  • Australia vs insecure IoT devices

    Heh good luck with that…..

    Australia seems to be interested in taking a stand against insecure IoT devices.

    http://www.smh.com.au/federal-politics/political-news/webconnected-household-devices-to-face-mandatory-rating-over-spying-fears-20171013-gz08jp.html

    Internet-connected products from baby monitors to sports shoes will soon bear a mandatory Australian cyber security consumer rating amid growing alarm at hacking of everyday devices.

    The Turnbull government is pushing the technology industry to come up with its own consumer advice rating that could be a “cyber kangaroo” logo giving a tick of approval or a star system similar to the health stars on some packaged food, and energy stars on electrical appliances.

    I mean yeah, good on ya mate and all, but that horse is so far gone, you ain’t ever going to get any sort of control (security) over these sorts of devices any time soon.
    Now, should we just give up then, and let anything come into the country?
    Well, no, but nothing about their approach thus far has left me with any confidence that they can manage this intelligently. (For example, they want encryption, but not for the bad guys).

    He said he recently began talks with the US and Britain about harmonising the three countries’ approach to the problem in order to set an example to the rest of the world.

    Mr Tehan said any regime in Australia would ultimately need to cover imported products as well as those made here. Most basic household web-enabled devices were made in Asia, he said.

    “What we want industry to do is come up with standards that they think are minimum requirements for IoT devices.

    “And that ultimately we want to apply to imported products as well.

    “If you’re a reputable manufacturer of baby monitors, if it becomes public that your devices aren’t cyber secure, my view is that’s going to hurt your reputation. That is what we are hoping will drive the change.”

    Here is a bit of the problem, they are talking about three very different countries, USA, UK and Aus. Yeah. Good luck getting those three to agree.

    But, the last sentence is where it really unravels…. They say that simply shaming the company is going to cause a change. No. It won’t.
    I really don’t think that this is enough to drive the change.

    So, yeah, good to have the conversation, and start the ball moving, but I sort of feel sorry for my geek brothers down under, buying the cool hardware is going to get even harder and more expensive than it already is.


  • Seismic waves visualized.

    Great (except for the ‘music’, so be sure to mute it) video showing the different waves you see around any given earthquake.
    It illustrates beautifully why it’s not always ‘clear’ just what waves you are seeing after a biggish quake from just one station.
    This is why I am glad to be part of the bigger network of seismographs.
    My data can contribute to the greater bucket of data and thus be part of reducing the noise and extracting the signal.


  • Back but busy

    We are back from our 8 day church retreat. It was a good time away, Freddy and I managed to ballance it with social time, quiet time and together time. All in all, very profitable for the mind, body and spirit.

    We are still busy at work with the Inductive Automation Exam. Going to be at it for a few more weeks. The stress of getting it done is overflowing into home life, so we have not been, nor will we, be blogging much till we get it out of the way I suspect.
    I want to tinker with a few things, but lack the energy and mental focus till we are done with it.

    For personal reasons our year starts and ends at different times, so for the most part, we are looking into a new year from here.
    Goals for the coming year.
    I want to get two robots sorted this year, it’s been too long for them sitting in the garage. More will be said when we get to them.
    I have a double deck fridge in the lounge room that Freddy and I want to get running under Opto control, the idea is to see if the smaller (but dual temperature range) fridge can take the contents of the wine fridge in the garage, then we can sell that one and make some more storage space.
    Want to get the solar batteries and inverter moved from the back patio to the Drone Room and running the computer gear.
    Lastly, I want to get the doors sorted out on the Smart Car (aka, make them lighter).

    In among all this we hope to plan a road trip to Canada.

    So that’s the plans for this year. I’m sure, without a doubt, that there will be many things that will spoil these plans, hopes and dreams, but eh, gotta start somewhere.


  • Inductive Automation

    One of the things that has kept me REALLY busy at work for the past…oh… 5ish weeks is getting up to speed on Inductive Automation’s software package called Ignition.

    I don’t want to get too hung up on exactly what it all is and why we (Opto) are doing it, but enough to say that it is a suite of software that allows communication with different hardware controllers (like Optos) and it itself has scripting built in (Python), so can do some control and it also has a slew of visual designer software (like groov), alarming, logging, historical and database options.

    The learning process is what is keeping me busy.
    They have this amazing on-line training program.
    Each section is broken down into videos, at the end of the section there is an ‘exam’ or test.
    Since my end goal is to become certified in the software, I must get 100% on each sections exam. At the end of all the sections, Opto sends my 100% result in and they then send me the written exam. Once I do that, we send it back, they grade it, and if I pass, I am certified in their software and we are done. If I fail, I have to retest (since the end goal really is to become certified).

    There are 22 courses, you can see them here. https://inductiveuniversity.com/courses/all
    Lets take a look at one at random and see what its like….
    https://inductiveuniversity.com/video/about-transaction-groups?r=/course/transaction-groups
    Go ahead and click play. You don’t have to watch the whole thing, just a get a taste.
    The guys do an amazing job of breaking down what each function does and how the software glues it all together.
    At the bottom of the video list on the lower right is the exam link.
    The exam is multi choice…. Here is where I have a few comments…..
    I have never been through a process like it…. Benson said it is ‘critical thinking’ testing.
    For example…. They will ask if something can not be done in the software, true or false.
    This really makes me have to think. True it cant be done, or false, it can be done. The double negative really throws me.
    The other question style is each answer is an un-ordered list, so you have to work each answer into the right order, if you even can, and then figure out if it is the right answer for the question.
    The other ‘tricky’ thing they do is ask if you can do a function in the software… and you are sitting there going ‘wait.. I watched the video, but I don’t remember them mentioning that….??’ I tended to doubt myself a few times, so you go back and re-watch the video only to come away sure that they did not mention it and so the answer is no, you cant do it… So yeah, they test you on what they did not show you. Phew.

    So, yeah, now you know what has been keeping me super busy at work.
    I got the written exam this morning, and its pretty intense.
    Will let you all know when we get the results. I’m confident I can pass, just need to take my time and be sure I answer it correctly.


  • Seismograph – Part 5

    No more tweaks to the vault, so this is about how things are just working really well.

    Sadly, due to a software bug, I lost the actual page of the big quake off the coast of Mexico, so here is the photo I happen to take of the screen that morning.

    Just a massive quake that ran for many minutes and then picked up a bit half hour or so latter.

    Now, as for all these, I truly am sorry to say that I have been super distracted (massive (or not) blog post coming – relax, it’s really geeky techo stuff) and so I just have not been keeping up on exactly which quakes all these traces are from.
    I guess my point in showing them all is that the system is working really well.
    The last point I want to make is that RaspberryShake guys are working on a system that sends an email as soon as a big quake is detected on each of our seismographs, so I will be able to keep track of them much better.

    You can click on each image, then your browser should let you click again and you can pan around, so you can see the dates and could go back through the USGS website and link all these up.
    Impressive that 2 of the pages have 2 quakes on them.
    The new vault seems to be working well?

    Till then, here are some amazing traces from my station in Temecula.
