Construction Cybersecurity: Risks & Risk Management Strategies

Construction companies rely heavily on third-party vendors, which can introduce significant cyber risk if not properly managed. A vendor with weak cybersecurity controls can become an entry point for attackers, which can exposure your own systems and result in an attack.

How to Manage This Cyber Risk

Key best practices include maintaining a comprehensive inventory of vendors categorized by criticality, conducting regular vendor risk assessments and implementing continuous monitoring. Companies should also establish and test business continuity plans to ensure operations can continue if a vendor experiences an outage.

Wire transfer fraud is one of the most frequent sources of loss under both cyber and crime policies. Given the high volume of payments in construction, attackers often target payment workflows to redirect funds. Once funds are transferred, recovery is often difficult, especially if not identified within a short timeframe.

How to Manage This Cyber Risk

Organizations should implement strict payment controls, including limiting authorization to a small group of individuals and adopting layered approval processes such as a 1-2-1 method (one reviewer, two approvals and executive sign-off). Multi-factor authentication should be required for all transactions, along with call-back verification procedures using pre-established contact information, particularly for any payment changes. New vendors should undergo verification procedures before any transactions are initiated.

IoT technologies are increasingly used on jobsites to improve safety, productivity and operational visibility. However, these connected devices also expand the attack surface. Unpatched or outdated devices can serve as entry points for attackers, providing access to corporate networks and sensitive project data.

How to Address This Cyber Threat

Companies should maintain an up-to-date inventory of connected devices, remove unauthorized or unused equipment and segment IoT devices from core corporate networks. A formal patch management program is critical to ensure devices receive timely security updates. Strong user credentials, access controls and regular phishing awareness training further strengthen defenses.

Ransomware continues to be a leading cyber threat across all industries, including construction. Attacks can halt operations, delay projects and create significant financial and contractual impacts. In many cases, business interruption costs exceed the ransom itself. Beyond the immediate financial loss, these events can also result in reputational harm, eroding trust with clients, partners and stakeholders.

How to Address This Cyber Threat

Organizations should implement robust backup strategies, ensure backups are tested regularly and develop incident response plans that include ransomware scenarios. Planning for operational continuity, including manual workarounds and communication protocols, is essential to minimize disruption.

Phishing remains one of the most common attack methods, where employees are tricked into clicking malicious links or sharing sensitive information. In a phishing incident, cybercriminals will typically pose as a trusted sender to request account details or initiate payments. Email is frequently used to execute these attacks, though text, social media and phone calls can also be leveraged as effective scam tactics.

How to Manage This Cyber Risk

Employees should receive regular training on identifying phishing scams and alerting them to the IT department to prevent incidents from occurring. Simulated attacks conducted by the organization can also be an effective way to assess staff readiness and correct any security awareness gaps. Additionally, multi-factor authentication can help ensure that even if a cybercriminal receives account credentials, their access is blocked.

The rapid growth of artificial intelligence and digital infrastructure is driving a surge in data center construction. These facilities host and process vast amounts of sensitive information, making them prime targets for cyber attacks. A successful breach can result in widespread operational disruption and significant financial impact across multiple organizations.

How to Manage This Cyber Risk

The following cybersecurity practices can help to mitigate risks to data center construction:

• Designing secure infrastructure with network segmentation

• Isolating operational technology (such as building management systems) from IT environments

• Carefully vetting vendors

Ongoing protection requires strong governance frameworks, strict access controls, continuous monitoring and regular testing. Given the critical role of uptime, resilience planning, including redundancy and incident response, is essential. As data centers often involve shared responsibility between owners, operators and tenants, clearly defined roles and security expectations are key to reducing risk.
