Manage IP filters in ECH or Serverless

ECH Serverless

Filtering network traffic, by IP address or CIDR block, is one of the security layers available in Elastic Cloud Enterprise and Elastic Cloud Hosted. It allows you to limit how your deployments can be accessed. IP filters are a type of network security policy.

There are types of filters are available for filtering by IP address or CIDR block:

  • Ingress or inbound IP filters: These restrict access to your deployments from a set of IP addresses or CIDR blocks. These filters are available through the UI.
  • Egress or outbound IP filters: These restrict the set of IP addresses or CIDR blocks accessible from your deployment. These might be used to restrict access to a certain region or service. This feature is currently only available through the Traffic Filtering API. ECH Beta Serverless Unavailable

Follow the step described here to set up ingress or inbound IP filters through the Elastic Cloud Console.

To learn how IP filters work together, and alongside private connection policies, refer to Network security policies in Elastic Cloud.

To learn how to manage IP filters using the Traffic Filtering API, refer to Manage network security through the API.

Note

To learn how to create IP filters for Elastic Cloud Enterprise deployments, refer to Manage IP filters in ECE.

To learn how to create IP filters for self-managed clusters or Elastic Cloud on Kubernetes deployments, refer to Manage IP filtering in ECK and self-managed clusters.

To apply an IP filter to a deployment or project, you must first create an IP filter policy (referred to as "IP filter") at the organization or platform level, and then apply it to your deployment.

You can combine multiple IP address and CIDR block traffic sources into a single IP filter, so we recommend that you group sources according to what they allow, and make sure to label them accordingly. Because multiple IP filters can be applied to a deployment, you can be as granular in your IP filter policies as you require.

To create an IP filter:

  1. Log in to the Elastic Cloud Console.
  2. From any deployment or project on the home page, select Manage.
  3. From the left navigation menu, select Access and security > Network security.

  1. Select Create > IP filter.

  2. Select the resource type that the IP filter will be applied to: either hosted deployments or serverless projects.

  3. Select the cloud provider and region for the IP filter.

    Tip

    IP filters are bound to a single region, and can be assigned only to deployments or projects in the same region. If you want to associate an IP filter with resources in multiple regions, then you have to create the same filter in all the regions you want to apply it to.

  4. Add a meaningful name and description for the IP filter.

  5. Under Access control, select whether the IP filter should be applied to ingress or egress traffic. Currently, only ingress traffic filters are supported.

  6. Add one or more allowed sources using IPv4, or a range of addresses with CIDR.

    Note

    DNS names are not supported in IP filters.

  7. Optional: Under Apply to resources, associate the new filter with one or more deployments or projects. After you associate the IP filter with a deployment or project, it starts filtering traffic.

    Tip

    You can apply multiple policies to a single deployment. For Elastic Cloud Hosted deployments, you can apply both IP filter policies and private connection policies. In case of multiple policies, traffic can match any associated policy to be forwarded to the resource. If none of the policies match, the request is rejected with 403 Forbidden.

    Learn more about how network security policies affect your deployment.

  8. To automatically attach this IP filter to new deployments or projects, select Apply by default.

  9. Click Create.

You can associate an IP filter with your deployment or project from the IP filter's settings, or from your deployment or project's settings. After you associate the IP filter with a deployment or project, it starts filtering traffic.

Tip

You can apply multiple policies to a single deployment. For Elastic Cloud Hosted deployments, you can apply both IP filter policies and private connection policies. In case of multiple policies, traffic can match any associated policy to be forwarded to the resource. If none of the policies match, the request is rejected with 403 Forbidden.

If you want to a specific IP filter from a deployment or project, or delete the IP filter, you’ll need to disconnect it from any associated deployments or projects first. You can do this from the IP filter's settings, or from your deployment or project's settings. To remove an association through the UI:

  1. Find your project on the home page or on the Serverless projects page, then select Manage to access its settings menus.

    On the Hosted deployments page you can narrow your deployments by name, ID, or choose from several other filters. To customize your view, use a combination of filters, or change the format from a grid to a list.

  2. On the Network security page, find the IP filter that you want to disconnect.

  3. Under Actions, click the Delete icon.

  1. Find your deployment on the home page or on the Hosted deployments page, then select Manage to access its settings menus.

    On the Hosted deployments page you can narrow your deployments by name, ID, or choose from several other filters. To customize your view, use a combination of filters, or change the format from a grid to a list.

  2. On the Security page, under Network security, find the IP filter that you want to disconnect.

  3. Under Actions, click the Delete icon.

  1. Log in to the Elastic Cloud Console.
  2. From any deployment or project on the home page, select Manage.
  3. From the left navigation menu, select Access and security > Network security.
  1. Find the IP filter you want to edit, then click the Edit button.
  2. Under Apply to resources, click the x beside the resource that you want to disconnect.
  3. Click Update to save your changes.

You can edit an IP filter's name or description, change the allowed traffic sources, and change the associated resources, and more.

  1. Log in to the Elastic Cloud Console.
  2. From any deployment or project on the home page, select Manage.
  3. From the left navigation menu, select Access and security > Network security.
  1. Find the IP filter you want to edit, then click the Edit button.
  2. Click Update to save your changes.
Tip

You can also edit IP filters from your deployment's Security page or your project's Network security page.

If you need to remove an IP filter, you must first remove any associations with deployments.

To delete an IP filter:

  1. Log in to the Elastic Cloud Console.
  2. From any deployment or project on the home page, select Manage.
  3. From the left navigation menu, select Access and security > Network security.
  1. Find the IP filter you want to edit, then click the Delete button. The icon is inactive if there are deployments or projects associated with the IP filter.
