Container Security Misconfigurations

Overview

The Container Security Misconfigurations widget provides real-time visibility into security configuration issues detected in container images and their Dockerfiles. This widget helps Security Operations (SecOps) and Platform Engineering teams identify and remediate potential security risks arising from container misconfigurations before they can be exploited.

Value for IT and Security Engineers

Security Perspective

  • Configuration Risk Assessment: Enables SecOps engineers to identify insecure container configurations that could lead to security breaches.

  • Compliance Validation: Helps ensure container configurations align with security best practices and compliance requirements.

  • Security Baseline: Supports establishing and maintaining secure container configuration baselines.

Operational Perspective

  • Build Security: Helps platform teams identify and fix security issues in Dockerfile configurations.

  • Runtime Protection: Highlights misconfigurations that could impact container runtime security.

  • Best Practices: Facilitates implementation of container security best practices across the organization.

Common Misconfigurations

  1. Privilege Escalation Risks

    • Running containers as root

    • Excessive capabilities

    • Unrestricted security contexts

  2. Resource Management Issues

    • Missing resource limits

    • Unbounded CPU/memory usage

    • Lack of quotas

  3. Network Security Concerns

    • Exposed sensitive ports

    • Insecure network policies

    • Unrestricted host network access

  4. Storage and Volume Risks

    • Unsafe mount configurations

    • Sensitive host path mounts

    • Writable root filesystems

  5. Security Feature Gaps

    • Disabled SELinux/AppArmor

    • Missing security contexts

    • Inadequate isolation

Best Practices

Configuration Security

  • Implement principle of least privilege

  • Use non-root users

  • Enable security features (SELinux, AppArmor)

  • Configure appropriate security contexts

Resource Management

  • Set resource limits and requests

  • Implement resource quotas

  • Configure memory/CPU constraints

Network Security

  • Implement network policies

  • Restrict port exposure

  • Configure service meshes

Build Security

  • Use multi-stage builds

  • Minimize base image size

  • Follow Dockerfile best practices

Monitoring and Compliance

  • Regular configuration audits

  • Automated security scanning

  • CIS benchmark compliance
