Securing S3 Against Ransomware with YES3

Learn how to identify and remediate common S3 security misconfigurations that can lead to S3 ransomware vulnerability (and other issues) using Fog Security's YES3 Scanner tool. Explore a pre-configured AWS S3 bucket with intentional security misconfigurations, run security scans to detect issues like disabled public access blocks, inadequate encryption, disabled versioning, and missing logging configurations. Then, implement security best practices by enabling versioning, turning on block public access, and removing public bucket policies. By the end of the lab, you will understand how to assess S3 security posture, address vulnerabilities that could lead to unauthorized access or ransomware attacks, and verify their remediation efforts through follow-up scans.
