GSS-TSIG (Generic Security Service Algorithm for Secret Key Transaction) is used to authenticate DDNS updates. It is a modified form of TSIG authentication that uses the Kerberos v5 authentication system. GSS-TSIG involves a set of client/server negotiations to establish a "security context." Specifies the Generic Security Service Algorithm for Secret Key Transaction Authentication for DNS (GSS-TSIG) Protocol Extension, which identifies one possible extension to TSIG based on the Generic Security Service Application Program Interface (GSS-API).

For this reason, it is not possible to configure a Windows Server running the Microsoft DNS service to perform zone transfers from a server running BIND DNS configured as a master authoritative server with TSIG protection on the allow I know you guys are currently working through the GSS-TSIG portions but I think you're working towards doing the actual update afterwards. Be aware that Windows 2012, both the DNS server and clients, seem to be insanely picky about the compression used in both the TKEY/TSIG exchange as well as actual update. 2019-09-08 · As an aside, the nsupdate module relies on dnspython, which itself doesn't support GSS-TSIG. So it may be a while before the upstream issue is worked out.

Published: 17 February 2021 BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options. Name: CVE-2020-8625: Description: BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features.

It is a modified form of TSIG authentication that uses the Kerberos v5 authentication system. GSS-TSIG involves a set of client/server negotiations to establish a "security context." GSS-TSIG (Generic Security Service Algorithm for Secret Key Transaction) is an extension to the TSIG DNS authentication protocol for secure key exchange. It is a GSS-API algorithm which uses Kerberos for passing security tokens to provide authentication, integrity and confidentiality.

It’s an extension to TSIG, which provides a lightweight protocol for authenticating and protecting the integrity of messages between, say, DNS client and server. Would it be possible to add support for GSS-TSIG (RFC 3645)? This would make it possible to perform secure DNS updates to a Windows Active Directory environment, which AFAICT doesn't support normal TSIG updates.

GSS-TSIG - What does GSS-TSIG stand for? This is most useful for allowing RFC 3645 GSS-TSIG which is necessary for dealing with Windows DNS servers that require 'Secure only' updates or BIND if it has been configured to use Kerberos.

To use the Authoritative Zone editor: From the Data Management tab, select the DNS tab -> Zones tab -> zone check box -> Edit icon. GSS-TSIG uses the GSS-API interface to obtain the secret TSIG key. GSS-TSIG is an extension to the TSIG protocol. See Procedure 33.2, “Sending an nsupdate Request Secured Using GSS-TSIG” GSS-TSIG. GitHub Gist: instantly share code, notes, and snippets. TSIG¶. TSIG, as defined in RFC 2845, is a method for signing DNS messages using shared secrets.Each TSIG shared secret has a name, and PowerDNS can be told to allow zone transfer of a domain if the request is signed with an authorized name.
