Virus/Worm Removal Tools

  • McAfee AVERT Stinger "Stinger is a stand-alone utility used to detect and remove specific viruses. It is not a substitute for full anti-virus protection, but rather a tool to assist administrators and users when dealing with an infected system."
      
  • Symantec Removal Tools "Symantec Security Response has developed tools to automatically conduct what would often amount to extensive and tedious manual removal tasks. If your system has become infected, the tools listed (in their site) should aid you in repairing the damage."

Safe practices 

  • use SSH rather than Telnet to access resources on a computer
    SSH - Google's Directory
     
  • use secured FTP (sftp) rather than ftp for downloads from a computer (If you have a server, make secured FTP available on your servers and encourage users to use secured FTP rather than FTP for downloads)
    Secure FTP - Google Search
     
  • keep your machines updated with the latest patches
    Windows Update - Microsoft.com
     
  • have a personal firewall installed on your computer (Select the option whereby all Internet communication stops when computer is locked or goes to screen-saver)
    Personal Firewall - Google's Directory
     
  • disable your computer's network card if you are not going to access the network... enable it when you are going to use the network...
     
  • use strong passwords and do not type them while someone is watching
     
  • avoid using your computer with administrator privileges
     
  • disable file-sharing options

Some of the responsibilities of network users

A Summary of UTBTSC Network Use Policies

What is restricted on the network?

We cannot go into the detail of how firewalls and routers are configured on campus, however, there are certain restrictions that may be in place in future that will impact network users. Some of these are as follows:

  • A network port will be locked to a certain "registered" MAC address (get separate network connections if you are currently using a switch or a hub)
  • An assigned IP may only be used on its designated device with a certain MAC address
  • 802.1x authentication may be implemented. This will require a user to enter the assigned username/password to access the network
