The nature of the data. All information is stored on your computer, can be divided into two categories: — data. Applications — are tools for work, and data — is something to that affect applications. Data — certainly the most valuable. Of course, and application software is also needed, but in reality valuable algorithms that they use, and not the applications themselves. Most users and technical experts agree: the data — this is the most important. Whether the government, the banking industry, telecommunications, healthcare organizations, control of production or transportation services using electronic data — a vital foundation of the world economy. — Outwardly directed. Inside aimed data — information, often proprietary company itself, necessary for the production of goods and services. This data is used by members and various business divisions of the company. These data should not leave the limits of the organization. Outwardly directed data — information used by the company to compete in the market. Such as they are called «portable» or «mobile» data can be used in sales, customer service and analytical functions. Data stored on a laptop computer seller — outwardly directed data. These data are more at risk than internal efforts. This distinction is particularly important to understand the experts on their safety, as statistics information security breaches in recent years testifies to the fact that many of them do not fully realize the importance and differences between the protection of internal and external data. Data protection and data directly themselves have a huge impact on the functionality of business and profits. Therefore, a specialist in data security should focus on protection, both external data and internal. Further problems occur when the security professionals are fixated on providing information security, but do not take into account the conditions of rapid access and comfortable working with data. This leads to a decrease in the efficiency of the company. Full disk encryption. If you ask a specialist in IT (information technology), how to protect «portable» information, such as a laptop, it will most likely advise you to complete encryption system. At first glance it seems an easy task. In fact, it is not. Full disk encryption requires that the number of keys that were distributed in an encrypted system, so that the major software applications were not encrypted and could work. Since in this case the encryption keys are located together with the encrypted information, it creates additional opportunities for breaking the data. It is unlikely that someone will be able to pick up the code to the encrypted information, but the chances grow up, if the code is encrypted with information and is protected by only four digits. Several shortcomings. Encryption is often used applications — is to reduce the system efficiency and unnecessary steps. At full encryption system recovery tools also encrypted. If full encryption system suffers a bug, or are damaged keys, you can tell the system, farewell, she goes down and the chance to rebuild its conventional means will not, because in this case, the recovery mechanism will also be encrypted. Then it will be difficult to return the system to working condition, just as and restore data. Encryption system prevents theft of data. Recruitment of staff and consultants meant by a certain level of confidence. Confidence in the security implies access. In order that the officer doing his job, he must have access to unencrypted information. Therefore unable to protect encrypted data when they are in use. All efforts should be directed encryption to protect data access and copy protection data. Proximity data. Using the method of proximity data are encrypted on each system, where they remain. Once the data packet is copied to access it, you can only connect to the enterprise. To decrypt the data required a key that is stored within the system of organizations. Accommodation and storage of encryption keys within the corporate infrastructure adds additional protection, as this is a risk that they will fall into the wrong hands, reduced. The proximity of the data developed as a light information solutions, providing data protection, and at the same time without affecting the efficiency of the system. Conclusion. — Residential dump defined by the user. — All keys are stored in a certain place, and there is no need to store them on a mobile system — the system can be downloaded at any time, because the operating system is not encrypted — control external connected device and its use (flash drives, CD-ROMs, external Hard drives, etc.).
