21
FTP
OPEN! FTP servers have many known security vulnerabilities and the payoff from exploiting an insecure FTP server can be significant. This system's open FTP port is inviting intruders to examine your system more closely.


23
Telnet
OPEN! Telnet provides a remote command prompt window which allows remote systems to be configured and controlled. Any system that appears to be offering a Telnet connection — like yours is right now — is offering the potential for total command-level access. Since a surprising number of Telnet servers are known to have no password, this open Telnet port will be attracting a LOT of the wrong kind of attention. If your network contains a residential NAT or DSL router, it may be that its "WAN-side" management interface is open and accepting connections. No matter what the cause, you should immediately attend to this open Telnet port.


80
HTTP
OPEN! The web is so insecure these days that new security "exploits" are being discovered almost daily. There are many known problems with Microsoft's Personal Web Server (PWS) and its Frontpage Extensions that many people run on their personal machines. So having port 80 "open" as it is here causes intruders to wonder how much information you might be willing to give away.


443
HTTPS
OPEN! The presence of this secure web port in your system implies that this system is establishing secure connections with web browsers. The number one reason for doing this is the transmission of credit card information. This implies that the successful intruder could access the web server's credit card database and score bigtime. This is a VERY bad port to have open unless you are actually conducting secure web commerce!
