Description: A security layer in a VPN (Virtual Private Network) refers to a set of measures and protocols designed to protect the integrity, confidentiality, and authenticity of the data transmitted over the network. This additional layer of security is crucial, as VPNs allow users to connect to public networks securely, but they can also be vulnerable to attacks if not properly implemented. The main features of this security layer include data encryption, which converts information into an unreadable format for interceptors; authentication, which verifies the identity of users and devices attempting to access the network; and data integrity, which ensures that information has not been altered during transmission. The relevance of this security layer lies in its ability to protect user privacy, especially in a world where cyber threats are increasingly common. Without a robust security layer, sensitive data such as passwords and financial details could be easily accessible to attackers, highlighting the importance of implementing these measures in any VPN solution.
