9. Technical specifications
9.1. About this section
This section sets out the mandatory and recommended standards required for e-GIF compliance. The abbreviations used in this section are spelt out at the end of the document. There are links in the tables to online resources (usually the standards themselves) that explain more fully what each covers.
9.2. Network
This section covers details of data transport such as network protocols, which is a crucial area for interoperability. Without agreement on networking standards it is hard or impossible to make systems communicate. The e-GIF uses a subset of the widely proven Internet protocol suite.

Authentication (see below) |
9.5.1. Authentication
The EGU Authentication project is working towards an all-of-government authentication solution. The form and implementation of this will be subject to Cabinet decision in 2004. Agencies wishing to implement any new systems where authentication of individuals or businesses is necessary must contact the EGU for advice.
9.6. Security
Security is shown as crossing all layers to reflect the fact it needs to be designed in to a system, not added as a layer on top. The e-GIF contains standards at the various levels designed to offer different levels of security as appropriate. It also refers to a series of standards and policy statements (the NZSITs) which provide advice and direction on the levels of required.

A web based repository for metadata, used to drive the Portal. |
|

Portal News Feed |
News Syndication |
Uses NZ Government RSS to accept news items from government agencies for display on the Portal. This can also provide a feed of government news for use on agency web sites. |
|
Authentication |
Government to Individual and Government to Business online authentication |
This project is still at the design stage and will be implemented only if Cabinet so decides. If so it will consist of standards, procedures and possibly infrastructure. Agencies designing a system with authentication must contact EGU. |
