Multi-tenancy Isolation

Jan 1, 0001

Definition

Multi-tenancy isolation refers to the practice of ensuring that multiple tenants (users, applications, or organizations) sharing the same computing resources are securely isolated from each other. This isolation prevents unauthorized access and data leakage between tenants, maintaining data privacy and security. Effective multi-tenancy isolation involves implementing strict access controls, resource partitioning, and network segmentation to ensure that each tenant operates independently within a shared environment.

Secure Settings Example

# Kubernetes PodSecurityContext for tenant isolation
apiVersion: v1
kind: Pod
metadata:
  name: secure-tenant-pod
spec:
  securityContext:
    runAsUser: 1000
    runAsGroup: 3000
    fsGroup: 2000
  containers:
  - name: tenant-container
    image: tenant-image:latest
    securityContext:
      allowPrivilegeEscalation: false
      capabilities:
        drop:
        - ALL
      readOnlyRootFilesystem: true

Insecure Settings Example

# Kubernetes PodSecurityContext with weak isolation
apiVersion: v1
kind: Pod
metadata:
  name: insecure-tenant-pod
spec:
  securityContext:
    runAsUser: 0
    runAsGroup: 0
  containers:
  - name: tenant-container
    image: tenant-image:latest
    securityContext:
      allowPrivilegeEscalation: true
      capabilities:
        add:
        - NET_ADMIN
      readOnlyRootFilesystem: false
