Critical Infrastructure Resilience: Lessons from Recent Regional Cyber Incidents

When power grids, water supplies, or healthcare networks are disrupted, they stop working, which brings daily life to a standstill. Regional cyberattacks in recent years have already resulted in the shutdown of such vital infrastructures in local networks and several states. At the same time, such cyber incidents make it clear that public safety and even national security hinge on digital security.

It is therefore vital that authorities prioritize critical infrastructure cybersecurity to ensure cyber resilience, which allows organizations to respond to disruptions and restore processes with minimal downtime.

Lessons Learned from Recent Cyberincidents

Recent cyberattacks on regional utility companies and local government have demonstrated several weak points that, if adequately addressed, would prevent such incidents in the future.

Legacy Systems Are Vulnerable

Many public utility systems utilize legacy systems to monitor and manage infrastructure. These systems were constructed to control physical machines and had no inherent ability to operate in virtual networks. Consequently, many operators connect these legacy systems to modern computers and networks through gateways, making them susceptible to unauthorized remote access. Simultaneously, operators often cannot update such systems for their security since it usually requires shutting down the whole system.

Interconnected Technology Creates Weakness

In most cases, critical infrastructure systems and networks are not operated directly by their owners but rely on third-party providers for some or all of their operations. This was the case with many local government utility systems that were recently attacked. In most cases, attackers targeted less protected software systems owned by vendors. Because of the interconnectivity of systems operated by the two entities, attackers accessed the main system operated by the local government.

Human Error Is Inevitable Even With Advanced Security Measures

Despite the sophistication of modern cybersecurity measures, attackers still manage to infiltrate systems due to human error. Many employees lack the knowledge and skills to spot suspicious activities, such as phishing emails, which cybercriminals use to bypass even the most advanced perimeter defenses and security software. Attackers often remain undetected for an extended period, which significantly increases the damage.

Essential Cyber Resilience Measures

Cyber resilience requires organizations to adopt not only defensive measures but also procedures that enable uninterrupted operations following successful cyber intrusions. The following practices are essential in achieving cyber resilience.

• Zoning: Separating critical systems from other networks, such as administrative networks
• Multi-factor Authentication: Using additional verification means, such as tokens, when logging in to critical systems.
• Offline Backups: Creating duplicate data sets, including operational instructions, in hardcopy or other formats that remain inaccessible through regular computer networks.
• Testing Cyber Resilience Procedures: Conducting regular simulations to ensure that employees can respond appropriately during an actual incident.

Frequently Asked Questions

1. What is critical infrastructure cybersecurity?

It is a set of protective measures and procedures that critical infrastructure, including power grids, water supply, transportation networks, and healthcare systems, use to safeguard their physical and digital assets from being disrupted.

2. What is the difference between general cybersecurity and critical infrastructure cybersecurity?

General cybersecurity entails generic protective measures that all organizations can use to protect their data and systems. Critical infrastructure cybersecurity, on the other hand, consists of specific procedures and protocols that only critical infrastructure entities can follow.

3. Why are essential systems attractive to cyber attackers?

Critical infrastructure systems are valuable to attackers since they can demand a huge ransom to restore their operations. Many such systems use legacy technology or interconnected systems that make it relatively easy to infiltrate them and disrupt their operations.

4. What are the most significant vulnerabilities in critical infrastructure networks?

The most significant weaknesses stem from the fact that networks such as electric power grids, water treatment facilities, and healthcare institutions are interconnected and sometimes use outdated technology.

5. How can third-party vendors create vulnerabilities in critical infrastructure networks?

Such vendors often have access to the networks to maintain and upgrade existing systems. Attackers can target such entities to use their credentials and gain unauthorized access to the main systems operated by critical infrastructure entities.

6. What steps should organizations take first to improve infrastructure security?

The first step is to conduct a comprehensive risk assessment to identify weak points, such as connected systems, that attackers can use to infiltrate the system.
