Collect Amazon CloudFront logs

Supported in:

Google SecOps SIEM

Note: This feature is covered by Pre-GA Offerings Terms of the Google Security Operations Service Specific Terms. 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 Security Operations Technical Support Service guidelines and the Google Security Operations Service Specific Terms.

This document describes how you can collect Amazon CloudFront logs by setting up a Google Security Operations feed.

For more information, see Data ingestion to Google Security Operations overview.

An ingestion label identifies the parser which normalizes raw log data to structured UDM format. The information in this document applies to the parser with the AWS_CLOUDFRONT ingestion label.

Before you begin

Ensure that the Amazon S3 bucket is created. For more information, see Create your first S3 bucket.

Configure Amazon CloudFront

1. Sign in to the AWS Management console.
2. Access the Amazon S3 console, and create the Amazon S3 bucket.
3. To enable logging, select On.
4. In the Bucket for logs field, specify the Amazon S3 bucket name.
5. In the Log prefix field, specify an optional prefix.
6. After the logs files are stored in the Amazon S3 bucket, create an SQS queue and attach it with the Amazon S3 bucket.

Identify the endpoints for connectivity

Check the required IAM user and KMS key policies for S3, SQS, and KMS.

Based on the service and region, identify the endpoints for connectivity by referring to the following AWS documentation:

• For information about any logging sources, see AWS Identity and Access Management endpoints and quotas.
• For information about S3 logging sources, see Amazon Simple Storage Service endpoints and quotas.
• For information about SQS logging sources, see Amazon Simple Queue Service endpoints and quotas.

Configure a feed in Google Security Operations to ingest the Amazon CloudFront logs

1. Select SIEM Settings > Feeds.
2. Click Add new.
3. Enter a unique name for the Feed name.
4. Select Amazon S3 or Amazon SQS as the Source type.
5. Select AWS CloudFront as the Log type.
6. Click Next.
7. Google Security Operations supports log collection using access key ID and secret method. To create access key ID and secret, see Configure tool authentication with AWS.
8. Based on the Amazon CloudFront configuration that you created, specify values for the following fields.
   • If you use Amazon S3, specify values for the following fields:
     • Region
     • S3 URI
     • URI is a
     • Source deletion option
   • If you use Amazon SQS, specify values for the following fields:
     • Region
     • Queue name
     • Account number
     • Queue access key ID
     • Queue secret access key
     • Source deletion option
9. Click Next and then click Submit.

To send the Amazon CloudFront logs to the Amazon S3 bucket, see Configure and use standard logs (access logs).

For more information about Google Security Operations feeds, see Google Security Operations feeds documentation. For information about requirements for each feed type, see Feed configuration by type. If you encounter issues when you create feeds, contact Google Security Operations support.

Field mapping reference

This parser extracts fields from AWS CloudFront logs in either SYSLOG or JSON format, normalizing them into the UDM. It uses grok patterns to parse message strings, handles various data transformations (e.g., type conversions, renaming), and enriches the data with additional context like user agent parsing and application protocol identification.

UDM mapping table

Log Field	UDM Mapping	Logic
c-ip	principal.ip	Directly mapped. Also mapped to principal.asset.ip.
c-port	principal.port	Directly mapped.
cs(Cookie)	additional.fields[].key: "cookie" additional.fields[].value.string_value: Directly mapped.	Conditionally mapped if cs(Cookie) is present and agent does not contain "://".
cs(Host)	principal.hostname	Directly mapped. Also mapped to principal.asset.hostname. Used in constructing the target.url if other URL fields are not available.
cs(Referer)	network.http.referral_url	Directly mapped.
cs(User-Agent)	network.http.user_agent	Directly mapped. Also mapped to network.http.parsed_user_agent and parsed into its components if it does not contain "://".
cs-bytes	network.sent_bytes	Directly mapped. Converted to unsigned integer.
cs-method	network.http.method	Directly mapped.
cs-protocol	network.application_protocol	Mapped after converting to uppercase. If the value is not recognized as a standard application protocol and cs-protocol-version contains "HTTP", then network.application_protocol is set to "HTTP".
dport	target.port	Directly mapped. Converted to integer.
edge_location	principal.location.name	Directly mapped.
fle-encrypted-fields	additional.fields[].key: "fle-encrypted-fields" additional.fields[].value.string_value: Directly mapped.	Conditionally mapped if present.
fle-status	additional.fields[].key: "fle-status" additional.fields[].value.string_value: Directly mapped.	Conditionally mapped if present.
host	principal.hostname, principal.asset.hostname	Directly mapped.
id	principal.asset_id	Directly mapped with the prefix "id: ".
ip	target.ip, target.asset.ip	Directly mapped.
log_id	metadata.product_log_id	Directly mapped.
resource	additional.fields[].key: "resource" additional.fields[].value.string_value: Directly mapped.	Conditionally mapped if present.
result_type	additional.fields[].key: "result_type" additional.fields[].value.string_value: Directly mapped.	Conditionally mapped if present.
sc-bytes	network.received_bytes	Directly mapped. Converted to unsigned integer.
sc-content-len	additional.fields[].key: "sc-content-len" additional.fields[].value.string_value: Directly mapped.	Conditionally mapped if present.
sc-content-type	additional.fields[].key: "sc-content-type" additional.fields[].value.string_value: Directly mapped.	Conditionally mapped if present.
sc-status	network.http.response_code	Directly mapped. Converted to integer.
ssl-cipher	network.tls.cipher	Directly mapped.
ssl-protocol	network.tls.version	Directly mapped.
timestamp	metadata.event_timestamp	Parsed and mapped if available. Different formats are supported.
ts	metadata.event_timestamp	Parsed and mapped if available. ISO8601 format is expected.
url	target.url	Directly mapped.
url_back_to_product	metadata.url_back_to_product	Directly mapped.
x-edge-detailed-result-type	additional.fields[].key: "x-edge-detailed-result-type" additional.fields[].value.string_value: Directly mapped.	Conditionally mapped if present.
