Patching confusion reigned in second half of 2003

Computer Weekly reports there was an average of 220 security vulnerabilities a month between July and December 2003, of which an average of 99 were of “high severity”, and 70% of which were easy to exploit, according to Symantec’s latest Internet Security Threat Report.

The findings of the report highlight growing concerns among IT users that implementing every software patch released is becoming an impossible task.

Symantec Internet Security Threat Report July-Dec 2003: Main points

- Blended threats increasingly target backdoors left by other attackers and worms

- Financial services, healthcare and power and energy sectors were the hardest hit by severe cyber attacks

- 2,636 new vulnerabilities – an average of 220 new per month

- 70% of new vulnerabilities are easily exploited requiring no exploit code providing opportunity for attackers to gain access to critical systems more easily.

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 …

The Big Steal

I’m not here to predict the future;” quipped the novelist, Ray Bradbury. “I’m here to prevent it.” And the future looks much like one where giant corporations who hold the most data, the fastest servers, and the greatest processing power will drive all economic growth into the second half of the century.

We live in an unprecedented time. This in the sense that nobody knows what the world will look like in twenty years; one where making confident forecasts in the face of new technologies becomes a real challenge. Before this decade is over, business leaders will face regular and complex decisions about protecting their critical information and systems as more of the existing solutions they have relied upon are exposed as inadequate.

The few real certainties we have available surround the uninterrupted march of Moore’s Law - the notion that the number of transistors in the top-of-the-line processors doubles approximately every two years - and the unpredictability of human nature. Exper…
