Forensic Analysis of Container Drift in Cloud Environments

Alex John’s article explores container drift, the unauthorized modification of a container’s filesystem, which threatens immutability and may signal security breaches. He highlights forensic tools like Docker Forensics Toolkit and Kube Forensics but notes their limitations in detecting drift. Focusing on OverlayFS, he explains how changes occur in the writable "upper" layer. He recommends using docker diff or custom scripts to track modifications. Enhancing tools with drift detection can improve forensic investigations, helping security teams identify and mitigate unauthorized changes in container environments.

OWASP SAMM Skills Framework Enhances Software Security Roles

The OWASP SAMM Skills Framework, introduced on February 9, 2025, is a new initiative donated by Siemens to enhance software security practices within organizations. This framework assigns specific responsibilities to SAMM (Software Assurance Maturity Model) streams, clarifying which roles are involved in advancing each stream. It provides guidance on the necessary skills and training for each role, aligning SAMM-related activities with appropriate stakeholders and their required competencies. This alignment helps organizations identify the right personnel and visualize shared responsibilities, ensuring a structured approach to secure product development. Implementing the OWASP SAMM Skills Framework involves several key steps. Organizations must first map responsibilities to roles, ensuring each task is assigned to the right individual. Next, they must evaluate and align stakeholders with specific SAMM streams, validating that those assigned understand and accept their roles in advanci...
