The digital transformation of critical infrastructures such as data centers has heightened the importance of robust cybersecurity measures, especially for power and cooling systems. These systems are now integrated into networked environments, often extending to remote servers, cloud services, and mobile devices. While this connectivity improves monitoring and efficiency, it also creates potential vulnerabilities for cyberattacks. This article discusses key cybersecurity risks in power and cooling infrastructure and best practices for mitigating these threats.
Key Cybersecurity Risks in Power and Cooling Systems
1. Network Exposure: Power and cooling systems are increasingly managed via software platforms connected to IP networks. These networks may span both operational technology (OT) and IT environments, opening avenues for cyberattacks if not properly secured.
2. Remote Access and Third-Party Integration: With the rise of remote monitoring and third-party services, data centers often provide external access to their power and cooling systems. Without strict access controls, this can become a vulnerable entry point for hackers.
3. Interconnected Devices: The integration of sensors, cooling systems, and power management devices into broader IT networks can increase the risk of malware attacks if devices are not properly secured.
Best Practices for Securing Power and Cooling Infrastructure
1. Defense-in-Depth Strategy
A layered “Defense-in-Depth” (DiD) approach is essential for protecting data center power and cooling systems. This strategy involves using multiple security controls at different layers, including perimeter firewalls, network segmentation, and access management to limit the potential impact of a cyber breach.
– Perimeter Protection: Firewalls should be employed to restrict unauthorized access, and network entry points must be tightly controlled. Using virtual local area networks (VLANs) or zoning techniques helps isolate OT from corporate IT networks
– Device Hardening: Devices connected to the network, such as cooling units and UPS systems, should have strong access controls and regular security patches
2. Vulnerability Management
Continuous monitoring for vulnerabilities is crucial. Data centers should use intrusion detection systems (IDS) and antivirus solutions to identify suspicious activities and regularly audit both software and hardware systems for potential weaknesses.
3. Secure Remote Access
To minimize risk, remote access to power and cooling systems should be restricted to authorized personnel using encrypted connections such as VPNs. Multi-factor authentication (MFA) should also be used to ensure only legitimate users can access critical infrastructure.
4. Vendor Collaboration
Close collaboration with system vendors is important for staying ahead of emerging cybersecurity threats. Vendors should offer firmware updates, security patches, and guidance on best practices for securing integrated devices.
Simple Defense Strategies to Secure Power and Cooling Infrastructure
Most major UPS manufacturers have built cybersecurity protections into their network management cards to protect connected equipment from unwanted access to the network. Upgrading the network management card to the latest generation, such as the NM3 from Schneider Electric, will ensure that the most current network protections are in place.
Use remote monitoring services from trusted vendors, such as the infrastructure equipment manufacturers, exclusively. Opting for third party remote monitoring services can make your network vulnerable to attacks. Schneider Electric’s EcoStruxure is a proven and secure option.
Conclusion
Cybersecurity is an essential component of any modern power and cooling infrastructure. By adopting a layered security approach, leveraging secure remote access, and collaborating closely with vendors, organizations can mitigate the risks posed by cyber threats. Continuous monitoring and proactive vulnerability management ensure that critical systems remain secure, even in the face of evolving cyberattacks.
