Data Center: Security Threats to Critical Infrastructure and Countermeasures

Introduction

Data centers are the engine of the modern digital economy, carrying the core computing for everything from cloud computing and financial transactions to public services. However, this centralization also makes them high-value targets for security threats. A recent Deutsche Welle report reveals that data centers not only face increasingly frequent cyberattacks, but may also become direct targets in military conflicts. For corporate security decision-makers, understanding the strategic position and multidimensional risks of data centers has become a prerequisite for building resilience.

Event Overview

According to statistics, there are approximately 12,000 data centers globally, of which 76 are in the Frankfurt area, making it one of the most important data center hubs in Europe. The German government has designated data centers as critical infrastructure and released the "National Data Center Strategy" in March 2026, planning to double capacity by 2030 while reducing dependence on non-European suppliers. However, risks are also escalating at the same time. The German Federal Bank reports that its IT systems are subject to more than 5,000 cyberattacks per minute. In 2021, a data center fire in Strasbourg, France, disrupted services for 3.6 million websites, and some customers permanently lost data because backup storage was located in the same building. More concerning, during the Iran war, AWS data centers in Bahrain and the UAE were attacked by drones and rockets, causing large-scale disruptions to banking and payment systems.

Technology and Risk Analysis

The risk surface of data centers is expanding from traditional cyberattacks to physical destruction and military strikes. Attack methods include:

• Cyberattacks: DDoS, ransomware, supply chain attacks, etc., targeting identity systems, cloud environments, and network infrastructure managed by data centers. Attackers often exploit configuration errors, vulnerabilities, or social engineering to enter core systems.
• Physical attacks: Fire, power outages, sabotage, etc. The Strasbourg incident shows that physical failures can cause regional digital service paralysis.
• Geopolitical strikes: As national critical infrastructure, data centers may be considered military targets. Iran's strikes on AWS facilities show that cloud services have become targets in modern conflicts.

Affected assets include not only servers and storage, but also identity systems, cloud environments, and downstream industries such as finance, energy, and transportation that rely on these facilities. The attack chain often breaks through from edge systems and then moves laterally to core data and management planes.

Enterprise Impact Analysis

• For enterprises, any data center disruption can cause chain reactions:- Operational risk: Business continuity and availability of critical applications. The Strasbourg fire took millions of websites offline, rendering businesses unable to trade.
• Financial risk: Downtime losses, data recovery costs, legal compensation, and customer churn. Gartner once estimated that downtime costs an average of approximately $5,600 per minute, with even higher losses for large cloud service providers.
• Compliance risk: As critical infrastructure, data centers must meet stricter regulatory requirements, such as data localization, resilience testing, and reporting obligations.
• Brand risk: Major security incidents can erode customer trust, especially when data loss is involved.
• Data risk: The flaw of keeping backups in the same facility can lead to permanent data loss; even seemingly redundant architectures may have single points of failure.Data centers have become strategic locations in the digital age, and their security is no longer just a technical issue but a core topic of national security and corporate governance. Events have shown that the boundary between cyberattacks and physical attacks is increasingly blurred, and enterprises must abandon the mindset of "compliance equals security" and proactively build resilience. In the future, with the development of AI and edge computing, data centers will further integrate into social infrastructure, and security risks will become even more complex. Corporate decision-makers should recognize that data center security is not solely the responsibility of the IT department, but a strategic issue that requires the joint participation of the CEO, the board of directors, and external stakeholders. Only by incorporating resilient design, redundancy planning, and geopolitical risk assessment into long-term strategy can enterprises maintain continuous operations in an uncertain digital age.
