Slack

Slack is a widely used cloud-based team collaboration and messaging platform. It is designed to facilitate communication and collaboration within organizations by providing a centralized space for teams to exchange messages, share files, and integrate with other tools and services. You can set up Wallarm to send notifications to your Slack channel(s). If you want to send notifications to several different Slack channels or accounts, create several Slack integrations.

Setting up integration

  1. Open the Integrations section.

  2. Click the Slack block or click the Add integration button and choose Slack.

  3. Enter an integration name.

  4. Open Webhook settings in Slack and add a new Webhook choosing the channel to post messages to.

  5. Copy the provided Webhook URL and paste the value to the Webhook URL field in Wallarm UI.

  6. Choose event types to trigger notifications.

      • User changes (newly created, deleted, role change)
      • Integration changes (disabled, deleted)
      • Application changes (newly created, deleted, name change)
    • Vulnerabilities detected, all by default or only for the selected risk level(s):
      • High risk
      • Medium risk
      • Low risk
    • Rules and triggers changed (creating, updating, or deleting the rule or trigger)
    • Scope (exposed assets) changed: updates in hosts, services, and domains

  7. Click Test integration to check configuration correctness, availability of the Wallarm Cloud, and the notification format.

    This will send the test notifications with the prefix [Test message]:

    [Test message] [Test partner] Network perimeter has changed

Notification type: new_scope_object_ips

New IP addresses were discovered in the network perimeter:
8.8.8.8

Client: TestCompany

  8. Click Add integration.

Setting up additional alerts

Besides the notifications you have already set up through the integration card, Wallarm triggers allow you to select additional events for notifications:

For condition detailing, you can add one or more filters. As soon, as condition and filters are set, select the integration through which the selected alert should be sent. You can select several integrations simultaneously.

Choosing an integration

Example: Slack notification if 2 or more SQLi hits are detected in one minute

If 2 or more SQLi hits are sent to the protected resource, then a notification about this event will be sent to the Slack channel.

Example of a trigger sending the notification to Slack

To test the trigger:

Send the following requests to the protected resource:

curl 'http://localhost/?id=1%27%20UNION%20SELECT%20username,%20password%20FROM%20users--<script>prompt(1)</script>'
curl 'http://localhost/?id=1%27%20select%20version();'

Open the Slack channel and check that the following notification from the user wallarm received:

[Wallarm] Trigger: The number of detected hits exceeded the threshold

Notification type: attacks_exceeded

The number of detected hits exceeded 1 in 1 minute.
This notification was triggered by the "Notification about SQLi hits" trigger.

Additional trigger’s clauses:
Attack type: SQLi.

View events:
https://my.wallarm.com/attacks?q=attacks&time_from=XXXXXXXXXX&time_to=XXXXXXXXXX

Client: TestCompany
Cloud: EU

  • Notification about SQLi hits is the trigger name

  • TestCompany is the name of your company account in Wallarm Console

  • EU is the Wallarm Cloud where your company account is registered

Example: Slack and email notification if new user is added to the account

If a new user with the Administrator or Analyst role is added to the company account in Wallarm Console, notification about this event will be sent to the email address specified in the integration and to the Slack channel.

Example of a trigger sending the notification to Slack and by email

To test the trigger:

  1. Open the Wallarm Console → Settings → Users and add a new user. For example:

    Added user

  2. Open your email Inbox and check that the following message received:

    Email about new user added

  3. Open the Slack channel and check that the following notification from the user wallarm received:

    [Wallarm] Trigger: New user was added to the company account

Notification type: create_user

A new user John Smith <johnsmith@example.com> with the role Analyst was added to the company account by John Doe <johndoe@example.com>.
This notification was triggered by the "Added user" trigger.

Client: TestCompany
Cloud: EU
    • John Smith and johnsmith@example.com is information about the added user
    • Analyst is the role of the added user
    • John Doe and johndoe@example.com is information about the user who added a new user
    • Added user is the trigger name
    • TestCompany is the name of your company account in Wallarm Console
    • EU is the Wallarm Cloud where your company account is registered

Disabling and deleting an integration

You can delete or temporarily disable the integration. While deleting stops sending notificatioins and completely deletes all configuration, disabling just stops sending notifications which you can at any moment re-enable with the same settings.

If for the integration the System related events are selected to trigger notifications, Wallarm will notify about both of these actions.

System unavailability and incorrect integration parameters

Notifications to the system are sent via requests. If the system is unavailable or integration parameters are configured incorrectly, the error code is returned in the response to the request.

If the system responds to Wallarm request with any code other than 2xx, Wallarm resends the request with the interval until the 2xx code is received:

  • The first cycle intervals: 1, 3, 5, 10, 10 seconds

  • The second cycle intervals: 0, 1, 3, 5, 30 seconds

  • The third cycle intervals: 1, 1, 3, 5, 10, 30 minutes

If the percentage of unsuccessful requests reaches 60% in 12 hours, the integration is automatically disabled. If you receive system notifications, you will get a message about automatically disabled integration.
