Entities in Sentinel - Email and Email cluster

In the context of Microsoft Sentinel, the distinction between the "Email" and "Email cluster" entities is important for understanding how email-related data is handled and analyzed for security purposes.

1. Email Entity in Microsoft Sentinel: The "Email" entity represents an individual email. In Microsoft Sentinel, this entity captures detailed information about a specific email, such as the sender, recipients, subject, body, and any attachments. This granular level of detail is crucial for security incident investigations, as it allows security analysts to understand the specifics of emails that may be involved in security incidents, such as phishing attacks or malware distribution.
2. Email Cluster Entity in Microsoft Sentinel: The "Email cluster" entity, on the other hand, refers to a group of related emails that are clustered together based on common characteristics. These characteristics might include similarities in sender, recipient, subject, or patterns in the message content. The purpose of clustering emails is to aid in the identification of broader attack campaigns, where multiple emails might be part of a larger, coordinated attack strategy. By grouping these emails, analysts can address them collectively, enabling a more efficient and effective security response.

In Microsoft Sentinel, understanding these two entities is key to effective email security management. While the "Email" entity provides a detailed view of individual emails, the "Email cluster" entity offers a broader perspective, enabling analysts to identify and address attack patterns or campaigns.

For more detailed information on how Microsoft Sentinel utilizes these entities and how they can be integrated into your organization's security strategies, you can refer to the official Microsoft Sentinel documentation on Microsoft Docs.
