Always Look on the Bright Side

I don’t wish to appear alarmist but on the one hand, you have Sir John Stevens warning us that a terrorist attack on London is inevitable and on the other, there’s talk among the IT security vendors, among them Symantec, of a ‘Zero Day’, ‘blended’ threat being imminent.

On the heels of the fuss last month surrounding the escape of Microsoft’s older source code into the wild, a “zero-day” blended threat, say Symantec, could target a potential vulnerability before that vulnerability is discovered and a patch made available. If such an outbreak occurs, the results could make Blaster look like a bad case of the sniffles in contrast with a raging flu pandemic.



Added to this, The Computer Virus Prevalence Survey found that last year, almost a third of the businesses polled worldwide had suffered a virus "disaster," defined as twenty-five or more computers infected by a single virus in the same incident. The survey indicated that antivirus software isn't a complete defense again the risk of infection. And it claims that almost all of the companies surveyed said that at least ninety percent of their desktops have antivirus protection, but still a third of the companies suffered virus disasters.

As many experts have predicted, the payloads being carried by viruses are showing signs of becoming more destructive. Netcraft reports that a Slammer-like worm dubbed Witty is spreading rapidly this week, generating large amounts of network traffic and leaving ruined computers in its wake. The worm, say Netcraft, exploits a weakness in the widely-used Black Ice security products, and is not detected by antivirus software, as it resides in memory. When an infected system is rebooted, Witty deletes a randomly chosen section of the hard drive, rendering some machines unusable.

Symantec, in its latest Internet Security Threat Report, warns that the Windows operating system uses components that are common to both corporate and consumer environments. Due to their extensive use, vulnerabilities in these components may make rapid, widespread severe events more likely. It also warns that client-side vulnerabilities in Microsoft’s Internet Explorer are on the rise. These, it says, may allow attackers to compromise the systems of client users who unwittingly visit malicious Web sites. In the past six months, researchers discovered thirty-four vulnerabilities in Internet Explorer.

Even bookies aren’t safe in cyberspace. A joint Netcraft and BBC investigation has revealed that in the Sport of Kings, ‘knobbling’ the jockey or his horse is a crime of the past Instead, organised crime is using new methods to achieve its goals. The UK's top twenty betting sites have suffered thirty-three separate outages since March 1st, among them reportedly William Hill, Betdaq, Totalbet and UKBetting who have admitted being the victims of Denial of Service (DOS) attacks or received extortion demands by criminals prior to the start of the Cheltenham Festival on 15th March.
Ironically, as a consultant, in the information security and computer crime space, I’m restricted in what I can write, by client confidence and non-disclosure agreements. I can however express my opinion that in some areas of the economy, these matters give rise to more concern than many of us might think they do and industry is short on immediate solutions to what we might call ‘The inevitability problem’.

Longer term, there’s industry optimism over the information security response to today’s problems but the future is a long way away in Internet terms and in the present, there’s a pervasive pessimism, much like that felt by ‘dug-in’ troops waiting for the enemy’s next artillery barrage and wondering if their foxholes are deep enough

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…

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…

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 …
