DNSSEC Key Signing Key Rollover Postponed

Last Revised

The Internet Corporation for Assigned Names and Numbers (ICANN) has announced that the change to the Root Zone Key Signing Key (KSK) scheduled for October 11, 2017, has been postponed. A new date for the Key Roll has not yet been determined.

DNSSEC is a set of DNS protocol extensions used to digitally sign DNS information, which is an important part of preventing domain name hijacking. Updating the DNSSEC KSK is a crucial security step, similar to updating a PKI Root Certificate. Maintaining an up-to-date Root KSK as a trust anchor is essential to ensuring DNSSEC-validating DNS resolvers continue to function after the rollover. While DNSSEC validation is mandatory for federal agencies, it is not required of the private sector. Systems of organizations that do not use DNSSEC validation will be unaffected by the rollover.

Users and administrators are encouraged to review ICAAN announcement KSK Rollover Postponed and the US-CERT Current Activity on DNSSEC Key Signing Key Rollover for more information.

US-CERT will provide additional information as it becomes available.
