Understanding the Threat Landscape for Kubernetes and Containerized Assets

Microsoft Threat Intelligence highlights the evolving security challenges in Kubernetes and containerized environments, emphasizing that the dynamic nature of containers complicates anomaly detection and incident response. A significant concern is the misuse of inactive workload identities, with 51% remaining unused, presenting potential attack vectors. To systematically address these threats, Microsoft has updated its Kubernetes threat matrix and collaborated with MITRE to develop the ATT&CK® for Containers framework. Key threats include compromised accounts, vulnerable or misconfigured images, environment misconfigurations, application-level attacks, and node-level breaches. A notable case involved the threat actor Storm-1977 exploiting weak credentials in the education sector, deploying over 200 containers for cryptomining activities. Microsoft recommends securing the entire container lifecycle—from code and dependencies to CI/CD pipelines and runtime environments—to mitigate these risks.

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...
