ABSTRACT
In 1975, the Defense Advanced Research Projects agency (DARPA), which originated as the ARPA, started to develop the TCP/IP protocol stack. In 1979, a committee was formed to lead the development of these protocols. The Internet is an articulated set of computer networks, which uses the TCP/IP protocol to packet communication, and contains many servers that generally operate with operating systems UNIX and Linux. The simple network management protocol is the most expressive standard in terms of network management. It is a protocol that is used to deal with eventual network or equipment failures. The public and open nature, without protection mechanisms, made security is one of the main structural problems of the TCP/IP architecture. This opening was responsible for the success and popularization of. However, the deficiency in the security aspect represents one of the limitations to the use of technology, especially in commercial applications.
