Some of the iPhone's innovations have made users less secure.
Many Australians are unaware of current police and intelligence powers when it comes to accessing our data.
As companies make quantum computers available through their cloud services, take a look at what it means for computing to move beyond classical mechanics and into quantum physics.
Quantum computing is being described as "just around the corner". Is it?
Governments' efforts to weaken communications security undermine and distract from the need to protect the real weak points in our online communications.
Most people have never heard of the software that makes up the machinery of the internet
- especially the tools that keep us safe.
The Australian government's proposed law that would force technology companies to decrypt messages could make Australians more vulnerable.
