establishment, peer authentication, key exchange, scale and performance, and interoperability.

Does AWS support MACsec?

AWS Direct Connect now supports MACsec security (IEEE 802.1AE), giving you a new option for securing your data from when it leaves your network until it arrives at AWS. With this release, Direct Connect delivers native, near line-rate, and point-to-point encryption for 10 Gbps and 100 Gbps links.
