Digital transformation was a key process for companies in the oil and gas industry. Thanks to innovation, they became more efficient, productive, reliable and sustainable. But it also opened up the ground for cyber-attacks.
With operations depending on digital technologies, many of which rely on OT network infrastructures (operational technologies), cybersecurity in Oil & Gas is becoming increasingly important.
This is determined, for example, by a study by GlobalData, which states that investments in the oil & gas business to protect its data, applications and users will reach US$10 billion by 2025.

Cybersecurity challenges in Oil & Gas
In many ways, cybersecurity requirements in Oil & Gas are no different from those in other industries. For example, in the need to respect data privacy and ensure business continuity.
But there are some specific characteristics of this sector that make it particularly challenging. Below we will detail some of the most important ones.
Infrastructure vulnerabilities
Refineries, pipelines, drilling platforms. The OT infrastructure (operational technologies) of Oil & Gas companies usually presents multiple points of attack. Often, even the technologies involved are outdated or, due to their criticality, have few updates in order not to stop the plant’s production.
At the same time, the integration to IT (Information Technology) or IoT (Internet of Things) networks opens new gaps to contemplate and protect, due to the interconnection generated between the different networks. A cyber-attack on one of these facilities can paralyze the operation, generating high financial, reputational and even environmental and security costs. Therefore, ensuring their security is a priority for the business.
Threats to operational data integrity
Operational data are at the heart of the business in the Oil & Gas industry. It is the key to ensuring operational efficiency and safety. Especially nowadays, when more and more companies in the industry are adopting data driven models. Any alteration, destruction or theft of this data can cause serious consequences that can have a major impact on the organization’s results. For example, incorrect decisions can be made regarding production or personnel care.
Disruption risks in the energy supply chain
The energy supply chain spans from the extraction to the distribution of oil and gas. It is an extensive process, spanning multiple sectors and even multiple organizations, and is remarkably complex. The repercussions if disrupted following a cyber-attack do not just impact the company. It can have global consequences across industries, households and transportation. They can even affect national security and the stability of international energy markets. That’s why a cybersecurity strategy focused on management and control systems is essential. To guarantee the production, transfer and distribution of energy.
Cybersecurity best practices in Oil & Gas
Considering both general and specific challenges, and based on accumulated experience, we identified a couple of best practices.
Regular system and software updates
Security patches and regular updates fix known vulnerabilities. They also improve the resilience of systems against new threats. That’s why patch management policies should be very strict. At the same time, it is essential that systems are kept up to date. This applies to both OT (operational technologies) and IT (information technologies).
Control of the connection between networks
It must be clear how the connection and segmentation between the different networks (IT, IOT and OT) is defined in order to detect vulnerable points and have control over the traffic that can enter the different devices in the system. It is therefore important to identify which devices are connected, what type of connection exists between them and what type of vulnerabilities they may present. With this, a clearer picture of the scenario is obtained to improve security in a more controlled way.
Efficient data backup and recovery
The number of cyberattacks is growing in volume and sophistication. Therefore, it is not only about prevention, but also about having strategies in place to minimize the impact in case it happens. Regular and automated backups ensure that data can be recovered quickly in the event of loss or alteration. Recovery plans should be regularly validated to verify that they are meeting their objective. That is, to restore operations as quickly and as cost-effectively as possible.
