IoT Device Security Considerations and Security Layers – Power Source

Architecture, IoT, Security

ThingsFollowing on from my post on IoT Device Security Considerations and Security Layers the subject of this blog post is to look at the Power Source layer.

Power Sources for IoT Devices will differ depending upon the type of IoT Device being used or designed and its use, however they will fall into 3 main source of power.

  • Mains
  • Battery
  • Wireless

So how secure is a power source? There have been demonstrations on how data can be hacked through power outlets (How to use electrical outlets and cheap lasers to steal data) which have concentrated on using the fluctuations and noise in the power supply to work out what is being typed. This would effect both mains and wireless connections as these could be monitored in some way.  Battery presents a more secure method of providing a power supply.

At present any breaches using a power source are few and far between, however as the IoT connected world continues to evolve, perhaps this is one area that more security considerations are needed.

Not all IoT Devices will need mains power as there is a huge drive for wearables and mobile. The mains power would be aimed more at IoT devices within a business (such as plant machinery sensors) or a home system (turning on power or heating).

Mains also provides a medium to connect IoT devices such as Smart Meters or a Home Network over the mains using Ethernet to Power converters. IoT devices may well utilise this as a method to communicate back to a local hub, then off to a central hub via normal network connectivity.

There are already standards/rules for smart meters set out to protect devices and consumers around:

  • Data Access and Privacy
  • Security

(Smart meters and how they work)

Battery IoT Devices tend to be self contained for power and apart from a future change of the battery when its power expires connectivity and networking tend to be through the front end.

As the IoT advances there will be advancements in the protection for devices and in the rules that govern them. Not all devices will be equal with the same power needs, but one thing is constant. They all need power to operate in one form or another.

Habits and Patterns

Architecture, Tools

During my recent vacation I was staying along the “Dinosaur Coast” in the UK and took my son fossil hunting along the coastline.  Along the way were several other fossil hunters ranging from Amateurs to Semi Professionals.fossil

The thing I noticed observing the other hunters was their habits and methods used in searching the rock faces and surrounding areas in finding fossils.

These ranged from random searches and tapping on rocks with a hammer to careful methodical searching and testing of the rock.

Much in the same was I have observed in my time as an Architect and in business of peoples habits and patterns, however it was more noticeable as I was not in my normal bubble of work/life.

We tend to apply a pattern based on our own skills, knowledge and behaviours that we are comfortable with. Perhaps we should challenge our own habits and look at where efficiencies and benefits can be brought in.

A habit (or wont) is a routine of behaviour that is repeated regularly and tends to occur unconsciously.

– Wikidpedia

A good reference on habit is “The Power of Habit” by Charles Duhigg. Duhigg explains why habits exist and how they can be changed.

With patterns we can create, change or learn based on our needs. Patterns provide that repeatability that is needed for some tasks and solutions.

A pattern, apart from the term’s use to mean “Template”, is a discernible regularity in the world or in a manmade design. As such, the elements of a pattern repeat in a predictable manner.

– Wikipedia

A good reference for patterns is by Christopher Alexander

Each Patterns describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice.

– Christopher Alexander

Alexander defines a ‘pattern’ as a three part construct.

  • First comes the ‘context’; under what conditions does this pattern hold
  • Second is a ‘system of forces’. In many ways it is natural to think of this as the ‘problem’ or ‘goal’.
  • Third is the ‘solution’; a configuration that balances the system of forces or solves the problems presented.

By observing the other fossil hunters and their habits and patterns, we successfully found a couple of good Annomite and Belemnite fossils by Learning from others.

My lesson learnt on this vacation is to “Challenge the habits and create/follow a pattern where possible”.

Architecture, Development, Innovation, IoT

A recent paper from the Cornell University has been published that covers a “Survey of Operating Systems for the IoT Environment“. (IoT = Internet of Things). Things

It looks at the Operating Systems produced for the chipsets used in IoT sensors, RFID and devices.

The paper lists the following Operating Systems and provides an overview of their capabilities and aligned chipsets.

  • mbed (ARM)
  • RIOT OS
  • Contiki
  • TinyOS
  • Nano-RK
  • FreeRTOS

The paper is worth a read if you want a good overview of IoT Operating Systems and their capabilities.

Race to the largest Raspberry Pi Cluster

16 Monday Mar 2015

Architecture, Cloud, IoT, Programming

The humble Raspberry Pi has been around for some time and its popularity is growing again with the latest release of the Pi and is a great development platform for the Internet of Things both cost wise and its sheer versatility from basic programming and running Minecraft, to hosting a Docker server.

GCHQ have recently announced the clustering of a 66 node Pi cluster called bramble. They have just pipped the University of Southampton who built a 64 node Pi cluster out of the Pi and Lego.

Some other earlier attempts have seen a 32 Node Cluster Beowulf from the Boise State University.

However it would appear that a 120 node Cluster is currently being developed.

With the 32 node cluster costing roughly the same as a PC, this technology has certainly brought high powered computing into the reach of most people today and the applications going forward are huge for development of solutions.

Architecture, Enterprise Architecture

BooksThere are many good examples of Enterprise Architecture documentation available as reference on the Internet. All following different methodologies, but ultimately illustrating how an Enterprise Architecture documentation set can assist in driving strategy and the business forward.

A bit dated now (2004), but a good example of such a document set is the 5 volumes from NASA.

NASA Enterprise Architecture Vol 1 – NASA Enterprise Architecture

NASA Enterprise Architecture Vol 2 – Office Automation, IT Infrastructure, and Telecommunications

NASA Enterprise Architecture Vol 3 – Program Unique IT and Multi-Program / Project IT Investment Category

NASA Enterprise Architecture Vol 4 – Strategies and Structure

NASA Enterprise Architecture Vol 5 NASA To-Be Architecture, Approach to Design and Implementation

The documents are based on the Federal Enterprise Architecture Framework

Enterprise Architecture – Wikipedia Book

Architecture

A while ago I created a book on Wikipedia on Enterprise Architecture (Back in August 2009) using Wikipedia Books. This is a function to pull together articles from Wikipedia together in a book format, then download as a PDF or even send to get printed.

I haven’t got far with the printing aspect on this book, although I did pull together some articles on a different subject and sent that to be printed. I was happy with the bound book that came back from the service and it was a reasonable cost.

Thought I would go back and revisit the book and see where it is up to today.

Available at https://en.wikipedia.org/wiki/Book:Enterprise_Architecture

I have created this as an open book so it can be added to should anyone wish to assist in collating relevant articles.

The current index is made up of following articles:

Enterprise Architecture

Enterprise Architecture Assessment Framework
