Threats of information safety

At change of a way of storage of the information from a paper kind on digital, the main question has appeared - as this information to protect, in fact very much a plenty of factors influences safety of the confidential data. To organize a safe data storage, first of all it is necessary to lead{carry out} the analysis of threats, for correct designing of circuits of information safety.

Threats of information safety share on two basic types are natural and artificial threats. We shall stop on natural threats and we shall try to allocate the basic from them. Fires concern to natural threats, flooding, hurricanes, impacts of lightnings both other acts of nature and the phenomena which do not depend on the person. The most often among these threats are fires. For good safety the information, a necessary condition is the equipment of premises{rooms}, in which there are elements of system (carriers of figures, servers, archives and so forth), fire-prevention gauges, purpose{appointment} responsible{crucial} for fire-prevention safety and presence of fire extinguishing means. Observance of all these rules will allow to reduce to a minimum threat of loss of the information from a fire.

If premises{rooms} with carriers of the valuable information settle down in immediate proximity from reservoirs they are subject to threat of loss of the information owing to flooding. The only thing that can be undertaken in the given situation is to exclude storage of data carriers on ground floors of a building which are subject to flooding.

One more natural threat are lightnings. Very much often at impacts of a lightning network maps, electric substations and other devices fail. Especially appreciable losses, at an output{exit} of the network equipment out of operation, bear{carry} the large organizations and the enterprises, such as banks. In order to prevent similar problems it were necessary connecting network kabeli are shielded (the shielded network cable is steady against electromagnetic handicapes), and the screen of a cable should be earthed. For prevention of hit of a lightning in electric substations, it is necessary to establish an earthed lightning rod, and computers and servers to complete with sources of a uninterrupted feed{meal}.

And so, we have disassembled natural threats of information safety. The following kind of threats are artificial threats which in turn, share on inadvertent and deliberate threats. Inadvertent threats are actions which are made with people on imprudence, to ignorance, a carelessness or with curiosity. To such type of threats carry installation of software products which are not included into the list necessary for job, and in a consequence can become the reason of astable job of system and loss of the information. Here it is possible to attribute{relate} and other "experiments" which were not malicious intention, and people making them, did not realize consequences. Unfortunately, this kind of threats very difficultly gives in to the control, besides, that the personnel has been qualified, it is necessary that each person realized risk which arises at his  non-authorized actions.

The deliberate threats - threats connected with malice aforethought of deliberate physical destruction, subsequently failure of system. Internal and external attacks concern to deliberate threats. Contrary to a popular belief, the large companies sustain mullions-strong losses frequently not from hacker's attacks, and on fault of own employees. The modern history knows weight of examples of deliberate internal threats of the information are tricks of the competing organizations which introduce or hire agents for the subsequent disorganization of the competitor, revenge of employees which are dissatisfied with a wages or the status in firm and other. That the risk of such cases was minimal, it is necessary, that each employee of the organization corresponded{met}, so-called, to " the status of reliability ».

It is possible to attribute{relate} threats of hacker's attacks to external deliberate threats. If the information system is connected to a wide-area network the Internet for prevention of hacker's attacks it is necessary to use the gateway screen (so-called firewall) which can be, both is built - in the equipment, and realized programmno.

If to observe all safety measures from threats which are listed above your information will be reliably protected.
