• Dude, your firewall is slowing me down (Part I)

    It’s the conversation I've had so many times over the years as both a security professional and as the security architect of financial market trading platforms.

  • My mum always told me to wash my hands

    Growing up, my mum always got me to wash my hands after going to the toilet, or having been outside playing—and of course before I sat down to eat dinner. Why did she do this? In fact why do all good parents do this? Of course, it’s to help minimise the risk of ingesting some ‘bug’ and becoming sick.
