Public Comment: ICANN FY 12 Security, Stability & Resiliency Framework

Updated 12 May 2011

ICANN has previously published two Security, Stability and Resiliency (SSR) Plans, in 2009 and 2010. ICANN is today releasing the Fiscal Year 2012 version for public comment in 5 UN languages. This represents a new format for the FY 12 SSR Framework, which is being published to provide for community input prior to the ICANN 41 meeting in Singapore and publication of the FY 12 ICANN Operating Plan and Budget.

This Framework is divided into two sections, and is intended to more clearly describe for the community

  • The foundation of ICANN's role in security, stability and resiliency of the Internet's unique identifiers,
  • Provide an overview of the Internet ecosystem and ICANN's place in it,
  • Describe ICANN's operational priorities in SSR for the coming fiscal year commencing in July 2011, and
  • Distinguish between ICANN's operational priorities, areas in which ICANN is a collaborator and facilitator, and areas in which ICANN is an observer or has awareness on the activities of others in the ecosystem regarding the Internet's unique identifiers

At the informal request of the ccNSO, the comment period is being extended to 7 June 2011 23:59 UTC. Comments on the Framework are welcomed and may be submitted to ssr-fy12@icann.org and viewed at http://forum.icann.org/lists/ssr-fy12/.

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."
