Appendix c Computer Security

Modem Security

If connecting to the

ISP

through Point-to-Point Protocol (

PPP

), be sure to provide

the Modem with an administrative password. If a password is not set, someone
on the Internet can access the Modem and change its configuration or steal your

PPP

login name and password. For instructions on setting the password, see the

“Advanced Setup” chapter.

If connecting to the

ISP

through bridging mode, the Modem should be safe from

unwarranted and illegal intrusion.

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 “backdoor” 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.
