本文档介绍了如何使用 Google Cloud将 Cloud NGFW 日志导出并注入到 Google Security Operations 中。解析器从 Google Cloud 防火墙日志中提取字段，并将其转换和映射到 UDM。它会处理各种日志字段，包括连接详细信息、威胁信息、规则详细信息和网络信息，并根据 action 和 direction 字段执行数据类型转换、重命名和条件逻辑，以正确填充 UDM 模型。

Pre-GA features might have limited support, and changes to pre-GA features might not be compatible with other pre-GA versions. For more information, see the [Google SecOps Technical Support Service guidelines](https://chronicle.security/legal/technical-support-services-guidelines/) and the [Google SecOps Service Specific Terms](https://chronicle.security/legal/service-terms/).\n\nThis document explains how to export and ingest Cloud NGFW logs into Google Security Operations using Google Cloud. The parser extracts fields from Google Cloud Firewall logs, transforms and maps them to the UDM. It handles various log fields, including connection details, threat information, rule details, and network information, performing data type conversions, renaming, and conditional logic based on the `action` and `direction` fields to populate the UDM model correctly.\n\nBefore you begin\n----------------\n\nEnsure that you have the following prerequisites:\n\n- Google SecOps instance.\n- Cloud NGFW is active and configured in your Google Cloud environment.\n- Privileged access to Google Cloud and appropriate permissions to access Cloud NGFW logs.\n\nCreate a Cloud Storage bucket\n-----------------------------\n\n1. Sign in to the [Google Cloud console](https://console.cloud.google.com/).\n2. Go to the **Cloud Storage Buckets** page.\n\n [Go to Buckets](https://console.cloud.google.com/storage/browser)\n3. Click **Create**.\n\n4. On the **Create a bucket** page, enter your bucket information. After each of the following steps, click **Continue** to proceed to the next step:\n\n 1. In the **Get started** section, do the following:\n\n 1. Enter a unique name that meets the bucket name requirements; for example, **gcp-ngfw-logs**.\n 2. To enable hierarchical namespace, click the expander arrow to expand the **Optimize for file oriented and data-intensive workloads** section, and then select **Enable Hierarchical namespace on this bucket**.\n\n | **Note:** You cannot enable hierarchical namespace on an existing bucket.\n 3. To add a bucket label, click the expander arrow to expand the **Labels** section.\n\n 4. Click **Add label**, and specify a key and a value for your label.\n\n 2. In the **Choose where to store your data** section, do the following:\n\n 1. Select a **Location type**.\n 2. Use the location type menu to select a **Location** where object data within your bucket will be permanently stored.\n\n | **Note:** If you select the **dual-region** location type, you can also choose to enable **turbo replication** by using the relevant checkbox.\n 3. To set up cross-bucket replication, expand the **Set up cross-bucket replication** section.\n\n 3. In the **Choose a storage class for your data** section, either select a **default storage class** for the bucket, or select **Autoclass** for automatic storage class management of your bucket's data.\n\n 4. In the **Choose how to control access to objects** section, select **not** to enforce **public access prevention** , and select an **access control model** for your bucket's objects.\n\n | **Note:** If public access prevention is already enforced by your project's organization policy, the **Prevent public access** checkbox is locked.\n 5. In the **Choose how to protect object data** section, do the following:\n\n 1. Select any of the options under **Data protection** that you want to set for your bucket.\n 2. To choose how your object data will be encrypted, click the expander arrow labeled **Data encryption** , and select a **Data encryption method**.\n5. Click **Create**.\n\n| **Note:** Be sure to provide your Google SecOps service account with permissions to Read or Read \\& Write to the newly created bucket.\n\nConfigure Cloud NGFW logs export\n--------------------------------\n\n1. Sign in to the [Google Cloud console](https://console.cloud.google.com/).\n2. Go to **Logging \\\u003e Log Router**.\n3. Click **Create Sink**.\n4. Provide the following configuration parameters:\n\n - **Sink Name** : enter a meaningful name; for example, `NGFW-Export-Sink`.\n - **Sink Destination** : select **Google Cloud Storage** and enter the URI for your bucket; for example, `gs://gcp-ngfw-logs`.\n - **Log Filter**:\n\n logName=\"projects/\u003cyour-project-id\u003e/logs/gcp-firewall\"\n\n5. Click **Create**.\n\nConfigure permissions for Cloud Storage\n---------------------------------------\n\n1. Go to **IAM \\& Admin \\\u003e IAM**.\n2. Locate the **Cloud Logging** service account.\n3. Grant the **roles/storage.admin** on the bucket.\n\nSet up feeds\n------------\n\nThere are two different entry points to set up feeds in the\nGoogle SecOps platform:\n\n- **SIEM Settings \\\u003e Feeds \\\u003e Add New**\n- **Content Hub \\\u003e Content Packs \\\u003e Get Started**\n\nHow to set up the Google Cloud NGFW Enterprise feed\n---------------------------------------------------\n\n1. Click the **Google Cloud Compute platform** pack.\n2. Locate the **GCP NGFW Enterprise** log type.\n3. Click **Next**.\n4. Specify values for the following fields:\n\n - **Source Type**: Google Cloud Storage V2\n - **Storage Bucket URI** : Google Cloud storage bucket URL; for example, `gs://gcp-ngfw-logs`.\n - **Source deletion options**: select the deletion option according to your preference.\n\n | **Note:** If you select the `Delete transferred files` or `Delete transferred files and empty directories` option, make sure that you granted appropriate permissions to the service account.\n - **Maximum file age**: Include files modified within the last number of days. Default is 180 days.\n\n5. Click **Get a Service Account** next to the **Chronicle Service Account** field.\n\n **Advanced options**\n - **Feed Name**: A prepopulated value that identifies the feed.\n - **Asset Namespace** : [Namespace associated with the feed](/chronicle/docs/investigation/asset-namespaces).\n - **Ingestion Labels**: Labels applied to all events from this feed.\n6. Click **Create feed**.\n\n| **Note:** The Content Hub is not available on the SIEM standalone platform. To upgrade, contact your Google SecOps representative.\n\nFor more information about configuring multiple feeds for different log types within this product family, see [Configure feeds by product](/chronicle/docs/ingestion/ingestion-entities/configure-multiple-feeds).\n\nUDM Mapping Table\n-----------------\n\n**Need more help?** [Get answers from Community members and Google SecOps professionals.](https://security.googlecloudcommunity.com/google-security-operations-2)"]]
