First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
AusCERT: Entrusting end-users with security an outdated '70s idea, says author

Ivan Krstic, co-author of the bestselling The Official Ubuntu Book, delivered a scathing keynote at AusCERT 2007 today claiming the tech industry has failed to address securing IT and that far too much still rests in the hands of un-informed end-users.
Delivering the opening address at Australia's premier IT security conference, Krstic said immediate action is required.
"We can fix it now or face another 10 years of empty vendor promises and lousy security products," he said.
"We need to work less on sexy problems and focus on the hard ones that need to be solved."
Today's problems cannot be fixed, according to Krstic, with a 1970s security model.
"Everything you know about desktop security is wrong. Desktop security is about the user not protocols and algorithms," he said, adding that 75 percent of machines are infected with malware.
"Today, there are more than 100,000 known viruses, not to mention spam and phishing and that is because we rely on users to make choices about things they don't understand."
To reinforce his point, Krstic showed how a user interprets a pop-up dialogue box that appears on their screen.
To a user it simply says: "Blah blah, technical terms, I don't understand, blah blah."
Then it will ask the user to press 'yes', 'allow' or 'permit'.
"Of course they will click on 'yes', 'allow' or 'permit' because it rewards them by letting them get back to work. We are training users to ignore security and rewarding them for it," Krstic explained.
"By leaving decisions to uninformed users it means IT security is an unbelievable mess and disaster. How did we get here?"
Krstic said the assumption that every program runs with the permission of the user is a 35 year-old concept.
He said 35 years is equivalent to centuries in IT, adding that "we wouldn't go to war with sticks and stones."
"We run untrusted code every time we open a Web page. It is bizarre," he added.
Krstic went on to criticize the methods used to address these problems.
"Maintaining blacklists is one of the dumbest ideas in computer security; what's the point in keeping an up-to-date list of all the bad things, simply cataloguing badness. That's a losing battle we cannot win," he said.
More than 1100 delegates are in attendance at AusCERT 2007 which is being held on the Gold Coast from May 21-25.
