Was out and about today. Was at a workplace that used fairly standard firewall software by the looks of things.  I got blocked trying to access The Australian IT.   The story in question? Stephen Conroy wades into child porn net flood.

What are the chances that the intended system will perform better than a commercial off the shelf solution?

Well you might assume it wouldn’t be a problem in a filter the Australian Government is dumping a whole heap of money on. Or will it?

Mr Rizvi—At a very broad level, the purpose of the pilot is to look at two streams of potential filtering. The first stream of filtering is in terms of just filtering the ACMA black list and different methodologies for filtering the ACMA black list. What we will seek to test is the impact of that type of filtering in terms of a range of criteria. We will also test more sophisticated types of filtering that go beyond just simply testing the ACMA black list through to filtering larger black lists and also looking at other types of filtering including dynamic filtering, filtering using key words—those sorts of methodologies—to see what the impact of that type of filtering is in terms of both the ISP and the customer.
