I was cleaning out a drawer in my home office this morning and found this collection of old USB memory sticks dating back quite a few years. Remember those days when you thought you were so cool because you had this little storage drive full of all your stuff in your pocket? I recall working in a school back in those days where we actually mandated that every student had to have a "USB"*, such was the apparent importance of these things. The intention was for students to keep their personal data safe and secure, but we used to constantly find them left behind in the USB ports of the classroom computers after a lesson. Or they would sometimes mysteriously just stop working. Or the kids would lose them. USBs may have been cool, portable and handy, but they were about the most insecure method for managing data I can think of. *(Side note: Calling them simply a "USB" seems stupid to me, because USB - or Universal Serial Bus - is a data interface standard, not a name fo...

I read an article today in an educational newsletter about keeping your accounts safe with a strong password.  It suggested a range of sensible things like having at least 8 characters, using a mix of uppercase, lowercase, numbers and special characters, and not reusing old passwords.  All pretty good advice. I hear a lot of people expressing concern about the security of "the cloud".  They worry that their data could be compromised if kept on a server they don't own themselves, or a server that is located somewhere else, possibly even in another country.  They express concerns about data breaches from hackers, security breaches of data centres, or even data being accessed by foreign powers during a government uprising. Is any of this possible?  I suppose so. Anything is possible. Unlikely perhaps, but possible. If it's true that anything is possible, and we want our data to have zero risk, then we need to not keep data anywhere. The only sure way to have no ris...

I had a knock on our front door a few weeks ago. It was a young English guy going door to door for an electricity retailer, trying to get me to switch my power company.  As it turns out, it was his first day so he didn't really know a lot about what he was selling and couldn't answer many of my questions in detail. To be fair, I can be a bit analytical about these things and I don't think he was prepared for so many questions. His spiel was basically "You should switch to us because we are better", but when I asked about the rates they charge, all he could respond with was "We have really good rates". If you ever come knocking on my door, whether you're trying to get me to switch energy companies, make a donation to your cause, or convince me that Jesus loves me, you better be prepared to engage. I ask lots of questions. You better have answers. So I grabbed my most recent power bill, and asked him exactly what their rates were per KWh. He had never ...

I received an email recently from a colleague asking about data sovereignty, and in particular asking about how schools deal with the  need to store all personal data on Australian servers to be compliant with the law. This was my reply... When deciding whether to do a thing - any thing - you need to assess the relative risk. There is NOTHING that can have it's risk mitigated to zero. So while we can have debates about the security of the cloud, the fact is that ANY service is generally only as safe as the password that protects it. It's far simpler to socially engineer your way into a system than to hack it, and it's easier to follow someone through an open doorway before the door shuts than to crack the lock. There are security risks involved with every system. What makes you think that data saved on a server that happens to be geographically located on Australian soil is any safer than data on a server located on the other side of some imaginary geographical dividing l...

I've been travelling a fair bit lately .  Although much of it has been within Australia, I've just spent the last few days in Lower Hutt, New Zealand, for the Sitech Champion Schools Conference , and I'm writing this from in the hotel foyer. New Zealand is starting to feel a bit like a second home lately... this is my fourth trip here in the past 12 months. Aussies and Kiwis have a friendly relationship. Aside from the obvious opportunity to take shots at each other over the cricket and the rugby, our two countries get along amicably well, and the trip across the Tasman is something that feels more like going interstate than international.  It's easy to feel at home in NZ. About 12 months ago I was here for last years Champion Schools Conference and some readers of this blog may remember that I came home to a $1000 phone bill for international roaming. That was a saga in itself , and much was said about it both here on the blog and on Twitter and Facebook.  While I sho...

It's sometimes difficult getting kids to understand the full implications of something as seemingly harmless as putting their photo online. They often don't realise that, just like The 500 Hats of Bartholomew Cubbins , once something goes online it is near impossible to remove it. This video makes a pretty good point of showing the effect of this behaviour... [kml_flashembed movie="http://www.youtube.com/v/iwBz-hxjSLU" width="425" height="350" wmode="transparent" /] It's something that both children and adults need to understand well. This is a post-Google world we live in. It's no longer unusual that an employer Googles the name of a potential hire to check their reputation and see what they have done (or equally, not done). When you go out with a new person, it's likely that your date has Googled you, MySpaced you or FaceBooked you to get a little bit of "background" on the sort of person you are. In a digita...
