Mandatory data retention laws passed the senate this week. The premise is to fight against Islamic terrorist attacks by retention of ISP customer data. But this will not work out right from the start. ISP`s are confused by the 400 page document that outlines what they must retain, and they are not ready to capture customer data and implement the infrastructure required. Malcom Turnbull has outlined changes in laws. But this is easily circumvented by the use of a Virtual Private Network or VPN. This allows an encrypted connection over port 1701 and hides the data transferred from the ISP. They will just see data over HTTPS. If you configure the VPN to use port 443, this will appear as HTTPS web data and will look rather innocuous. That is how I would configure such a VPN. If you are in an educational institution such as TAFE or school, the detportal proxy will block the standard VPN ports and using port 443 will be required. But this does work very well if you are studying Information Technology and accessing websites such as openvpn.net that is blocked by a proxy. If your home PC is on the same VPN as a machine at your site, you can configure the VPN to allow you to ping the other PC. That is the meaning of a Virtual Private Network. https://www.getup.org.au/campaigns/digital-freedom-and-privacy/go-dark-against-data-retention/go-dark-against-data-retention.
