This paper shows how advances in the development of information and communication technology and the increasing use of publicly available networks, the Internet, have influenced the creation of electronic business. The work emphasized the importance of information as a key business resource within e-business, which contributes to better quality business decisions and gaining insight into consumer habits and behavior. That is why it is no surprise that the need to collect large amounts of data is also increasing. The issue of privacy and security of data and information has been emphasized throughout the electronic business and the importance of information security protection. Legislative, organizational and technical protection is outlined in the paper, and the statistical data has shown that concern about information security is still present. This raises the question of whether full information security is possible?
