Send your audit logs to a SIEM

Read full documentation on how to use the Dashlane CLI to send your audit logs to a SIEM, here: https://github.com/Dashlane/dashlane-audit-logs (opens in a new tab)

This projects allows you to retrieve your Dashlane's audit log and send them in the SIEM or storage solution of your choice, using FluentBit. At the moment, we provide out of the box configurations for the following solutions:

Azure log analytics workspace
Azure blob storage
Splunk
Elasticsearch

This list is not restrictive, as others destination can be used. You can find the list of supported platforms on FluentBit's website: https://docs.fluentbit.io/manual/pipeline/outputs (opens in a new tab)

Prerequisites

In order to manage the Dashlane audit logs of your business account, you need to generate the credentials that will be used to pull the logs. The procedure can be found here: https://cli.dashlane.com/business (opens in a new tab)

How does it work ?

The Docker image provided leverages the Dashlane CLI tool that will pull the audit logs and send them in your SIEM of choice. By default, when running the image in a container, the logs from DAY-1 will be retrieved, and new logs will be pulled every thirty minutes. To handle the logs, we included FluentBit with this basic configuration file:

[INPUT]
    Name  stdin
    Tag   dashlane

[OUTPUT]
    Name  stdout
    Match *
    Format json_lines

To send the logs to a new destination, you need to enrich this configuration file template and add an OUTPUT section such as described on the following sections. To use your custom configuration file, you need to override the DASHLANE_CLI_FLUENTBIT_CONF environment variable and set the path of your configuration file. The method to pass your file will depend on the plaform you use to run the image.

Accessing the logs

The first step to retrieve the audits logs is to run the custom image we provide and that can be found here: https://hub.docker.com/r/dashlane/audit-logs (opens in a new tab)

This image can run on the platform of your choice. To make a simple test, you can deploy it with Docker by doing so:

Environment variables

DASHLANE_CLI_FLUENTBIT_CONF

Path of the FluentBit configuration file
Default to /opt/fluent-bit.conf

DASHLANE_CLI_RUN_DELAY

Delay between each log pull
Default to 60 seconds

DASHLANE_TEAM_DEVICE_KEYS

Secret key to authenticate against Dashlane servers as the team
Documentation to generate the credentials (opens in a new tab)

Running in Docker

docker pull dashlane/audit-logs
docker run -e DASHLANE_TEAM_DEVICE_KEYS=XXX -it dashlane/audit-logs:latest

Running those commands will create a simple container that pull your business every minutes and and print them on the stdout of the container.

Kubernetes

A helm chart is provided by the repository to deploy the service on Kubernetes.

helm install dashlane-audit-logs dashlane-audit-logs/

Some example of configuration is provided in example/.

SIEM configuration

Azure Log analytics workspace

To send your Dashlane audit logs on Azure in a Log Analytics Workspace, you can use the template provided in the dashlane-audit-logs repository. The template will create a container instance that will automatically pull and run the Dashlane Docker image and send the logs in a ContainerInstanceLog_CL table in the Log Analytics Workspace of your choice. Before deploying the template you will have to provide:

The location where you want your container to run (ex: "West Europe")
Your Dashlane credentials
Your Log Analytics Workspace ID and Shared Key

Click on the button to start the deployment

(opens in a new tab)

Azure blob storage

If you want to send your logs to an Azure storage account, you can use the deployment template we provide in the dashlane-audit-logs repository, which will:

Create a storage account and a file share to upload a custom FluentBit configuration file
Create a container instance running the Docker image with your custom file

You will need:

Your Dashlane credentials
A custom FluentBit configuration file

Click on the button to start the deployment

(opens in a new tab)

Once your container is deployed, copy the following configuration into a file called "fluent-bit.conf".

[INPUT]
    Name  stdin
    Tag   dashlane

[OUTPUT]
    Name  stdout
    Match *
    Format json_lines

[OUTPUT]
    name                  azure_blob
    match                 *
    account_name          ${STORAGE_ACCOUNT_NAME}
    shared_key            ${ACCESS_KEY}
    container_name        audit-logs
    auto_create_container on
    tls                   on
    blob_type             blockblob

Then upload in the storage account you just created. In the Azure Portal, go to Storage accounts, select the one you just created, go to File shares, select fluentbit-configuration and upload your configuration file.

The "blob_type" configuration specifies to create a blob for every log entry on the storage account, which facilitates the logs manipulation for eventual post-processing treatment.

The configuration provided above is meant to be working out of the box, but can be customized to suit your needs. You can refer to FluentBit's documentation to see all available options: https://docs.fluentbit.io/manual/pipeline/outputs/azure_blob (opens in a new tab)

Splunk

If you want to send your logs to Splunk, you need to create a HEC (HTTP Event Collector) on your Splunk instance. As an example, we will show here how to create one on a Splunk Cloud instance.

1- On the Splunk console, go to "Settings / Data input" and click on Add New in the HTTP Event Collector line.

2- Give your collector a name and click Next

3- In the Input settings tab keep the option as is and click on Next

4- In the Review tab, click on Submit. You should see a page indicating that the collector has been created.

The token provided will be used to authenticate and send the logs to your Splunk instance.

You can make a test by running the following command:

curl -k https://$SPLUNK_URL.com:8088/services/collector/event -H "Authorization: Splunk $SPLUNK_TOKEN" -d '{"event": "Dashlane test"}'

If all is working you should receive the following response:

{"text":"Success","code":0}

Finally, to send your Dashlane logs to Splunk, you need to customize your FluentBit configuration file by adding the relevant Splunk configuration:

[OUTPUT]
    Name        splunk
    Match       *
    Host        splunk-instance.com
    Port        8088
    TLS         On
    splunk_token ${SPLUNK_TOKEN}

Here, you just need to change the host parameter and indicate yours, and pass your Splunk token as an environment variable to the container. Once the data are sent, you can query them by going to the "Apps/Search and reporting" menu in the console and type this basic query in the search bar:

index=* sourcetype=*

You should now be able to access your Dashlane audit logs.

Elasticsearch

Work in progress

Output configuration for Elasticsearch

[OUTPUT]
  Name  es
  Match *
  Host host
  Port 443
  tls on
  HTTP_User user
  HTTP_Passwd pwd
  Suppress_Type_Name On

Notes

All configuration are provided as is and designed to work out of the box. If you want customize them, you can consult the FluentBit documentation: https://docs.fluentbit.io/manual/pipeline/outputs (opens in a new tab)
