More about your Hacker Exposure Check results

The Hacker Exposure Check tests whether ports commonly used by Internet applications are open, closed, or stealth

Understanding your results:
Open port An open port responds to port probes and acknowledges the port's availability. Open ports are dangerous because they're an easy and attractive means of entry for hackers.
Closed port A closed port is visible but not open to attack. Although this is a safe state, a hacker can use closed ports to detect the existence of your computer and potentially target it for attack.
Stealth port A stealth port is safest of all. Stealth means your computer doesn't respond to port probes and you are virtually invisible to hackers scanning the Internet for potential targets. Although this is a very safe result, a stealth port may cause performance problems for some Internet applications.

Your Results:
Port Description Status

ICMP Ping Ping. Ping is a network troubleshooting utility. It asks your computer to acknowledge its existence. If your computer responds positively to a ping, hackers are more likely to target your computer. Open port

21 FTP (File Transfer Protocol). FTP is used to transfer files between your computer and other computers. Port 21 should be open only if you're running an FTP server. Open port

22 SSH. TCP connections to this port might indicate a search for SSH, which has a few exploitable features. SSH is a secure replacement for Telnet. The most common uses of SSH are to securely login and copy files from a server. Closed port

23 Telnet. Telnet can be used to log into your computer from a terminal anywhere in the world. This port should be open only if you're running a Telnet server. Open port

25 SMTP (Simple Mail Transfer Protocol). A protocol for host-to-host mail transport. This port should be open only if you're running a mail server. Closed port

79 Finger. Finger is an Internet utility that allows someone to obtain information about you, including your full name, logon status, and other profile information. Closed port

80 HTTP (Hypertext Transfer Protocol). HTTP is used to transfer Web pages over the Internet. Port 80 should be open only if you're running a Web server. Closed port

110 POP3 (Post Office Protocol). Internet mail servers and mail filter applications use this port. This port should be open only if you're running a mail server. Closed port

113 Ident / Authentication. This service is required by some mail, news, or relay chat servers to allow access. A stealth result on this port could cause performance problems. Closed port

119 NNTP (Network News Transfer Protocol). A service used by News servers to distribute Usenet articles to newsreader applications and between other servers. Closed port

135 Location service (loc-srv). This port is used to direct RPC (Remote Procedure Calls) services to the appropriate dynamically mapped ports. Hackers can use this to determine which port is used by several Windows services. This port should not be visible from the Internet. Closed port

139 NetBIOS. NetBIOS is used for Windows File & Print sharing. If port 139 is open, your computer is open to sharing files over the Internet. Other components of NetBIOS can expose your computer name, workgroup, user name, and other information. To learn more about preventing connections to your NetBIOS ports, see: NetBIOS Information and Configuration Instructions Closed port

143 IMAP (Internet Message Access Protocol). IMAP is a sophisticated protocol for electronic mail delivery. This port should be open only if you're running an IMAP server. Closed port

443 HTTP over TLS/SSL. A protocol for providing secure HTTP communication. It should be open only if you're running a Web server. Closed port

445 Windows NT / 2000 SMB. A standard used to exchange Server Message Blocks, and can be exploited in multiple ways, including gaining your passwords. Closed port

1080 SOCKS. This protocol allows computers access to the Internet through a firewall. It is used when one IP address is shared among several computers. Generally this protocol only allows access out to the Internet. However, it is frequently configured incorrectly to allow hackers to pass traffic inwards through the firewall. Closed port

1723 PPTP (Point-to-Point Tunneling Protocol). This service is used for virtual private networking connections. Closed port

5000 UPnP (Universal Plug and Play). This service is used to communicate with any UPnP devices attached to your network. Closed port

5631 pcAnywhere. This port is used by Symantec pcAnywhere when in host mode. Closed port
