    HP aims to throttle Net threats

    Computing giant Hewlett-Packard plans to announce two services this week aimed at slowing down fast-spreading viruses and immunizing networks against threats.
    One service, known as virus throttling, will limit the speed at which viruses and worms can spread by reducing the number of connections an infected computer can have to the Internet. A second service that HP intends to offer mimics medical vaccinations by placing devices within a network that will continually attack a company's computers with the digital equivalent of dead germs.

    The plans are part of HP's strategy for allowing customers able to quickly deal with changes in information technology, including security and Internet threats, said Joe Pato, distinguished technologist for HP Labs' Trusted Systems Lab.

    "We want to construct systems that are responsive to change," he said. Pato will describe the two services in a keynote presentation Thursday at the RSA Conference in San Francisco.

    The two techniques are the latest research developments that draw their foundations from treating digital systems like biological ones. Notably, IBM has researched ways to make computers and networks self-healing and has researched better ways of responding to digital attacks under its Digital Immune System project.

    While IBM has dubbed its overall strategy "On Demand Computing," HP is referring to its vision of the corporate information infrastructure as the "Adaptive Enterprise."

    The two services that HP plans to outline at the RSA Conference could help companies respond to fast-spreading threats and maintain their defenses against everyday attacks.

    Virus throttling slows down the spread of worms and viruses by placing a limit on the number of connections a PC can make to the Internet.

    Once they have installed themselves on a PC, worms such as MSBlast and viruses such as MyDoom spread quickly because they are able to send copies of their code to the Internet through a large number of connections. These connections are not the physical phone or cable line that connects a household to its Net access provider, but rather the software connections that link one computer to another. In studying the common behavior of such threats, Pato and others noticed that the worst worms and viruses created multiple connections.

    "Some of the things that were evident were that worms tended to generate a large number of new connections in a short time," Pato said. Users can't create such links nearly as fast as automated software, so limiting the number of connections that can be established does not hobble the PC but can dramatically reduce the speed at which a virus spreads, he said.

    In many ways, virus throttling attacks a common denominator in the spread of viruses in both the computing and the real world: Diseases spread farther and faster with improvements in transportation. In the real world, expanded trade routes helped spread the bubonic plague in the 1300s and airplanes contributed to influenza pandemics.

    Similarly, viruses first hitched rides on infected files carried on computer disks and then spread faster and wider with the advent of e-mail. Worms hastened their spread by establishing direct computer-to-computer transfers through vulnerable services. The first example of a flash worm, Slammer, spread throughout the Internet within minutes.

    HP's throttling service could either run on a device on the customer's network or as a modification to a computer's operating system.

    The company's second service will likely run on one or more network devices. Rather than try to prevent attacks, the device will constantly attack computers on a customer's network.

    However, like the dead viruses and bacteria in a vaccination, the attacks used by the Active Countermeasures service will be benign. Rather than compromising the target computer, they will instead run a simple program that notifies the system's administrator that the computer needs to be patched.

    The technique will also help to lock down the estimated 10 percent of devices on corporate networks that the company does not know about, said Pato. Such "black holes" in the networks can be weak points during an attack.

    "There are a number of systems that aren't known to administrators, that aren't part of the asset management system, and aren't regularly maintained," he said. "Here we take exploit code that is taking advantage of a vulnerability and use that to put mitigation code on the machines."

    When a new attack--also called an "exploit"--is seen by HP, the company will sterilize the code, so that it doesn't pose a danger to customers. Then, the company will ship a new version of the code out to the devices on customers' networks, which then attack the local computers with the benign attack. Any computers that are vulnerable will run the mitigation code, a small program that could display a message to the administrator or start the computer's patch program.

    "It will take some action, but that action is chosen from a set of benign responses," Pato said.

    HP plans to test the two services this year in small trials and then roll out these and other services by the end of the year, he said.

    There are already scripts out there that do this that are being used on honeypots so the attacker that compromises a box can't attack others from that box... and helps cut down on the amount of "damage" that can be done towards other boxes from the compromised host.

    The company's second service will likely run on one or more network devices. Rather than try to prevent attacks, the device will constantly attack computers on a customer's network.
    Great... so an automated nessus?
    Quitmzilla is a firefox extension that gives you stats on how long you have quit smoking, how much money you\'ve saved, how much you haven\'t smoked and recent milestones. Very helpful for people who quit smoking and used to smoke at their computers... Helps out with the urges.

    Hmmm

    And I suppose that SCO will claim ownership of the original code

    As pointed out it is not "new" it is marketing hype............I have been suggesting Yariv Kaplan's mail protection system for some time on this site, also I updated something the other day and it wanted to know how many mails to send before alerting me, I believe it was McAfee!

    Firewalls will block net connection attempts, as will other software (e-safe? for example)

    Or is this a sinister plot to de-skill systems administration in the eyes of CEOs and CIOs

    just my initial paranoias
