Slack Logs

Panther supports pulling logs directly from Slack

Overview

Panther can pull the following Slack logs:

• Audit logs, by querying the Audit Logs API.

  • The Audit Logs API is only available to Slack customers with an Enterprise Grid plan.

• Access logs, by querying the team.accessLogs API.

  • This API is available in all Slack paid plans.

  • Note: Due to Slack's rate limits, Panther pulls only the events where the user or the access location or the access device is new.

• Integration logs, by querying the team.integrationLogs API.

  • This API is available in all Slack paid plans.

Access and integration logs can be ingested through the same Slack log source in Panther, while audit logs must be ingested through a separate Slack log source. However, it is unlikely that you need to ingest all three types of logs, as audit logs are likely to contain all actions represented by access and integrations logs.

Panther will query the API every one minute. In order for Panther to access the Slack API, you need to create a new Slack source on Panther, create a Slack App, and provide the app credentials to Panther.

How to onboard Slack logs to Panther

Create a new Slack Source in Panther

1. In the left-hand navigation bar of your Panther Console, click Configure > Log Sources.

2. Click Create New.

3. Search for "Slack," then click its tile.

4. On the slide-out panel, click Start Setup.

5. On the Configuration screen, enter values for the following fields:

   • Name: Enter a descriptive name for the source e.g., My Slack logs.

   • Select your Slack Plan: Choose from the following options:

     • Enterprise Grid: This option enables the source to receive Slack.AuditLogs.
     • Standard/Plus: This option enables the source to receive Slack.AccessLogs and/or Slack.IntegrationLogs.
6. Click Setup.

7. On the Set Credentials page, Copy the Redirect URL and save it somewhere secure. You will need it in the next steps.

8. Keep this browser window open while you work through the next steps.

Create a new Slack App

Create a Slack app with permissions to pull logs from Slack. For security and availability reasons, we recommend creating a new Slack App that will be used only with Panther.

You can create an app for:

• Audit logs
• Access or Integration logs

How to create a Slack App to pull Audit Logs

Follow the instructions below to create a Slack app that pulls Audit Logs into your Panther account. The Audit Logs API is available to customers with a Slack Enterprise plan only.

If you want to pull in Access or Integration logs, please see the next section: How to create a Slack App to pull Access or Integration logs.

1. Sign in to the Slack workspace belonging to the Enterprise you want to monitor.

   • You must sign in as an owner of the organization.

2. On the screen displaying all the workspaces in your Enterprise, click Launch in Slack on the workspace you want to monitor.

3. Go to Slack apps and click Create New App, then click from scratch.

   • Enter an App Name e.g. Panther monitoring.

   • Select the workspace where you previously signed in.

   
4. Click Create App.

   • The App will be created in the selected workspace and later you will be able to monitor the entire Enterprise organization.

5. In the left sidebar menu, click OAuth & Permissions.

6. Scroll down to the Redirect URLs section.

7. Click Add and enter the Redirect URL that you copied from the Panther Console in the previous section of this documentation.
8. Click Save URLs.

9. Scroll down to the User Token Scopes section. Add the auditlogs:read scope.
10. In the left sidebar, go to Settings > Manage Distribution.

11. Under the section titled "Share Your App with Other Workspaces," enable the following options:

    • Enable Features & Functionality

    • Add OAuth Redirect URLs

    • Remove Hard Coded Information

    • Use HTTPS For Your Features

12. Click Activate Public Distribution.

    • Note: This does not make your Slack App accessible to other organizations. Slack requires this setting to pull audit logs.
13. In the left sidebar, go to Settings > Basic Information.

14. In the App Credentials section, Copy the Client ID and Client Secret.

15. Follow the steps under Finalize Slack Onboarding in Panther to complete this process.

How to create a Slack App to pull Access or Integration Logs

The Access Logs and Integration Logs API is available in all Slack paid plans.

If you want to pull in Audit logs, please see the previous section: How to create a Slack App to pull Audit Logs.

1. Sign in to the Slack workspace you want to monitor.

   • You must sign in as an owner of the organization.

2. On the screen displaying your workspaces, click Launch in Slack on the workspace you want to monitor.

3. Go to Slack apps and click Create New App, then click from scratch.

   • Enter an App Name e.g. Panther monitoring.

   • Select the workspace where you previously signed in.

   
4. Click Create App.

   • The App will be created in the selected workspace.

5. In the left sidebar menu, click OAuth & Permissions.

6. Scroll down to the Redirect URLs section.

7. Click Add and enter the Redirect URL that you copied from the Panther Console in the previous section of this documentation.
8. Click Save URLs.

9. Scroll down to the section titled Scopes > User Token Scopes. Add the admin scope.

10. In the left sidebar, go to Settings > Basic Information.

11. In the App Credentials section, Copy the Client ID and Client Secret.
12. Follow the steps under Finalize Slack Onboarding in Panther to complete this process.

Finalize Slack onboarding in Panther

1. Navigate back to the Panther Console.

2. On the "Set Credentials" page, paste the Client ID from Slack into the Client ID field and the Client Secret from Slack into the Client Secret field.

3. Click Setup.

4. Click Save Source.

5. On the Verify Setup screen, click Grant Access.

   • You will be redirected to a Slack page to install your app.

   • For Audit Logs, make sure you install it to the Enterprise Organization and not to a specific workspace!

6. Click Allow.

7. In the Panther Console, click Setup. You will be directed to a success screen:

   

   • You can optionally enable one or more Detection Packs.
   • The Trigger an alert when no events are processed setting defaults to YES. We recommend leaving this enabled, as you will be alerted if data stops flowing from the log source after a certain period of time. The timeframe is configurable, with a default of 24 hours.

     

Note: The integration will incur limitations if:

• the account of the user that installed the app to the organization is deactivated

• the app was deleted, the access token was revoked, or the app credentials are rotated
