Install Tetragon on Standalone Linux\n\nFor non-Kubernetes Linux hosts, install from the tarball release:\n\n```bash\ncurl -LO https:\u002F\u002Fgithub.com\u002Fcilium\u002Ftetragon\u002Freleases\u002Flatest\u002Fdownload\u002Ftetragon-linux-amd64.tar.gz\ntar xzf tetragon-linux-amd64.tar.gz\nsudo cp tetragon \u002Fusr\u002Flocal\u002Fbin\u002F\nsudo cp tetra \u002Fusr\u002Flocal\u002Fbin\u002F\n\n# Start tetragon daemon\nsudo tetragon --btf \u002Fsys\u002Fkernel\u002Fbtf\u002Fvmlinux &\n\n# Stream events\ntetra getevents -o compact\n```\n\n### 3. Monitor Process Execution (Default)\n\nTetragon generates `process_exec` and `process_exit` events by default without any TracingPolicy:\n\n```bash\n# Stream process events in compact format\ntetra getevents -o compact\n\n# Stream in JSON for SIEM ingestion\ntetra getevents -o json | jq '.process_exec \u002F\u002F .process_exit'\n```\n\nExample `process_exec` JSON event:\n\n```json\n{\n  \"process_exec\": {\n    \"process\": {\n      \"binary\": \"\u002Fusr\u002Fbin\u002Fcurl\",\n      \"arguments\": \"https:\u002F\u002Fmalicious.example.com\u002Fpayload\",\n      \"cwd\": \"\u002Ftmp\",\n      \"uid\": 1000,\n      \"pod\": {\n        \"namespace\": \"default\",\n        \"name\": \"webapp-7b4d9f8c6-x2k9p\"\n      },\n      \"parent\": {\n        \"binary\": \"\u002Fbin\u002Fbash\",\n        \"pid\": 1234\n      }\n    }\n  }\n}\n```\n\n### 4. Author TracingPolicy for File Access Monitoring\n\nCreate a TracingPolicy CRD to monitor access to sensitive files via the `sys_openat` kprobe:\n\n```yaml\n# file-access-monitor.yaml\napiVersion: cilium.io\u002Fv1alpha1\nkind: TracingPolicy\nmetadata:\n  name: monitor-sensitive-file-access\nspec:\n  kprobes:\n    - call: \"fd_install\"\n      syscall: false\n      args:\n        - index: 0\n          type: \"int\"\n        - index: 1\n          type: \"file\"\n      selectors:\n        - matchArgs:\n            - index: 1\n              operator: \"Prefix\"\n              values:\n                - \"\u002Fetc\u002Fshadow\"\n                - \"\u002Fetc\u002Fpasswd\"\n                - \"\u002Fetc\u002Fsudoers\"\n                - \"\u002Froot\u002F.ssh\u002F\"\n                - \"\u002Fetc\u002Fkubernetes\u002Fpki\u002F\"\n          matchActions:\n            - action: Post\n```\n\nApply and observe:\n\n```bash\nkubectl apply -f file-access-monitor.yaml\ntetra getevents -o compact --process-filter \"event_set:PROCESS_KPROBE\"\n```\n\n### 5. Author TracingPolicy for Network Connection Monitoring\n\nMonitor outbound TCP connections using the `tcp_connect` kprobe:\n\n```yaml\n# network-monitor.yaml\napiVersion: cilium.io\u002Fv1alpha1\nkind: TracingPolicy\nmetadata:\n  name: monitor-tcp-connections\nspec:\n  kprobes:\n    - call: \"tcp_connect\"\n      syscall: false\n      args:\n        - index: 0\n          type: \"sock\"\n      selectors:\n        - matchActions:\n            - action: Post\n```\n\n### 6. Author TracingPolicy for Privilege Escalation Detection\n\nDetect setuid\u002Fsetgid calls that may indicate privilege escalation:\n\n```yaml\n# privilege-escalation-detect.yaml\napiVersion: cilium.io\u002Fv1alpha1\nkind: TracingPolicy\nmetadata:\n  name: detect-privilege-escalation\nspec:\n  kprobes:\n    - call: \"__sys_setuid\"\n      syscall: false\n      args:\n        - index: 0\n          type: \"int\"\n      selectors:\n        - matchArgs:\n            - index: 0\n              operator: \"Equal\"\n              values:\n                - \"0\"\n          matchActions:\n            - action: Post\n    - call: \"commit_creds\"\n      syscall: false\n      args:\n        - index: 0\n          type: \"cred\"\n      selectors:\n        - matchActions:\n            - action: Post\n```\n\n### 7. Runtime Enforcement with Sigkill Action\n\nBlock unauthorized binary execution by killing the process in-kernel:\n\n```yaml\n# enforce-binary-allowlist.yaml\napiVersion: cilium.io\u002Fv1alpha1\nkind: TracingPolicy\nmetadata:\n  name: enforce-no-crypto-miners\nspec:\n  kprobes:\n    - call: \"sys_execve\"\n      syscall: true\n      args:\n        - index: 0\n          type: \"string\"\n      selectors:\n        - matchArgs:\n            - index: 0\n              operator: \"Postfix\"\n              values:\n                - \"xmrig\"\n                - \"minerd\"\n                - \"cpuminer\"\n                - \"cryptonight\"\n          matchActions:\n            - action: Sigkill\n```\n\n### 8. Export Events to SIEM\n\nConfigure Tetragon to export JSON events to a file sink for Fluentd\u002FFilebeat\u002FVector ingestion:\n\n```bash\n# Helm values for file export\nhelm upgrade tetragon cilium\u002Ftetragon -n kube-system \\\n  --set tetragon.exportFilename=\u002Fvar\u002Flog\u002Ftetragon\u002Ftetragon.log \\\n  --set tetragon.exportFileMaxSizeMB=100 \\\n  --set tetragon.exportFileMaxBackups=5\n```\n\nThen configure your log shipper (e.g., Filebeat) to tail `\u002Fvar\u002Flog\u002Ftetragon\u002Ftetragon.log` and send to your SIEM.\n\n### 9. Kubernetes-Aware Namespace Filtering\n\nUse `TracingPolicyNamespaced` to scope monitoring to specific namespaces:\n\n```yaml\napiVersion: cilium.io\u002Fv1alpha1\nkind: TracingPolicyNamespaced\nmetadata:\n  name: monitor-production-file-access\n  namespace: production\nspec:\n  kprobes:\n    - call: \"fd_install\"\n      syscall: false\n      args:\n        - index: 0\n          type: \"int\"\n        - index: 1\n          type: \"file\"\n      selectors:\n        - matchArgs:\n            - index: 1\n              operator: \"Prefix\"\n              values:\n                - \"\u002Fetc\u002Fshadow\"\n                - \"\u002Fetc\u002Fpasswd\"\n```\n\n## Examples\n\n### Detect Reverse Shell Connections\n\n```yaml\n# reverse-shell-detect.yaml\napiVersion: cilium.io\u002Fv1alpha1\nkind: TracingPolicy\nmetadata:\n  name: detect-reverse-shells\nspec:\n  kprobes:\n    - call: \"tcp_connect\"\n      syscall: false\n      args:\n        - index: 0\n          type: \"sock\"\n      selectors:\n        - matchBinaries:\n            - operator: \"In\"\n              values:\n                - \"\u002Fbin\u002Fbash\"\n                - \"\u002Fbin\u002Fsh\"\n                - \"\u002Fusr\u002Fbin\u002Fpython3\"\n                - \"\u002Fusr\u002Fbin\u002Fperl\"\n                - \"\u002Fusr\u002Fbin\u002Fnc\"\n                - \"\u002Fusr\u002Fbin\u002Fncat\"\n          matchActions:\n            - action: Post\n```\n\n### Monitor Container Escape Attempts\n\n```yaml\n# container-escape-detect.yaml\napiVersion: cilium.io\u002Fv1alpha1\nkind: TracingPolicy\nmetadata:\n  name: detect-container-escape\nspec:\n  kprobes:\n    - call: \"sys_openat\"\n      syscall: true\n      args:\n        - index: 0\n          type: \"int\"\n        - index: 1\n          type: \"string\"\n      selectors:\n        - matchArgs:\n            - index: 1\n              operator: \"Prefix\"\n              values:\n                - \"\u002Fproc\u002F1\u002Froot\"\n                - \"\u002Fproc\u002F1\u002Fns\"\n                - \"\u002Fsys\u002Fkernel\u002Fsecurity\"\n                - \"\u002Fproc\u002Fsysrq-trigger\"\n          matchActions:\n            - action: Post\n    - call: \"sys_mount\"\n      syscall: true\n      args:\n        - index: 0\n          type: \"string\"\n        - index: 1\n          type: \"string\"\n        - index: 2\n          type: \"string\"\n      selectors:\n        - matchActions:\n            - action: Post\n```\n\n### Full Event Pipeline: Tetragon to Elasticsearch\n\n```bash\n# Use tetra CLI to pipe events through jq into Elasticsearch\ntetra getevents -o json | jq -c 'select(.process_kprobe != null)' | \\\n  while IFS= read -r line; do\n    curl -s -X POST \"http:\u002F\u002Felasticsearch:9200\u002Ftetragon-events\u002F_doc\" \\\n      -H \"Content-Type: application\u002Fjson\" \\\n      -d \"$line\"\n  done\n```\n","# Implementing eBPF Security Monitoring\n\n## When to Use\n\n- When deploying kernel-level runtime security monitoring on Linux hosts or Kubernetes clusters\n- When you need sub-millisecond visibility into process execution, network connections, and file access\n- When traditional userspace monitoring tools introduce unacceptable performance overhead\n- When building detection pipelines that require in-kernel filtering before events reach userspace\n- When enforcing runtime security policies (kill process, send signal) at the kernel level\n\n## Prerequisites\n\n- Linux kernel 5.3+ with BTF (BPF Type Format) support enabled\n- Kubernetes 1.24+ cluster (for Kubernetes deployment) or standalone Linux host\n- Helm 3.x installed (for Kubernetes deployment)\n- `kubectl` configured with cluster access\n- `tetra` CLI installed for local event streaming\n- Python 3.8+ with `requests`, `kubernetes`, `pyyaml` dependencies\n- Root or CAP_BPF\u002FCAP_SYS_ADMIN capabilities for eBPF program loading\n\n## Instructions\n\n### 1.
