KubeArmor Explained | Runtime Security in Kubernetes | DevOps Class 5

Welcome to DevOps Class 5!
In today’s session, we explore KubeArmor, a powerful cloud-native runtime security tool used to enforce security policies inside Kubernetes workloads.

This class breaks down what KubeArmor is, how it works, and why it plays a crucial role in modern container security.

🔥 Topics Covered in DevOps Class 5:
✔ What is KubeArmor?

Cloud-native runtime security enforcement

How KubeArmor uses eBPF, Linux Security Modules (LSM), AppArmor & SELinux

Kernel-level protection explained

✔ KubeArmor Architecture

KubeArmor Operator: manages policy lifecycle

KubeArmor Relay: forwards logs & events to monitoring tools

Integration with Grafana, Elastic, SIEM systems

✔ Key Features of KubeArmor

Process execution control (allow/block specific binaries)

File access control (prevent folder/file misuse)

Network enforcement

Zero-exploit approach

Privilege escalation prevention

Malware & supply-chain attack mitigation

Unauthorized command prevention

Faster detection of abnormal syscalls

Real-time security alerts

Reducing PCI-DSS audit time by up to 60%

✔ Real-World Example

Using KubeArmor to stop malicious behavior triggered by Log4Shell-like vulnerabilities, blocking unexpected Java executions, and preventing compromised workloads from escalating privileges.

🎯 Why This Session Matters

Kubernetes workloads are vulnerable without runtime policies.
KubeArmor helps enforce tight access restrictions, detect risky behavior instantly, and protect clusters against real-world threats.

If you're learning DevOps, Cloud Security, or Kubernetes in 2025, understanding runtime security is essential.
