1 . What are social networking sites
Social networking sites, sometimes referred to as friendofafriend sites, build upon the concept of traditional social networks where you are connected to new people through people you already know. The purpose of some networking sites may be purely social, allowing users to establish friendships or romantic relationships, while others may focus on establishing business connections. Although the features of social networking sites differ, they all allow you to provide information about yourself and offer some type of communication mechanism (forums, chat rooms, email, instant messenger) that enables you to connect with other users. On some sites, you can browse for people based on certain criteria, while other sites require that you be introduced to new people through a connection you share. Many of the sites have communities or subgroups that may be based on a particular interest.
2 . What security implications do these sites present
Social networking sites rely on connections and communication, so they encourage you to provide a certain amount of personal information. When deciding how much information to reveal, people may not exercise the same amount of caution as they would when meeting someone in person because 1the internet provides a sense of anonymity. 2The lack of physical interaction provides a false sense of security. 3they tailor the information for their friends to read, forgetting that others may see it. 4they want to offer insights to impress potential friends or associates. While the majority of people using these sites do not pose a threat, malicious people may be drawn to them because of the accessibility and amount of personal information thats available. The more information malicious people have about you, the easier it is for them to take advantage of you. Predators may form relationships online and then convince unsuspecting individuals to meet them in person. That could lead to a dangerous situation. The personal information can also be used to conduct a social engineering attack. Using information that you provide about your location, hobbies, interests, and friends, a malicious person could impersonate a trusted friend or convince you that they have the authority to access other personal or financial data.
3 . Limit the amount of personal information you post
Do not post information that would make you vulnerable, such as your address or information about your schedule or routine. If your connections post information about you, make sure the combined information is not more than you would be comfortable with strangers knowing. Also be considerate when posting information, including photos, about your connections.
4 . Remember that the internet is a public resource
Only post information you are comfortable with anyone seeing. This includes information and photos in your profile and in blogs and other forums. Also, once you post information online, you cant retract it. Even if you remove the information from a site, saved or cached versions may still exist on other peoples machines.
5 . Be wary of strangers
The internet makes it easy for people to misrepresent their identities and motives. Consider limiting the people who are allowed to contact you on these sites. If you interact with people you do not know, be cautious about the amount of information you reveal or agreeing to meet them in person.
6 . Be skeptical
Dont believe everything you read online. People may post false or misleading information about various topics, including their own identities. This is not necessarily done with malicious intent; it could be unintentional, an exaggeration, or a joke. Take appropriate precautions, though, and try to verify the authenticity of any information before taking any action.
7 . Evaluate your settings
Take advantage of a sites privacy settings. The default settings for some sites may allow anyone to see your profile. You can customize your settings to restrict access to only certain people. However, there is a risk that even this private information could be exposed, so dont post anything that you wouldnt want the public to see. Also, be cautious when deciding which applications to enable, and check your settings to see what information the applications will be able to access.
8 . Use strong passwords
Protect your account with passwords that cannot easily be guessed. If your password is compromised, someone else may be able to access your account and pretend to be you. Limit usage of social networking sites to personal use only. Do not write about work issues. Always assume everyone in the world will be able to see what youre writing even if the site limits your post to your friends exclusively.
9 . Check privacy policies
Some sites may share information such as email addresses or user preferences with other companies. This may lead to an increase in spam. Also, try to locate the policy for handling referrals to make sure that you do not unintentionally sign your friends up for spam. Some sites will continue to send email messages to anyone you refer until they join.
10 . Use and maintain anti virus software
Antivirus software recognizes most known viruses and protects your computer against them, so you may be able to detect and remove the virus before it can do any damage. Because attackers are continually writing new viruses, it is important to keep your definitions up to date.
