You can protect your network with the Kerberos service. This client-server architecture provides secure transactions over networks. The service offers strong user authentication, as well as integrity and privacy. Using the Kerberos service, you can log in to other systems, execute commands, exchange data, and transfer files securely. Additionally, the service enables administrators to restrict access to services and systems. As a Kerberos user, you can regulate other people's access to your account.
