Create and manage threat prevention security profiles

This page explains how to create and manage security profiles of the type threat-prevention by using the Google Cloud console or the Google Cloud CLI.

Before you begin

Roles

To get the permissions that you need to create, view, update, or delete security profiles, ask your administrator to grant you the necessary IAM roles on your organization. For more information about granting roles, see Manage access.

Create a threat prevention security profile

When you create a threat prevention security profile (security profile of type threat-prevention), you can specify the name of the security profile as a string or as a unique URL identifier. The unique URL for an organization-scoped security profile can be constructed in the following format:

organization/ORGANIZATION_ID/locations/LOCATION/securityProfiles/SECURITY_PROFILE_NAME

If you use a unique URL identifier for the security profile name, the organization and location of the security profile is already included in the URL identifier. However, if you use only the security profile name, you must specify the organization and location separately. For more information about unique URL identifiers, see security profile specifications.

Console

  1. In the Google Cloud console, go to the Security profiles page.

    Go to Security profiles

  2. In the project selector menu, select your organization.

  3. Select the Security profiles tab.

  4. Click Create profile.

  5. Enter a name in the Name field.

  6. Optional: Enter a description in the Description field.

  7. To create a Cloud Next Generation Firewall Enterprise security profile, in the Purpose section, select Cloud NGFW Enterprise.

  8. To create a threat prevention security profile, in the Type section, select Threat Prevention.

  9. Click Continue.

Optionally, add severity and threat overrides:

  1. Under Severity overrides, click Edit next to the severity level that you want to override.
  2. In the Override action list, select the appropriate action for the severity level.
  3. To add a threat signature override, click Add signature by ID.
  4. In the Signature ID field, enter the threat ID that you want to override. You can view the threat IDs on the threat dashboard.
  5. In the Override action list, select the appropriate action for the threat ID.
  6. Click Create.

gcloud

To create a threat prevention security profile, use the gcloud network-security security-profiles threat-prevention create command:

List threat prevention security profiles

You can list all the threat prevention security profiles in an organization.

Console

  1. In the Google Cloud console, go to the Security profiles page.

    Go to Security profiles

  2. Select the Security profiles tab. The tab shows a list of configured security profiles.

Delete a threat prevention security profile

You can delete a threat prevention security profile by specifying its name, location, and organization. However, if a security profile is referenced by a security profile group, that security profile cannot be deleted.

Console

  1. In the Google Cloud console, go to the Security profiles page.

    Go to Security profiles

  2. Select the Security profiles tab. The tab shows a list of configured security profiles.

  3. Select the threat prevention security profile that you want to delete, and then click Delete.

  4. Click Delete again to confirm.

gcloud

To delete a threat prevention security profile, use the gcloud network-security security-profiles threat-prevention delete command:

gcloud network-security security-profiles threat-prevention delete NAME \
    --organization ORGANIZATION_ID \
    --location LOCATION \
    --project PROJECT_ID

Replace the following:

  • NAME: the name of the threat prevention security profile that you want to delete; you can specify the name as a string or as a unique URL identifier.

Import a threat prevention security profile

You can import a threat prevention security profile (either custom-created or previously exported) from a YAML file. When importing a threat prevention security profile, if a profile with the same name already exists, Cloud NGFW updates the existing profile.

gcloud

To import a threat prevention security profile from a YAML file, use the gcloud beta network-security security-profiles import command:

gcloud beta network-security security-profiles import NAME \
    --organization ORGANIZATION_ID \
    --location LOCATION \
    --source FILE_NAME

Replace the following:

  • NAME: the name of the security profile of type threat-prevention that you want to import; you can specify the name as a string or as a unique URL identifier.

    If you use a unique URL identifier for the NAME flag, you can omit the ORGANIZATION_ID and LOCATION flags.

  • ORGANIZATION_ID: the organization where the threat prevention security profile is created. If you use a unique URL identifier for the NAME flag, you can omit the ORGANIZATION_ID flag.

  • LOCATION: the location of the threat prevention security profile. Location is always set to global. If you use a unique URL identifier for the NAME flag, you can omit the LOCATION flag.

  • FILE_NAME: the path to the YAML file containing the configuration export data for the threat prevention security profile. For example,threat-prevention-sp.yaml.

    The YAML file must not contain any output-only fields. Alternatively, you can omit the source flag to read from the standard input.

Export a threat prevention security profile

You can export a threat prevention security profile to a YAML file. For example, instead of using the user-interface to modify a large security profile, you can use this functionality to export the security profile, modify it quickly, and import it back.

gcloud

To export a threat prevention security profile to a YAML file, use the gcloud beta network-security security-profiles export command:

gcloud beta network-security security-profiles export NAME \
    --organization ORGANIZATION_ID \
    --location LOCATION \
    --destination FILE_NAME

Replace the following:

  • NAME: the name of the security profile of type threat-prevention that you want to export; you can specify the name as a string or as a unique URL identifier.

    If you use a unique URL identifier for the NAME flag, you can omit the ORGANIZATION_ID and LOCATION flags.

  • ORGANIZATION_ID: the organization where the threat prevention security profile is created. If you use a unique URL identifier for the NAME flag, you can omit the ORGANIZATION_ID flag.

  • LOCATION: the location of the threat prevention security profile. Location is always set to global. If you use a unique URL identifier for the NAME flag, you can omit the LOCATION flag.

  • FILE_NAME: the path to the YAML file into which Cloud NGFW will export the configuration for the threat prevention security profile. For example,threat-prevention-sp.yaml.

    The exported configuration data doesn't contain any output-only fields. Alternatively, you can omit the destination flag to write to the standard output.
