=== IN FOCUS: The High Risk of Using Open Networks =============
   by Mark Joseph Edwards, News Editor, mark at ntsecurity / net

Open networks are tempting, especially when you really need to send or
receive messages or gather some data quickly while on the road. But
don't let your guard down while using open networks (such as those at
conferences, coffee shops, or hotels), or you might fall victim to an
intruder. In fact, when using open networks, you should raise your
guard as high as you can, which might mean deciding not to use a
certain open network at all.

The decision whether to use an open network comes down to two simple
questions: Do you trust that you can get on and off the network safely;
and do you feel confident that your system is secure enough to
withstand potential zero-day exploits?

A good example of how high the risk is happened at the 2006 ShmooCon
conference. While using the conference's wireless network, a security
researcher's Mac laptop fell victim to attack. Even though the
researcher's laptop was secured as well as possible, the system was
broken into using a zero-day exploit. Unfortunately, the presenter was
not running any packet-capture tools at the time, so attempts to find
out how the break-in happened were fruitless.

Another case in point occurred only last week at the CanSecWest
conference in Vancouver, B.C., Canada. At the conference, an
interesting challenge was presented: Break into either of two MacBook
Pros running OS X and win the computer. TippingPoint (a division of
3Com) offered a $10,000 cash prize to enhance the challenge further.

Sure enough, someone broke into one of the MacBooks using a zero-day
exploit against the Safari Web browser. The winning challenger, Shane
Macaulay, worked with a friend, Dino Dai Zovi, who didn't attend the
conference. Zovi provided the exploit, and Macaulay executed it at
the conference by setting up a Mac server on the conference's wireless
network. He then had one of the conference workers enter a specific URL
into the MacBook's browser, which in turn connected to the server to
launch the exploit. That's all that was required for the MacBook to
become "owned."

The point of the latter example is that the same thing could be
accomplished by a bad guy lurking on a conference network or any other
open network. It doesn't matter what OS you use, the risks are
basically the same. Said otherwise, zero-day exploits exist for all
OSs, and it's often incredibly difficult to defend against the unknown.

If you feel you must use an open network, one way to help avoid falling
victim--to some extent anyway--is to use a virtual machine (VM)
configuration to perform whatever tasks you need to do. While a VM
might not completely protect your system, at least when you restart the
VM, its OS will come up clean, assuming of course that no one used a
zero-day exploit to compromise the VM software or OS image.

Another way to possibly protect your system is to use a bootable Live
CD, which you might know is basically a CD-ROM with a bootable OS. If
you're interested in finding a good Live CD, head over to FrozenTech
(at the URL below) where you'll find dozens that you can choose from.

While neither method I suggested is completely secure, at least both
methods make it much more difficult for an intruder to "own" your
computer.

As an aside, since I mentioned OS X in this column, I want to also
point out that Apple released a batch of 25 security patches last week.
So if you manage OS X systems, be sure to update them. You can learn
more about the patches at the Apple site at the URL below.

Take Control of Endpoints
   matrix42 introduced Empirum Security Suite, which protects
workstations and laptops with a firewall, intrusion prevention system
(IPS), application and file control, removable device control, and
wireless control.  Empirum Security Suite enforces a workstation's
specific policies whether the computer is on or off the network.
According to matrix42, Empirum operates at the kernel level, so after
you configure it by using the central management console, a user (even
one with administrator rights) can't disable or reconfigure it. Empirum
has behavioral technology and defends against information theft via
keylogging or spyware and other intrusion methods. For more
