Dominic White is chief technology officer at SensePost and one of the top experts on information security in South Africa. In this podcast, White talks in detail about how people should secure themselves online - what they need to do to ensure they don't become a victim. It's a wide-ranging discussion that answers questions such as:

* Which is really more secure, Android or iOS?

* Are password managers a good idea?

* Is it safe to connect to public Wi-Fi - and, if not, what should you do about it?

* Should you be worried about government snooping?
