Bases of maintenance of information security - Security software news and downloads

In this connection there was also a new problem to provide security of programs and the data of the user from not automated influence on the part of other users’ information system during transfer of the information on channels Communications. Last decade in a foreign press is given the big attention to questions of a security of the data in Information systems. It is more often in the exaggerated kind begun to be given the information on abusing in use of the COMPUTER, refined industrial espionage and fires on computing.

The centers and "susceptibility" of the COMPUTER to acts of sabotage. With one the sides, it caused the certain disinformation of users, and another - forced to spend significant means on realization of protective actions. In the market development have appeared, covering various aspects of maintenance of security information, and also the special software packages, realizing procedures of protection and the control of a data access. The contents and tasks protection of the information by foreign experts are interpreted as follows. While in service systems accrued and the process able information is enough vulnerable, subject both to destruction, and non-authorized to use, i.e. information leakage limited uses. The basic ways of information leakage limited uses they count plunder of data carriers and the documents received as a result of work of information systems; copying of the information on the COMPUTER; the non-authorized connection to the equipment and communication lines; interception of electromagnetic radiations in process of processing of the information. In the foreign literature it is resulted a plenty of the examples, allowing to judge gravity and importance of a problem of a information security in information systems. Proceeding from the analysis of possible ways of outflow information are developed special methods and means of protection information. We shall specify a number of the definitions used in foreign 1/2% by consideration of questions of protection of the information:
"Possession", "security", "protection". The term "possession" socially caused right of the person or the organization is defined to establish conditions, addressees and time at which can be the information is transferred to other persons or the organizations. This term it is connected to the term "security".
Set of the methods, allowing defining is meant the right of the user on the reference to system and stored in it to the data. In some foreign works this term is used only with reference to the information of limited use. For other applications the term "possession" is used. In systems shared, terminals having an advanced network, the basic complexity of a security will be that the potential infringer is the full subscriber of system.
Therefore the term "protection" is meant as a way of maintenance security. Protection of the information is usually reduced to a choice means of the control over performance of the programs having access to the information stored in system. Sometimes under the term "protection" the means limiting consequences are meant inadvertent mistakes in the software or rule its uses. Really, such accidents it is necessary to exclude, however it has practically a little the general with a task protection against deliberate infringements of information security. Such in the image, in narrower sense protection represents set of methods and the means, allowing operating access varied out programs to the stored information in system.
