SecDevOps containers

In this talk I will speak about main tips for integrating Security into DevOps. I will share my knowledge and experience and help people learn to focus more on DevOps Security. In addition to the so-called best practices, the development of efficient, readable, scalable and secure code, requires the right tools for security development.

These could be the main talking points:
-How to integrate security into iteration and pipeline application development with containers.
-How to secure development environments.
-DevOps security best practices

   ● Increased speed and agility for security
   teams.
   ● Increased or better collaboration and
   communication across teams.
   ● Increased opportunities for automated builds
   and quality assurance testing.
   ● Early identification of vulnerabilities in
   application code.

8. ● 1. Containers are NOT Virtual Machines
   ● 2. Containers are isolated area in the OS kernel
   ● 3. Kubernetes is a Container Orchestration Platform.
   ● 4. Kubernetes abstracts the cloud vendor (AWS,Azure,
   GCP) scalability features.

9. ● Build Small Container Images
   ○ Use Alpine Image as your base Linux OS
   ○ Using distroless images
   ○ Smaller image size reduce the Container
   vulnerabilities.

11. ● Containers inmutability
    ○ Container images follow a unix philosophy
    ○ Container images should be immutable
    ○ RUN rm /usr/bin/apt-* /usr/bin/dpkg*

12. ● Avoid root user
    ○ Create a User account
    ○ Add Runtime software’s based on the User Account.
    ○ Run the App under the user account
    ○ Add Security module SELinux or AppArmour to
    increase the security

13. ● Container Security
    ○ Secure your HOST OS. Containers runs on Host
    Kernel.
    ○ No Runtime software downloads inside the container.
    ○ Declare the software requirements at the build time
    itself.
    ○ Download Docker base images from Authentic site.
    ○ Limit the resource utilization using Container
    orchestrators like Kubernetes.
    ○ Don’t run anything on Super privileged mode.

14. ● Docker hub
    ○ Do you have your own container registry?
    ○ Do you check your Dockerfiles?
    ○ Your pipelines has permissions and access to publish
    in docker hub?
    ○ Do you inspect your Dockerfiles?
    ○ Do you have Docker builds correctly configured?
    ○ Do you control where layers are built?

15. ● Docker Content Trust
    ○ https://docs.docker.com/engine/security/trust/
    content_trust/
    ○ export DOCKER_CONTENT_TRUST =1
    ○ Protection of malicious code in images.
    ○ Protection against repeated attacks.
    ○ Protection against key commitments.

23. ● Kubernetes Security
    ○ Preventing image manipulation and unauthorized
    access
    ○ Deploying Pods without root permissions
    ○ Pod Security Policies
    ○ Secrets management

24. ● Pods Security
    ○ Never access a Pod directly from another Pod.
    ○ Never use :latest tag in the image in the
    production scenario.

25. ● Namespaces
    ○ Group your services/pods traffic rules based on
    specific namespace.
    ○ Handle specific Resource Allocations for a
    Namespace.
    ○ If you have more than a dozen Microservices then it’s
    time to bring in Namespaces.

26. ● Using official images
    ○ Use images provided by a vendor
    ○ Critical vulnerabilities are resolved automatically when
    they are updated.

    ○ A shell that runs inside a container with root
    privileges.
    ○ A process that generates another process with
    unexpected behavior.
    ○ Reading a confidential file, for example the
    etc/shadow
    ○ A process that is using a file that is not a device type
    in the /dev path, indicating a possible rootkit activity.

41. SecDevops Containers
    Security best practices
    ● Do not run containers and pods as root.
    ● Disable capabilities and privileges
    ● One application per container, microservice
    oriented approach.
    ● Use small images

42. ● Training and communication is the key to
    success
    ● DevSecOps is not about only ools but the
    correct tools are necessary.
    ● Follow “Least privilege principle”
