Name:AWS ECR Container Scanning Findings Medium id:0b80e2c8-c746-4ddb-89eb-9efd892220cf version:13 date:None author:Patrick Bareiss, Splunk status:production type:Anomaly Description:The following analytic identifies medium-severity findings from AWS Elastic Container Registry (ECR) image scans. It leverages AWS CloudTrail logs, specifically the DescribeImageScanFindings event, to detect vulnerabilities in container images. This activity is significant for a SOC as it highlights potential security risks in containerized applications, which could be exploited if not addressed. If confirmed malicious, these vulnerabilities could lead to unauthorized access, data breaches, or further exploitation within the container environment, compromising the overall security posture.

how_to_implement:You must install splunk AWS add on and Splunk App for AWS. This search works with AWS CloudTrail logs. known_false_positives:No false positives have been identified at this time.
