Simoco CEO warns for vulnerability of legacy SCADA systems


In a Blog article, Mike Norfield (Group CEO at TTG) explains how legacy communication technologies are leaving critical infrastructure at risk. Especially with the Wannacry ransomware attack, which swept across the world in May this year and another attack earlier in 2015, were a cyber-attacker successfully seized control of the Prykarpattyaoblenergo Control Center (PCC) in Western Ukraine, leaving 230,000 without power for up to six hours, it looks like many of these attacks are linked to the PCC’s legacy SCADA system. The attackers overwrote firmware on critical devices at 16 substations, leaving them unresponsive to any remote commands. According to Norfield, legacy systems of any kind ultimately contain vulnerabilities that cybercriminals can take advantage of while having multiple disparate technologies can also make it very difficult for organisations to have a ‘single pane of glass’ view of what is happening across a communications network. In turn, when a problem does occur, it can be tricky to identify, isolate and remediate.

The answer according to the CEO is Unification. He says: "Utilities organisations need to unify all of their disparate communications hardware and software on a single communications network. Complex and divergent communications technologies need to be brought together on unified architectures, with all voice and data managed from the same centralised platform. This doesn’t need to lock utilities companies into single manufacturers or proprietary technologies – on the contrary, serial, Ethernet and PMR radio as well as mesh and LTE technologies can all be integrated together. The key point is to bring unification where there have previously been vulnerable legacy systems and disparate, unconnected technologies".
