How do you create a Sentinel Analytics Rule using two tables?

edit

To create a Sentinel Analytics Rule using two tables, you can follow these steps:

1. Determine the two tables you want to use for the rule.
2. Identify the common field(s) between the two tables.
3. Create a join between the two tables using the common field(s).
4. Define the conditions for the rule, which may involve fields from both tables.
5. Set the duration for the rule to run, and configure the notification or action to be taken when the rule is triggered.

For example, suppose you want to create a rule that identifies when a user is accessing sensitive data from an unauthorized location. You might use two tables: one with user access logs and one with a list of authorized locations.

1. Determine the two tables: User Access Logs and Authorized Locations.
2. The common field might be the user ID or IP address.
3. Create a join between the two tables using the common field.
4. Define the conditions for the rule, such as "If a user accesses sensitive data AND their location is not authorized, trigger the rule."
5. Set the duration for the rule to run, and configure the notification or action to be taken when the rule is triggered (e.g., send an alert to the security team, block the user's access, etc.).

By combining data from two tables in this way, you can create more powerful and specific rules for detecting security threats and anomalous behavior.
