Authorities Microsoft Cloud data protection risks: Current situation

The use of Microsoft cloud services in German authorities is increasing despite data protection concerns. At least six federal states are planning to introduce these services in their administration. The Risk management is facing major challenges.

Dependence of German authorities on cloud services

Lower Saxony and Bavaria are pioneers in the use of Teams and Microsoft 365. Hamburg plans to equip 8,000 to 10,000 administrative workstations with Microsoft 365 by the end of the year. North Rhine-Westphalia and Bremen will follow in 2025. This development shows the growing dependence on cloud services in the public sector.

Lack of European alternatives

The lack of European alternatives is driving the use of Microsoft services. The German government is planning to offer Microsoft 365 via the SAP subsidiary Delos in order to Privacy policy to be complied with. Some states, such as Baden-Württemberg, prefer this solution. OpenDesk, an open source alternative, is being developed but has met with a limited response.

Technical superiority of American suppliers

The technical superiority of American providers is undisputed. However, serious security incidents at Microsoft Azure The risks in 2021 and 2022. Chinese hackers gained access to numerous email accounts, including those of US government employees. As a result, the Cybersecurity and Infrastructure Security Agency (CISA) obliged US authorities to take protective measures. Dealing with Authority data requires the highest safety standards.

The increasing dependence on Microsoft services coupled with security concerns presents authorities with a dilemma between efficiency and data protection.

Data processing in Microsoft 365: Basic aspects

Microsoft 365 is designed as Software-as-a-Service (SaaS) and includes programs such as Word, Excel and PowerPoint. The data processing in this Hybrid cloud-environment is complex and raises data protection issues.

Office 365 processes various types of data. This includes functional data, content data, diagnostic data and data from Connected Experiences. Depending on the category and purpose, Microsoft takes on different roles - as a processor or independent controller.

The German Data Protection Conference (DSK) has determined that it is not possible to prove that Microsoft 365 operates in compliance with data protection regulations. Despite adjustments to the Data Protection Addendum (DPA), personal data continues to be transferred to the USA.

Microsoft plans to introduce an EU Data Boundary by 2024 to ensure the processing of personal data in European data centers. This is intended to address concerns regarding the Azure-infrastructure.

Windows and Office 365 users should note that diagnostic data is collected in order to fix problems and improve the system. A unique advertising ID is also used for personalized advertising.

Data processing in Microsoft 365 remains a complex issue with challenges for data protection and privacy. Compliance.

Functional and content data for Microsoft cloud services

Various types of data are generated when using Microsoft cloud services. These can be divided into functional and content data. Each category plays an important role for the Cloud computing and the Data security.

Definition and types of functional data

Functional data is essential for the operation of cloud services. It includes technical information such as location data for time synchronization or connection details. This data enables the smooth functioning of Microsoft services and contributes to the Compliance with.

Processing of content data

Content data is user-generated information such as texts in Word documents or emails in Outlook. Microsoft acts as a processor here and uses this data exclusively to provide the services. Processing takes place under strict data protection guidelines.

Data protection classification

The legal assessment varies depending on the type of data and processing purpose. A data protection impact assessment revealed 8 problem areas in the use of Office 365, with Microsoft only being able to satisfactorily minimize the risks in 2 areas. Especially with Outlook and Teams, the Data security a critical factor.

Data type Processing Relevance to data protection
Functional data Technical operation Medium
Content data Service provision High
Diagnostic data Analysis and improvement Very high

Users should activate privacy-friendly settings and configure the telemetry functions to limit data collection. House rules for Microsoft 365 use can help to regulate the handling of sensitive data and increase data security.

Diagnostic data and its significance for data security

Diagnostic data plays an important role in the Risk management of the Microsoft cloud. They provide insights into the functioning and security of the systems. The handling of this data is particularly sensitive for public authorities, as it often contains confidential information. Authority data process.

Required diagnostic data

This category includes basic information such as device data and error reports. They are essential for the smooth operation of the applications. Microsoft has severely restricted the processing of this data in order to protect the Privacy policy to comply.

Optional diagnostic data

Optional diagnostic data provides additional insights for product improvement. However, their use can be problematic under data protection law. Authorities should carefully consider which of this data they release.

Storage and processing

The storage and processing of diagnostic data is subject to strict security measures. Microsoft has introduced additional contractual protective measures and has included metadata and diagnostic data as the subject of order processing.

Data type Processing Relevance to data protection
Required diagnostic data Severely restricted Low
Optional diagnostic data Extended Potentially high

For secure handling of diagnostic data, we recommend deactivating telemetry or diagnostic data transmission. Particularly sensitive data should be backed up in encrypted storage services. These measures support authorities in complying with strict Privacy policy.

Connected experiences and their data protection implications

Connected Experiences in Office 365 offer additional functions that require an internet connection. These services enable collaboration on OneDrive documents or translations in Word, for example. However, they also raise questions about data protection.

The use of connected experiences in a Hybrid cloud-environment can be problematic. Data processing cannot simply be justified with Microsoft as the processor. Instead, a joint controllership agreement may be required.

Current statistics show the explosive nature of the issue:

  • 90% of companies consider GDPR compliance essential for cloud solutions
  • 79% demand transparency in the security architecture
  • 67% attach importance to the location of the cloud provider

These figures illustrate the high demands placed on data protection and security, to which Azure and Office 365. Companies should carefully consider the use of Connected Experiences and, if necessary, consider alternative solutions in order to retain control over their data.

Aspect Requirement Relevance for connected experiences
GDPR compliance 90% High
Security transparency 79% Medium
Location of the provider 67% High
