Cyberbullying Cyberbullying or online bullying is repeated, unwanted or cruel behavior against someone through computers, cell phones, gaming consoles, or other Internet-based means. The Internet is always “on,” opening the door for 24-hour harassment. Cyberbullies can be anonymous. They never have to confront their victims, they don’t have to be physically stronger and cyberbullies may be virtually invisible to parents and adults.

Look for warning signs your child may be the victim of cyberbullying – depression, lack of interest in school and friends, drop in grades and subtle comments that something may be wrong. If your child is the victim of cyberbullying, take action. By filtering email, instant messages and text messages, you can cut off many of the ways the cyberbullies contact your child. By having your child avoid the sites and groups where the attacks occur, he/she can ignore the bully. If harassment continues, change your child’s email address, user names and Internet account. If these steps do not stop the cyberbullying, contact the parents of the child who is behind the bullying, contact the school, and if the situation is not resolved, involve the police. It’s important to compile copies of harassing emails and postings to have evidence for authorities or the school, so they can take action. Look for signs that your child may be the cyberbully themselves – if they sign onto the Internet under someone else’s name, if they use someone else’s password without their permission, if they posted rude or mean things about someone else online, if they use bad language online, or if they changed their profile or away message designed to embarrass or frighten someone. Talk to your kids about cyberbullying and why it’s wrong and hurtful.

For the home user, however, password safety requires more than on-the-fly thinking. Pacheco suggests a system built around a main word for all instances. The distinction is that the name of the site is added somewhere. For example, if the main word is "eggplant," the password might be "eggyyplant" Yahoo, "eggplantgg" for Google or "wleggplant" for Windows Live. He suggests listing the variations in an Excel spreadsheet.

Hackers rely on a lot of methods. Some, Rogers said, employ "shoulder surfing." That means what it sounds like -- looking over someone's shoulder as that person is typing in a password

The type of hardware being used can be a clue, said Rogers, a senior technical staffer in the CERT Program, a Web security research center in Carnegie-Mellon University's software engineering institute. It's easy to find a default password, typically in the user's manual on a manufacturer's Web site. If the user hasn't changed the default, that's an easy break-in.
