What would you do if you ran the netstat command on your desktop computer and discovered port 80 was in use, but you did not have a Web server running on that computer? Why should you be concerned?
What will be an ideal response?
An open port 80 on a computer indicates that a Web server is running. If I saw this, I would run the netstat command with the-ano switch to determine what process is using port 80. Then I would determine what program name is associated with that process (one way to do this is with Windows Task Manager), and then I would take steps to remove this program. I would be concerned about this because obviously a malicious program is running as a Web server on my computer, probably serving up my personal data to someone on the Internet.
