Juniper

The CrowdSec Juniper integration connects CrowdSec's hosted blocklist endpoint to your Juniper router.
Juniper calls this feature Security Dynamic Address feeds, which allow you to import and automatically update IP address lists from external feed servers.

Ensure your Juniper device supports Security Dynamic Address feeds.
The vendor documentation is available in the References section below.

Create a Juniper Integration Endpoint

1- Create an integration

Step 1 — Create an integration in the CrowdSec Console

In your CrowdSec Console account, navigate to the Blocklist tab in the top menu bar, then select the Integrations sub-menu. Choose the integration type you need, then click Connect.

If you don't have a CrowdSec Console account, sign up here. On mobile, use the menu icon in the top-right corner, tap Blocklist, then Integrations.

2- Remediation Component

Step 2 — Fill in integration details

Name the integration (must be unique to your account) Optionally, add a description and tags to help you identify it later. Then click Create.

3- Save your credentials

Step 3 — Copy your credentials

The credentials shown next are displayed only once. Copy them before closing this screen. If you lose your credentials, you can regenerate them via Configure → Regenerate Credentials on the integration page.

With this HTTPS endpoint and Basic Auth credentials, you can verify the endpoint with any HTTP client, for example:

curl -u 'usr:pass' https://admin.api.crowdsec.net/v1/integrations/$integID/content

4- Subscribe to blocklists

Step 4 — Subscribe to Blocklists

The integration endpoint will serve the deduplicated blocklists it's subscribed to. After creation, a subscription pop-up appears automatically. You can also access it later via the Add Blocklist button.

Select one or more blocklists available for your plan, then click Confirm Subscription. The blocklist name(s) will appear in the integration tile once subscribed.

Configure Juniper

Define the feed server

set security dynamic-address feed-server crowdsec-feed description "CrowdSec Feed"
set security dynamic-address feed-server crowdsec-feed url https://<USERNAME>:<PASSWORD>@admin.api.crowdsec.net

Define the threat feed and update interval

set security dynamic-address feed-server crowdsec-feed feed-name crowdsec-feed description "CrowdSec Feed"
set security dynamic-address feed-server crowdsec-feed feed-name crowdsec-feed path /v1/integrations/<integration_id>/content
set security dynamic-address feed-server crowdsec-feed feed-name crowdsec-feed update-interval 1440 hold-interval 43200

Define the AddressName-to-ThreatFeed mapping

set security dynamic-address address-name crowdsec-feed address-name crowdsec-feed feed-name crowdsec-feed

Review and commit the configuration

show security dynamic-address

The output should look like this:

feed-server crowdsec-feed {
    description "CrowdSec Feed";
    url https://<USERNAME>:<PASSWORD>@admin.api.crowdsec.net;
    feed-name crowdsec-feed {
        description CrowdSec Feed;
        path /v1/integrations/<integration_id>/content;
        update-interval 120;
        hold-interval 43200;
    }
}
address-name crowdsec-feed {
    profile {
        feed-name crowdsec-feed;
    }
}
