Azure Kubernetes Service (AKS)
• Managed Kubernetes on Microsoft Azure
• Designed to simplify the deployment,
management, and operations of Kubernetes
• Automated upgrades, patches
• High reliability and availability
• Easy and secure cluster scaling
• Self-healing
• API server monitoring
• Control plane at no charge

What is Container Runtime Security?
• Protection for running containers and
application environment
• Analysis of activity - containers, hosts,
network connections, files, etc.
• Detection and prevention of unknown,
unexpected, and unwanted behavior

● Did someone store credentials in
a configmap versus secrets?
● Who is exec’ing into a pod and
modify a file? Where was it
initiated from?
● Are users escalating privileges via
RBAC?

Why Sysdig for Runtime Security?
Depth
○ Open source Falco based detection engine
○ Out of the box, community driven rules
○ Save time with OOB policies or create custom
policies
Breadth
○ Combine data sources - syscalls, audit logs,
kubernetes context
Single policy interface
○ Detect threats across containers, hosts,
Kubernetes/AKS
○ Manage ‘Policy as code’
Secure containers, Kubernetes and cloud services

Runtime Security for Payment Processing
▸ Difficulty scaling visibility
across cloud environments
▸ No way to effectively police
and audit activity
▸ Proving PCI compliance
Challenge
▸ SaaS-based security and
monitoring with Sysdig
▸ Automated runtime analysis
& intrusion detection
▸ Activity auditing from syscall
data & K8s audit logs
Solution
▸ Achieved results in minutes
with fast onboarding
▸ Improved communication
between DevOps & security
▸ Simplified achieving PCI
compliance
▸ Reduced operational
overhead by 50%
Results
