Cyber Security Engineer

Requirements

Required tools:

python3 (>= 3.8)

openclaw CLI (installed via npm during bootstrap, or pre-installed)

npm (only needed for bootstrap if openclaw is not already installed)

One of lsof, ss, or netstat for port/egress checks

stat, readlink (standard on macOS/Linux, used by the runtime hook installer)

Env vars (all optional, documented for configuration):

OPENCLAW_REQUIRE_POLICY_FILES — set to 1 to block privileged execution when policy files are missing

OPENCLAW_REQUIRE_SESSION_ID — set to 1 to require a task session id for each privileged action

OPENCLAW_TASK_SESSION_ID — per-task session id (used when OPENCLAW_REQUIRE_SESSION_ID=1)

OPENCLAW_APPROVAL_TOKEN — if set, requires this token during the approval step

OPENCLAW_UNTRUSTED_SOURCE — set to 1 to flag the current content source as untrusted

OPENCLAW_VIOLATION_NOTIFY_CMD — absolute path to a notifier binary (must also be allowlisted)

OPENCLAW_VIOLATION_NOTIFY_ALLOWLIST — JSON array of allowed argv arrays, or comma-separated absolute paths

OPENCLAW_REAL_SUDO — override path to the real sudo binary (used by the runtime hook shim)

OPENCLAW_PYTHON3 — override path to python3 (used by the runtime hook shim)

OPENCLAW_CYBER_SKILL_DIR — override path to the skill directory (used by the runtime hook shim)

OPENCLAW_ALLOW_NONINTERACTIVE_SUDO — set to 1 to allow non-interactive sudo through the shim (default: blocked)

OPENCLAW_PRIV_REASON — human-readable reason passed to the guarded execution wrapper

OPENCLAW_VIOLATION_NOTIFY_STATE — override path to the notification state file

OPENCLAW_SKIP_PLIST_CONFIRM — set to 1 to skip the interactive confirmation before modifying the macOS LaunchAgent plist

Policy files (admin reviewed):

~/.openclaw/security/approved_ports.json

~/.openclaw/security/command-policy.json

~/.openclaw/security/egress_allowlist.json

~/.openclaw/security/prompt-policy.json

Implement these controls in every security-sensitive task:

1. Keep default execution in normal (non-root) mode. 2. Request explicit user approval before any elevated command. 3. Scope elevation to the minimum command set required for the active task. 4. Drop elevated state immediately after the privileged command completes. 5. Expire elevated state after 30 idle minutes and require re-approval. 6. Monitor listening network ports and flag insecure or unapproved exposure. 7. Monitor outbound connections and flag destinations not in the egress allowlist. 8. If no approved baseline exists, generate one with python3 scripts/generate_approved_ports.py, then review and prune. 9. Benchmark controls against ISO 27001 and NIST and report violations with mitigations.

Runtime Hook (sudo shim)

The script scripts/install-openclaw-runtime-hook.sh installs an opt-in sudo shim at ~/.openclaw/bin/sudo. This shim shadows the system sudo binary by prepending ~/.openclaw/bin to PATH in the OpenClaw gateway process.

What it does:

Intercepts sudo invocations and routes them through guarded_privileged_exec.py

Requires explicit interactive user approval before running any privileged command

Enforces command policy allow/deny rules, audit logging, and a 30-minute idle timeout

Blocks non-interactive sudo by default (prevents automated abuse)

Passes through harmless flags (-h, --version, -k, -l) directly to real sudo

What it does NOT do:

It does not replace or modify the system sudo binary

It does not grant itself any elevated permissions

It only affects processes whose PATH includes ~/.openclaw/bin before /usr/bin

Opt-in: The hook is not installed by default. To enable it, run bootstrap with ENFORCE_PRIVILEGED_EXEC=1. On macOS, the installer will prompt for confirmation before modifying the gateway LaunchAgent plist. The shim can be removed at any time by deleting ~/.openclaw/bin/sudo.

File Writes

This skill writes only to ~/.openclaw/ and the assessments/ directory inside the skill folder. No files are written outside these two trees.

Under ~/.openclaw/ (user config/state):

~/.openclaw/security/approved_ports.json — generated port baseline (by generate_approved_ports.py)

~/.openclaw/security/root-session-state.json — elevated session state (by root_session_guard.py)

~/.openclaw/security/privileged-audit.jsonl — append-only audit log (by audit_logger.py)

~/.openclaw/security/violation-notify-state.json — notification diff state (by notify_on_violation.py)

~/.openclaw/bin/sudo — opt-in sudo shim (by install-openclaw-runtime-hook.sh, see Runtime Hook section)

~/.openclaw/logs/cyber-security-engineer-auto.log — auto-cycle run log (by auto_invoke_cycle.sh)

Under assessments/ (inside skill directory):

assessments/openclaw-assessment.json — compliance check results

assessments/compliance-summary.json — structured summary for tools/integrations

assessments/compliance-dashboard.html — human-readable report page

assessments/port-monitor-latest.json — latest open-port scan output

assessments/egress-monitor-latest.json — latest outbound connection scan output

Temporary files:

A short-lived temp file via tempfile.NamedTemporaryFile (by generate_approved_ports.py) — auto-cleaned

No files are written to /usr/, /etc/, or any system directory.

Non-Goals (Web Browsing)

Do not use web browsing / web search as part of this skill. Keep assessments and recommendations based on local host/OpenClaw state and the bundled references in this skill.

Behavior

Never keep root/elevated access open between unrelated tasks.

Never execute root commands without an explicit approval step in the current flow.

Enforce command allow/deny policy when configured.

Require confirmation when untrusted content sources are detected (OPENCLAW_UNTRUSTED_SOURCE=1 + prompt policy).

Enforce task session id scoping when configured (OPENCLAW_REQUIRE_SESSION_ID=1).

If timeout is exceeded, force session expiration and approval renewal.

Log privileged actions to ~/.openclaw/security/privileged-audit.jsonl (best-effort).

Flag listening ports not present in the approved baseline and recommend secure alternatives for insecure ports.

Flag outbound destinations not present in the egress allowlist.

Output Contract

When reporting status, include:

The specific check_id(s) affected, status, risk, and concise evidence.

Concrete mitigations (what to change, where) and any owners/due dates if present.

For network findings: port, bind address, process/service, and why it is flagged (unapproved/insecure/public).
