Can you trust your handset?

For many years the Jericho forum has been talking about de-perimeterisation. The basic premise being that as more services become cloud oriented and are accessed with BYOD technology, large elements of the corporate data set are now stored outside of the corporate perimeter.

In looking at the security of such a system, a fundamental question arises. Can you trust the end user devices themselves?

The article “In 2015, security will start with the handset” looks at some of the progress needed in making the handset trustworthy. But this seems a very different position to most organisations looking at BYOD, where the basic premise is (or should be) the BYOD devices cannot be trusted, so you need to control the information flow to them.

I’d argue, today, there is not a right answer – you need to assess the risks in the specific context of a specific situation.

A managed end-user device, in a controlled environment where all the updates have been applied, where an anti-malware solution operates, with at-rest data encryption could offer a perfectly suitable solution to access corporate data from a set of known applications.

On the other hand, a 3 year old Android device, that has never been patched and been used to browse the Internet may not be a great choice for viewing secret data.

It all depends on understanding the risk. To understand the risk, requires understanding the specifics of the user handset. The document set “End User Devices Security and Configuration Guidance” is a really good starting point.

Can we help you with understanding the security risks of your device? An example of how we helped a customer with booting their device securely can be found in the Blog “Booting Linux Securely“.

What Google IoT OS means for your privacy?

Here at CyberMatters we don’t reblog very often.
However here is a good and concise article on some of the privacy challenges the IoT brings, over and above traditional security issues. While this focuses on Google, the challenge is more general.

The new EU data protection proposals will make designing IoT solutions like this that are compliant, a real challenge.

If looking at deploying corporate IoT applications you’ll have to consider privacy issues as well as security. Fortunately help is at hand via our sponsor – Qonex.

An introduction to Information Exchange Gateways

Today marks the beginning of an exciting week for me. I am on site at one of our major clients installing an Information Exchange Gateway demonstrator that I’ve been working on for the last few months. Over that time I’ve seen a growing amount of interest in Information Exchange Gateways (IEGs) from various military organisations, so I decided that it was the right time to start a mini series of blog articles on the topic.

Cyber Threat Glossary – By Example

As more and more people talk about security, I hear the terms threat, vulnerability, mitigation and risk used. Often in what I believe is the wrong context.

There are lots of attempts to define the terms, write taxonomies etc. There is little point in duplicating this, however, here is how I think about the terms…
