**To change a security profile**

The following ``update-security-profile`` example updates both the description and the behaviors for an AWS IoT Device Defender security profile. ::

    aws iot update-security-profile \
        --security-profile-name PossibleIssue \
        --security-profile-description "Check to see if authorization fails 12 times in 5 minutes or if cellular bandwidth exceeds 128"  \
        --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\":\"less-than\",\"value\":{\"count\":12},\"durationSeconds\":300,\"consecutiveDatapointsToAlarm\":1,\"consecutiveDatapointsToClear\":1}}]"

Output::
