NSG Flow

Anomali supports the ingestion of NSG Flow logs through the Azure Storage Account.

Azure Storage Account

You can use your existing Azure Storage Account or create a new Azure Storage Account to add a new log source in the Anomali platform.

Onboarding steps

Prerequisites

Step 4: Add NSG Flow as new log source

To add NSG Flow as a new log source on the Anomali platform:

  1. Navigate to Search > Log Source Management.

  2. Click New to add a new log source.

  3. Enter a name for the log source.

  4. (Optional) Enter a description for the log source.

    2. Enter the corresponding value of the parameter. For example, CSV is a file format. Similarly, ".gzip" is a file extension.

Step 5: Configure permissions

You can set permissions to decide which roles can view, add, or edit log sources. To do so, configure the following parameters:

  1. Owner: Select an owner of the view from the list of users. This is the email address of the owner.

  2. Type: Select the type of permission assigned to the view:

    1. Private: Only the owner has read and write privileges, that is, no other user can access or edit the view.

    2. Shared: Allows you to set the read-write privileges for a role that is mapped to different users, granting read-write permissions to all users assigned that role. You can also assign read or write permissions to everyone in your organization.

Step 6: Check log source status

Once added, the status of the log source becomes Create Requested. See Log Source Statuses to understand the different types statuses assigned to log sources.

Step 7: Receive confirmation email

You will receive a notification email from Anomali once you have created a new log source request. The Log Source Management page will show the status as Create Requested.

Once the log source has been provisioned and is ready for use, Anomali will send you another email and the Log Source Management page status for the log source will change to Active.
