Here are some tips and questions you should ask to help protect you when using social networking sites.
You don’t have to rely on “recommended” settings or default settings. Learn about the controls available and make your own decisions. It's okay to limit with whom you share your information. It is okay to not accept a friend request.
Consider who may have access to your profile: family, friends, friends of friends, your school, college admissions officers, and potential employers? Set the privacy and security settings to your personal comfort level for information sharing.
Create a strong, positive personal brand online for yourself online. Show your smarts, thoughtfulness, and mastery of the digital environment. This can help you with school admissions and during job searches.
What you post will be around for a long time. Think ahead and evaluate if what you post today is what you will want people to know about you in the future.
When you choose to share information with anyone in your networks, they can easily forward it or post. Make sure they will handle your information with care and trust. Avoid sharing compromising photos and information.
Combine capital and lowercase letters with numbers and symbols in a unique password for each online account. Passwords are personal information that should not be shared.
Your phone numbers, home address, full date of birth, travel plans, email address, class schedules, social security number, passwords, family financial information, bank or credit card numbers shouldn’t appear on your profile.
Post only about others what you would have them post about you. It’s the golden rule.
