Data Center: Security Challenges of Critical Infrastructure in the Digital Age

Introduction

Data centers are core infrastructure for the modern digital economy, hosting critical applications such as cloud computing, artificial intelligence, and financial services. However, as their strategic value grows, data centers are facing increasingly severe security threats—from cyberattacks to military strikes, from physical fires to supply chain disruptions. In January 2026, Deutsche Bundesbank reported that its own IT systems alone suffered more than 5,000 cyberattacks per minute. In the recent military conflict between the U.S.-Israeli alliance and Iran, Iran even directly attacked AWS data centers in the Persian Gulf with drones and missiles. These incidents show that data center security is no longer just a technical issue, but has become a key matter of national security and enterprise resilience.

Background: The Central Role of Data Centers

Globally, the number of data centers has exceeded 12,000 and is still expanding rapidly. The Frankfurt region in Germany is one of Europe's most important data center hubs, with 76 data centers, while DE-CIX Frankfurt, a world-leading internet exchange, handles more than 17 terabits per second at peak times, equivalent to nearly 3.5 million people simultaneously watching HD video online.

The importance of data centers is not only reflected in the operation of the internet, but also in the country's economic lifeline and people's livelihoods. In Germany, data centers are explicitly designated as critical infrastructure and receive special protection. In March 2026, the German federal government issued a new Data Center Strategy, planning to double the country's data center capacity by 2030 while reducing dependence on non-European suppliers, further highlighting the central role of data centers in national strategy.

Overview of Incidents: Data Centers Becoming Targets of Multiple Types of Attacks

• In March 2021, a fire broke out at a large data center in Strasbourg, France, taking more than 3.6 million websites offline. Some customers permanently lost data because their backups were stored in the same building.
• During the war in Ukraine, IT infrastructure became a military target, with the aim of hindering military operations and causing large-scale disruption to civilian supply routes.
• In the recent military conflict between the U.S.-Israeli alliance and Iran, Iran launched drones and rockets at three AWS data centers in Bahrain and the United Arab Emirates, causing severe disruption to banking, payment platforms, and other systems. Subsequently, the Iranian leadership published a list on Telegram containing up to 30 other potential targets, including data centers, research facilities, and offices of tech giants such as Google, IBM, Palantir, and Oracle.

These incidents demonstrate that data centers are not only attacked in cyberspace, but may also become legitimate military targets on the physical battlefield. The types of risks have gone beyond the traditional cybersecurity framework.

Technical and Risk Analysis: A Multi-Dimensional Threat Model

1. Cyberattacks: A High-Frequency, Persistent Threat Data centers, as centralized hubs of data, are "high-value targets" for hackers and ransomware organizations. Data from the German Federal Bank shows that its own IT systems record more than 5,000 attacks per minute, reflecting the intensity of attacks faced by large institutions. Although data center network defenses are usually strong, attackers can still infiltrate through supply chains, zero-day vulnerabilities, and other routes.

2. Physical Risks: Fire and Human Sabotage

The Strasbourg fire demonstrated that physical risks can cause regional internet paralysis. More seriously, many customers store backups in the same facility, leading to "total loss" incidents. Data center physical security designs (such as fire protection and surveillance) must meet high standards, but internal operational errors or external sabotage can still have severe consequences.

3. Military Strikes: Strategic Targets in Geopolitical Conflicts

Iran's missile attack on AWS facilities was a landmark event, showing that civilian cloud infrastructure can become a military target even in peacetime. The consequences of such attacks are systemic and may simultaneously affect multiple countries and industries. Data center location strategies must consider geopolitical risks, not just cost and technology.

Enterprise Impact Analysis: Every Data Center Outage Affects Business Lifelines

For any enterprise that relies on data centers, a major outage can bring multiple negative consequences:

• Operational risk: Core business systems become unavailable, leading to transaction interruptions and lower production efficiency. For example, an impact on financial payment platforms can directly cause market liquidity tensions.
• Financial risk: Revenue loss caused by downtime, data recovery costs, and potential legal compensation can be extremely high.
• Compliance risk: Under data protection regulations such as GDPR, data loss may result in hefty fines and regulatory scrutiny.
• Brand risk: Customer trust is hard to restore, especially when enterprises cannot guarantee data security, potentially losing long-term contracts.

Taking the Strasbourg fire as an example, enterprises that lost data not only faced business interruption, but also compliance and reputational crises due to permanent data loss.

Industry Trend Observation: The Dilemma of Expansion and Security

Data centers are undergoing rapid expansion, but they also face triple pressures:

1. AI-driven growth: AI training and inference require massive computing power, driving the construction of more data centers. For example, Germany plans to double capacity by 2030. 2. Policy and sovereignty: Countries are beginning to view data centers as part of "digital sovereignty" and reduce dependence on foreign suppliers, which may lead to supply chain restructuring. 3. Sustainability challenges: The high energy and water consumption of data centers has triggered community protests. For example, environmental groups in Chile successfully blocked an AI data center project, and the Maine legislature in the U.S. once passed a moratorium that was vetoed by the governor, reflecting public concern over resource consumption.

These trends imply that data center security is not just a matter of technical network defense, but also involves location, energy, supply chains, and geopolitical factors.## Defense and Response Recommendations: Building a Highly Resilient Data Center Strategy

In response to the multi-dimensional risks outlined above, enterprises can take the following measures:

Architecture Level - Multi-Region Redundancy: Deploy business operations across multiple geographic locations (preferably in different countries) to avoid single points of failure. - Off-Site Backup: Ensure critical data backups are stored in facilities not co-located with the primary data center to prevent "same-site total loss."

Security Level - Zero Trust Architecture: Implement the principle of least privilege across data center networks, strengthening identity verification and access control. - Continuous Threat Detection: Deploy systems such as EDR/XDR and SIEM, using threat intelligence to monitor anomalous activity in real time.

Physical Security - Multi-Layered Protection: Combine physical isolation, access control systems, video surveillance, intrusion detection, and efficient fire suppression mechanisms. - Military Risk Mitigation: For highly sensitive workloads, consider selecting facilities far from conflict zones and establishing emergency coordination with local governments.

Supply Chain Management - Multi-Cloud Strategy: Reduce dependence on a single cloud service provider to increase resilience. - Third-Party Assessment: Regularly audit cloud service providers' security compliance records and resilience capabilities.

Governance and Compliance - Regular Disaster Recovery Drills: Ensure business continuity plans are effective and assign emergency response procedures to specific personnel. - Regulatory Compliance: Proactively comply with EU and local critical infrastructure protection regulations.

SecurityPost Insight

Data centers have become the "nerve center" of modern society, and their security is directly tied to economic security and national security. The multiple threats revealed in this article—from cyberattacks to physical strikes—show that traditional security thinking centered on network defense is no longer sufficient. Geopolitical factors, physical security, and supply chain resilience must all be incorporated into consideration. For enterprise CISOs, understanding the strategic position of data centers is not only a technical responsibility but also a governance responsibility. In the future, as AI and cloud computing continue to drive data center expansion, security issues will become increasingly complex. We anticipate that legislators, enterprises, and the security community will need to work in synergy to push data center security standards from "advisory" to "mandatory."
