| Resumo: | The utilization of firewalls is a widely accepted approach when protecting Automation
Technology (AT) environments from Information Technology (IT) ones. This dissertation
covers the development of a firewall system for TCP/IP-based industrial networks which
can protect automation devices from abnormal traffic. Thus, all non-conformity traffic or
traffic which does not respect the imposed constraints is considered abnormal and must
be blocked. It was developed an user-space application which filters traffic in the application
layer. The industrial protocol chosen as a case study was Modbus/TCP, due to its
simplicity, abundant documentation and high relevance for current industrial networks. |
