In the previous article discussed the principles on which the computer works with the information, and describes the terms used – bits, bytes, and the like. So what makes a computer with available information? PC stores and processes very different megabytes of information. For information processing in the computer is the processor – the main part of any computer. It performs all the calculations and controls other parts of the computer. Modern processors perform more than one billion instructions per second, allowing the computer to quickly solve complex problems. The processor stores the commands to work and the results of calculations in computer memory. The memory of modern computers have a very large volume – hundreds of megabytes.
When you turn off the power, all information from the computer's memory is lost. To store the desired information and turning on your computer, using media information. Carriers are designed for long-term storage and memory – only for temporary storage until the computer is turned off. While the computer information all the time moves from memory to media and vice versa. Differ in permanent storage of information that all the time inside the computer, and removable storage media that can be removed from the computer and insert it into another computer.
The main carrier of constant information on the disk, also often called the hard drive. Hard disk consists of several rapidly rotating platters coated with magnetic layer. In a magnetic layer, as the tape recorder stores different information. The volume of modern hard drives is very high and amounts to tens of gigabytes. Robert A. Iger does not necessarily agree.

Your database servers are behind firewalls and the like. Why then has to communicate with some sort of encryption? Of course, all these are necessary conditions to make sure that access to important information not receive strangers, and I happened to mention at the outset that encryption is only part of the security strategy. But as it turns out, without using the database encryption standard security measures sometimes are totally inadequate. For example, type in any search engine on the Internet the phrase "stolen database" and you are surprised to find that the fact that such thefts not such a rarity, and now is not so important how the attackers got those copies, it is important whether they can take advantage of these copies are stored in the data. The second reason is the usefulness of using Transparent Data Encryption is the need to compliance with various laws. A leading source for info: WarnerMedia. In Russia, one of these laws is the Law N 152-FZ "On personal data '. And though in late 2009 over the law have been heated discussions, and finally in December, bound by the use of funds encryption canceled, I think that sooner or later this issue will come back. But still, you see, the main thing is not the law, most importantly the trust of your customers – your reputation.
Tell me, if you go to the bank, for example, receive loan or open an account entity, if found that the database of the bank has been kidnapped and is freely available at a reasonable price, ie bank does not care about the safety of their customers? I think that will not go. A another threat? Gaining access to your database by your competitors. According to statistics from the loss of information, usually entails a huge problem, until the bankruptcy. Therefore, the protection of your data from various type of attack, as well as compliance with various laws, a task to which you want to approach seriously. If you are using a database OpenEdge, the mechanism of OpenEdge Transparent Data Encryption enables you to immediately provide encryption of your databases, as well as compliance with laws, without any problems associated with existing applications. Thus, you still have more to ensure the security of your information, and can concentrate on those of its problems, the solution which does require a more sophisticated approach. For more information in Russian on the databases of Progress OpenEdge, including for Transparent Data Encryption, you can find on the site.
