Streaming del registro de auditoría de su empresa

About audit log streaming

To help protect your intellectual property and maintain compliance for your company, you can use streaming to keep copies of your audit log data. The audit log details events such as changes to settings and access, user membership, app permissions, and more. If you stream audit log data, you can take advantage of the following benefits.

Data exploration. You can examine streamed events using your preferred tool for querying large quantities of data. The stream contains both audit events and Git events across the entire enterprise account.
Data continuity. You can pause the stream for up to seven days without losing any audit data.
Data retention. You can keep your exported audit logs and Git events data as long as you need to.

Enterprise owners can set up, pause, or delete a stream at any time. The stream exports audit and Git events data for all of the organizations in your enterprise, for activity from the time the stream is enabled onwards.

All streamed audit logs are sent as compressed JSON files. The filename format is inYYYY/MM/HH/MM/<uuid>.json.gz.

Note: GitHub uses an at-least-once delivery method. Due to certain network or system issues, some events may be duplicated.

Events that appear in audit log streams

You can review the specific events that appear in streamed audit logs. For more information, see the following articles.

Setting up audit log streaming

You set up the audit log stream on GitHub Enterprise Cloud by following the instructions for your provider.

Amazon S3
Azure Blob Storage
Azure Event Hubs
Datadog
Google Cloud Storage
Splunk

Setting up streaming to Amazon S3

You can set up streaming to S3 with access keys or, to avoid storing long-lived secrets in GitHub Enterprise Cloud, with OpenID Connect (OIDC).

Setting up streaming to S3 with access keys

To set up audit log streaming from GitHub you will need:

Your AWS access key ID
Your AWS secret key

For information on creating or accessing your access key ID and secret key, see Understanding and getting your AWS credentials in the AWS documentation.

In AWS, create a bucket, and block public access to the bucket. For more information, see Creating, configuring, and working with Amazon S3 buckets in the AWS documentation.

In AWS, create a policy that allows GitHub to write to the bucket by copying the following JSON and replacing EXAMPLE-BUCKET with the name of your bucket. GitHub requires only the permissions in this JSON.

{
   "Version": "2012-10-17",
   "Statement": [
      {
         "Sid": "VisualEditor0",
         "Effect": "Allow",
         "Action": [
            "s3:PutObject"
         ],
         "Resource": "arn:aws:s3:::EXAMPLE-BUCKET/*"
     }
   ]
}

For more information, see Creating IAM policies in the AWS documentation.

On the configuration page, enter:
- The domain on which the application you want to stream to is hosted.
  
  If you're using Splunk Cloud, Domain should be http-inputs-<host>, where host is the domain you use in Splunk Cloud. For example, http-inputs-mycompany.splunkcloud.com.
  
  If you're using the free trial version of Splunk Cloud, Domain should be inputs.<host>, where host is the domain you use in Splunk Cloud. For example, inputs.mycompany.splunkcloud.com.
- The port on which the application accepts data.
  
  If you're using Splunk Cloud and haven't changed the port configration, Port should be 443.
  
  If you're using the free trial version of Splunk Cloud, Port should be 8088.
- A token that GitHub can use to authenticate to the third-party application.
Leave the Enable SSL verification check box selected.

Audit logs are always streamed as encrypted data, however, with this option selected, GitHub verifies the SSL certificate of your Splunk instance when delivering events. SSL verification helps ensure that events are delivered to your URL endpoint securely. You can clear the selection of this option, but we recommend you leave SSL verification enabled.
Click Check endpoint to verify that GitHub can connect and write to the Splunk endpoint.
After you have successfully verified the endpoint, click Save.

Pausing audit log streaming

Pausing the stream allows you to perform maintenance on the receiving application without losing audit data. Audit logs are stored for up to seven days on GitHub.com and are then exported when you unpause the stream.

Datadog only accepts logs from up to 18 hours in the past. If you pause a stream to a Datadog endpoint for more than 18 hours, you risk losing logs that Datadog won't accept after you resume streaming.
