DATA SECURITY AND HARDWARE
Confidentiality of data used for linking was maintained in accordance with the High Level Principles for Data Integration using Commonwealth data endorsed by Commonwealth Secretaries in 2010. Operational arrangements for managing data flows within the ABS included restricting access to information through the 'functional separation' of roles. These roles ensured segregated access to data and separated those requiring identifiable information for linking and clerical review from groups performing data analysis. For more information refer to the separation principle on the National Statistical Service website (www.nss.gov.au).
All data preparation, linking and clerical review was performed using password-protected remote virtual servers located within the Census Data Processing Centre (DPC) environment. These servers were designed to cater for the memory-intensive requirements of FeBRL, with each server consisting of eight processors with 72 GB RAM, 800 GB hard disk, and running a Windows 7 operating system.
