What it can do on your machine

Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Implementing Runtime Security With Tetragon loads about 2.1k tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 158 tokens; SKILL.md has 396 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~158
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Implementing Runtime Security with Tetragon

Overview

Tetragon is a CNCF project under Cilium that provides flexible Kubernetes-aware security observability and runtime enforcement using eBPF. By operating at the Linux kernel level, Tetragon can monitor and enforce policies on process execution, file access, network connections, and system calls with less than 1% performance overhead -- far more efficient than traditional user-space security agents.

When to Use

  • When deploying or configuring implementing runtime security with tetragon capabilities in your environment
  • When establishing security controls aligned to compliance requirements
  • When building or improving security architecture for this domain
  • When conducting security assessments that require this implementation

Prerequisites

  • Kubernetes cluster v1.24+ with Helm 3.x installed
  • Linux kernel 5.4+ (5.10+ recommended for full eBPF feature support)
  • kubectl access with cluster-admin privileges
  • Familiarity with eBPF concepts and Kubernetes security primitives

Core Concepts

eBPF-Based Security

Tetragon attaches eBPF programs directly to kernel functions, enabling:

  • Process lifecycle tracking: Monitor every process creation, execution, and termination across all pods
  • File integrity monitoring: Detect unauthorized reads/writes to sensitive files
  • Network observability: Track all TCP/UDP connections with full pod context
  • System call filtering: Enforce policies on dangerous syscalls like ptrace, mount, or unshare
TracingPolicy Custom Resources

Tetragon uses TracingPolicy CRDs to define what kernel events to observe and what actions to take:

yaml
apiVersion: cilium.io/v1alpha1
kind: TracingPolicy
metadata:
  name: detect-privilege-escalation
spec:
  kprobes:
    - call: "security_bprm_check"
      syscall: false
      args:
        - index: 0
          type: "linux_binprm"
      selectors:
        - matchBinaries:
            - operator: "In"
              values:
                - "/bin/su"
                - "/usr/bin/sudo"
                - "/usr/bin/passwd"
          matchNamespaces:
            - namespace: Pid
              operator: NotIn
              values:
                - "host_ns"
          matchActions:
            - action: Post
Enforcement Actions

Tetragon can take three types of actions directly in the kernel:

  1. Sigkill: Immediately terminate the offending process
  2. Signal: Send a configurable signal to the process
  3. Override: Override the return value of a kernel function to deny an operation

Practical Implementation

Detecting Container Escape Attempts

Create a TracingPolicy to detect processes attempting to escape container namespaces:

yaml
apiVersion: cilium.io/v1alpha1
kind: TracingPolicy
metadata:
  name: detect-container-escape
spec:
  kprobes:
    - call: "__x64_sys_setns"
      syscall: true
      args:
        - index: 0
          type: "int"
        - index: 1
          type: "int"
      selectors:
        - matchNamespaces:
            - namespace: Pid
              operator: NotIn
              values:
                - "host_ns"
          matchActions:
            - action: Sigkill
Monitoring Sensitive File Access

Detect reads of sensitive credentials:

yaml
apiVersion: cilium.io/v1alpha1
kind: TracingPolicy
metadata:
  name: monitor-sensitive-files
spec:
  kprobes:
    - call: "security_file_open"
      syscall: false
      args:
        - index: 0
          type: "file"
      selectors:
        - matchArgs:
            - index: 0
              operator: "Prefix"
              values:
                - "/etc/shadow"
                - "/etc/kubernetes/pki"
                - "/var/run/secrets/kubernetes.io"
          matchActions:
            - action: Post
Blocking Crypto-Miner Execution

Prevent known crypto-mining binaries from executing:

yaml
apiVersion: cilium.io/v1alpha1
kind: TracingPolicy
metadata:
  name: block-cryptominers
spec:
  kprobes:
    - call: "security_bprm_check"
      syscall: false
      args:
        - index: 0
          type: "linux_binprm"
      selectors:
        - matchBinaries:
            - operator: "In"
              values:
                - "/usr/bin/xmrig"
                - "/tmp/xmrig"
                - "/usr/bin/minerd"
          matchActions:
            - action: Sigkill
Observing Events with Tetra CLI

Stream runtime events in real-time:

bash
# Watch all process execution events
kubectl exec -n kube-system ds/tetragon -c tetragon -- \
  tetra getevents -o compact --process-only

# Filter events for a specific namespace
kubectl exec -n kube-system ds/tetragon -c tetragon -- \
  tetra getevents -o compact --namespace production

# Export events in JSON for SIEM integration
kubectl exec -n kube-system ds/tetragon -c tetragon -- \
  tetra getevents -o json | tee /var/log/tetragon-events.json

Integration with SIEM and Alerting

Export to Elasticsearch
yaml
# tetragon-helm-values.yaml
export:
  stdout:
    enabledCommand: true
    enabledArgs: true
  filenames:
    - /var/log/tetragon/tetragon.log
  elasticsearch:
    enabled: true
    url: "https://elasticsearch.monitoring:9200"
    index: "tetragon-events"
Prometheus Metrics

Tetragon exposes metrics at :2112/metrics:

yaml
apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: tetragon-metrics
  namespace: kube-system
spec:
  selector:
    matchLabels:
      app.kubernetes.io/name: tetragon
