One of the problems of modern data transmission on the Internet, associated with the growth of users of network resources and increasing demands on the capabilities of IP-networks, is to ensure secure data transmission. In this regard, the monograph analyzes the advantages and disadvantages of modern means and methods of security IP network, built a simulation model of IP network based on software Asterisk and to determine its security parameters is the study of modern methods of cryptographic protection. For the study software Cryptool 2, Opnet Modeller 17.5, Python are used. The fact that every year computer technology improves, and new threats and vulnerabilities appear faster than methods of their protection led to the development of a new direction in network security – steganography, which allows you to hide the fact of transmission of information. Particularly urgent problem of information protection is in networks, organized for small and medium-sized businesses, as the question of profit from production is often higher than ensuring the safe operation of the enterprise network. In the monograph the model of concealment of information with the help of LSB is presented and the method of four-level protection of data transmitted over IP networks is considered.
