Distingushing between real and spoofed emails

Another name for a fake website is "spoof".

Two internet services Phisers use to carry out internet fraud are E-Mail and the world wide web.

Phishers use fake statements in their e-mail that they may send out.

Phishers may ask for personal details that no genuine institution would request in an e-mail e.g. PIN numbers or passwords to accounts.

Phishing e-mails are not personalised for example they will never use your forename or surname in the e-mail. They cannot do this because they have to send the same e-mail to many different people.

Most banks (and other financial organisations, such as Paypal) use secure web sites. You can recognise these by the use of https://, rather than simply http:// in the URL. Notice the extra letter "s". Secure web sites also display a padlock icon in the status bar at the bottom of the screen.

Witholding personal information

Proxy-server solutions

Proxy ServersThe idea of a proxy is authorising someone to take your place or to do something for you.A proxy server is one that acts on behalf of another server, usually for Web related purposes.A proxy server allows internal users to get web pages from web servers without having to communicate with them directly.Only the firewall-protected proxy server is allowed to connect to the Internet. This process is invisible to users and is used to maintain network security

Installing and configuring antivirus software

Before you install AntiVirus:

  • Log in with a user name and password for an account with administrative privileges.

  • Disable or uninstall all other anti-virus and firewall applications that may interfere with the installation process.

Installing antivirus software:


1) Go to the BevoWare download site and select the appropriate version of Norton AntiVirus (NAV) for your version of OS X. If you are using OS X 10.4 (Tiger), download NAV 10. If you are using OS X 10.3.9 or earlier, download NAV 9.


2) Double-click the downloaded disk image file (.dmg).


3) Double-click the Norton AntiVirus icon and follow the instructions in the installation wizard to complete installation.


4) Reboot your machine when installation is complete.


5) Drag the Norton AntiVirus installer and the downloaded file (ending in .sit or .dmg) to the Trash, then empty it.

Legal Aspects

One of the most controversial aspects of the Internet has been the growth of peer-to-peer (P2P) file sharing systems, which allow users to share files, including songs, movies and software with others.

Some file sharing systems are:
  • Kazaa
  • LimeWire
  • Bit Torrent
  • eMule

Record companies, movie producers and software vendors claim that file sharing deprives both companies and artists of income and future productions, but many users claim that it gives them access to materials they would otherwise be unable to afford.

Many of the files found on file-sharing services are copyright and should not be uploaded or downloaded without the consent of the author or copyright holders.

High-street cybercafe company easyinternetcafe was fined for allowing users to download music files and burn them onto CD.

Why you should avoid P2P

Reasons you should avoid P2P are:

  • Downloaded files often turn out to contain a virus or have spyware
  • Downloaded files may be faulty and do not operate as they are meant to
  • Downloaded software may not be able to obtain support from the software vendor when they require it.

There are a number of legal download services, some of these are:

Some of these sites are free, but you have to pay for some of them. A site that is free is BBC iPlayer it lets you access television programmes via your PC and you can listen to the radio and live streaming.

Internet Defences

The most important defences for Internet use are knowledge and awareness. You should use these five rules to help keep your system safe:

1) Always be suspicious when you are using the internet.
2)Keep your password safe and only give confidential information to trusted sources.
3) Never go on-line without your system being fully protected and use up-to-date internet safety software.
4) Internet attacks and threats are on the increase, therefore it is vital that you know what the latest threats are.
5) Keep your main operating system files up to date by regularly downloading patches and security updates.

Passwords

A password is an important element of Internet defence. It is important to have a strong password that other people cannot easily guess. Strong passwords should contain a mixture of letters, numbers, other characters and upper case letters.

Weak or bad passwords are easy to guess and can result in your system being accessed.
Examples of bad passwords are things like your favourite band, your favourite TV programme, your pets name etc.

Phishing

Phishing is the Internet word for Fishing. You may have used the phrase "fishing for information". This is essentially what phishing is, but applied to the Internet rather than talking to someone face-to-face.

How to prevent it:

Beware of e-mails that ask for confidential information. Phishers will ask to be e-mailed personal information that no genuine institution would request in an e-mail, eg: PIN numbers or passwords to accounts.

Beware of e-mails that are not personalised. Phishing e-mails are very rarely personalised, for example, they will never use your forename or surname in the e-mail. They cannot do this because they have to send the same e-mail to many different people.

Identity Theft

Identity Theft

This is an extremely serious Internet threat which is becoming more common. The fraudsters use many techniques, such as phishing and spoofing (sending e-mails from false addresses) to obtain information about potential victims.

If you were a victim of identity theft you could:

Have money taken out of your account
Someone could apply for credit cards on your behalf or they could go buy something and you would get the bill.

Grooming

Grooming is another extremely serious Internet threat that is causing great concern. This type of threat is aimed mainly at young people. Typically, an older person will use the Internet and its services, particularly chat rooms and social networking sites, to communicate with younger people. The groomer will not give accurate information about themselves and in many cases will pretend to be a younger person.

How to prevent it

Put a computer in a family room and have a parent monitor check it.

Talk to them about the dangers of being in a chatroom

If you are meeting up with them take someone with you

Don't give out personal details

speak to your friends about it

Malware

Malware is short for malicious software, it is a general term used to cover a wide range of programs that are purposely designed to degrade, attack or prevent the intented use of a computer.

Spyware programs are hidden among other programs or can be unwittingly downloaded to a user's system when certain websites are visited.

Adware is any software that causes unwanted adverts to appear when a user is using their system.Sometimes these adverts appear as pop-up boxes that cause other pop-up boxes to appear even when the user tries to close them down.

Key Loggers are programs designed to capture and record every key you press, including your passwords and confidential information, such as bank account and credit card details.

Rogue Diallers are a type of computer software used by unscrupulous vendors of adult material on the Internet.The rogue dialler software, once downloaded, acts in a similar way to a virus, but with the purpose of disconnecting a system's modem from its usual Internet Service Provider (ISP) and reconnecting it to another ISP.
