Compliance in Data Centers: Key Standards and Future Trends

Non-compliance with these requirements can have severe consequences, ranging from hefty fines and legal actions (e.g., GDPR penalties) to operational interruptions and financial losses.

Data centers must comply with a variety of international and national security standards, including:

• International standards such as ISO 27001, ISO 27017, ISO 27018, and ISO 27701

• U.S. standards such as SOC 1 and SOC 2

• European regulations such as NIS-2, DORA, and GDPR

This document provides an overview of the relevant standards, highlights three important future trends in compliance for data centers, and introduces the software portfolio of the Beta Systems Group, which helps data center operators meet compliance requirements.

Legally speaking, standards are not mandatory compliance requirements with criminal consequences. However, in practice, they serve as indispensable quality benchmarks considered a minimum requirement in the business environment. Below is an overview of these standards.

1.1 ISO/IEC 27001 – Information Security Management System (ISMS)

ISO/IEC 27001 is the leading international standard for implementing and certifying an Information Security Management System (ISMS). It ensures that companies and organizations establish systematic processes to protect their information, effectively manage risks, and continuously improve security measures.

The primary objectives of ISO 27001 include protecting the confidentiality, integrity, and availability of information. The standard requires companies to:

• Conduct comprehensive risk assessments to identify threats and vulnerabilities.

• Implement appropriate security measures and controls to mitigate risks.

• Develop and document clear security strategies and policies.

• Perform regular audits and reviews to ensure continuous improvement.

• Establish an incident management system to respond to security incidents effectively.

1.2 ISO/IEC 27017 – Cloud Security Controls

ISO/IEC 27017 extends ISO/IEC 27001 by providing specific security requirements for cloud service providers. It addresses risks in cloud environments caused by shared resources, virtual infrastructures, and external access points.

Key measures include:

• Identity management: Strong authentication and authorization mechanisms to control cloud access.

• Network segmentation: Separation of customer data from internal administrative networks to minimize data leakage risks.

• Access rights management: Strict control of administrator rights and role segregation to prevent insider threats.

• Data encryption: Protection of data at rest and in transit through modern encryption methods.

• Monitoring and logging: Continuous surveillance and logging of access and security-critical events.

This standard also defines clear responsibilities between cloud providers and customers and sets requirements for data isolation to prevent unintentional mixing of customer data.

1.3 ISO/IEC 27018 – Protection of Personal Data in the Cloud

ISO/IEC 27018 is an international standard designed to protect personal data in cloud environments. It extends ISO/IEC 27001 and includes additional requirements for cloud service providers acting as data processors under GDPR.

Key requirements include:

• Transparency obligations: Cloud providers must clearly inform customers about how and where personal data is stored, processed, and protected.

• Customer control over their data: End users must have the right to access, correct, delete, and transfer their personal data.

• Purpose limitation: Personal data must only be processed for the agreed-upon purpose.

• Mandatory breach notifications: Security breaches affecting personal data must be promptly reported to customers.

To enhance data protection, ISO 27018 mandates encryption, multi-factor authentication, and data anonymization.

1.4 ISO/IEC 27701 – Privacy Information Management System (PIMS)

ISO/IEC 27701 extends ISO/IEC 27001 by integrating data protection requirements into an existing ISMS. It serves as an internationally recognized standard for protecting personal data.

Key aspects include:

• Identification of personal data: Organizations must determine what personal data they process and how it is protected.

• Data Protection Impact Assessments (DPIA): Mandatory risk analysis for data privacy.

• Assigned responsibilities: Clear designation of roles, including a Data Protection Officer (DPO).

• Rights of data subjects: Ensuring individuals can exercise GDPR rights such as access, correction, deletion, and portability.

• Data minimization and retention limits: Collecting only necessary personal data and limiting its storage.

ISO 27701 helps data centers comply with GDPR and establish a structured and auditable privacy framework.

2.1 SOC 1 (Service Organization Control 1)

The SOC 1 (Service Organization Control 1) report is a U.S. standard specifically designed for organizations that provide services to financial institutions or other businesses with stringent financial reporting requirements. Developed by the American Institute of Certified Public Accountants (AICPA), it serves as an audit report evaluating a service provider’s internal control systems over financial data.

While international standards like ISO/IEC 27001 define a general Information Security Management System (ISMS), SOC 1 focuses specifically on the effectiveness of internal controls related to financial reporting.

Financial service providers, banks, insurance companies, and other regulated entities must ensure that their external service providers have effective control mechanisms in place to maintain the integrity and confidentiality of financial transactions. Since financial institutions often rely on outsourcing partners, they depend on reliable audit reports to demonstrate compliance with regulatory requirements.

A SOC 1 report confirms that a service provider’s internal control systems function properly and do not negatively impact financial reporting. This is particularly relevant for cloud providers and data centers that supply IT infrastructure to financial institutions.

A SOC 1 report is conducted through an independent audit by certified public accountants. The audit assesses internal control systems, focusing on:

• Data integrity: Ensuring financial data is processed completely, accurately, and securely.

• Access control: Managing and restricting access to sensitive financial data.

• Change management: Reviewing how modifications to financial systems are documented and controlled to prevent errors or fraud.

• Security measures: Implementing technical and organizational controls to ensure the confidentiality and availability of financial data.

2.2. SOC 2 (Service Organization Control 2)

The SOC 2 (Service Organization Control 2) report is another audit standard developed by AICPA, specifically focused on data privacy, availability, and confidentiality. While SOC 1 addresses financial reporting, SOC 2 evaluates an organization’s operational and technical security controls implemented to protect customer data.

The SOC 2 report is based on the Trust Services Criteria (TSC), which consists of five key principles:

1. Security: Protecting systems and data from unauthorized access (e.g., firewalls, intrusion detection systems, and access controls).

2. Availability: Ensuring that services and systems remain highly available through redundancy and contingency measures.

3. Processing integrity: Guaranteeing that data is processed correctly, completely, and without errors.

4. Confidentiality: Safeguarding sensitive business data and personal information through encryption and access restrictions.

5. Privacy: Adhering to data protection regulations and laws (e.g., GDPR, CCPA) to prevent data misuse or unauthorized access.

Unlike ISO 27001, which requires a comprehensive ISMS, SOC 2 focuses more on practical security measures and controls that a company implements. Additionally, SOC 2 is more customer-oriented, as businesses use this report to transparently demonstrate their security measures to potential clients or partners.

3.1 NIS-2 (Network and Information Security Directive 2)

The NIS-2 Directive (Network and Information Security Directive 2) is a European regulation aimed at significantly enhancing cybersecurity in critical infrastructures. It strengthens the original NIS Directive from 2016 and was developed to address the growing threats posed by cyberattacks more effectively.

NIS-2 expands its scope to include essential and important entities classified as critical infrastructure, such as data centers and cloud service providers.

These entities are subject to stricter security requirements to detect, prevent, and mitigate cyberattacks. They must implement proactive security measures, including:

• Risk management systems to continuously monitor threats.

• Technical security measures such as firewalls, intrusion detection systems, and access controls.

• Incident response plans to ensure a swift reaction to security incidents.

• Employee training programs to raise cybersecurity awareness.

A key requirement is that organizations must demonstrate they have a robust cybersecurity strategy and adhere to best practices for IT system security. Another critical element of NIS-2 is the stricter mandatory reporting of security incidents. Companies are required to report cyberattacks and other security-related incidents within strict deadlines.

With these stringent requirements, the EU aims to ensure that data centers and other critical infrastructures are better prepared for cyber threats and can identify and mitigate risks at an early stage.

Unlike ISO/IEC 27001 (which is voluntary), NIS-2 is a mandatory EU regulation that imposes stricter requirements and legal penalties on critical infrastructure entities. For instance, while ISO 27001 does not require specific incident reporting, NIS-2 mandates the reporting of security incidents within 24 to 72 hours to the relevant authorities, with severe fines for non-compliance.

3.2 DORA (Digital Operational Resilience Act)

The Digital Operational Resilience Act (DORA) is an EU regulation specifically designed for the financial sector to enhance resilience against cyberattacks and IT disruptions. Given the increasing digitalization of the financial industry and the rising number of cyber threats, DORA ensures that banks, insurance companies, and other financial service providers have robust IT security measures in place.

DORA was introduced as part of the EU’s digital strategy and came into effect on January 16, 2023. Affected entities have until January 17, 2025, to implement the new requirements, which are enforceable through financial penalties.

The regulation imposes strict requirements on the digital infrastructure of financial institutions to ensure operational continuity in the event of a cyberattack or technical failure.

Key requirements include:

• IT resilience risk management: Financial institutions must implement comprehensive risk management strategies for their IT systems, including technical and organizational measures to identify and mitigate vulnerabilities.

• Security requirements for third-party providers: IT service providers that support critical infrastructure (e.g., cloud providers) are also subject to DORA regulations. Financial institutions must ensure that their external IT service providers implement adequate security measures.

• Mandatory reporting of IT incidents: Financial institutions are required to report significant IT incidents within short deadlines to the authorities. This requirement is similar to NIS-2 but specifically tailored to the financial sector.

• Stress testing and resilience assessments: Organizations must conduct regular scenario analyses and stress tests to evaluate their resilience against cyber threats. This ensures that critical business processes can be maintained even under extreme conditions.

Unlike other regulations such as ISO/IEC 27001, which primarily focus on general information security management, DORA explicitly targets IT resilience. This includes:

• Protection against system failures and cyberattacks: Ensuring rapid recovery of business operations after disruptions

• Mandatory regular security audits and testing

• Stringent IT governance and risk management requirements

DORA goes beyond ISO 27001 by not only requiring information security measures but also ensuring the operational stability of IT systems within financial institutions.

3.3 GDPR (General Data Protection Regulation)

The General Data Protection Regulation (GDPR) is the primary EU regulation governing the protection of personal data. It establishes clear requirements for the processing, storage, and security of personal data to strengthen individuals’ rights.

Organizations must ensure that data is processed lawfully, transparently, and for a specific purpose. Additionally, the principle of data minimization applies, meaning that only necessary data should be collected and stored.

For data centers and cloud service providers, GDPR is particularly important. As data processors or controllers, they are required to implement strict technical and organizational measures to protect data. These include encryption, access controls, and Data Protection Impact Assessments (DPIAs). Additionally, there is a mandatory requirement to report data breaches within 72 hours.

Non-compliance with GDPR can result in severe fines of up to €20 million or 4% of annual global turnover, whichever is higher. Therefore, GDPR compliance is essential, especially for companies providing cloud services or IT infrastructure.

4.1 Impact of AI and Automation on Compliance

The use of AI and automation is transforming how companies manage security and compliance processes. These technologies help reduce human errors, improve efficiency, and detect emerging threats in real-time.

Traditional security solutions are often reactive, identifying and addressing threats only after an attack has occurred. In contrast, modern AI-driven systems can analyze anomalies and potential attacks in real-time. For instance, machine learning models can detect unusual data access patterns or network behavior early and initiate appropriate countermeasures. For data centers, this significantly enhances security by enabling proactive threat mitigation.

Regulatory requirements such as ISO 27001, NIS-2, DORA, and GDPR mandate a wide range of security measures that must be regularly reviewed and documented. Automated Compliance Management Systems (CMS) simplify this process by continuously monitoring policies and security measures, identifying deviations in real-time, and automatically generating reports for audits and certifications.

Automation makes compliance management more efficient and less error-prone, helping data centers fulfill their legal and security obligations more effectively.

Despite these advantages, increased automation also presents challenges. AI systems must be secure, transparent, and explainable to meet regulatory requirements. Additionally, there is a risk that cybercriminals could manipulate AI systems to bypass security measures.

Data centers must therefore ensure that AI algorithms are regularly reviewed and adjusted, automated systems are supervised by human experts, and ethical and regulatory considerations are integrated into AI-based security solutions.

4.2 Stricter Regulations and International Harmonization

Regulatory requirements for data centers are increasing worldwide. Stricter regulations and the harmonization of international compliance standards are key trends that present both challenges and opportunities for data center operators. As digitalization advances and cyber threats grow, governments and international organizations are focusing on unified security and data protection standards to better safeguard businesses, critical infrastructure, and personal data.

Data centers are at the core of global IT infrastructure and must comply with numerous compliance requirements. This means they need to continuously adapt their security and compliance strategies to mitigate legal risks and avoid heavy fines.

Historically, companies have had to comply with different regulations across various countries, leading to high administrative burdens. A key future trend is the international harmonization of compliance requirements. The goal is to establish globally unified standards for information security and data protection, making compliance easier for businesses and supporting global business models.

Examples of these developments include aligning ISO standards with regulatory requirements (e.g., expanding ISO 27001 with privacy protection through ISO 27701) and EU-U.S. collaborations on data protection (e.g., the new EU-U.S. Data Privacy Framework as a successor to the Privacy Shield).

4.3 Sustainability Requirements (ESG Criteria)

Sustainability is becoming an increasingly important factor in data center compliance. Environmental, Social, and Governance (ESG) criteria are gaining significance as regulations, market demands, and societal expectations push data center operators toward more sustainable business models. In addition to legal requirements such as the EU Taxonomy Regulation and the Corporate Sustainability Reporting Directive (CSRD), companies are voluntarily adopting eco-friendly solutions to improve their carbon footprint.

To meet growing sustainability requirements, data centers must optimize energy consumption, reduce CO₂ emissions, and implement resource-efficient technologies.

Beyond voluntary sustainability measures, data centers are increasingly required to comply with legal mandates. ESG reporting is becoming mandatory for many businesses, particularly in the EU, where the CSRD will require companies to disclose their sustainability performance starting in 2024. Additionally, the EU Taxonomy sets clear criteria for sustainable investments, influencing investors and customers to favor environmentally friendly data centers.
