s cars become more like PCs on wheels, what's to stop a hacker from taking over yours? In recent demonstrations, hackers have shown they can slam a car's brakes at freeway speeds, jerk the steering wheel and even shut down the engine . The hackers are publicizing their work to reveal vulnerabilities present in a growing number of car computers. All cars and trucks contain anywhere from 20 to 70 computers. They control everything from the brakes to acceleration to the windows, and are connected to an internal network. A few hackers have recently managed to find their way into these intricate networks.

Not computer networks, networks in general: Findings so far suggest that networks of networks pose risks of catastrophic danger that can exceed the risks in isolated systems. A seemingly benign disruption can generate rippling negative effects. . Those effects can cost millions of dollars, or even billions, when stock markets crash, half of India loses power or an Icelandic volcano spews ash into the sky, shutting down air travel and overwhelming hotels and rental car companies. In other cases, failure within a network of networks can mean the difference between a minor disease outbreak or a pandemic, a foiled terrorist attack or one that kills thousands of people.

How are VoIP networks weak and vulnerable to attack and catastrophic failure? Securing VoIP Networks, the new book by Peter Thermos and Ari Takanen, looks at VoIP infrastructure and analyzes its vulnerabilities much as the Open Web Application Security Project did for Web-related vulnerabilities and Mitre did with its Common Weakness Enumeration dictionary for software.

Conference delegates leave themselves wide open to attack. More than half of the computers used by security experts attending the RSA Conference on security lack the proper protection and may have been compromised, according to wireless security firm AirDefense. . The company scanned all wireless traffic on the first day of the conference and found a total of 623 Wi-Fi enabled notebooks and mobile phones. Some 56% of these devices were configured automatically to log-on to networks with common names such as 'Linksys' or 'T-Mobile', a feature known as an open access wireless account.

Apparently, no actual damage was done to the systems and the hackers' access was brief. But they "could clearly have done severe damage," says TruSecure analyst Russ Cooper. The amount of bandwidth they controlled "far exceeded" several hundred personal computers connected to the Internet via cable modems. Hackers have gained access to supercomputers and large computer networks at numerous university and research organization facilities in the last few weeks. The infiltrations, which are still under investigation, temporarily gave the attackers sufficient computing power to attack large portions of the Internet. .

It is no secret that wireless local area networks, or WLANs Latest News about WLAN, can be probed by anyone within range of their radio signal, leaving them vulnerable to eavesdropping, unauthorized access and even viruses. In short, most WLANs have security loopholes large enough to drive a truck through. WEP (wired equivalent privacy), is the security mechanism that comes standard with 802.11 products, but its days are short-lived. That is because a new standard -- Wi-Fi Latest News about Wi-Fi protected access, or WPA -- is on the way. In the meantime, however, vendors are not waiting for certification; they are building products to bridge the time lag and give WLAN administrators solutions now. The No. 1 security problem for WLANs is that a large number of enterprises do not activate their existing security systems, says Meta Group senior analyst Chris Kozup. .

When the Pentagon--no small potential customer--cracked down recently on the installation of wireless LANs, the industry sat up and took notice. Why? The inherent vulnerabilities of the technology. If you simply go to the nearest computer dealer and buy a $99 access point and plug it in, your wireless link will be insecure. But vendors are bringing out commercial equipment to make it easier to overcome the security problems that plague wireless LANs. They are splitting access points into two parts so that the 2.4- and 5.0-Gigahertz radio signals can be showered anywhere, but a second component behind the corporate firewall will arbitrate the access or movement of data.
