The Internet offers vast possibilities for learning, making a living, and having fun—but it can also destroy reputations, empty bank accounts, and ruin lives. This program cautions students about potential hazards to their computers—not to mention their careers, finances, and futures—that exist online. Highlighting the importance of setting up a firewall and keeping one’s operating system up-to-date, the program provides straightforward advice about protecting against hackers, viruses, Trojan horses, spyware, adware, phishing emails, and other high-tech threats. Each concept is defined in user-friendly terms. More basic but equally vital steps like maintaining multiple passwords and not sharing personal information are also discussed. Commentary from experts, as well as questions from peers about the details of computer safeguards, will help students increase their online security. A viewable/printable instructor’s guide is available online. Correlates to National ISTE Technology Foundation Standards for Students.
