Remove anonymous access from IIS and folders to improve security

If you set up Windows 2000 Professional systems to host a Web site with IIS, consider removing

anonymous access in IIS to provide better security--particularly if those systems are connected

directly to the Internet. Windows 2000 Professional systems don't make good Web servers because

of their limitation to a maximum of 10 concurrent users. For that reason, Windows 2000

Professional systems are most useful in small workgroups, where anonymous access isn't really

necessary.



In situations where you do need to provide access to a Windows 2000 Professional system's folders

for anonymous use, remove anonymous access from the computer itself. Then, add a virtual

directory on a Web site hosted by a Windows 2000 Server and point the virtual directory to the

folder on the Windows 2000 Professional system that contains the data you need to share. When

you create the virtual directory, you can specify the account credentials on the Windows 2000

Professional machine that the IIS server will use to retrieve the data. The result is that the data is

anonymously available but not directly from the Windows 2000 Professional machine.



To remove anonymous access from IIS, open the IIS console on the Windows 2000 Professional

computer. Right-click the default Web site and choose Properties. Click the Directory Security tab

and then click Edit in the Anonymous Access And Authentication Control group. Clear the

Anonymous Access option and click OK. Click OK to close the site's property sheet.



You should also consider changing the default permissions on the computer's Inetpub folder, as

well. By default, the Everyone group has Full Control of the folder and child folders. Think about

creating a security group and giving only that security group access to the folder (along with the

system and administrators). Users of that security group will still be able to access the Web site

hosted by the computer by providing a user account that belongs to the group.
