Abstract

Security is the main issue to address when an organization wants to connect their private network to the Internet. Without taking into account the type of business, the number of users of private networks is increased by the demand for access to Internet services, such as the World Wide Web (WWW), Internet Mail (e-mail ), Telnet, and File Transfer Protocol (FTP) Network administrators have to increase the security mechanisms of their systems, because they expose the private data of the organization as well as the infrastructure of their networks to the Internet. In order to provide the required level of protection, an organization needs to follow a security policy to prevent unauthorized access by external users to the private network's own resources, and to protect against the export of information, as well as to establish an internal security policy To manage user access to network segments and protect secret information. Due to the large and diverse type of information and the level of exposure that is handled in a company it is necessary, among other things, to segment the network, with different levels of security for each segment, thus ensuring the integrity of the information of each One of the services, as well as the control and access.
