E-mail Safety Tips
Remember the good old days: To send a picture to your family, you had to put it in envelope, mark the envelope “Photos-Do Not Bend” (which, apparently in some languages means “Bend this”), then find their mailing address, hunt for stamps, try to guess how many to use, then wait 3-37 business days for them to receive it. You business owners out there, remember trying to get your client that important proposal, having to get everything typed up and signed before 4 pm to make sure it went out overnight? Then, remembering at 4:15 that you forgot to include that important page.
My how we have grown. E-mail is a truly invaluable tool. What would we do without it! Now, we use it to send pictures to friends and family instantly. We use it to request more information about that vacation we want to take. Office coworkers use it to communicate with one another and businesses use it to communicate with customers and vendors. E-mail is fun and very cost efficient. But, it is not very secure. It is one of the main ways of transmitting viruses and other malicious software from computer to computer. Also, it is possible for your e-mail to be read by someone other than your intended recipient. E-mail is really like sending a postcard through the mail. Anyone can read what you write on a postcard. Knowing that, you would never write “secret” stuff on a postcard and that same rule should apply to your e-mail.
This article is the second in our series “Protect your Data Online and in the Office”. Remember, a thief first needs your data in order to steal your identity. That is what we want to prevent. The first article in our series dealt with creating good, strong passwords. Now, we will offer some tips and suggestions that will help keep you safe while using e-mail. But first, where did e-mail come from?
A Very Brief History of E-mail
Very basic e-mail actually first appeared on scene in early 1960s. However, it only worked with a certain type of computer and so was not feasible for the masses. But then, in the early 1990s, the modern version of e-mail began to take shape. America Online and Delphi began to connect their corporate e-mail systems to the Internet and viola, the modern e-mail standard was born. Now anyone could send a certain number of e-mails each month for around $10 (can you imagine having to pay for e-mail?). Today, estimates on the number of e-mails send each day range from a little over 2 billion (yes, that is “billion”) to 60 billion. Wow! That is allot of communication. It also provides plenty of opportunity for unscrupulous people to spread viruses and harvest sensitive data. So, lets see how we can limit our risk while using e-mail.
E-mail Attachments
Be skeptical of attachments. Even if you know the person sending you the message, if you are not expecting an attachment, don’ t open it. The attachment may contain nasty little programs know as “letterbombs.” One of these could easily render your computer useless. The best course of action is to contact the sender and ask them if they sent you a file. They can then verify that it was indeed from them. Then, you can decide to open it or not. If you decide to open it, make sure your anti-virus software is operating and is up-do-date. This may be an inconvenience, but it is much better than possibly installing a trojan horse program or a virus.
