Guarding the gates: a look at critical infrastructure security in 2023

With 2022 now in our rearview mirror, we still reflect on a time marked by global upheavals, like the Russia – Ukraine war,  to the skyrocketing energy prices and global inflation. The impact of these disruptions reverberated worldwide, reaching beyond just our economy. These global events have also underscored the crucial significance of safeguarding our critical infrastructure against domestic or foreign attacks.

As the end of 2023 approaches, it becomes imperative to assess the current landscape of cybersecurity threats, explore potential strategies to combat them, and explore the new practice measures that can be taken.

This analysis isn’t just a statistical exercise but a crucial necessity in our interconnected world, where the security of our digital infrastructure is intertwined with our physical safety and economic stability.

Navigating the complexities of the modern cybersecurity landscape

In this digital age, the field of cybersecurity is becoming increasingly intricate and challenging. Our interconnected online world is no longer separate from our lives, businesses, or our global economy. As a result, cyber threats have the power to cause real-world effects that spread across industries and sectors leaving a lasting impact on a major level.

It’s easy to envision the outcomes that could arise from a major assault on our vital infrastructure. This underscores the pressing importance for security researchers and cybersecurity professionals to work together to evaluate risks, devise defenses and team up with governments and corporations to safeguard our resources.

Thankfully, as new dangers arise, we also see the emergence of groundbreaking technologies that can help us combat them. While these technologies aren’t complete fixes to the problem, they do offer an extra layer of security to protect our vital infrastructure.

Modern advancements like artificial intelligence (AI) machine learning and blockchain-based networks specifically have an impact in this area. By leveraging these tools, organizations can utilize multiple technologies like Active Directory alongside Privileged Access Management (PAM) solutions to build layered corporate defense and more accurately detect threats and respond quickly which leads to improved security performance.

Uncovering the domestic and foreign threats to critical infrastructure

Critical infrastructure refers to the physical and virtual systems and assets so vital to our society that their incapacity or destruction would have a debilitating impact on security, national economic stability, public health, or safety. As technology advances, so too does the sophistication of threats to these essential systems.

Ransomware Attacks: Ransomware attacks pose a substantial threat to critical infrastructure. These attacks employ malicious software that encrypts files, rendering them inaccessible until a ransom is paid or a backup is restored.

Cybercriminals specifically target sectors such as healthcare, energy, and transportation, recognizing the significant consequences at stake. Organizations in these sectors cannot afford prolonged downtime, which then increases the likelihood of succumbing to the ransom demands.

Financial Institution Attacks: Financial institutions are highly susceptible to cyber threats due to their large amounts of highly sensitive data. Money laundering, social engineering scams, and identity theft are all examples of attacks that can be used against financial institutions. Making matters worse, these attacks often go undetected when organizations fail to properly monitor their systems.

Botnet Attacks: Botnets, networks of compromised computers controlled by an attacker, pose another substantial threat to critical infrastructure. These networks can be used to carry out Distributed Denial of Service (DDoS) attacks, overwhelming a system’s resources and causing service disruptions. In addition, botnets can be used for data theft, spam distribution, and ransomware dissemination.

Depending on the level of security needed, facilities might opt for high-security fencing options, such as anti-climb or electrified fences.

Enabling Privileged Access Management: Privileged Access Management (PAM) is critical to any strong cybersecurity strategy. It involves managing and monitoring access to critical systems and data, ensuring that only authorized individuals can access the resources needed to perform their roles.

PAM can help prevent insider threat risks and reduce the potential of credentials becoming compromised. Furthermore, it provides a clear audit trail, which can be invaluable in investigating security incidents.

Deploying Network Monitoring: While physical security measures are vital, we cannot overlook the importance of securing our digital infrastructure. Deploying network monitoring tools can provide real-time visibility into the network’s activities. These tools can detect unusual patterns or behaviors that could signify a cyber attack, such as sudden spikes in network traffic or unauthorized access attempts.

Moreover, network monitoring tools can help identify vulnerabilities within the system, allowing IT teams to address these weak points before they can be exploited. Regular network monitoring combined with timely updates and patches forms a significant part of maintaining a robust cybersecurity posture.

And as more teams go remote, this increases risk to a company’s network, so utilizing solutions like Privileged Access Management (PAM) to harden Remote Access Protocols (RDP) is essential. Regular network monitoring combined with timely updates and patches forms a significant part of maintaining a robust cybersecurity posture.

Creating a Robust Business Continuity Plan: A business continuity plan (BCP) is a proactive planning process that ensures critical services or products are delivered during a disruption. A BCP typically includes four steps: business impact analysis, recovery strategies, plan development, and testing and exercises.

In the context of national and state security, a robust BCP ensures that essential functions continue operating during a crisis, whether a natural disaster, a cyber attack, or any other disruptive event. It also outlines how to get back to ‘business as usual’ quickly after a disruption.

Having a well-documented and regularly updated BCP can significantly enhance resilience and reduce the impact of disruptions on operations and services.

Introducing a Comprehensive Employee Cybersecurity Training Program: Employees often represent a significant vulnerability in an organization’s cybersecurity posture. Without proper training, they can fall victim to phishing attacks, inadvertently download malware, or mishandle sensitive data.

Introducing a comprehensive employee cybersecurity training program can significantly reduce these risks. Such a program should cover many topics, including recognizing and avoiding phishing emails, using strong passwords, securing devices, and understanding the importance of regular software updates.

But a truly effective program goes beyond just imparting knowledge—it also fosters a culture of security where employees understand their role in protecting the organization’s data and systems. Regular training sessions, combined with ongoing reinforcement and practical exercises, can help embed security awareness into the everyday behaviors of employees.
