Appendix c Computer Security
Modem Security
Be sure to provide the Modem an administrative password. If a password is not set,
someone on the Internet can access the Modem and change its configuration. For
instructions on setting the password, see the “Advanced Setup” chapter.
Computer Security
To protect the valuable information on the computer, review the following topics.
These topics cover software programs and operating system features affecting the
security of the computer’s data.
Anti-Virus Programs
The computer should have an anti-virus program, and the virus definitions should
be updated on a regular basis – at least once a month.
E-Mail Attachments
Never run a program received as an attachment to an E-mail message unless the
program is known to be safe. A program from an unknown source can delete all
the files on the computer’s hard disk or install a “back door” software application
that lets people on the Internet gain access to the computer without permission.
Internet Browsers
Always exit the Internet browser (Internet Explorer or Netscape Navigator, for
example). Never “minimize” the browser or leave it open in the background.
Breaking into a computer is easier when an Internet browser is running.
Network Applications
Network applications (such as software programs) that allow remote access to the
computer also make the computer vulnerable to access from other people on the
Internet. If using a network application that allows remote access, consider install-
ing a firewall.
