Rumors, lies and innuendo spread far, wide and fast on the Internet

A lot of information on the internet that we can believe it or not. We should be able to choose what is right and wrong, do not be too easy to believeeverything on the internet.

Information research is performed in many different ways throughout the Internet. Once an information is found, the assessment of its relevance and trustiness happens through objective criteria and on the premise of subjective factors. What are such criteria and factors?  And how are they changing in a growing social connected net? A typical situation: You sit with friends together and discuss; a fact is cited, but you do not believe it and want to prove it is wrong, so you quickly check it  in the Internet. We increasingly rely on our digital backbone, which now it is even ubiquitous available through mobile phones. The net becomes our extended memory – not in any case it is easy to find an answer quickly, but is getting easier thanks to sources such as Wikipedia.

Example, we can search everything in internet for our assignment. But not all we get from internet is right. 

We can discuss about wikipedia, wikipedia give a lot of information but wikipedia have a shortage. people can edit the information in wikipedia and change it. So don't everything in there, we must search other references. 

Another example is internet fraud. 

The Internet is a useful way to reach a mass audience without spending a lot of time or money.  A website, online message, or “spam” e-mails can reach large numbers with minimum effort.  It's easy for fraudsters to make their messages look real and credible and sometimes hard for investors to tell the difference between fact and fiction.  That's why you should think twice before you invest your money in any opportunity you find online.

We must be careful because many criminal incidents on the internet. Such online shop that ask your credit card number. We must know that online shop really trustworthy or not.

Here are a few suggestions on ways to keep your personal information and money more secure when you go online:

Beef Up Your Security. Personal firewalls and security software packages (with anti-virus, anti-spam, and spyware detection features) are a must-have for those who engage in online financial transactions.

Use a Security Token (if available). Using a security token can make it even harder for an identity thief to access your online brokerage account. 

Be Careful What You Download. When you download a program or file from an unknown source, you risk loading malicious software programs on your computer.

Use Your Own Computer If You Can. It's generally safer to access your online brokerage account from your own computer than from other computers.

Don't Respond to Emails Requesting Personal Information.Legitimate entities will not ask you to provide or verify sensitive information through a non-secure means, such as email.

Be Smart About Your Password. The best passwords are ones that are difficult to guess. 

Use Extra Caution with Wireless Connections. Wireless networks may not provide as much security as wired Internet connections. 

Log Out Completely. Closing or minimizing your browser or typing in a new web address when you're done using your online account may not be enough to prevent others from gaining access to your account information.
