Security Principles

This document outlines the core security principles implemented in the Secure CINC Auditor Kubernetes Container Scanning platform.

Overview

Our solution is built on several fundamental security principles that ensure a strong security posture for container scanning operations:

• Least Privilege Access: Using minimal permissions needed for container scanning
• Ephemeral Credentials: Employing short-lived tokens (default 15-minute lifespan)
• Resource Isolation: Restricting access to specific namespaces and resources
• Secure Transport: Ensuring all communications are encrypted
• Defense in Depth: Implementing multiple layers of security controls

Core Security Principles

Each security principle is documented in detail:

• Least Privilege - Implementation of minimal permissions
• Ephemeral Credentials - Using temporary, short-lived tokens
• Resource Isolation - Separating scanning resources
• Secure Transport - Ensuring all communications are encrypted

Security by Design

These principles are integrated into the design of all components and approaches:

1. Service accounts have minimal permissions
2. Roles are scoped to specific containers, not entire namespaces
3. Access is limited to only required verbs ("get", "list", "create" for exec)
4. Tokens are short-lived and automatically expire
5. Namespaces isolate scanning operations
