Internet security

All data travels through the internet in a readable format unless it is encrypted. SSL stands for Secure Socket Layer; this is the technology which allows your computer to communicate over the internet privately. SSL turns the information into a code (encrypts it) so that it cannot be read by unauthorised people. You may have seen SSL on banking websites where you are required to enter private financial information. You will know when you are on an SSL-supported website because you will see a little padlock sign on the lower frame of the browser window, and the internet address of the site will begin with HTTPS rather than HTTP. It is a good idea to use SSL for your email too, if possible. It will encrypt your login details (so that no one can get hold of your password) and your outgoing email so that it cannot be intercepted on the way to the recipient. If you are using email software (where your email messages are downloaded straight to your computer) such as Thunderbird or Microsoft Outlook, it should be set to use SSL – this needs to be agreed with your server. For webmail accounts, such as Gmail and Yahoo, you will probably also have to enable SSL, either as a preference in your account settings or by typing in the HTTPS manually (by logging in to https://gmail.com instead of http://gmail.com). You should always make sure that your connection is secure before logging in, reading your email, or sending a message.
