Microsoft's Kubernetes Threat Matrix: Here's What's Missing
With a fuller picture of the Kubernetes threat matrix, security teams can begin to implement mitigation strategies to protect their cluster from threats.

The MITRE ATT&CK threat matrix is a valuable tool for security professionals to understand the various tactics and techniques employed by adversaries to exploit software and networks, from initial access to impact. The matrix covers the various stages commonly involved in a cyberattack, and the tactics exploited by attackers in each stage. Organizations can use the matrix to understand their attack surface and make sure they cover all their bases.


In April, Microsoft Azure Security Center released a threat matrix based on the MITRE ATT&CK model that identifies tactics and threats unique to environments running in Kubernetes, the most popular container orchestration platform used by cloud-native application builders today.


The Azure Kubernetes matrix adapts and translates the tactics found in the original MITRE ATT&CK framework to the challenges of Kubernetes. For example, in the MITRE ATT&CK matrix, "initial access to the computer" translates to "initial access to the cluster" in the Azure matrix, reflecting the different technology involved in that access. Azure's matrix is a major milestone in capturing the difference between traditional IT security and cloud-native security, and expanding security left and right.


However, platform engineers and security operations teams shouldn't rely solely on Azure's Kubernetes threat matrix. While Azure's matrix allows security teams to think about Kubernetes security along the same lines they do for generic enterprise IT security, there are constructs specific to Kubernetes that do not exist in traditional IT ..
