Kerberos Registration
Port 760 is utilized by the Kerberos registration service (known as krbupdate or kreg). It facilitates the registration and update of Kerberos principals and credentials, enabling centralized identity management and secure authentication within a networked environment..
Port 760 serves the Kerberos registration daemon (krbupdate/kreg), an auxiliary component of Kerberos environments. This service allows users and administrators to register new principals, modify credentials, or update key tables securely. It bridges the gap between identity provisioning and secure authentication processes that Kerberos is known for.
Typically, the krbupdate service operates over both TCP and UDP, providing flexibility depending on network requirements. TCP ensures reliable delivery of update requests and confirmations, while UDP can reduce latency for simpler or more lightweight transactions. The port is generally open internally within trusted segments of enterprise or academic networks, often during initial setup phases or periodic credential rotations.
Unlike ports 88 or 464, which handle authentication queries or password changes, port 760's role is provisioning credentials. The krbupdate service integrates closely with the Key Distribution Center (KDC) to maintain accurate and secure identity records, publishing new keys without exposing sensitive data to the network unlawfully.
