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. [2] Kerberos uses UDP port 88 by default.
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
Kerberos is a centralized network authentication system developed at MIT and available as a free implementation from MIT but also in many commercial products. It is the default authentication method in Windows 2000 and later.
In computer networking, the User Datagram Protocol (UDP) is one of the core communication protocols of the Internet protocol suite used to send messages (transported as datagrams in packets) to other hosts on an Internet Protocol (IP) network. Within an IP network, UDP does not require prior communication to set up communication channels or ...
In a Windows network, NT (New Technology) LAN Manager (NTLM) is a suite of Microsoft security protocols intended to provide authentication, integrity, and confidentiality to users. [ 1 ] [ 2 ] [ 3 ] NTLM is the successor to the authentication protocol in Microsoft LAN Manager (LANMAN), an older Microsoft product.
Integrated Windows Authentication (IWA) [1] is a term associated with Microsoft products that refers to the SPNEGO, Kerberos, and NTLMSSP authentication protocols with respect to SSPI functionality introduced with Microsoft Windows 2000 and included with later Windows NT-based operating systems.
The client would encrypt the ticket (password) with the public key and send the result back to the server, which would decrypt and verify the ticket. The current SPICE protocol also allows for use of the SASL authentication protocol, thus enabling support for a wide range of admin configurable authentication mechanisms, in particular Kerberos.
