The Department of Defence will take on a managed Internet gateway service to replace its Defence Internet Gateway (DIG).
A new High Availability Internet Gateway Service (HAIGS) that aims to provide up to one gigabit per second of throughput will be developed, Defence documents read.
The HAIGS — described as a “black box” managed gateway service — is expected to offer a “high capacity, secure, robust, and highly available bi-directional connection between the Defence Information Environment (DIE)”, external parties and the Internet for users on the Defence Restricted Network (DRN).
The move to a managed service is expected to free up data centre space and allow the department to share risk while improving visibility of Internet access costs.
The HAIGS system will provide email exchange functionality for communication between Defence and Internet-based accounts, Internet access for those on the DRN, public access to Defence websites, controlled and limited file transfer capabilities, mobile computing capabilities and access to external partners.
The system will consist of four sub-systems: Gateway subsystem; Internet service subsystem; communications subsystem; and a management subsystem.
To ensure security requirements are met the HAIGS will also be monitored by the Australian Defence Force Computer Security Incident Response Team via several network taps. In February, Defence continued to overhaul its ICT systems under the Defence Strategic Reform Program, with the announcement that it will implement a Garrison and Estate Management System (GEMS) by December 2012.
GEMS, an expansion of the current Defence SAP Systems ROMAN and BORIS, has been identified as critical to the building maintenance and garrison services elements of the Non-Equipment Procurement stream of the Defence Strategic Reform Program.
