Hewlett-Packard has demonstrated how computer virus technology can be turned around to protect business networks against hackers and worms.

The company is researching new virus-like security technologies that are designed to identify vulnerable machines on company networks and shut them down before malicious code strikes.

HP revealed this week that it had used the approach to protect thousands of machines on its network two days before the Blaster worm struck.

The code, developed by HP’s security research labs in Bristol, effectively saved the company from an infection that cost organisations around the world hundreds of millions of pounds to fix.

Although the technology is still at an early stage, HP sees it as a potential solution to the difficulties companies face ensuring all the machines on their network are patched, often at short notice, against the latest vulnerabilities.

That's kind of interesting. One of my sons (who doesn't know computer code from any other kind of language) once suggested something similar. Too bad he's not the one with the head for science (that's his brother...but he's attracted to physics). This one is current enamoured with horticulture (at least the lawn will look nice).

 

Just browsing the links from my favourites and came across this http://www.citi.umich.edu/u/provos/honeyd/msblast.html They describe how they used honeyd honeypot software to grab the msblast code then modify and use the modified code to cure infected machines on an internal lan. All sounds very similar to what HP have done.

 

It also sounds like one of those ideas that's so simple, it's positively genius.
