This allows people to create thousands of websites that contain information that is based, inaccurate or wrong.

There is no organization that controls Internet and the Web.

This means that anyone can create web

pages and write what they want.

People or organizations can easily spread

information that is not true.

RELIABILITY OF

INFORMATION

+

• Look at the spelling and grammar of the information written. If a website has too many spelling mistakes, it is not a reliable source of information.

To identify reliable information people have to:

• Look for information in different websites; if all the sources have the same thing, the information is probably true.

• Research in websites that belong to trusted organizations. For example if the website address ends in .gov it is the government website of a country.

+Undesirable

Information

This software tries to prevent offensive and illegal information being accessed.

There are a lot of websites that contain offensive or illegal information

To avoid this type of information, some organizations, schools, governments, and some parents, use webpage filtering software.

+

• Think carefully about the keywords that you use to search with.

• Use the “safe search” feature on search engines, like Google.

• Don´t click the links that are shown in junk email.

If there is not a filtering software installed on a computer, people can take steps to

avoid undesirable information:

Security of Data Transferred

Using the Internet

To protect information, people should always encrypt sensitive or personal data that is sent or accessed on a public network, like the Internet.

+

To identify a secure website:•The URL (address) should begin with https://... (normal unsecure websites start with http://...•The web browser should show a closed padlock icon.

To access websites like online shopping or online banking websites, users need to enter personal information, including credit card numbers and social security ID.

These websites use encryption to keep information safe, and they are called secure websites.

+

•Using a firewall: This prevents illegal users from accessing a network.

To keep safe information that is transferred online people should:

•Use digital certificates: Transactions are digitally signed and authenticated when doing online banking.

•Install Anti Spyware: Prevents spyware from accessing a computer and getting personal information.

•Using encryption: Data is scrambled up, and the user must know a key to unscramble the information. This prevents people from understanding data.

•Using an ID, password or PIN: The code entered is compared with the one that is recorded on system. People must not tell anyone their password, and change it frequently. The password should not be easy to guess.

Phishing means sending fraudulent emails to trick people and make them reveal information about their bank accounts or any online account. Then the phishers use these personal information to enter the person´s bank account and steal their money.The emails sent by phishers look very convincing, they have the bank´s logo, and usually send an urgent message to scare people. If someone clicks the link in the website, they will be sent to a fake bank website. The information entered by the user would be then used by the phishers to empty the real bank account.

Phishing

+Pharming

Pharming means installing a malicious code on a computer to redirect or send to fake websites. Pharming is similar to phishing, but instead of deceiving the person, it deceives the computer. The purpose of pharming is to get personal details from people.

When pharming occurs, a person types in a normal URL, but the computer is tricked to show a fake website that looks authentic. When the person tries to login the fake website, the username and password are used to steal the money from the bank account.It´s difficult to detect pharming, because the user doesn´t know that something is not normal in the website.

+ E-mail Spam

To prevent spam people use email spam filters, that separate spam messages from normal messages.

Spam means sending or receiving junk or unsolicited emails: they are sent without being asked for. Spam emails usually contain advertisements for products.

Spam became a big problem and it is estimated that 97% of all email messages is spam.
