Impact of the U.S. Port Strike on National Supply Chain Security


Port strikes may create logistical challenges for companies’ supply chains, but they also expose them to new vulnerabilities. When a breach occurs during disruptions, it can have large consequences for businesses nationwide. Supply chains have a deep interconnectedness of networks, making organizations an easy target for cyberattacks when a port strike occurs. As companies scramble to adapt, keeping cybersecurity a top priority is key to staying ahead.

How the Port Strike Creates Cybersecurity Vulnerabilities

The U.S. port strike may have disrupted the movement of goods, but it has also created potential vulnerabilities in cybersecurity across global supply chains. As companies rush to find alternative routes and suppliers to mitigate halted shipments, they may expose their operations to cyberthreats. 

Supply chains are complex, requiring quick decision-making during disruptions. However, this often results in overlooked security protocols, increasing the risk of cyberattacks. One key factor contributing to these vulnerabilities is the reliance on third-party vendors. 

According to a SecurityScorecard and The Cyentia Institute report, research shows that 99% of Global 2000 organizations have direct connections to vendors that have had a supply chain breach. This is particularly concerning during port disruptions. 

As companies hurry to seek new partners to keep their operations running, they often do so without conducting cybersecurity assessments. Such rushed decisions can create security turmoil, especially since the affected ports account for 1.7% of the world’s containership fleet each week. 

While this percentage may seem small on a global scale, its impact is far-reaching. A wide range of industries — from retail to manufacturing and tech — rely on these ports for imports and exports. Therefore, the disruption has a domino effect across numerous supply chains, affecting more businesses and amplifying further cybersecurity risks.

The Increased Risk of Cyberattacks on Supply Chain Systems

Increased vulnerabilities leave wide open opportunities for cybercriminals to exploit weaknesses within the supply chain.

The biggest risk associated with supply chain disruptions is data breaches. Companies use cloud-based services to coordinate logistics and manage inventory. Rapidly deploying these solutions on multiple platforms can expose data to breaches. 

According to IBM, 40% of breaches involve information stored across several environments — the financial cost of such violations can be staggering. Companies that stored their data in public clouds incurred the highest average of $5.17 million.

Reinforcing Cybersecurity Measures During Supply Chain Disruptions

Strengthening security measures is more critical than ever in times of supply chain abnormalities. With the current volatility, the number of organizations maintaining minimum viable cyber resilience has dropped by 31% since 2022. Several key strategies are available to ensure continued security and smooth operations.

1. Enhance Monitoring and Surveillance of Logistics Networks

One survey found that 52% of companies’ IT departments spend too much time collecting data on their own to monitor for unusual activity. When organizations make changes in the supply chain, manual monitoring of logistics networks gives teams less time to address threats. 

Rather than employing this method, it is better to leverage real-time monitoring tools. These systems automate the detection of suspicious activities and provide greater data visibility. By utilizing such systems, organizations have more time to catch issues before they grow.

2. Implement Rapid Response and Incident Management Plans

Businesses should incorporate a rapid response and incident management plan so they know how to act when a cyberthreat arises. These plans require regular rehearsals and updates to guarantee the cybersecurity team knows which actions to take. 

Therefore, response plans should outline the steps to take during an exposure, including isolating affected networks and implementing backup systems. With well-documented procedures, businesses can reduce the impact of an incident.

3. Strengthen Security Protocols for Alternative Supply Routes

Since businesses may need to reroute shipments or find new suppliers during disruptions, they must thoroughly vet any new partners to ensure they meet cybersecurity standards. This includes assessing their data protection measures, reviewing their security certifications and confirming their industry-standard compliance. While verifying these security protocols may take time, it is worth the effort to minimize vulnerabilities.

Proactive Cybersecurity for Supply Chain Stability

The U.S. port strike brings to light the vulnerabilities that can emerge during a supply chain disruption. As businesses adjust to new suppliers and logistics challenges, they also face increased risks of cyberattacks that can have long-term impacts. Now is the time to reinforce cybersecurity across all facets of the supply chain.
