Security in Windows 7: Firewall and Networking

Like Rodney Dangerfield, Windows Firewall just don't get no respect. It
didn't evolve appreciably in the transition from XP to Vista. It does its simple job well, but its lack of ambition makes it a punching bag for reviews of other, better personal firewalls. I can't tell you how many times I've written sentences along the lines of, "Sure, Product X stealths all your ports against hack attack, but heck, even Windows Firewall can do that." Good news: It looks as if Windows 7 will pull the firewall out of its slump. Some new features are visible and functional even in the pre-beta I've got running on my test system, and there's a tantalizing suggestion of more to come.

Hangin' with My HomeGroup

The firewall exists to protect your network, and Windows 7 starts by making it easier to configure that all-important home network. When users hit network problems, they curse the firewall—and they're often right to. Windows 7 addresses the problem by taking over home network setup and making sure the firewall doesn't interfere.

At installation Windows 7 offers to create the cozy-sounding HomeGroup. As you add other networked Windows 7 computers, they'll be invited to join. They just use the same HomeGroup password. Having just one computer running the pre-beta, I didn't experience the sign-up process for additional computers, but it looks simple.

Computers in the same HomeGroup can share printers and specific libraries of files. By default they'll share pictures, music, videos, and documents, but you can limit those choices if you wish. There's an option to exclude specific folders. At the moment, the link to explain how you'd do this goes to an unfinished page. Fine: This is a pre-beta, remember?

You can also share media with other computers and devices on your home network, including computers not running Windows 7, and devices other than PCs. Microsoft offers the example of streaming music and videos to your Xbox 360. Apparently it works only with certain devices—itit didn't offer to connect with the Wii on my network. Time will tell whether HomeGroup actually makes home networking easier, but it looks good.

Where Vista distinguishes between Public and Private networks, Windows 7 splits private into Home and Work networks. HomeGroup is available only if you've chosen the Home network type. On a Work network, your computer can still see and connect with other devices on the network. A Public network (like the wireless at your favorite coffee shop) blocks access to and from other devices on the net, for your safety.(www.pcmag.com)
