Question: "How do I use CloudTrail to search for actions on a specific resource, such as who deleted an EBS volume on an EC2 instance?"

How do I use AWS CloudTrail to search a given resource for information, such as all event names for a resource, or who deleted an Amazon Elastic Block Store (Amazon EBS) volume or snapshot on an Amazon Elastic Compute Cloud (Amazon EC2) instance?Short descriptionYou can use AWS CloudTrail to log and monitor account activity across your AWS infrastructure. To do so, you must have CloudTrail turned on, and enable logging in the AWS Region where the EC2 resource you want to query resides.ImportantThe rate of lookup requests is limited to one request per second per account. If this limit is exceeded, a throttling error occurs.Events that occurred during a selected time range aren't available for lookup if CloudTrail logging wasn't enabled when the events occurred.

ResolutionNote: If you receive errors when running AWS Command Line Interface (AWS CLI) commands, make sure that you’re using the most recent AWS CLI version.The following examples are run from the AWS CLI. Note that most of these commands use jq.Use yum to install jq in Amazon Linux.yum install jqNote: There are jq install options for other platforms.List all event names for a given resourceThe following example uses an EBS volume ID to get a list of recent events for any API action. Replace the AttributeValue of vol-0f59a355c2example and the --region of us-east-1 with your own values.$ aws cloudtrail lookup-events --lookup-attributes AttributeKey=ResourceName,AttributeValue=vol-0f59a355c2example --query 'Events[].{username:Username,time:EventTime,event:EventName,eventid:EventId,accesskey:AccessKeyId,resource:(Resources[0].ResourceName)}' --output table --region us-east-1Note: CloudTrail might take longer than expected to populate recent calls.The same example can be run using different resource IDs, such as an EBS snapshot. Replace the AttributeValue of snap-0993c0d9a8example and the --region of us-east-1 with your values.$ aws cloudtrail lookup-events --lookup-attributes AttributeKey=ResourceName,AttributeValue=snap-0993c0d9a8example --query 'Events[].{username:Username,time:EventTime,event:EventName,eventid:EventId,accesskey:AccessKeyId,resource:(Resources[0].ResourceName)}' --output table --region us-east-1List events for a specific API action for a given resourceThe following example shows how to get a list of recent events for the DeleteVolume API action for an EBS volume. Replace the AttributeValue of vol-0f59a355c2example with your volume ID.$ aws cloudtrail lookup-events --lookup-attributes AttributeKey=ResourceName,AttributeValue=vol-0f59a355c2example --query 'Events[].{username:Username,time:EventTime,event:EventName,eventid:EventId,accesskey:AccessKeyId,resource:(Resources[0].ResourceName)}' --output json --region us-east-1 | jq -r '.[] | select(.event == "DeleteVolume")'The following is an example of the resulting output:{  "username": "jdoe",  "eventid": "e3ec4051-9999-4e87-9999-9cc72example",  "resource": "vol-0f59a355c2example",  "accesskey": "ASIAXUZVKEUACEXAMPLE",  "time": 1550191014,  "event": "DeleteVolume"}List a specific event name for all resourcesThe following example lists deleted EBS volumes by using the DeleteVolume event name as a filter. Replace --region us-east-1 with your Region.$ aws cloudtrail lookup-events --lookup-attributes AttributeKey=EventName,AttributeValue=DeleteVolume --query 'Events[].{username:Username,time:EventTime,event:EventName,eventid:EventId,accesskey:AccessKeyId,resource:(Resources[0].ResourceName)}' --output table --region us-east-1List terminated EC2 instances for all resourcesThe following example lists recent EC2 TerminateInstances. Replace –region us-east-1 with your Region.$ aws cloudtrail lookup-events --lookup-attributes AttributeKey=EventName,AttributeValue=TerminateInstances --query 'Events[].{username:Username,time:EventTime,event:EventName,eventid:EventId,accesskey:AccessKeyId,resource:(Resources[0].ResourceName)}' --output table --region us-east-1View details for a specific event idAfter you find an event ID, you can view the details about this event. Replace the AttributeValue of 0840b15f-75b5-4082-a194-86e15example with your event ID and replace --region us-east-1 with your Region.$ aws cloudtrail lookup-events --query "Events[0].CloudTrailEvent" --output text --lookup-attribute AttributeKey=EventId,AttributeValue=0840b15f-75b5-4082-a194-86e15example --region us-east-1 | jq -r '.'The following is the example output:{  "eventVersion": "1.05",  "userIdentity": {    "type": "AssumedRole",    "principalId": "AROAJ3THTCWDOKEXAMPLE:jdoe",    "arn": "arn:aws:sts::52570EXAMPLE:assumed-role/Admin/jdoe",    "accountId": "52570example",    "accessKeyId": "ASIAXUZVKEUAKEXAMPLE",    "sessionContext": {      "attributes": {        "mfaAuthenticated": "false",        "creationDate": "2019-02-14T23:55:15Z"      },      "sessionIssuer": {        "type": "Role",        "principalId": "AROAJ3THTCWDOKEXAMPLE",        "arn": "arn:aws:iam::52570EXAMPLE:role/Admin",        "accountId": "52570EXAMPLE",        "userName": "Admin"      }    }  },  "eventTime": "2019-02-15T00:48:05Z",  "eventSource": "ec2.amazonaws.com",  "eventName": "DeleteVolume",  "awsRegion": "us-east-1",  "sourceIPAddress": "999.999.999.999",  "userAgent": "aws-cli/1.16.999 Python/2.7.15 Darwin/17.7.0 botocore/1.12.91",  "requestParameters": {    "volumeId": "vol-0c50d65c6eexample"  },  "responseElements": {    "_return": true  },  "requestID": "a8a43ccd-736d-4b09-ba75-24b9cexample",  "eventID": "0840b15f-75b5-4082-a194-86e15example",  "eventType": "AwsApiCall",  "recipientAccountId": "52570EXAMPLE"}Specify a date rangeYou can use the --start-time and --end-time parameters to specify a date range of events. The listed events occurred after the start-time, as well as up to, and including, the end-time.The default start time is the earliest date that data is available within the last 90 days. The default end time is the time of the event that occurred closest to the current time.If the specified start time is after the specified end time, an InvalidTimeRangeException error is returned.$ aws cloudtrail lookup-events --lookup-attributes AttributeKey=EventName,AttributeValue=DeleteVolume --query 'Events[].{username:Username,time:EventTime,event:EventName,eventid:EventId,accesskey:AccessKeyId,resource:(Resources[0].ResourceName)}' --output table --region us-east-1 --start-time 2019-01-01T13:00Z --end-time 2019-03-01T14:00ZNote: Choose your preferred timestamp from the list at Valid timestamp formats.
