Hackers can attach viruses to files that will be downloaded using File Transfer Protocol (FTP) client software. After all, hackers can monitor unencrypted traffic going into and out of client systems and discover details like passwords used to access "secure" applications. This doesn't mean, however, that client systems provide a worry-free environment. Is it a client, a server, or both?Ĭlient systems, which merely explore the network looking for information, run the least risk because hackers can't penetrate them while they're connected. If you're concerned about the security of a system operating over the Internet, the first thing to look at is how that system interacts with the network. Just because NT has excellent internal security doesn't make it bulletproof on the Internet-just as a world-class boxer might not last three minutes in a back-alley street fight. The very fact that NT Workstations and Servers are operating over the Internet puts them at risk. But what risks do you run when you attach an NT Workstation or an NT Server to a TCP/IP network? Are TCP/IP networks inherently risky? And if they are, do those security weaknesses affect NT systems on the Internet? You bet they do. Embedded support for the Transmission Control Protocol/Internet Protocol (TCP/IP) network architecture allows NT systems to be easily integrated into large networks including the Internet. And although you can't see them, many Windows NT Workstations also connect to the Internet as client systems. If you've explored the Internet recently, you may have noticed that many Internet servers are Windows NT Servers.
