1. A DEVOPS STATE OF MIND: CONTINUOUS SECURITY WITH KUBERNETES Chris Van Tuin
 Chief Technologist, NA West @chrisvantuin cvantuin@redhat.com https://speakerdeck.com/cvantuin/devopsdays-amsterdam-2019-continuous-security-with-kubernetes
2. ENABLING INNOVATION, WHILE EXECUTING AT SCALE Static &
 Planned Dynamic & 
 Policy Driven Execution Innovation Innovation Execution Old New
3. THE WORLD IS AUTOMATING Those who succeed in automation will win
4. DEV QA OPS THE AVERAGE ENTERPRISE 
 DOES DEPLOYMENTS EVERY 6 TO 9 MONTHS. Walled off people, walled off processes, walled off technologies with surprisingly little to no automation
5. I.T. MUST EVOLVE & KEEP UP

14. CONTAINERS ENABLE DEVSECOPS
15. CONTAINERS Software packaging concept that typically includes an application and all of its runtime dependencies CONTAINER CONTAINER APP LIBS HOST OS SERVER APP LIBS DEVSECOPS BENEFITS • Security: bare minimum image, reduce attack surface • Agility: lightweight, quick deployment • Quality: self contained, immutable, no environment diffs • Portability: build once, deploy anywhere
16. https://medium.com/@bibryam/cloud-native-container-design-principles-144ceaa98dba CLOUD NATIVE CONTAINER DESIGN PRINCIPLES: Build Time Does one thing well Built with dependencies, depends on Linux kernel Build once, deploy anywhere Single Concern Principle Self Containment Principle Image Immutability Principle
17. Process Dispensability Principle CLOUD NATIVE CONTAINER DESIGN PRINCIPLES: Runtime Ephemeral - short lived, replaceable Read & react to events APIs to obeserver & manage Resource requirements defined and restricted High Observability Principle Lifecycle Conformance Principle Runtime Confinement Principle
18. Image Format Distribution Spec Runtime Spec
19. DEVSECOPS AT SCALE

34. • Treat build file as a Blueprint • Don’t login to build/configure • Version control build file • Be explicit with versions, not latest • Always list registry pulling FROM • Each Run creates a new layer • Specify USER, default is root • Sign and validate images BUILD FILE BEST PRACTICES FROM registry.redhat.com/rhel7 RUN groupadd -g 999 appuser && \ useradd -r -u 999 -g appuser appuser USER appuser CMD echo “Hello” Build file

73. NETWORKING
74. Kubernetes 
 Logical Network Model NETWORK SECURITY • Kubernetes uses a flat SDN model • All pods get IP from same CIDR • And live on same logical network • Assumes all nodes communicate
 Traditional 
 Physical Network Model • Each layer represents a Zone with
 increased trust - DMZ > App > DB,
 interzone flow generally one direction • Intrazone traffic generally unrestricted
75. NETWORK SECURITY MODELS Co-Existence Approaches One Cluster Multiple Zones Kubernete Cluster Physical Compute 
 isolation based on 
 Network Zones Kubernete Cluster One Cluster Per Zone Kubernete Cluster B Kubernete Cluster A Kubernetes Cluster B C D https://blog.openshift.com/openshift-and-network-security-zones-coexistence-approaches/
76. Network Namespace 
 provides resource isolation NETWORK ISOLATION Multi-Environment Multi-Tenant
77. NETWORK POLICY example: 
 all pods in namespace ‘project-a’ allow traffic 
 from any other pods in the same namespace.”
