How Encryption Works . Ordering something over the Internet, whether it's a book, a CD or anything else from an online vendor, or signing up for an online account, requires entering in a good deal of sensitive personal information. A typical transaction might include not only our names, e- mail addresses and physical address and phone number, but also passwords and personal identification numbers (PINs). The incredible growth of the Internet has excited businesses and consumers alike with its promise of changing the way we live and work.
It's extremely easy to buy and sell goods all over the world while sitting in front of a laptop. But security is a major concern on the Internet, especially when you're using it to send sensitive information between parties. Let's face it, there's a whole lot of information that we don't want other people to see, such as: Credit- card information. Social Security numbers. Private correspondence. Personal details. Sensitive company information.
Many routers provide WPA2-PSK (TKIP), WPA2-PSK (AES), and WPA2-PSK (TKIP/AES) as options. Choose the wrong one, though, and you’ll have a slower, less-secure network. Tomorrow is Lipstick Day and M.A.C. You don’t have to buy anything, just show up at one of their U.S. How secure is the Internet for sending sensitive information? Learn all about encryption, authentication, hash algorithms and more.
Bank- account information . A simple but straightforward security method is to only keep sensitive information on removable storage media like portable flash memory drives or external hard drives. But the most popular forms of security all rely on encryption, the process of encoding information in such a way that only the person (or computer) with the key can decode it. In this article, you will learn about encryption and authentication. You will also learn about public- key and symmetric- key systems, as well as hash algorithms.
Should you avoid external hard drives that boast built- in encryption? I got thinking about this question today. Why do hard drive manufacturers add useless hardware encryption to external drives?“Why, that should be obvious, Robbie; it’s because we are security conscious and want to protect our data from prying eyes,” you say. It boasts “2. 56- bit AES Encryption”. Wow, sounds safe!
So you plug in the drive to your computer, and place your private stuff on there, and feel safe. If that sounds more like what you’re hoping for, I suggest you get in touch with Mr. Austen to discuss this impressive solution. So, back to your external hard drive.
You placed your private data on it, and then you plugged it back into your computer a week later. Can you read the data? Sure you can. The hard drive is still an internal component of the chassis, which carries the built- in decryption chip.
So as long as that drive is inside that chassis, you can read and write the “encrypted” data just as if it were unencrypted. So exactly when does the encryption protect your data from prying eyes? Synaptics Multitouch Driver Windows 7 Download.
Why it should be obvious: when the internal hard drive is removed from the external chassis. When a thief steals your drive, are they going to sit down at your desk, pull out a Phillips screwdriver, and gently remove the internal hard drive from the chassis? Or are they going to grab the whole thing and run off with it, decryption chip and all? Similarly, if you lose the drive, will it still be readable by the finder? Sure, it will. So when does the encryption actually take effect? When the chassis fails. If your hard drive gets zapped from a surge, or otherwise the circuit board of the external unit gets damaged, data recovery “may not be possible,” says Phil Priest, a professional data recovery technician from PES Data Recovery in an interview with me this afternoon.
We can recover the hard drive’s data, but it would be entirely garbled and unusable without the proper key,”Data recovery may be possible in such a case. Priest goes on to say, “We had a recovery like that come in a while back. It was a Western Digital drive, and for some reason they had manufactured all the drives of the same model with the same decryption key.” He explained that the customer was fortunate in this case: the data was able to be recovered since a decryption key was readily available. However, the cost to procure the correct decryption key resulted in a notably higher cost of recovery and made expedited service impossible. Priest also warned, “if the manufacturer uses a different decryption key for each drive manufactured, there is likely no way to recover the data.”So who is the encryption on your external drive really protecting?
It would appear to me that the only person getting locked out of your data. Priest ended the conversation saying, “if your external hard drive has built- in encryption, make sure you keep a good backup.”To protect your company data from accidental data leak or intentional data theft, please take a look at Endpoint Protector.
