To enhance threat detection, investigation, and response, data must be ingested from various sources into Microsoft Sentinel. The ability to pull in data from a wide array of sources is one of Sentinel’s key strengths, as it enables organizations to have a holistic view of activities across their environments.
Azure Activity Log provides data about operations performed on resources in your Azure account. It’s a critical source for monitoring Azure’s infrastructure and services and gaining insight into Azure Resource Manager operational data.
Collecting security events from Windows servers and workstations provides visibility into a wide range of activities on your machines, such as logon attempts, access to resources, and changes to user privileges.
These logs contain valuable data related to user authentication and authorization activities, providing insights into sign-ins, user management actions, and conditional access policies, among other information.
Office 365 audit logs track user and admin activities across Office 365 services, which is crucial for understanding access to and usage of Office 365 applications such as Exchange Online, SharePoint Online, and OneDrive for Business.
Ingest network data for analysis by integrating Firewall logs, DNS logs, and other traffic-related data. Common examples include Azure Firewall, third-party firewalls, and network appliances.
Logs from SaaS applications and other cloud services can be ingested into Microsoft Sentinel. This can include services such as Salesforce, AWS CloudTrail logs, and Google Workspace logs, providing comprehensive monitoring of cloud activities.
Threat intelligence feeds from Microsoft and other providers can be ingested to enhance security event context, allowing analysts to map observed activities against known threats and indicators of compromise.
Microsoft Sentinel can ingest data from Internet of Things (IoT) and Operational Technology (OT) devices, offering security insights into a broader surface of potential vulnerabilities and incidents.
Sentinel offers a range of API connectors for services that are not available as standard connectors, allowing for custom integrations and ingestion of data from various APIs.
Integrate logs from third-party solutions such as antivirus software, endpoint detection and response (EDR) systems, and vulnerability scanners. Notable examples include solutions from Symantec, McAfee, and Fortinet.
Integration Type | Examples | Description |
---|---|---|
Native Connectors | Azure AD, Office 365 | Pre-built connectors provided by Microsoft to easily integrate with Azure or Microsoft services. |
Agent-Based | Windows Security Events | Deploys agents on VMs or on-premises to collect and forward security events. |
Syslog | Network Appliances, Linux Servers | Collects data from systems and devices that support Syslog protocol. |
REST API | API Data Connectors | Custom integrations through RESTful APIs to connect services not natively supported. |
Direct Ingestion | IoT Devices, Custom Applications | Data can be ingested directly into Sentinel using Azure Event Hubs or by leveraging Logstash for transformation. |
When identifying data sources for Microsoft Sentinel, consider the following best practices:
By carefully selecting and integrating the right data sources, analysts can leverage Microsoft Sentinel to its full potential, thereby increasing the efficiency and effectiveness of the security operations center (SOC). Each source contributes uniquely to the overall security picture, enabling comprehensive monitoring, proactive threat hunting, and swift incident response.
Correct Answer: True
Microsoft Sentinel can ingest data from various Office 365 services like Exchange Online, SharePoint Online, and OneDrive for Business.
Correct Answer: False
Microsoft Sentinel is not limited to Azure resources; it can also ingest data from other clouds, on-premises resources, and various security products.
Correct Answer: A, B, C
Data connectors, custom scripts, and Microsoft Graph Security API are all valid ways to ingest data into Microsoft Sentinel. Manual data entry is not a typical method for data ingestion into Sentinel.
Correct Answer: False
While Microsoft Sentinel can ingest Azure AD logs, it typically requires configuration such as enabling diagnostic settings or using data connectors.
Correct Answer: D
Microsoft Sentinel provides direct support for DNS server logs through data connectors. Other logs mentioned might require additional steps or custom connectors for ingestion.
Correct Answer: True
Microsoft Sentinel offers the flexibility to ingest data from third-party cloud providers using various data connectors and APIs.
Correct Answer: B
The Azure Log Analytics agent is commonly used to ingest data from on-premises sources into Microsoft Sentinel.
Correct Answer: True
Microsoft Sentinel can ingest threat intelligence indicators directly using the Threat Intelligence Platforms connector.
Correct Answer: False
Syslog and CEF data usually require an agent, such as the Azure Log Analytics agent or a dedicated Syslog server that forwards the data to Microsoft Sentinel.
Correct Answer: D
Microsoft Sentinel can ingest data from various third-party solutions including AWS CloudTrail, Google Cloud Audit Logs, and IBM QRadar.
Correct Answer: False
Microsoft Sentinel can ingest both structured and unstructured data, allowing for a wide range of data sources to be utilized for analytics.
Correct Answer: True
Custom logs can be ingested into Microsoft Sentinel by using the HTTP Data Collector API (a REST API) or by using the Log Analytics agent for a more integrated approach.
Microsoft Sentinel is a cloud-native security information and event manager (SIEM) platform.
By ingesting data into Microsoft Sentinel, organizations can get a comprehensive view of their security posture, detect threats and anomalies, and respond quickly to incidents.
Microsoft Sentinel can ingest data from a variety of sources, including Azure services, Microsoft 365 services, on-premises data sources, and third-party services.
Data can be ingested into Microsoft Sentinel using built-in connectors, custom connectors, or the Common Event Format (CEF).
Some examples of built-in connectors for data ingestion in Microsoft Sentinel include Azure Active Directory, Azure Advanced Threat Protection, Azure Security Center, Microsoft Cloud App Security, and Microsoft Defender for Endpoint.
Custom connectors can be used to ingest data from sources that don’t have a built-in connector, or to customize the data ingestion process.
The Common Event Format (CEF) is a standard for the exchange of event information between security-related systems.
Organizations should work with their security team to determine which data sources are most relevant for their security needs, and then configure the appropriate connectors in Microsoft Sentinel.
Data quality can be monitored in Microsoft Sentinel using data connectors, workbooks, and queries.
Workbooks provide a way to create custom visualizations and reports based on data ingested into Microsoft Sentinel.
Queries can be used to search and analyze data ingested into Microsoft Sentinel, and can be used to create custom rules and alerts.
Microsoft Sentinel can be integrated with other security tools using APIs, connectors, and automation.
Automation can help organizations reduce manual effort, increase speed and accuracy, and improve overall security posture.
Community resources can provide additional guidance, best practices, and custom content for Microsoft Sentinel users.
Organizations can stay up-to-date with the latest features and capabilities in Microsoft Sentinel by following Microsoft documentation, blogs, and community resources, as well as attending Microsoft events and webinars.
