15.12.2021 · What is Kerberos? And How Does it Work? Kerberos is a computer network security protocol that authenticates service requests between two or more trusted hosts across an untrusted network, like the internet. It uses secret-key cryptography and a trusted third party for authenticating client-server applications and verifying users' identities.

Kerberos builds on symmetric-key cryptography and requires a trusted third party, and optionally may use public-key cryptography during certain phases of ...

Kerberos protocol messages are protected against eavesdropping and replay attacks. Kerberos builds on symmetric-key cryptography and requires a trusted third party, and optionally may use public-key cryptography during certain phases of authentication. Kerberos uses UDP port 88 by default.

TCP, UDP port 88: Kerberos; TCP port 445 : SMB; Active Directory Authentication Ports. Active Directory uses the below port for active directory authentication. UDP port 389 : LDAP; TCP port 53 : DNS; TCP, UDP port 88 : Kerberos; TCP, UDP port 445 : SMB over IP; Using Active Directory Ports. Active directory ports help you to understand which ports to allow in the firewall.

Ports 88 and 464 are the standard ports for Kerberos authentication. These ports are configurable. Port 464 is only required for password change operations.

Strictly speaking, the only port that needs to be open for Kerberos to function properly is 88. The other ports can be opened as needed to provide their respective services to clients outside of the firewall. Because of the inherent flaws in the Kerberos 4 protocol, it is not recommended that you open Kerberos 4 to the Internet.

This may require special configuration on firewalls to allow the UDP response from the Kerberos server (KDC). Kerberos clients need to send UDP and TCP packets on port 88 and receive replies from the Kerberos servers.
