Description: Link Layer Security (LLS) is a security protocol that provides confidentiality and data integrity at the link layer. This protocol operates at the second level of the OSI model, meaning it acts on communication between devices in a local network. LLS is responsible for protecting the data transmitted over physical connections, ensuring that information is not intercepted or altered during transit. Key features include the use of encryption techniques to ensure confidentiality and the implementation of authentication mechanisms that verify the identity of the devices involved in communication. The relevance of LLS lies in its ability to mitigate risks associated with ‘man-in-the-middle’ attacks and other threats that can compromise information security in local networks. In an increasingly interconnected world, where data security is paramount, LLS becomes an essential tool for protecting the integrity and privacy of information in network environments, especially in critical applications, where data security is a constant concern.
