SCADA (Supervisory Control And Data Acquisition) networks control much of the industrialised nations production and supply complexes. Various government reports and investigations have highlighted the vulnerability of these systems. Many of these systems are on private networks which are increasingly being connected to systems that are accessible from other networks such as the Internet. There are a range of open source tools that now offer fonctionality that can be used to secure SCADA networks from intrusion or compromise. This paper explores some of the issues with current SCADA deployment trends from a network security perspective and then examines open source countermeasures that could be used to help mitigate some of these risks.
