Description: Local Area Network (LAN) authentication refers to the methods and protocols used to verify the identity of users and devices attempting to access a local network. This process is fundamental to ensuring network security, as it controls who can connect and what resources they can use. Authentication can be carried out through various techniques, including passwords, smart cards, biometrics, and, in the case of multifactor authentication, the combination of two or more verification methods. Multifactor authentication is especially relevant in environments where security is critical, as it adds an extra layer of protection by requiring users to provide multiple forms of identification before gaining access. This can include something the user knows (like a password), something the user has (like a token or access card), and something the user is (like a fingerprint or facial recognition). Implementing these authentication methods in a LAN not only helps prevent unauthorized access but also protects the integrity and confidentiality of the data circulating within the network.
