Snowflake Integration

Panther can be configured to write processed log data to one or more AWS-based Snowflake database clusters. This allows you to join Panther processed data with your other data sources in Snowflake.

Integrating Panther with Snowflake enables Panther data to be used in your Business Intelligence tools to make dashboards tailored to you operations. In addition, you can join Panther data (e.g., Panther alerts) to your business data, enabling assessment of your security posture with respect to your organization.

For example, you can tally alerts by organizational division (e.g., Human Resources) or by infrastructure (e.g., Development, Test, Production).

Panther uses Snowpipe to copy the data into your Snowflake cluster.

Configuration Overview

This guide assumes you already have a Snowflake instance in AWS.

Ideally, your Panther deployment and Snowflake instance are in the same AWS region. Having both Panther and Snowflake in the same region lowers latency for queries and data movement (relative to cross region communications).

Panther uses two Snowflake users/roles to access your Snowflake instance:

  1. A read only user/role for queries

  2. An admin user/role with strict permissions only to the Panther databases to

    create tables when new log sources are onboarded into Panther.

There are 9 steps to configuring Panther integration with Snowflake.

  1. Security Team: Gather configuration information from Panther

  2. DBA: Gather configuration information from Snowflake

  3. DBA: Create the Panther databases in Snowflake

  4. DBA: Create a read only role and an administrative role in Snowflake (limited to Panther tables)

  5. DBA: Create a read only user and an administrative user in Snowflake

  6. DBA: Create a stored procedure to make creating AWS Secrets easier

  7. AWS Admin: Create a KMS key in your AWS account for Panther Snowflake Secrets

  8. AWS Admin: Create a read only user AWS Secret and an administrative user AWS Secret

  9. Panther (SaaS) or Customer (CloudPrem): Deploy Panther with Snowflake enabled

Gather configuration information from Panther

Go to the Settings page of Panther and select General Settings. There you will find:

  • Snowflake ReadOnly Lambda Role ARN

  • Snowflake Admin Lambda Role ARN

Keep these ARNs handy, we will use this later.

Gather configuration information from Snowflake

In order to configure Panther, you need to get the SNOWFLAKE_IAM_USER from Snowflake.

In a Snowflake SQL shell execute the below sql, replacing myaccountid with your AWS account ID and myaccountregion with the account's region:

SELECT system$get_aws_sns_iam_policy('arn:aws:sns:myaccountregion:myaccountid:panther-processed-data-notifications');

You should see a response of:

{
"Version":"2012-10-17",
"Statement":[
{
"Sid":"1",
"Effect":"Allow",
"Principal":{
"AWS":"arn:aws:iam::34318291XXXX:user/k7m2-s-v2st0722"
},
"Action":["sns:Subscribe"],
"Resource":["arn:aws:sns:myaccountregion:myaccoundid:panther-processed-data-notifications"]
}
]
}

In the above example, the SNOWFLAKE_IAM_USER is the AWS attribute arn:aws:iam::34318291XXXX:user/k7m2-s-v2st0722. Keep this handy, we will use this later.

Create the Panther databases in Snowflake

Execute in Snowflake SQL shell:

USE ROLE SYSADMIN;
---------------- databases
CREATE database IF NOT EXISTS panther_logs;
CREATE database IF NOT EXISTS panther_rule_matches;
CREATE database IF NOT EXISTS panther_rule_errors;
CREATE database IF NOT EXISTS panther_cloudsecurity;
CREATE database IF NOT EXISTS panther_views;
CREATE database IF NOT EXISTS panther_stored_procedures;

Create a read only role and an administrative role in Snowflake

NOTE: be sure to update <your warehouse> in the first line below to the desired Snowflake warehouse name.

We recommend you create a dedicated Panther warehouse (e.g., PANTHER_WH), so that you can easily track costs and resize capacity independently of other Snowflake resources.

Execute in Snowflake SQL shell:

SET WAREHOUSE_NAME = '<your_warehouse>';
USE ROLE SECURITYADMIN;
--------------- create panther_readonly_role
CREATE ROLE IF NOT EXISTS panther_readonly_role;
---------------- grants for panther_readonly_role

Create a read only user and an administrative user in Snowflake

NOTE: set <your_readonly_password> and <your_admin_password> below. Execute in Snowflake SQL shell:

USE ROLE SECURITYADMIN;
-- panther_readonly user
CREATE USER IF NOT EXISTS panther_readonly password='<your_readonly_password>';
GRANT ROLE panther_readonly_role
TO USER panther_readonly;
ALTER USER panther_readonly
SET default_role = panther_readonly_role;
-- panther_admin user
CREATE USER IF NOT EXISTS panther_admin password='<your_admin_password>';
GRANT ROLE panther_admin_role
TO USER panther_admin;
ALTER USER panther_admin
SET default_role = panther_admin_role;

Create a stored procedure to make creating AWS Secrets easier

Define this stored procedure that will create a JSON document you can use to cut-n-paste into AWS Secret Manger (saving typing). Execute in Snowflake SQL shell:

USE ROLE SYSADMIN;
CREATE or replace FUNCTION panther_stored_procedures.public.generate_secret(USN VARCHAR, PWD VARCHAR, WHS VARCHAR, HST VARCHAR)
RETURNS OBJECT
LANGUAGE SQL
STRICT
AS
$$
SELECT object_construct('account', current_account(),
'user', USN ,
'password', PWD ,
'host',HST,
'port','443',
'warehouse',WHS) AS SECRET
$$;
-- Customize the values here to match your password, a compute warehouse you will be using, and your hostname.
-- The hostname is usually "<something>.snowflakecomputing.com" from the URL used to log into your cluster.
-- SELECT panther_stored_procedures.public.generate_secret('panther_readonly','password123','COMPUTE_WH','<something>.snowflakecomputing.com');

Create a KMS key in your AWS account for Panther Snowflake Secrets

You will use this key to encrypt the Snowflake secrets that we will store in your AWS account as part of Step 3.

  • Log in to your AWS account

  • (Optional) Go to the same region that your Snowflake account is in

  • Go to KMS service

  • Click on Create a key

  • Pick Symmetric for the type and click Next

  • Set the alias to panther-secret. Click Next. On the next page Click Next (accept defaults)

  • Click on Add another AWS Account and enter the account id where Panther is installed.

  • Click Next and then click Finish.

Create a read only user AWS Secret and an administrative user AWS Secret

You will use AWS Secrets Manager to store the Snowflake user password. It will be configured to only allow access from a single lambda function in the Panther account.

Repeat the process below, once for panther_readonly user and once for the panther_admin user.

  • Access the AWS Secrets Manager via the console and select Store a New Secret button on the page.

  • You will be presented with a page titled Store a new secret. Select Other type of secrets from the list of types. Specify the following key/value pairs:

Field

Description

account

The name of your Snowflake account. It can be found by executing SELECT CURRENT_ACCOUNT()

user

Snowflake user you created earlier, either panther_readonly or panther_admin

password

The Snowflake user password that you created in Step 1

host

This is usually <something>.snowflakecomputing.com from the URL used to log into your cluster.

port

Use 443 unless you have configured differently

warehouse

The name of your Snowflake active warehouse

You can enter the above by hand OR switch to JSON editor and run the following command in a Snowflake SQL shell, plugging in the appropriate values for the 4 parameters, once for the panther_readonly user and once for the panther_admin:

SELECT panther_stored_procedures.public.generate_secret(<user>,<password>,<warehouse>,<host>);

Then copy-paste the result into each of the 2 secrets "plaintext" editor tab.

  • Select panther-secret from the dropdown under Select the encryption key.

  • Click Next.

  • You will be presented with a screen asking for the name and description of the secret. Fill these in and click Next.

  • The next screen concerns autorotation, just click the Next button.

  • Finally, you will be presented with an overview screen. Scroll to the bottom and click the Store button.

Update Permissions

We need to configure the permissions for the Panther AWS secret such that only specific Panther lambdas have access to the Snowflake secret.

The Panther panther-snowflake-api will use the panther_readonly user for user queries while the panther-snowflake-admin-api will use the panther_admin user to create tables when new log sources are onboarded.

Go to the console and select the secret you created above. On the overview screen click on the Edit Permissions button. Copy the below policy JSON, substituting the appropriate <lambda role>, either:

  • panther-snowflake-api role collected in the first step

  • panther-snowflake-admin-api role collected in the first step

For the value of <secret ARN> use the ARN of the secret just created.

{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {"AWS": "<lambda role>" },
"Action": "secretsmanager:GetSecretValue",
"Resource": "<secret ARN>"
}
]
}

Then click the Save button.

Make a note of the arn for the secret. We will use this later.

SaaS Users

Send to your Panther point of contact (POC):

  • SNOWFLAKE_IAM_USER collected in the first step

  • ARN for the panther_readonly user AWS Secret

  • ARN for the panther_admin user AWS Secret

Your Panther POC will re-deploy Panther with these settings to enable Snowflake.

CloudPrem Users

Customers running Panther in their own accounts (we call that CloudPrem) need to first deploy the master template doing an initial setup of Panther. After deploying the master template configure the master stack parameters as below:

  • update: SnowflakeAPISecretARN parameter as the ARN of the secret created above for the panther_readonly user.

  • update: SnowflakeAdminAPISecretARN parameter as the ARN of the secret created above for the panther_admin user.

  • update: SnowflakeDestinationClusterARNs parameter as the value of <SNOWFLAKE_IAM_USER> from initial step above.

Execute an update to the Cloudformation stack.

Validation of Snowpipe Processing

Once Panther is configured for Snowflake, you should have five databases:

  • panther_logs

  • panther_rule_matches

  • panther_rule_errors

  • panther_cloudsecurity

  • panther_views

  • pather_stored_procedures

These are the same database names used in AWS Athena and queries should behave similarly.

Assuming you have data being regularly being processed, there should be data in the tables in a few minutes. This depends on your rate of log ingestion.

You can quickly test if the data ingestion is working by running a simple query:

SELECT count(1) AS c FROM panther_views.public.all_logs ;

The configuration can be tested from the Data Explorer. Run some same queries over a table that you know has data (check via Snowflake console).

Rotating Secrets

To rotate secrets, create a NEW user and edit the secret replacing the old user and password with the new user and password. Wait one hour before deleting/disabling the old user in Snowflake.

Source Deployments (Panther internal users only)

Edit your deployments/panther_config.yml.

Update SecretsManagerARN in the panther_config.yml file using the arns of your created secrets.

# Setting this configures SnowflakeAPI allowing the Data Explorer and scheduled queries to
# access data in Snowflake. This is the ARN of a secret in AWS Secrets Manager with the following attributes:
# * account
# * user
# * password
# * host
# * port
# For example:
# SecretsManagerARN: arn:aws:secretsmanager:us-east-2:05060362XXXX:secret:panther-snowflake-readonly-secret-x1CT28
SecretsManagerARN: arn:aws:secretsmanager:eu-central-1:18532453XXXX:secret:panther-snowflake-readonly-secret-Uk9bBw
# Similar to the above, this secret is used by the deployment and source onboarding operations to create/update tables
SecretsManagerAdminARN: arn:aws:secretsmanager:eu-central-1:18532453XXXX:secret:panther-snowflake-admin-secret-aaa9bBw

Add <SNOWFLAKE_IAM_USER> (e.g., arn:aws:iam::34318291XXXX:user/k7m2-s-v2st0722) to the Snowflake configuration:

# Snowflake (https://www.snowflake.com/) Integration
Snowflake:
# List of Snowflake cluster IAM ARNs which will ingest the output of Panther log processing.
# To configure Snowflake, after deployment generate a file with the ops tool `snowpipe`.
# This file should be run in your snowflake cluster to configure Snowpipe and declare the Panther tables.
# For example:
# DestinationClusterARNs:
# - arn:aws:iam::34318291XXXX:user/k8m1-s-v2st0721 # test snowflake cluster
# - arn:aws:iam::34318291XXXX:user/h1h4-s-a2st0111 # production snowflake cluster
DestinationClusterARNs:
- arn:aws:iam::34318291XXXX:user/k7m2-s-v2st0722

Run mage deploy.
