Understanding and Hardening Linux Containers

• The "War and Peace" of container security

Security Assurance Requirements for Linux Application Container Deployments

• Department of commerce guidance on container security

Dramatically Reducing Software Vulnerabilities

• NIST guidance on reducing software vulnerabilities

CoreOS Clair

• A more polished presentation of Clair at CoreOS Fest 2016

OpenSCAP Container Compliance

• Utility for aiding in compliance checks against a container

Actuary

• Automated security profiling for Docker image
• drydock - Inspired by docker-bench-security with the ability to apply custom security profiles
• Docker bench security - One of the first security linting utility for Docker

Buildah

• Introduction
• Docker image building framework

Packer

• Packer builds Docker containers without the use of Dockerfiles. By not using Dockerfiles, Packer is able to provision containers with portable scripts or configuration management systems that are not tied to Docker in any way. It also has a simple mental model: you provision containers much the same way you provision a normal virtualized or dedicated server.

LinuxKit

• A toolkit for building custom minimal, immutable Linux distributions

Grafeas

• An open-source API to audit and govern your software supply chain

Atomic Reactor

• Python library that extends docker build. It's part of the RedHat Atomic project so its rather opinionated

Containers Internals Lab

• A series of exercises that provide a deep dive into the internals of containers. Also has a good SELinux training component

Anchore

• Free image scanning service with a commercial offering similar to Docker Cloud

Alpine CVE Check

• Specialized CVE scanner

Protect Your Docker Containers Against Shellshock

• Most base images have patched out Shellshock, but its still a good exercise for thinking about how to mitigate similar attacks in the future

Banyan Collector: A framework to peek inside containers

• Framework for peering inside docker images. Useful for rolling your own image scanning system

Commercial solutions

• Project Atomic - RedHat's complete container solution with strong built-in security
• Black Duck Software
• Docker Cloud - Continuous scanning of images along with a trust mechanism
• Tenable - Includes FlawCheck
• GrSecurity - A collection of image hardening tools
• Aqua - Full lifecycle container security management platform
• LayeredInsight - Continuous container scanning and auditing
