Actiontec USB/Ethernet DSL Modem User Manual

Modem Security

If connecting to the ISP through Point-to-Point Protocol (PPP), 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 or steal your PPP login name and password. For instructions on setting the password, see “Changing the Admin User Name and Password” on page 32.

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 “back door” software application that lets people on the Internet gain access to the computer without permission.

Web Browsers

Always exit the Web browser (Internet Explorer or Netscape Navigator, for exam- ple). Never “minimize” the browser or leave it open in the background. Breaking into a computer is easier when an Internet browser is running.
