Description: Link Layer Security refers to the measures implemented at the second layer of the OSI model, which is responsible for data transmission between devices on a network. This layer is crucial for ensuring that data is transmitted securely and without interference. In the context of modern networks, link layer security becomes even more relevant due to the increasing number of connected devices and the need to protect sensitive information being transmitted. Security techniques at this layer include device authentication, data encryption, and information integrity. These measures help prevent attacks such as sniffing, where an attacker intercepts data in transit, and spoofing, where a malicious device impersonates a legitimate one. Implementing robust security protocols at the link layer is essential for maintaining data confidentiality and integrity, as well as ensuring trust in communications within the network. In summary, link layer security is a fundamental component of network architecture, ensuring that data transmission is secure and reliable.
