Links are essential for sharing information and resources on the internet, but they can also pose security risks if they are not protected properly. Hackers can intercept, modify, or redirect your links to malicious sites or steal your data. That’s why you need a reliable and easy way to secure your links with 21197 Link Secure.

21197 Link Secure is a service that provides point-to-point security on Ethernet links using Media Access Control security (MACsec), which is defined by IEEE standard 802.1AE. MACsec ensures data integrity and encryption for all traffic traversing the link, preventing most common security threats such as denial of service, intrusion, man-in-the-middle, masquerading, passive wiretapping, and playback attacks. MACsec can also work with other security protocols, such as IP Security (IPsec) and Secure Sockets Layer (SSL), to provide end-to-end network security.

With 21197 Link Secure, you can easily configure MACsec on your interfaces using either manual or dynamic key exchange modes. You can also create connectivity associations, which are sets of MACsec attributes that define the secure channels for inbound and outbound traffic. You can monitor and manage your MACsec-secured links using the 21197 Link Secure dashboard, which shows you the status, statistics, and alerts of your links. You can also use the 21197 Link Secure API to integrate with your existing systems and applications.

21197 Link Secure is ideal for any scenario where you need to share sensitive or confidential data over Ethernet links, such as biotechnology firms, financial institutions, government agencies, or cloud providers. You can use 21197 Link Secure to update files securely, track and gather feedback from stakeholders, or share data and results with partners through a managed access program. 21197 Link Secure also supports Chrome security updates (89.0.4389.114) for Windows, Mac and Linux with fixes for 8 vulnerabilities, including CVE-2021-21197.

Benefits of MACsec

MACsec offers many benefits for securing data in motion over Ethernet links, such as:

• Line rate encryption: MACsec can encrypt and decrypt data at high bandwidths without affecting the performance or latency of the network . This is especially useful for applications that require large amounts of data transfer, such as cloud computing, video streaming, or online gaming.
• Flexible option: MACsec can be deployed in different ways compared to other cryptographic protocols such as TLS and IPsec. The algorithm used within the MACsec protocol is very suitable for high-speed hardware implementation and can be integrated into switches, routers, or network interface cards (NICs). MACsec can also work with different key management schemes, such as manual configuration, 802.1X authentication, or MKA (MACsec Key Agreement) protocol.
• Protection from attacks: MACsec can protect users’ traffic from various attacks that target the link layer, such as snooping, man-in-the-middle (MitM), masquerading, passive wiretapping, and playback attacks . MACsec appends a header and a tail to each Ethernet frame that contains a sequence number and an integrity check value (ICV). The receiving device verifies the ICV and the sequence number to ensure that the frame has not been tampered with or replayed. MACsec also optionally encrypts the payload of the frame to prevent unauthorized access to the data.

How to Use 21197 Link Secure

If you want to use 21197 Link Secure to secure your links with MACsec, you need to follow these steps:

1. Sign up: You need to create an account on the 21197 Link Secure website and choose a subscription plan that suits your needs. You can also request a free trial to test the service before committing.
2. Configure: You need to configure your devices to enable MACsec on the interfaces that you want to secure. You can use either manual or dynamic key exchange modes, depending on your preference and network topology. You can also create connectivity associations to define the MACsec attributes for each link.
3. Monitor: You can use the 21197 Link Secure dashboard to monitor and manage your MACsec-secured links. You can see the status, statistics, and alerts of your links, as well as troubleshoot any issues that may arise. You can also use the 21197 Link Secure API to integrate with your existing systems and applications.
