DSL Modem User Manual

Appendix C Computer Security

Modem Security

If connecting to the ISP through Point-to-Point Protocol (PPP), be sure to pro-

vide the Modem 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.
