Kerberos
Kerberos is a security system that helps verify the identity of users and computers on a network, similar to how a security guard checks ID badges at an office building. It's widely used in business environments, especially in Windows networks and large organizations. When someone tries to access company resources like email or files, Kerberos acts like a trusted middleman that confirms they are who they say they are, without sending passwords across the network. This makes it harder for unauthorized people to gain access to sensitive information. It's considered an industry standard for network security, particularly in enterprise environments.
