Webhook¶
Wallarmを使用すると、HTTPSプロトコルを介して受信Webhookを受け入れる任意のシステムに即時通知を送信するよう設定できます。
通知フォーマット¶
通知は、統合設定時に選択した形式に応じてJSON ArrayまたはNew Line Delimited JSON (NDJSON)形式で送信されます。通知が送信されるイベントに応じて、JSONオブジェクトのセットが異なります。例：
-

統合の設定¶
-
Wallarm UI → Integrations を開きます。
-
Webhookブロックをクリックするか、Add integrationボタンをクリックしてWebhookを選択します。
-
統合名を入力します。
-
対象Webhook URLを入力します。
-
必要な場合、詳細設定を構成します:
- Request method:
POSTorPUT. By default, POST requests are sent. - Request header and its value if the server requires a non-standard header to execute the request. The number of headers is not limited.
- CA certificate: certificate of CA that signed a server certificate. If CA is publicly trusted, this field is optional. If a server certificate is self-signed, this field is required and must contain a certificate of your own CA that signed a server certificate.
- Verify TLS certificate: this setting allows to disable verification of the specified server certificate. By default, Wallarm verifies whether a server certificate is signed by a publicly trusted CA. We do not recommend disabling the verification of production server certificates. If your server uses a self-signed TLS certificate, you can add a self-signed CA certificate to allow sending requests to this server.
- Request timeout, in seconds: if the server does not respond to the request within the specified time, the request fails. By default: 15 seconds.
- Connection timeout, in seconds: if the connection to the server cannot be established during the specified time, the request fails. By default: 20 seconds.
- Wallarm data format: either a JSON Array (default) or a New Line Delimited JSON (NDJSON).
- Request method:
-
通知をトリガーするイベントタイプを選択します。
利用可能なイベントの詳細:
-
Hits detected except for:
- Experimental hits detected based on the custom regular expression. Non-experimental hits trigger notifications.

- Integration changes (disabled, deleted)
- Application changes (newly created, deleted, name change)
- Errors during regular update of specifications used for rogue API detection or API specification enforcement
- Vulnerabilities detected, all by default or only for the selected risk level(s) - high, medium or low.
- Rules and triggers changed (creating, updating, or deleting the rule or trigger)
- (Requires AASM Enterprise) Security issues detected, all or only for the selected risk level(s):
- Critical risk
- High risk
- Medium risk

Wallarm Cloud IP addresses
To provide Wallarm Cloud access to your system, you may need a list of its public IP addresses:
追加アラートの設定¶
Besides the notifications you have already set up through the integration card, Wallarm triggers allow you to select additional events for notifications:
-
Number of attacks, hits or incidents per time interval (day, hour, etc.) exceeds the set number
What is not counted
- For attacks:
- The experimental attacks based on the custom regular expressions.
- For hits:
- The experimental hits based on the custom regular expressions.
- Hits not saved in the sample.
- For attacks:
-
Changes in API took place
-
IP address was denylisted
-
New rogue API (shadow, orphan, zombie) was detected
-
New user was added to the company account
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.
例：IPアドレスが拒否リストに追加された場合のWebhook URLへの通知¶
IPアドレスが拒否リストに追加された場合、このイベントに関するWebhookがWebhook URLに送信されます。
トリガーをテストするには:
-
Wallarm Console → IP lists → Denylist を開き、IPアドレスを拒否リストに追加します。例えば:
-
次のWebhookがWebhook URLに送信されたことを確認します:
[ { "summary": "[Wallarm] Trigger: New IP address was denylisted", "description": "Notification type: ip_blocked\n\nIP address 1.1.1.1 was denylisted until 2021-06-10 02:27:15 +0300 for the reason Produces many attacks. You can review blocked IP addresses in the \"Denylist\" section of Wallarm Console.\nThis notification was triggered by the \"Notification about denylisted IP\" trigger. The IP is blocked for the application Application #8.\n\nClient: TestCompany\nCloud: EU\n", "details": { "client_name": "TestCompany", "cloud": "EU", "notification_type": "ip_blocked", "trigger_name": "Notification about denylisted IP", "application": "Application #8", "reason": "Produces many attacks", "expire_at": "2021-06-10 02:27:15 +0300", "ip": "1.1.1.1" } } ]- 「Notification about denylisted IP」はトリガー名です
- 「TestCompany」はWallarm Console上の会社アカウント名です
- 「EU」は会社アカウントが登録されているWallarm Cloudです
統合の無効化および削除¶
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.
システムの利用不可および統合パラメータの誤り¶
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.
