Controlling your network, NTFS security part 3

Today I am going to conclude (I think) this series with an overview of using NTFS to establish greater security for your data on networked machines, and greater control over what is and what isn’t shared with others. A few simple adjustments will enhance your security whether you have a home network, or just a single computer connected to the Internet.

Tip of the day: [for users of Windows 2000, XP Pro, XP Media Center Edition] Gain control by turning off Simple File Sharing and using NTFS permissions. I want to start out by demonstrating how to turn off the default method Windows uses to make files available to other devices (known as “Simple File Sharing”), which is a valid move to make even if your PC is not connected [“networked”] with any other machines at this time — because the “Internet” is one big network and if you use it, you’re connected. Simple File Sharing makes everything available to everyone.

Begin by opening any folder, My Documents, whatever, and look in the top menu bar, and select Tools. Now click on the bottom choice — “Folder Options”. Select the View tab.

Deselect (uncheck) the bottom option “Use simple file sharing (Recommended)”. I understand that word “recommended” might throw you, and make you hesitate. In reply, the answer is, times have changed. Today we must be more cautious. However, realize that you can reinstall Simple File Sharing simply by ‘checking’ it again at any time.

Those of you who do not have a small network at home are done for today — class is dismissed –but if you do have machines that share a printer and/or files, keep reading to learn how to re-establish communications.

First, decide what it is you wish to share, and then decide with whom, because NTFS allows for almost total control over the what/who/when/where and how of “resource” sharing on your network. I will use my My Music folder for my demonstration, but the same steps are applied to anything you wish to make available, whether it’s a device like a printer or DVD burner, or a single file.

Place a check in the box labeled “Share this folder on the network” and either accept the “share name” (not the same as renaming) Windows gives it, or create your own name, and then click “Apply” and then “OK”.

Now the icon has changed to show that this folder is now being shared to other users and computers, and it will appear in the Network Neighborbood area of all the machines on your network. Go to another PC, open Network Neighborhood (or, “My Network Places”), double-click on it and it will look and function as if it were actually a part of that computer’s files. This allows you to play songs on one machine while they are actually stored on another (so you don’t have to have copies stored on each machine — wasting hard drive space).

I’m out of time, so tune in again tomorrow for a discussion on Permissions.
