Container & Kubernetes Security Guide
Master container lifecycle and Kubernetes security. Learn Dockerfile hardening, K8s SecurityContext, NetworkPolicies, RBAC, and Falco runtime threat detection.
01. Linux Isolation Primitives & Container Threat Architecture
Understand the core Linux kernel isolation primitives powering container security: Namespaces, cgroups, Capabilities, and Seccomp filtering, along with container escape vectors.
02. Hardened Dockerfiles & Image Security
Master container image security: Multi-stage Dockerfiles, minimal distroless base images, non-root user execution, safe build secret handling, Trivy scanning, Hadolint linter, and Cosign image signing.
03. Kubernetes SecurityContext & Pod Security Standards
Configure Kubernetes SecurityContext settings to enforce non-root execution, drop capabilities, enable Seccomp profiles, enforce read-only filesystems, and comply with the Restricted Pod Security Standard.
04. NetworkPolicies & RBAC Hardening
Implement network microsegmentation using Kubernetes NetworkPolicies (Default Deny) and enforce least-privilege RBAC roles, ServiceAccount token automount controls, and API server auditing.
05. Runtime Threat Detection with Falco
Detect container escapes, shell execution, and unauthorized kernel syscalls in real time using eBPF and CNCF Falco rules.
06. Hands-On Vulnerability Lab: Container Breakout & Hardening
Hands-on vulnerability lab: Audit a vulnerable Kubernetes pod, execute a container breakout exploit to gain host root access, capture Falco alerts, and deploy a hardened remediation.
07. References, Benchmarks & Security Standards
Authoritative benchmarks, security standards, MITRE ATT&CK for Containers mapping, CVE history, and recommended AppSec tooling.
