list-violation-events

Description

Lists the Device Defender security profile violations discovered during the given time period. You can use filters to limit the results to those alerts issued for a particular security profile, behavior, or thing (device).

Requires permission to access the ListViolationEvents action.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

list-violation-events is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: violationEvents

Options

--start-time (timestamp)

The start time for the alerts to be listed.

--end-time (timestamp)

The end time for the alerts to be listed.

--thing-name (string)

A filter to limit results to those alerts caused by the specified thing.

--security-profile-name (string)

A filter to limit results to those alerts generated by the specified security profile.

--behavior-criteria-type (string)

The criteria for a behavior.

Possible values:

  • STATIC

  • STATISTICAL

  • MACHINE_LEARNING

--list-suppressed-alerts | --no-list-suppressed-alerts (boolean)

A list of all suppressed alerts.

--verification-state (string)

The verification state of the violation (detect alarm).

Possible values:

  • FALSE_POSITIVE

  • BENIGN_POSITIVE

  • TRUE_POSITIVE

  • UNKNOWN

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Output

violationEvents -> (list)

The security profile violation alerts issued for this account during the given time period, potentially filtered by security profile, behavior violated, or thing (device) violating.

(structure)

Information about a Device Defender security profile behavior violation.

violationId -> (string)

The ID of the violation event.

thingName -> (string)

The name of the thing responsible for the violation event.

securityProfileName -> (string)

The name of the security profile whose behavior was violated.

behavior -> (structure)

The behavior that was violated.

name -> (string)

The name you’ve given to the behavior.

metric -> (string)

What is measured by the behavior.

metricDimension -> (structure)

The dimension for a metric in your behavior. For example, using a TOPIC_FILTER dimension, you can narrow down the scope of the metric to only MQTT topics where the name matches the pattern specified in the dimension. This can’t be used with custom metrics.

dimensionName -> (string)

A unique identifier for the dimension.

operator -> (string)

Defines how the dimensionValues of a dimension are interpreted. For example, for dimension type TOPIC_FILTER, the IN operator, a message will be counted only if its topic matches one of the topic filters. With NOT_IN operator, a message will be counted only if it doesn’t match any of the topic filters. The operator is optional: if it’s not provided (is null ), it will be interpreted as IN .

criteria -> (structure)

The criteria that determine if a device is behaving normally in regard to the metric .

comparisonOperator -> (string)

The operator that relates the thing measured (metric ) to the criteria (containing a value or statisticalThreshold ). Valid operators include:

  • string-list : in-set and not-in-set

  • number-list : in-set and not-in-set

  • ip-address-list : in-cidr-set and not-in-cidr-set

  • number : less-than , less-than-equals , greater-than , and greater-than-equals

value -> (structure)

The value to be compared with the metric .

count -> (long)

If the comparisonOperator calls for a numeric value, use this to specify that numeric value to be compared with the metric .

cidrs -> (list)

If the comparisonOperator calls for a set of CIDRs, use this to specify that set to be compared with the metric .

(string)

ports -> (list)

If the comparisonOperator calls for a set of ports, use this to specify that set to be compared with the metric .

(integer)

number -> (double)

The numeral value of a metric.

numbers -> (list)

The numeral values of a metric.

(double)

strings -> (list)

The string values of a metric.

(string)

durationSeconds -> (integer)

Use this to specify the time duration over which the behavior is evaluated, for those criteria that have a time dimension (for example, NUM_MESSAGES_SENT ). For a statisticalThreshhold metric comparison, measurements from all devices are accumulated over this time duration before being used to calculate percentiles, and later, measurements from an individual device are also accumulated over this time duration before being given a percentile rank. Cannot be used with list-based metric datatypes.

consecutiveDatapointsToAlarm -> (integer)

If a device is in violation of the behavior for the specified number of consecutive datapoints, an alarm occurs. If not specified, the default is 1.

consecutiveDatapointsToClear -> (integer)

If an alarm has occurred and the offending device is no longer in violation of the behavior for the specified number of consecutive datapoints, the alarm is cleared. If not specified, the default is 1.

statisticalThreshold -> (structure)

A statistical ranking (percentile)that indicates a threshold value by which a behavior is determined to be in compliance or in violation of the behavior.

statistic -> (string)

The percentile that resolves to a threshold value by which compliance with a behavior is determined. Metrics are collected over the specified period (durationSeconds ) from all reporting devices in your account and statistical ranks are calculated. Then, the measurements from a device are collected over the same period. If the accumulated measurements from the device fall above or below (comparisonOperator ) the value associated with the percentile specified, then the device is considered to be in compliance with the behavior, otherwise a violation occurs.

mlDetectionConfig -> (structure)

The configuration of an ML Detect

confidenceLevel -> (string)

The sensitivity of anomalous behavior evaluation. Can be Low , Medium , or High .

suppressAlerts -> (boolean)

Suppresses alerts.

metricValue -> (structure)

The value of the metric (the measurement).

count -> (long)

If the comparisonOperator calls for a numeric value, use this to specify that numeric value to be compared with the metric .

cidrs -> (list)

If the comparisonOperator calls for a set of CIDRs, use this to specify that set to be compared with the metric .

(string)

ports -> (list)

If the comparisonOperator calls for a set of ports, use this to specify that set to be compared with the metric .

(integer)

number -> (double)

The numeral value of a metric.

numbers -> (list)

The numeral values of a metric.

(double)

strings -> (list)

The string values of a metric.

(string)

violationEventAdditionalInfo -> (structure)

The details of a violation event.

confidenceLevel -> (string)

The sensitivity of anomalous behavior evaluation. Can be Low , Medium , or High .

violationEventType -> (string)

The type of violation event.

verificationState -> (string)

The verification state of the violation (detect alarm).

verificationStateDescription -> (string)

The description of the verification state of the violation.

violationEventTime -> (timestamp)

The time the violation event occurred.

nextToken -> (string)

A token that can be used to retrieve the next set of results, or null if there are no additional results.
