Security measures for energy production plants were formerly focused on the physical security of the plant, including considerations for the perimeter and reliable procedures. Years ago, cybersecurity was not considered so vital because energy production plants were based on SCADA systems that were closed off and ran on proprietary protocols. But are these systems still safe today?

The Stuxnet worm demonstrated in 2010 that even if a system is protected and cannot be accessed by external attackers, it can be hacked. This type of attachment at the programmable logic controller of the SCADA cannot likely be replicated for this peculiar case, though everyone remembers this event as a milestone. After 2010, the entire world was made aware that SCADA systems can be attacked and, thus, must be protected.

On the other hand, is it really true that SCADA systems are so closed that they cannot be accessed by external forces? The reality is that SCADA systems originally used proprietary interfaces that were not always very user-friendly. In order to improve the user experience, SCADA systems are now often interfaced with a standard user’s interface. Also, in order to reduce the costs of management, standard marketplace protocols are used. Therefore, SCADA systems may be closed, but they are based on elements that can be affected by cybercrime.

Grid introduction in the production of energy and the usage of digital metering systems for an intelligent utilization of the energy implies that the production plant cannot be included within a perimeter.

Industrial processes are now strongly based on IT. To create a problem for an enterprise focused on producing energy, it is not necessary to compromise the SCADA systems, but it could be enough to attack the customer relationship management system. In fact, how many days could an enterprise survive without receiving money from clients or without paying providers and employees?

Therefore, protecting an energy production plant is strongly connected to cybersecurity. There needs to be a holistic approach to protecting the enterprise. Rather than just focusing on protecting the infrastructure, data or application, all elements necessary to provide service should be protected.

Bridging the 3.4 Million Workforce Gap in Cybersecurity

As new cybersecurity threats continue to loom, the industry is running short of workers to face them. The 2022 (ISC)2 Cybersecurity Workforce Study identified a 3.4 million worldwide cybersecurity worker gap; the total existing workforce is estimated at 4.7 million. Yet despite adding workers this past year, that gap continued to widen.Nearly 12,000 participants in that study felt that additional staff would have a hugely positive impact on their ability to perform their duties. More hires would boost proper risk…

CEO, CIO or CFO: Who Should Your CISO Report To?

As we move deeper into a digitally dependent future, the growing concern of data breaches and other cyber threats has led to the rise of the Chief Information Security Officer (CISO). This position is essential in almost every company that relies on digital information. They are responsible for developing and implementing strategies to harden the organization's defenses against cyberattacks. However, while many organizations don't question the value of a CISO, there should be more debate over who this important role…

Everyone Wants to Build a Cyber Range: Should You?

In the last few years, IBM X-Force has seen an unprecedented increase in requests to build cyber ranges. By cyber ranges, we mean facilities or online spaces that enable team training and exercises of cyberattack responses. Companies understand the need to drill their plans based on real-world conditions and using real tools, attacks and procedures. What’s driving this increased demand? The increase in remote and hybrid work models emerging from the COVID-19 pandemic has elevated the priority to collaborate and…

Why Quantum Computing Capabilities Are Creating Security Vulnerabilities Today

Quantum computing capabilities are already impacting your organization. While data encryption and operational disruption have long troubled Chief Information Security Officers (CISOs), the threat posed by emerging quantum computing capabilities is far more profound and immediate. Indeed, quantum computing poses an existential risk to the classical encryption protocols that enable virtually all digital transactions. Over the next several years, widespread data encryption mechanisms, such as public-key cryptography (PKC), could become vulnerable. Any classically encrypted communication could be wiretapped and is…
