In today’s digital landscape, data security and privacy have become paramount concerns for organizations worldwide. With the increasing frequency and sophistication of cyber threats, it is essential to implement robust security measures to safeguard sensitive information. Microsoft Defender for Identity offers a comprehensive solution that not only collects and analyzes valuable data but also ensures the highest level of security and privacy for organizations. In this blog post, we will explore the data storage, encryption, and privacy practices employed by Microsoft Defender for Identity.
The data generated and collected by Microsoft Defender for Identity is stored in Microsoft-managed data centers located in various regions worldwide. These data centers are strategically designed to meet stringent security, privacy, and compliance standards. Microsoft Defender for Identity data centers adhere to globally recognized certifications, including ISO 27001, SOC 1, SOC 2, and SOC 3, as well as regulatory requirements such as the General Data Protection Regulation (GDPR). Currently, data centers for Defender for Identity are deployed in Europe, UK, North America/Central America/Caribbean, Australia East, and Asia, ensuring proximity to your respective Azure Active Directory (Azure AD) instances.
Microsoft Defender for Identity employs robust encryption techniques to safeguard data both during transit and at rest. Data in transit is protected using encryption algorithms such as AES-256 and SSL/TLS to secure network communication. This ensures that any information transmitted between your configured servers, such as domain controllers and member servers, and the Defender for Identity service remains secure and confidential. Additionally, data at rest is also encrypted, adding an extra layer of protection to sensitive information stored in the service’s dedicated database.
Defender for Identity collects and stores specific information from your configured servers for administration, tracking, and reporting purposes. This includes network traffic to and from domain controllers, such as Kerberos authentication, NTLM authentication, and DNS queries. Security logs, such as Windows security events, are also collected to provide comprehensive insights into potential threats. Moreover, Defender for Identity captures Active Directory information, including the structure, subnets, and sites, enabling accurate threat detection and analysis. Additionally, entity information like names, email addresses, and phone numbers may be collected to enhance the identification and response to security incidents.
It is crucial to note that any directory information that can be accessed by a non-privileged user in the Active Directory has the potential to be transmitted to Microsoft Defender for Identity. To ensure compliance with privacy regulations, Microsoft provides a detailed list of potential personal information available in Active Directory. This information is outlined in the “Personal-Information property set” article, which helps organizations understand the types of data that might be collected during the Defender for Identity service’s operation.
