SIG Auth Charter

This charter adheres to the conventions described in the Kubernetes Charter README and uses the Roles and Organization Management outlined in sig-governance.

Scope

SIG Auth is responsible for the design, implementation, and maintenance of features in Kubernetes that control and protect access to the API and other core components. This includes authentication and authorization, but also encompasses features like auditing and some security policy (see below).

In scope

Link to SIG section in sigs.yaml

Code, Binaries and Services

  • Kubernetes authentication, authorization, audit and security policy features. Examples include:
    • Authentication, authorization and audit interfaces and extension points
    • Authentication implementations (service accounts, OIDC, authenticating proxy, webhook, ...)
    • Authorizer implementations (RBAC + default policy, Node + default policy, webhook, ...)
    • Security-related admission plugins (NodeRestriction, ServiceAccount, PodSecurityPolicy, ImagePolicy, etc)
  • The mechanisms to protect confidentiality/integrity of API data. Examples include:
    • Capability for encryption at rest
    • Capability for secure communication between components
    • Ensuring users and components can operate with appropriately scoped permissions

Cross-cutting and Externally Facing Processes

  • Consult with other SIGs and the community on how to apply mechanisms owned by SIG Auth. Examples include:
    • Review privilege escalation implications of feature and API designs
    • Core component authentication & authorization (apiserver, kubelet, controller-manager, and scheduler)
    • Local-storage volume deployment authentication
    • Cloud provider authorization policy
    • Container runtime streaming (exec/attach/port-forward) authentication
    • Best practices for hardening add-ons or other external integrations

Out of scope

  • Reporting of specific vulnerabilities in Kubernetes. Please report using these instructions: https://kubernetes.io/security/
  • General security discussion. Examples of topics that are out of scope for SIG-auth include:
    • Protection of volume data, container ephemeral data, and other non-API data (prefer: sig-storage and sig-node)
    • Container isolation (prefer: sig-node and sig-networking)
    • Bug bounty (prefer: product security committee)
    • Resource quota (prefer: sig-scheduling)
    • Resource availability / DOS protection (prefer: sig-apimachinery, sig-network, sig-node)

Roles and Organization Management

This sig follows adheres to the Roles and Organization Management outlined in sig-governance and opts-in to updates and modifications to sig-governance.

Subproject Creation

SIG Auth delegates subproject approval to Technical Leads. See Subproject creation - Option 1.
