Which tool is an open-source runtime security project that integrates with Kubernetes for identifying abnormal behavior and potential security threats?

• A. OpenVAS
• B. Falco
• C. Aqua Security
• D. Twistlock

Answer: (B)

Runtime security for Kubernetes is about watching what runs and how it behaves inside containers in real time, so you can spot abnormal or unauthorized activity as it happens. Falco fits this need as an open-source runtime security project that integrates with Kubernetes by listening to host system calls and Kubernetes audit events to detect unusual actions. It uses a rules engine to codify what looks suspicious, such as a shell being started inside a container, unexpected file access, suspicious network connections, or privilege escalation. When a rule is triggered, Falco emits alerts, enabling rapid response and containment. Being open-source and designed for cloud-native environments, it can be deployed across a Kubernetes cluster (often as a DaemonSet) to monitor all nodes. OpenVAS is a network vulnerability scanner rather than real-time runtime monitoring. Aqua Security and Twistlock (now part of Prisma Cloud) are security platforms with runtime capabilities, but they are commercial solutions, not open-source runtime security projects.
