Cybersecurity in the Energy Industry
Secure the increasingly networked energy industry from cyber threats.What is cybersecurity in the energy industry?
Without a secure and resilient energy system, entire industries would grind to a halt. Energy cybersecurity services from a trusted third-party such as TÜV SÜD can help make your energy infrastructure more secure.
In recent years, several trends have made it even more critical to establish strong security policies in the energy industry.
Digitalisation, automation, and technologies such as 5G and the internet of things (IoT) are enabling unprecedented optimisations in the sector. However, these are also presenting new opportunities for attacks and disruptions. Smart grids and IoT-powered devices at home increase energy systems’ interconnectedness and render the components more vulnerable to cyber threats.
The push towards sustainable energy also calls for a more decentralised and networked electricity system, broadening the attack surface. Market reforms likewise allow new actors – from energy companies to energy communities and citizens – to participate in the industry. Many will not have adequate cybersecurity skills. Market forces do not adequately incentivise energy players to make security investments, which means that regulation and the public sector may need to pick up the slack.
All these pose additional challenges for electricity-dependent operators of essential services (OES) and critical infrastructures, who are already under pressure to guarantee cybersecurity.
Why energy cybersecurity is important
The consequences of disruptions to your energy infrastructure are far-reaching. The security standards applied to typical information technology (IT) systems may not be sufficient for your energy systems’ specific needs. Cybersecurity for energy requires a comprehensive approach that addresses a few key considerations.
Energy grids today typically use a mix of legacy and modern components. Old components remain in use long after newer ones are deployed. This calls for complex security measures – Newer devices may be governed by cybersecurity certifications, but older ones will need to be protected differently.
Energy grids also demand real-time response – Industrial control systems must react within seconds to balance supply and demand at any given moment. This means that sophisticated yet lengthy authentication procedures may not be suitable for energy systems.
Disruptions in energy systems could have massive cascading effects. The interconnectedness of power grids means a serious disruption in one part of the system could spread to other grids, which could then lead to blackouts over wide areas. Electricity-dependent essential services – such as water supply, transportation, telecommunications, and finance – will be affected. Breaches can also damage your reputation and result in expensive penalties.
In light of all the above, regulations have emerged all over the world. These regulatory requirements vary across the globe. Some mandate the preparation of advanced business continuity plans, the appointment of a Security Liaison Officer to coordinate with national authorities, and the certification of products, services, and processes.
A comprehensive approach to energy cybersecurity is necessary to secure your systems. Your organisation needs to boost cybersecurity awareness and develop the necessary information technology (IT) skillset. You need to be proactive by incorporating security and resilience into all your products and services, keeping it top of mind from day one of product development.
Furthermore, ensuring robust IT security and up-to-date IT infrastructure will reduce the likelihood of disruptions. Real-time, instantaneous visibility and control of your systems is vital to ensure that disruptions do not create ripple effects throughout your grid. You should also ensure that your entire supply chain, including second and third-tier suppliers, strengthen their defences.
