Uma ferramenta de manipulação de pacotes para análise de protocolos de redes industriais baseados em TCP/IP. 2009. 59 f. Dissertação (Mestrado em Automação e Sistemas; Engenharia de Computação; Telecomunicações) - Universidade Federal do Rio Grande do Norte, Natal, 2009.https://repositorio.ufrn.br/jspui/handle/123456789/15292This work presents a packet manipulation tool developed to realize tests in industrial devices that implements TCP/IP-based communication protocols. The tool was developed in Python programming language, as a Scapy extension. This tool, named IndPM- Industrial Packet Manipulator, can realize vulnerability tests in devices of industrial networks, industrial protocol compliance tests, receive server replies and utilize the Python interpreter to build tests. The Modbus/TCP protocol was implemented as proof-of-concept. The DNP3 over TCP protocol was also implemented but tests could not be realized because of the lack of resources. The IndPM results with Modbus/TCP protocol show some implementation faults in a Programmable Logic Controller communication module frequently utilized in automation companiesapplication/pdfAcesso AbertoSegurança em redes industriaisSegurança em infraestrutura crítica, Testes de conformidade de protocolos industriaisModbus/TCPDNP3 sobre TCPIndustrial network securityCritical infrastructure securityIndustrial protocols compliance testsModbus/TCPDNP3 over TCPmasterThesisCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA
