Final answer:
Kerberos tickets are stored in a ticket cache on the local system, with locations varying based on the operating system; in Windows within the system memory, and in Unix-based systems usually under /tmp or as specified by the KRB5CCNAME variable.
Step-by-step explanation:
Kerberos tickets are utilized for network authentication protocols within a client-server model. When a user or system needs to prove its identity to another system, it employs a Kerberos ticket obtained from a Key Distribution Center (KDC). On a local system, typically these tickets are stored in a temporary cache associated with the session of the user. In Windows, it is stored in the system memory and can be accessed using the Kerberos Tray application or command-line tools like klist. While in Unix-based systems, Kerberos tickets are typically saved in a file within the user's directory, commonly referred to as a ticket cache with the default location being /tmp or as defined by the KRB5CCNAME environment variable.
