Water, Sewage & Effluent July-August 2017 | Page 24

The Gariep Dam is the largest storage reservoir in South Africa. Taking water security to another level Water security doesn’t only mean availability, but also whether the multitude of treatment plants throughout the country are at risk of being cyber hacked … By Tunde Ogunkoya F ollowing on the wave of recent cyber hacks taking place around the globe, Tunde Ogunkoya, consulting partner at Africa DeltaGRiC Consulting, discusses the possibility of utilities being cyber hacked. I did a presentation at the CyberXchange Conference last year, which somewhat addressed the question of utility security, though slanted towards the oil and gas industry. We narrowed down how certain vulnerability in a SAP application commonly used by that industry — and any large utility — could be used to siphon money and perhaps, as in the extreme case with 22 oil and gas (O&G), fund terrorism in oil- rich Nigeria. While there are many ways that a utility company (water, electricity, or O&G) may be hacked based on the applications that they use for automating their processes, I must disclaim that the water treatment process is not within my field of expertise, as our firm is a purely applications security firm focusing on SAP, Oracle PeopleSoft, and open- source software security. That said, cyber security has very little to do with business processes — <20% link to business processes. I will approach the topic from a purely Water Sewage & Effluent July/August 2017 application security perspective, and maybe touch on the operational technology part of security in the utilities industry: SCADA, PLC- Programme Logical Control, and Distributed Control Systems. The risk and motivation for hacking that we see in the utilities industry is mainly sabotage risk from an external attack perspective, and fraud risk from an internal attack perspective. There could be many other places by which a hacker can access a water treatment technology landscape, be it networks and/or operational technology (OT). By simply searching for ‘water’ on Shodan (the world’s first search
