AWS Bedrock Model Invocation Logging Disabled or Modified

Elastic Detection Rules

View Source
Summary
Detects when AWS Bedrock model invocation logging configuration is deleted or overwritten via CloudTrail events for DeleteModelInvocationLoggingConfiguration or PutModelInvocationLoggingConfiguration. Bedrock model invocation logging feeds logs-aws_bedrock.invocation-*, which underpin all Bedrock data-plane detections. Deleting the configuration disables telemetry; overwriting it with Put can redirect logs to an attacker-controlled or unmonitored destination. The rule filters for successful actions from the Bedrock provider (bedrock.amazonaws.com) and inspects the destination parameters to verify ownership/monitoring (S3 bucket/key prefix and CloudWatch log group). This is a high-value defense-evasion technique because it blinds the entire data-plane detection stack. The rule supports rapid detection of tampering and logging misdirection, enabling quick containment and recovery actions.
