The rule groups events by Reporting IP, Reporting Device, and User. Let's analyze the five events:

Events Received:

1. Reporting IP: 1.1.1.1, Reporting Device: Server101, User: John

2. Reporting IP: 1.1.1.1, Reporting Device: Server101, User: Craig

3. Reporting IP: 1.1.1.2, Reporting Device: Server109, User: Mary

4. Reporting IP: 1.1.1.1, Reporting Device: Server101, User: Craig (Duplicate of #2)

5. Reporting IP: 1.1.1.1, Reporting Device: Server101, User: John (Duplicate of #1)

Grouping Based on:

● Reporting IP

● Reporting Device

● User

Count unique groups:

1. (1.1.1.1, Server101, John) → 2 occurrences (counted as one group)

2. (1.1.1.1, Server101, Craig) → 2 occurrences (counted as one group)

3. (1.1.1.2, Server109, Mary) → 1 occurrence (counted as one group)

Since we need at least one matching event (count >= 1) per group, incidents are created for each unique group.

Total unique groups (incidents created) = 2

● John on Server101 (1.1.1.1)

● Craig on Server101 (1.1.1.1)
