Options

--behaviors (list)

Specifies the behaviors that, when violated by a device (thing), cause an alert.

(structure)

A Device Defender security profile behavior.

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 .

Note

In the IoT console, you can choose to be sent an alert through Amazon SNS when IoT Device Defender detects that a device is behaving anomalously.

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.

exportMetric -> (boolean)

Value indicates exporting metrics related to the behavior when it is true.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To validate the behaviors parameters for a security profile

The following validate-security-profile-behaviors example validates a well-formed and correct set of behaviors for an AWS IoT Device Defender security profile.

aws iot validate-security-profile-behaviors \
    --behaviors "[{\"name\":\"CellularBandwidth\",\"metric\":\"aws:message-byte-size\",\"criteria\":{\"comparisonOperator\":\"greater-than\",\"value\":{\"count\":128},\"consecutiveDatapointsToAlarm\":1,\"consecutiveDatapointsToClear\":1}},{\"name\":\"Authorization\",\"metric\":\"aws:num-authorization-failures\",\"criteria\":{\"comparisonOperator\":\"greater-than\",\"value\":{\"count\":12},\"durationSeconds\":300,\"consecutiveDatapointsToAlarm\":1,\"consecutiveDatapointsToClear\":1}}]"

Output:

{
    "valid": true,
    "validationErrors": []
}

Example 2: To validate incorrect behaviors parameters for a security profile

The following validate-security-profile-behaviors example validates a set of behaviors that contains an error for an AWS IoT Device Defender security profile.

aws iot validate-security-profile-behaviors \
    --behaviors "[{\"name\":\"CellularBandwidth\",\"metric\":\"aws:message-byte-size\",\"criteria\":{\"comparisonOperator\":\"greater-than\",\"value\":{\"count\":128},\"consecutiveDatapointsToAlarm\":1,\"consecutiveDatapointsToClear\":1}},{\"name\":\"Authorization\",\"metric\":\"aws:num-authorization-failures\",\"criteria\":{\"comparisonOperator\":\"greater-than\",\"value\":{\"count\":12},\"durationSeconds\":300,\"consecutiveDatapointsToAlarm\":100000,\"consecutiveDatapointsToClear\":1}}]"

Output:

{
    "valid": false,
    "validationErrors": [
        {
            "errorMessage": "Behavior Authorization is malformed. consecutiveDatapointsToAlarm 100000 should be in range[1,10]"
        }
    ]
}

For more information, see Detect Commands in the AWS IoT Developer Guide.
