The common implementation of passwords in the domain name industry (both overseas and Australia) is the following: (1) the use of a customer username and password. Typically this gives the customer access to all their domain names, email services, and web hosting services. Melbourne IT calls this a "MyAccount password". (2) a per domain name password. Typically this is used within a registrars system to authenticate moves from one customer account to another, or one reseller account to another. Melbourne IT calls this a "Registry Key", and this is usually not exposed to new customers. (3) an EPP authInfo password (see IETF RFC 3731). Typically this is used within a registry system to authenticate moves from one registrar to another registrar. I recommend that auDA consider renaming "Domain Name Password" to "authInfo password for authorising changes of auDA registrar". ICANN has recently carried out a review of domain name security in the context of the growth of domain name hijacking. From: http://www.icann.org/committees/security/sac007.htm "Registrant identity verification used in a number of registrar business processes is not sufficient to detect and prevent fraud, misrepresentation, and impersonation of registrants. ICANN Policy on Transfer of Registrations between Registrars specifies that "consent from an individual or entity that has an email address matching the Transfer Contact email address" is an acceptable form of identity. Transfer Contact email addresses are often accessible via the Whois service and have been used to impersonate registrants. Publishing registrant email addresses and contact information contributes to domain name hijacking and registrant impersonation. Hijacking incidents described in this report illustrate how attackers target a domain by gathering contact information using Whois services and by registering expired domains used by administrative contacts." I recommend that: (1) Passwords not be sent to publicly available registrant email addresses from a process outside of a registrar (e.g via the registry or auDA websites). Whenever a registrar receives a request to send a password to the default email address, the registrar should also inform the registrant via other contact means (e.g fax, alternative email address, phone call etc) that a request has been received for the password and the password dispatched to the default email address. This ensures that if the email address has been compromised, that a registrant has a chance to be informed that someone is attempting to gain control of their domain. (2) With respect to section 4.3 of the domain name password policy, there has been an increase in "fax" fraud whereby a person falsely signs a document claiming to be the registrant. I agree with Brett Fenton that this should be tightened up, with a requirement that signed written documents be notarized (under Australian law), and originals be provided. Regards, Bruce Tonkin
