Security policy

As explained in Google Anthos in Action

A security policy is a set of rules governing the protection of systems, applications, and data from unauthorized access or harmful activity.

A security policy is a set of enforceable rules that reduces unauthorized access, service disruption, and exploitable attack paths across systems and workloads. section 7.4 section 13.3.2

In Kubernetes and hybrid environments, effective policies address:

  • Data locality, monitoring, auditing, and compliance requirements for regulated applications. section 7.4
  • Deployment access, workload configuration, and automatic controls that limit service-disrupting changes. section 13.3.2
  • Container identity and privilege, especially whether processes run as root and whether privileged mode is enabled. section 13.6

Restricting container host access

Treat the container user and privileged setting as separate decisions. A root container without privileged mode receives no host permissions, while privileged mode can provide root host access. section 13.6

How Google Anthos in Action covers it

How deep it goes
Explains policy rationale and container privilege consequences, but stops short of an exhaustive organization-specific policy set.
Examples
Uses regulated applications, Kubernetes deployment access, and a root-versus-privileged container permission matrix.
What it assumes
Assumes familiarity with Kubernetes clusters, containers, worker nodes, and workload deployment while distinguishing container and host privileges.
What you can do after
Apply it via Kubernetes controls by prioritizing automatic enforcement and restricting container privileges according to organizational requirements.
How it connects
Connects Kubernetes security, container security, privileged containers, root users, data locality, and automatic policy enforcement.
