detecting-privilege-escalation-in-kubernetes-pods

Detect Kubernetes pod privilege escalation by inspecting pod securityContext fields, capabilities, and host namespace usage using audit scripts. This approach identifies misconfigured containers with elevated access that could enable host compromise.

A Kubernetes pod security context defines privilege and access control settings for containers. It matters because dangerous configurations like privileged mode or allowPrivilegeEscalation can lead to host compromise and broader cluster impact.

Audit Kubernetes pods for dangerous capabilities by running scripts that inspect securityContext fields across pods and init containers. These scripts check for hostPID, hostNetwork, hostIPC, and privileged flags to generate actionable reports.

Falco can monitor Kubernetes pod privilege escalation at runtime using sample rules provided for threat hunting and security investigations. It complements admission controls and audit policies for comprehensive cluster hardening.

Prevent privilege escalation in Kubernetes pods by applying admission controls and audit policy guidance that restrict securityContext fields. This skill provides reference policies alongside Falco rules for comprehensive prevention.

OPA helps with Kubernetes pod security by enforcing admission policies that block privilege escalation misconfigurations. This skill provides audit policy references that work with OPA for cluster hardening and threat prevention.
