Computers in

Dnipropetrovsk

   Computers and networks in our time are utillized almost everywhere. Reservation almost we left for those remote corners sew on planets where yet "stone age" and tailings of "feudal line-up" prospers in area of information technologies and computer literacy, and to that parallel instances, where about computers, certainly, heard, but did not see alive, or it is been afraid of them in general. Strangely enough, these computers and networks break from them. Clearly, that by not hammers, such cases are though and. And not pioners, I.e. dullish and illiterate, but very active amateurs which add itself on the category of "Advanced user", speech will go later about them, in the next article, and the most real hackers, I.e. high quality specialists in an environment network and computer of safety, programmers high level.

More frequent than all it does not turn out for them, as above breaking of networks, servers, sites, or simply banal user computers high quality hackers work. Asks: why are they engaged in this? Frequently by reason there is a very banal desire to prove it, attempt to be delivered from the complex of inferiority - to confirm hackers in a company "Wicked and insidious", increase the trade in this area, desire to utillize the resources of networks in the aims, punish bad, to encourage good, or simply for a money. Without depending on motive reasons such actions are criminally punishable, in obedience to the legislation of country, in the area of jurisdiction of which there is this action, and also pursued international organizations, supervisory violation of intellectual ownership rights. (prim. avt.)  

Who is more frequent than all broken up by hackers?
1. Providers - for the receipt of the free Internet,
2. Shallow commercial companies - on them usually and there is teaching hacker trade,
3. Banks - for the receipt of the real income. But it is frequently impossible to do it physically, and probability subsequent after breaking of taking of housebreaker for a pillion very great :),
4. Pornosites - for entertainment.
Housebreakers often utillize the skaners-programs for determination of machines which can be broken up, and then they are broken. Also the task of breaking of concrete object can be given hackers: in this case business, as a rule, is related to the large money. Before the beginning of work, a hacker collects all of information about an object (and not only through a network).
Usually in companies it put web-server, will honour, etc. (We will consider in future, that there is the real in a firm, high-professional sysadmin, recipient a very decent pay-envelope (from $1000), but not some clever man, counting itself by God. Breaking is far facilitated in this case, or in general passes unnoticed. Such clever men, by the way, now very much) A web-server in most cases reposes on a separate computer, and other computers in a local network are dissociated from the world of FireWall, which is put on a sluice-router is needed in an order to prevent breaking both outside and from within. We will consider in future, that a hacker needs to get access to the network. Web-servers not broken up usually, if, certainly, filtration of packages and addresses (NAT) is correct, and a purpose of breaking is a web-representative office of firm not exactly.

Mail server where more interesting from point of content of information and tekhnologiii breaking, as mail must spread outside a local network and go out some sly appearance in space of the Internet. If the purpose of breaking was a booty of valuable information, this purpose is practically attained, as breaking up a postal server, a hacker did the half of work, and scarcely subsequent defence will appear better, than already broken up. Nevertheless, works yet carriage: to collect passwords, rock info from the broken (infected) up machines and others like that. Breaking is thus carried out approximately, approximately the same way for you steal documents, approximately the same way you find new head pain. With recommendations and comments we will consider further development of events  in the next article.
