Having been on a customer site all day, I returned home to scan my email.
Over half the emails were festive greetings, with all sorts of creative content: embedded images, attached animated images, links to sites with festive messages and attached files with seasonal offers.
What could possibly go wrong? Continue reading
The Culture, Media and Sport Committee, appointed by the House of Commons, has produced a report on “Cyber Security: Protection of Personal Data Online”
Recommendation 3 states “To ensure this issue [cyber security] receives sufficient CEO attention before a crisis strikes, a portion of CEO compensation should be linked to effective cyber security”

Dear Virgin Media
I recently decided it was time to change my password on my NTLWorld email account (managed by Virgin Media). I entered a new password only to be told “Password too long”. How long was my password? 11 characters. 10 characters are OK apparently. Continue reading

A recent project at Nexor required us to look at the challenges of providing access to the DNS from a secure environment. It reminded me of the issues related to DNS tunnelling.
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“.
