Among other .ZA policies, ZADNA developed and finalised DNSSEC Policy & Practice Statement (DPS).

DPS defines the operational procedures for the management of DNS Security Extensions (DNSSEC) in the South Africa top-level domain (.ZA) and second level domains under .ZA.

It draws on the Internet Engineering Task Force (IETF) I-D for DNSSEC Practices Statement construction, but has a number of significant differences to keep the .ZA DPS appropriate for .ZA.
