Azure Database for MySQL

Overview

Azure Database for MySQL provides fully managed, enterprise-ready community MySQL database as a service. The service is developed and managed by Microsoft Corp.

The following Sekoia.io built-in rules match the intake Azure Database for MySQL. This documentation is updated automatically and is based solely on the fields used by the intake which are checked against our rules. This means that some rules will be listed but might not be relevant with the intake.

Extracted Fields

The following table lists the fields that are extracted, normalized under the ECS format, analyzed and indexed by the parser. It should be noted that infered fields are not listed.

Name Type Description
group.name keyword Name of the group.
host.hostname keyword Hostname of the host.
source.ip ip IP address of the source.
user.name keyword Short name or login of the user.

Configure

This setup guide will show you how to forward events produced by Azure MySQL service to Sekoia.io.

Theses changes have to be made from the Azure Web Portal.

Azure Event Hubs

As a prerequisite, you need to choose an existing resource group, or create a new one (e.g. company-resource-group).

Retrieve your Subscription ID

You also need your Subscription ID if you don't have a default one.

In Azure Web Portal:

  1. Navigate to: Home > Cost Management + Billing > Subscriptions
  2. From there, copy the relevant Subscription ID that will be used in the command line (e.g. uuid)

Create the Event Hubs

Use Azure PowerShell (within Cloud Shell interface for example) to create a namespace (e.g. company-eventhub) and a specific Event Hub (e.g. mysql-event) within your resource group (e.g. company-resource-group)

PS Azure:\> az eventhubs namespace create --name company-eventhub --resource-group company-resource-group --enable-kafka true --subscription uuid
PS Azure:\> az eventhubs eventhub create --resource-group company-resource-group --namespace-name company-eventhub --name mysql-event --message-retention 3 --partition-count 4 --subscription uuid

Info

Please replace :

  • company-resource-group with the name of your resource group
  • uuid with your subscription ID retrieved previously (see below)

Create “Shared Access Policies”

  1. Navigate to Home > Event Hubs> company-eventhub - Shared access policies

    • From there, you can create a policy (e.g. RootManageSharedAccessKey) with the claims Manage, Send and Listen and note the Primary Key that will be used as the SharedAccessKey
  2. Navigate to Home > Event Hubs > company-eventhub > mysql-event - Shared access policies

    • From there, you can create a policy (e.g. sekoiaio) with the claims Listen
    • Once created, click on the policy and save the Connection string-primary key, to be sent to Sekoia.io
  3. Navigate to Home> Event Hubs> company-eventhub> mysql-event - Consumer groups

    • From there, you can create a consumer group (e.g. sekoiaio)

Create a Blob Storage for Checkpointing

In order to allow Sekoia.io, keep track of the consumed events, the next step consists in creating a dedicated Azure Blob Storage.

To proceed, you can use Azure PowerShell:

PS Azure:\> az storage account create --name "sekoiaiocheckpoint" --resource-group "company-resource-group"
PS Azure:\> az storage container create --name "mysql-event" --account-name "sekoiaiocheckpoint"

Info

The container name, here mysql-event should be the same as the Event Hub’s one. You also need to replace company-resource-group with the name of your resource group.

Finally, you have to retrieve the connection string from Azure Web Portal by going in Storage Accounts, then in the created storage (sekoiaiocheckpoint) and finally in the Access Keys section. After clicking on Show keys, you can copy the first of the two connection strings.

Azure MySQL

You need to activate and configure the Azure MySQL diagnostic settings (e.g. company-mysql). To configure these settings, follow these steps:

  1. Navigate to Home > SQL databases (e.g. company-mysql) > Monitoring > Diagnostic settings
  2. Add a new diagnostic setting, select Stream to an event hub and click on Configure
  3. Select the previously created Event hubs, Event Hub and SharedAccessKey
  4. In the log section, select MySqlAuditLogs and MySqlSlowLogs
  5. Choose a name for this configuration and click on Save

Forward the Connection Keys to Sekoia.io

Finally, please send to Sekoia.io the following information:

  • Azure Event Hub’s Connection string-primary key (e.g. "Endpoint=sb://company-eventhub.servicebus.windows.net/;SharedAccessKeyName=sekoiaio;SharedAccessKey=XXXXXX;EntityPath=mysql-event")
  • Azure Event Hub’s consumer group name (e.g. sekoiaio)
  • Azure Blob Storage’s connection string (e.g. "DefaultEndpointsProtocol=https;AccountName=sekoiaiocheckpoint;AccountKey=XXXXX")
