Service Port Table

Service	Ports	Status	Additional Information
FTP DATA	20	CLOSED	This port has responded to our probes. This means that you are not running any application on this port, but it is still possible for someone to crash your computer through known TCP/IP stack vulnerabilities.
FTP	21	OPEN	File Transfer Protocol is used to transfer files between computers. A misconfigured FTP server can allow an attacker to transfer files, trojan horses, and virus programs at will.
SSH	22	BLOCKED	Secure Shell, a encrypted type of telnet. If misconfigured it can allow for brute-force attacks on your administration account.
TELNET	23	BLOCKED	Telnet is used to remotely create a shell (dos prompt), this can allow an attacker to control your system as if he was sitting in front of it.
SMTP	25	OPEN	SMTP is used to send email acrost the internet. This allows an attacker to verify user accounts on your system, send anonymous (spam) email, or even access files on your hard drive.
DNS	53	BLOCKED	none
DDC	59	BLOCKED	Used mainly by file transfer and chat programs.
FINGER	79	BLOCKED	Finger offers information about who is currently logged in to your computer.
WEB	80	OPEN	HTTP web services publish web pages. A misconfigured web server can not only offer an attacker needed information about his target, but it can allow for various security breaches.
POP3	110	BLOCKED	Post Office Protocol is used to receive email. It can be used by attackers to create fake email addresses, execute programs, and even intercept your private email.
IDENT	113	BLOCKED	Ident is often used for IRC (chat), but also provides information about your system and who is using it.
NetBIOS	139	BLOCKED	NetBios is used to share files through your Network Neighborhood. If you are connected to the internet with this open, you could be sharing your whole hard drive with the world! This is a very dangerous port to have open.
HTTPS	443	BLOCKED	Secure Web Servers are often used by banks and online vendors.
Server Message Block	445	BLOCKED	In Windows 2000, Microsoft added the possibility to run SMB directly over TCP/IP, without the extra layer of NBT.
SOCKS PROXY	1080	BLOCKED	Socks Proxy is an internet proxy service, many IRC servers will not allow you to log in if you are running an unsecured socks proxy.
SOURCE PORT	3131	BLOCKED	This is the port you are using to communicate to our Web Server. A firewall that uses Stateful Packet Inspection will show a 'BLOCKED' result for this port.
WEB PROXY	8080	BLOCKED	HTTP Web Proxy allows other people to bounce their web browser off of your computer to fake their real IP address to web servers.
