Kukisa – files which are stored on the PC of the user and comprise information on the websites, ever it visited. By means of kuk it is possible to learn about what pages were visited by the user.
Kukisa are files with information about ever the visited sites which are stored in the user's computer. I.e. when the user comes on some web resource, information on it registers in kukisa and at the subsequent visit of this website is transferred to the Web server.
For what are necessary
Kukisa contain various information, for example, passwords of accounts on the websites, color of a template, font size which the user made for the website, etc. The most striking example as it is possible to use kukisa for saving settings gives Google search engine. This machine gives an opportunity to configure the search delivery, it is about amount of results on the page, a format of the issued pages, an interface language and other settings.
As for passwords from accounts on the websites, each user noticed more than once that having once specified the login and the password on any web resource, at repeated authorization he did not do it any more since this information on the website automatically registered in kukisa. At repeated visit of a resource the data are sent to the Web server which will automatically recognize the user, exempting it from need to fill fields again. Kukisa can be useful also for maintaining statistics.
No threat for the computer of a kukisa can be posed. It is only the text data incapable to do it harm. By means of kuk it is impossible to delete, transfer or read out information from the user's PC, however to learn about what pages he visited, it is possible. Modern browsers already give to the user a choice opportunity: save cookies or not, but if he selects service of shutdown of saving kukis, he should be ready to problems in work with some websites.
Shortcomings of kukis
First, cookies not always have an opportunity to precisely identify the user. Secondly, the malefactor can steal them. As for the wrong recognition, use by the user of several browsers can be the reason for that. Each browser has the storage therefore kukisa identify not the user, and its browser and the PC and if it has several browsers, then there will be also several sets of kuk.
Zloumyshlennikov can involve constant exchange of a kukama between the browser of the user and the Web server, if network traffic is not ciphered, it is possible by means of special programs-snifferov to read cookies users. This problem can be solved by encryption of traffic and use of different protocols.
