Winnie the Poo and the Woozles

On Thursday, I joined Sky News, a laptop and an empty Pringles can on a tour of the city's 'Square Mile'. The mission, to eavesdrop on wireless networks and identify those which had failed to put in place even the most rudimentary protection against any passer-by 'dropping-in' to the network.

This stuff isn't new. I wrote about it in The Observer, well over a year ago and just about every computer publication has warned against 'the flakiness' of the wireless world, wide open as it is to hacker-friendly products such as AirSnort.

Wireless LAN (802.11) technology is increasingly attractive to business. I even have a Cisco Aeronet at home. It's wonderful, no cables and I can browse the web and collect my mail from anywhere in the house or garden. Trouble is, you might ask, have I protected myself by enabling the security? Probably not, I am after all at home and surely, wireless stays within the boundaries of my property? Of course it doesn't you'll tell me and the same applies to the fifty or so Wireless LANS that were picked up during the filming of the Sky News piece. Over sixty per cent of the networks detected were completely unprotected, not using WEP encryption (Wired Equivalent Protocol, not using anything, simply wide open, in principle allowing anyone to piggy-back the network for a free ride or worse, collect the traffic flowing back and forth along the network without anyone being the wiser.

It strikes me from looking at the statistics from today's small trawling exercise that far too many network administrators are taking stupid pills. After all that's happened in the last twelve month and the increasingly pervasive atmosphere of security that surrounds us, why on earth aren't they taking the simplest steps to protect their businesses. I don't know but I vaguely remember telling my small daughter a bedtime story, probably Winnie the Poo, which featured an 'Idiot Trap'. "What's an idiot trap" she asked. "Something to do with rabbit, a Pringles can and wireless networks", should have been my reply.

Oh.. And by the way, Woozles, are a type of weasle found in "Wind in the Willows" and only "Heffalumps" fall into idiot traps or so my readers remind me. Just as importantly, an empty Pringles can acts as a natural collector of wireless LAN signals and I'm told that Cheese and onion flavour works best!

The Mandate of Heaven

eGov Monitor Version

“Parliament”, said my distinguished friend “has always leaked like a sieve”.

I’m researching the thorny issue of ‘Confidence in Public Sector Computing’ and we were discussing the dangers presented by the Internet. In his opinion, information security is an oxymoron, which has no place being discussed in a Parliament built upon the uninterrupted flow of information of every kind, from the politically sensitive to the most salacious and mundane.

With the threat of war hanging over us, I asked if MPs should be more aware of the risks that surround this new communications medium? More importantly, shouldn’t the same policies and precautions that any business might use to protect itself and its staff, be available to MPs?

What concerns me is that my well-respected friend mostly considers security in terms of guns, gates and guards. He now uses the Internet almost as much as he uses the telephone and the Fax machine and yet the growing collective t…

Mainframe to Mobile

Not one of us has a clue what the world will look like in five years’ time, yet we are all preparing for that future – As  computing power has become embedded in everything from our cars and our telephones to our financial markets, technological complexity has eclipsed our ability to comprehend it’s bigger picture impact on the shape of tomorrow.

Our intuition has been formed by a set of experiences and ideas about how things worked during a time when changes were incremental and somewhat predictable. In March 1953. there were only 53 kilobytes of high-speed RAM on the entire planet.

Today, more than 80 per cent of the value of FTSE 500* firms is ‘now dark matter’: the intangible secret recipe of success; the physical stuff companies own and their wages bill accounts for less than 20 per cent: a reversal of the pattern that once prevailed in the 1970s. Very soon, Everything at scale in this world will be managed by algorithms and data and there’s a need for effective platforms for ma…

Civilisational Data Mining

It’s a new expression I haven’t heard before. ‘Civilisational data mining.’

Let me start by putting it in some context. Every character, you or I have typed into the Google search engine or Facebook over the last decade, means something, to someone or perhaps ‘something,’ if it’s an algorithm.


In May 2014, journalists revealed that the United States National Security Agency, the NSA, was recording and archiving every single cell-phone conversation that took place in the Bahamas. In the process they managed to transform a significant proportion of a society’s day to day interactions into unstructured data; valuable information which can of course be analysed, correlated and transformed for whatever purpose the intelligence agency deems fit.

And today, I read that a GOP-hired data company in the United States has ‘leaked’ personal information, preferences and voting intentions on… wait for it… 198 million US citizens.

Within another decade or so, the cost of sequencing the human genome …
