Deciding what software to install on a host — especially a server — involves sometimes difficult choices as you try to balance users' needs for services against security. In this exercise, your Unix server has a program called staprun that a user can exploit to get root/administrator privileges. So staprun clearly has to go. This utility can be removed by logging in as root and giving the command:
apt-get remove systemtap-runtime

The webserver on the workstation (WKSTA) also clearly needs to go. There doesn't seem to be any logical reason for it, especially since it hasn't even been changed from its default configuration!

Remove it as follows:

  1. Remote Desktop to the workstation (WKSTA) and log in as the Administrator.
  2. From the workstation, open the Command Prompt (cmd.exe) and execute appwiz.cpl to open the "Add or Remove Programs" window.
  3. On the left side of the pane, click on "Add/Remove Windows Components" to bring up the Windows Components Wizard.
  4. From this new window, uncheck the box next for Internet Information Services (IIS) and click Next
  5. Once it finishes, click Finish. You have just removed the webserver program from the workstation.
