A social network service focuses on building online communities of people who share interests
and/or activities, or who are interested in exploring the interests and activities of others.
National Cyber Alert System
“Social networking sites…build on the concept of traditional social networks where you are
connected to new people through the people you already know.”“Friend of a Friend”
Web 2.0
technology that “allows users to interact with others and to change website content, in contrast to

The Bad and the Ugly
Personal information could get in the wrong hands.Phishing scams, viruses and spyware may
spread through social networks.Once you’ve posted something, others can copy it or it may exist
in cache, so that even if you delete it, it may still exist and is out of your control.
Antisocial? If you spend all your time on the computer
– Internet provides sense on anonymity.
– Lack of physical contact may give false sense of security.
– People may post information for friends to read, forgetting that others may see it.
Examples
The case of a person asking for emergency money while impersonating a Facebook user to
her friends
/>Also the British MI6 chief that was exposed by his wife’s Facebook pictures:

How can you protect yourself?
Keep private information private
– Do not post address, ssn, phone number, financial info, your schedule, full birth date
– Be careful not to display information used to answer security questions (e.g., favorite pet,
mother’s maiden name)
Professional Practices in Information Technology
CSC 110
Use caution when you click links
Be careful about installing extras on your site
Be wary of unknown friends (strangers)
Google yourself
Don’t blindly connect
Trust your gut instinct
Use and maintain antivirus software
Use strong passwords
Don’t use the same password for a social networking site and for your email
Remember social networking sites are a public resource – like a billboard in cyberspace
Evaluate sites privacy settings
– Lock down your profile information to people you accepts as a friend. That way no one
can read your personal information unless they are an approved friend
Be skeptical
Protect your children
“It’s 10 p.m., do you know where your children are?”
– “And who they are talking to online?”
Age limits on some social networking sites
– Facebook and MySpace open to people 13 and older
– Twitter open to all
Talk to children about online safety. Tell them to keep personal information private. Explain
what personal information is (address, ssn, phone number, schedule, birth date, etc.), and to
not share personal information of their family or their friends either.

work, hang out or other info that can be used to identify or locate them offline.Warn them to
only be “friends” with people they actually know and are friendly with in real life.

– Remind them that once they post information online, just because they delete it, it might
not be really gone.
