Description: Layer 2 security refers to the security measures applied at the data link layer of the OSI model. This layer is fundamental for communication in networks, as it is responsible for the transfer of data between devices on the same local network. Security measures at this layer are crucial for protecting the integrity and confidentiality of the data being transmitted. They include techniques such as device authentication, data encryption, and intrusion detection. Layer 2 security is especially relevant in environments that use technologies like Ethernet and Wi-Fi, where vulnerabilities can be easily exploited if proper measures are not implemented. Additionally, Layer 2 security complements other layers of the OSI model, creating a defense-in-depth approach that helps mitigate risks and protect network infrastructure from malicious attacks.
