The world is getting closer to becoming an information society. The information society is a new and more perfect form of social organization in which a network based on highly developed information technology, equal and free access to information, appropriate content (content) in accessible formats and effective communication should help all people to fully realize their potential, promote sustainable economic and social development, improving the quality of life, reduce poverty and eliminate hunger. In some countries most of the benefits of the information society has become a reality today. First of all, the countries of Western Europe, USA, Japan, but this list is not exhaustive. Information technology makes our life easier and widespread. A lot of them all around us: field of study or work, at home. The laptop and the device are constant companions of a successful business man. And today it is not necessary to spend a lot of time to waste on routine tasks that can be automated, in search of some good shops in the city, you can visit the websites of various online stores, and choose and order there, and very often with more choice and at a lower price than a regular store.
Very large scale and has found Internet business. Many companies use web hosting to create your Internet resources and to attract new customers.
Local computer networks, some of which cover their covering entire cities, and global, among them all home the Internet gives you plenty of opportunities — a quick search of the necessary information, distance learning in schools, acquaintance with the news from around the world, communicating via email and in real time, so scientists today are not surprised by the invitation to take part in a video conference with participants from different cities, countries or continents. Of course, video conferencing deprived of all the opportunities offered by live chat, but still very useful.
Regarding the people involved in the development of information systems and software is already established schemes, under which a significant portion of programmers can work remotely, and coordinating the implementation of projects is carried out in a specific administrative centre of the organization, which is engaged in the development. And such schemes are used in other industries. It enables a person not to relocate, work in a team and thereby makes it more flexible according to the conditions of life in modern society.

A simple example: you can decrypt the data sent by e-mail, to forge a signature, etc.. Certainly, the protection needs not only correspondence and information conditions. Any important information must be protected against intentional or accidental interference. It concerns the protection of information and software products, which involves the use of programs that are activated not by purchase, as a result of illegal actions.

So, the attacker can obtain or calculate the password of the person who has administrative rights or is the head of a particular unit and, after logging in with his username and password, may obtain access to classified
information, and in the first case, even destroy the information base and to bring down the system.
Impossible to do without information security in e-Commerce systems. People must be sure that the money in his account will be safe after making a purchase, that is, an attacker will not be able to access his money using the information entered in the electronic forms.
As you can see, computer technology to solve important problems of people, provide them with the tools that can automate the decision of knitting a large number of tasks, solve the problem of communication, save much time, promote team work of developers and scientists, and a variety of project activities. Also very valuable intellectual systems of decision support.
