Annual IANA Functions Audits Validate ICANN Systems Controls

LOS ANGELES – 29 March 2018 – The Internet Corporation for Assigned Names and Numbers (ICANN) has completed audits of the Public Technical Identifiers (PTI) Registry Assignment and Maintenance Systems (RAMS) and the Root Zone Domain Name System Security Extensions (DNSSEC) services provided as part of the IANA functions. International accounting firm PricewaterhouseCoopers (PwC) conducted the audits for the period of 1 October 2016 through 30 November 2017.

For the fifth consecutive year, a Service Organization Control (SOC) 2 audit of PTI's RAMS shows that the ICANN organization has the appropriate controls in place to ensure the security, availability, and integrity of IANA request processing.

For the eighth consecutive year, SOC 3 certification has been achieved for the management of the DNSSEC root key signing key, which is the trust anchor of the domain name system. The SOC 3 certification demonstrates that effective security controls are maintained to manage the root key signing key. The certificate is publicly available at: http://iana.org/audits.

SOC audits evaluate an organization's controls in relation to "trust services principles and criteria" and are managed by the American Institute of Certified Public Accountants (AICPA). In August of 2017, the ICANN org solicited proposals for an independent auditor to conduct future SOC audits. After careful consideration, RSM US LLP was selected to conduct these audits beginning 1 October 2017. "PwC has done a great job as our audit firm since 2010, and guided us as we established an audit culture within our organization. Industry best practices suggest periodically rotating auditors to gain a fresh external perspective, and we determined it was the right time to make the switch to ensure ongoing community confidence in our service delivery. We are grateful for the many years of service that PwC has provided and welcome the team from RSM," said Kim Davies, ICANN's Vice President of IANA. Kim Davies also serves as President of the Public Technical Identifiers (PTI), the affiliate of ICANN that provides the IANA functions.

About ICANN

ICANN's mission is to help ensure a stable, secure, and unified global Internet. To reach another person on the Internet, you need to type an address – a name or a number – into your computer or other device. That address must be unique so computers know where to find each other. ICANN helps coordinate and support these unique identifiers across the world. ICANN was formed in 1998 as a not-for-profit public-benefit corporation with a community of participants from all over the world.

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."
