The AWS S3 Access IP Allowlist rule is designed to ensure that only approved IP addresses are able to access specific S3 buckets. It analyzes access logs from AWS S3 Server Access Logs, checking the 'remoteip' field against a predefined list of allowed IP addresses. If the accessing IP is not on the allowlist, it triggers an alert. The rule is particularly relevant for organizations that need to enforce strict access controls over sensitive data stored in S3 buckets. The rule is currently disabled, and when active, its findings can have a medium severity rating, indicating potential but manageable risks if unapproved access occurs. When accessing the S3 bucket from a non-whitelisted IP, appropriate remediation steps should be taken as outlined in the Runbook, which includes verifying any unauthorized accesses and potentially altering the access policy to enhance security.
