Transparency of Security Efforts in ICANN: Update
Today, the ICANN organization published our Cybersecurity Transparency Guidelines [PDF, 17 KB], which reaffirm our commitment to a high standard of openness and transparency concerning the security of the systems and services we operate.
Late last year, we identified the need to fill a gap in how we ensure that the ICANN org’s internal guidelines and processes meet the community’s expectations for transparency around information technology (IT) security.
In general, we will disclose major security vulnerabilities and resulting incidents that cause significant risk to the security of ICANN’s systems, or to the rights and interests of data subjects, or otherwise require disclosure under applicable legal requirements, in a cybersecurity incident log. The log will include incidents, the ICANN org’s response, and impact.
Obviously, security incidents deserve appropriate and thorough investigation. In the context of our desire to notify our community, our initial goal is to deliver these notifications within 60 days after we become aware of an incident, with an eventual target of 30 days.
If you have any questions or feedback, please email me directly at firstname.lastname@example.org.
Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as""icann.org"" is not an IDN."
