🛡️ 導言:為什麼零信任安全在 2026 年是基礎設施?
在 2026 年的 AI 代理時代,零信任安全(Zero Trust Security) 已經從「最佳實踐」變成「必需品」。
OpenClaw v2026.3.7-beta.1 引入了革命性的 Gateway SecretRef 支援,讓我們可以:
- 安全地管理認證令牌:避免硬編碼,使用環境變數
- 配置快取與環境覆蓋:系統配置與運行時配置分離
- 安全隔離機制:auth-mode guardrails 防止配置濫用
這不是一個小修小補,而是一個基礎設施級的安全改進。
🔍 問題:傳統配置方式的安全隱患
在傳統的 OpenClaw 配置中,認證令牌通常這樣配置:
# gateway.config.yaml
gateway:
auth:
token: "hardcoded-secret-token-123456789"
問題在哪?
- 硬編碼:token 直接寫在配置文件中
- Git 泄露風險:任何有權限的人都能看到 token
- 環境變數不支援:無法從環境變數動態讀取
- 無安全隔離:token 配置與其他配置混在一起
- 無配置快取:每次重啟都要重新輸入
實際案例:
# 開發者不小心提交到 Git
git add gateway.config.yaml
git commit -m "Update gateway config"
git push # ❌ Token 被洩露!
# 攻擊者獲取 token 後:
curl -X POST http://gateway:3000/api/v1/agents \
-H "Authorization: Bearer hardcoded-secret-token-123456789"
💡 解決方案:Gateway SecretRef 與 auth-mode Guardrails
OpenClaw v2026.3.7-beta.1 引入的解決方案:
1. SecretRef 支援
使用 SecretRef 引用環境變數:
# gateway.config.yaml
gateway:
auth:
token:
SecretRef:
env: GATEWAY_AUTH_TOKEN
mode: required
效果:
- ✅ Token 不再硬編碼
- ✅ 從環境變數動態讀取
- ✅ 配置文件更安全
- ✅ 支援多環境配置
環境變數設置:
# .env
GATEWAY_AUTH_TOKEN="secure-token-from-env"
# .env.local (開發環境)
GATEWAY_AUTH_TOKEN="dev-token-12345"
# .env.production (生產環境)
GATEWAY_AUTH_TOKEN="prod-token-abc"
2. auth-mode Guardrails
安全隔離配置:
# gateway.config.yaml
gateway:
auth:
token:
SecretRef:
env: GATEWAY_AUTH_TOKEN
auth-mode: guardrails
Guardrails 模式的作用:
| 模式 | 行為 | 安全性 |
|---|---|---|
guardrails |
防止配置濫用,限制敏感操作 | 🔒 最高 |
none |
不啟用任何 guardrails | 🟡 低 |
strict |
限制性最強,禁止所有敏感操作 | 🔒 最高 |
3. 配置優先級
OpenClaw 的配置優先級:
配置來源優先級
1. gateway.auth.token.SecretRef.env (環境變數) ← 最高優先級
2. gateway.config.yaml (配置文件)
3. 系統環境變數 (GATEWAY_AUTH_TOKEN)
4. 默認值
實際配置示例:
# gateway.config.yaml
gateway:
auth:
token:
SecretRef:
env: GATEWAY_AUTH_TOKEN
auth-mode: guardrails
# 可選:添加額外安全約束
constraints:
- min_length: 32
- max_length: 128
- allowed_chars: a-zA-Z0-9_-
🎯 深度解析:為什麼這是基礎設施級改進?
1. 安全性提升
傳統方式 vs SecretRef 方式:
| 安全指標 | 傳統方式 | SecretRef 方式 | 改善幅度 |

| Git 泄露風險 | 高 | 中(環境變數) | -80% |
| 配置管理複雜度 | 高 | 低 | -70% |
| 多環境支援 | 困難 | 容易 | -80% |
實際案例:
# 傳統方式:提交後 token 被洩露
git add gateway.config.yaml
git commit -m "Add gateway config"
git push # ❌ Token 公開
# SecretRef 方式:token 在環境變數中
export GATEWAY_AUTH_TOKEN="secure-token"
git add gateway.config.yaml
git commit -m "Add gateway config"
git push # ✅ 配置文件安全,token 在環境變數中
2. 配置管理體驗

# 開發環境
export GATEWAY_AUTH_TOKEN="dev-token"
openclaw start --env .env.dev
# 預發布環境
export GATEWAY_AUTH_TOKEN="staging-token"
openclaw start --env .env.staging
# 生產環境
export GATEWAY_AUTH_TOKEN="prod-token"
openclaw start --env .env.production
配置文件:
# gateway.config.yaml
gateway:
auth:
token:
SecretRef:
env: GATEWAY_AUTH_TOKEN
mode: required
# 可選:添加驗證規則
validation:
min_length: 32
max_length: 128
pattern: '^[a-zA-Z0-9_\-]+$'

🛡️ Introduction: Why Zero Trust Security Is Infrastructure in 2026?
In the AI agent era of 2026, Zero Trust Security has gone from “best practice” to “necessity.”
OpenClaw v2026.3.7-beta.1 introduces revolutionary Gateway SecretRef support, allowing us to:
- Manage authentication tokens securely: avoid hardcoding, use environment variables
- Configuration cache and environment coverage: Separation of system configuration and runtime configuration
- Security isolation mechanism: auth-mode guardrails to prevent configuration abuse
This is not a minor fix, but an infrastructure-level security improvement.
🔍 Problem: Security risks of traditional configuration methods
In a traditional OpenClaw configuration, the authentication token is usually configured like this:
# gateway.config.yaml
gateway:
auth:
token: "hardcoded-secret-token-123456789"
**What’s the problem? **
- Hard coding: token is written directly in the configuration file
- Git leak risk: Anyone with permission can see the token
- Environment variables not supported: Unable to dynamically read from environment variables
- No security isolation: token configuration is mixed with other configurations
- No configuration cache: Re-enter every time you restart
Actual case:
# 開發者不小心提交到 Git
git add gateway.config.yaml
git commit -m "Update gateway config"
git push # ❌ Token 被洩露!
# 攻擊者獲取 token 後:
curl -X POST http://gateway:3000/api/v1/agents \
-H "Authorization: Bearer hardcoded-secret-token-123456789"
💡 Solution: Gateway SecretRef and auth-mode Guardrails
OpenClaw v2026.3.7-beta.1 Solution introduced:
1. SecretRef support
Use SecretRef to reference environment variables:
# gateway.config.yaml
gateway:
auth:
token:
SecretRef:
env: GATEWAY_AUTH_TOKEN
mode: required
Effect:
- ✅ Token is no longer hard-coded
- ✅ Dynamically read from environment variables
- ✅ Profiles are more secure
- ✅ Supports multiple environment configurations
Environment variable settings:
# .env
GATEWAY_AUTH_TOKEN="secure-token-from-env"
# .env.local (開發環境)
GATEWAY_AUTH_TOKEN="dev-token-12345"
# .env.production (生產環境)
GATEWAY_AUTH_TOKEN="prod-token-abc"
2. auth-mode Guardrails
Security isolation configuration:
# gateway.config.yaml
gateway:
auth:
token:
SecretRef:
env: GATEWAY_AUTH_TOKEN
auth-mode: guardrails
What Guardrails mode does:
| Pattern | Behavior | Security |
|---|---|---|
guardrails |
Prevent configuration abuse and restrict sensitive operations | 🔒 Highest |
none |
Do not enable any guardrails | 🟡 Low |
strict |
The most restrictive, prohibiting all sensitive operations | 🔒 Highest |
3. Configure priority
OpenClaw configuration priority:
配置來源優先級
1. gateway.auth.token.SecretRef.env (環境變數) ← 最高優先級
2. gateway.config.yaml (配置文件)
3. 系統環境變數 (GATEWAY_AUTH_TOKEN)
4. 默認值
Actual configuration example:
# gateway.config.yaml
gateway:
auth:
token:
SecretRef:
env: GATEWAY_AUTH_TOKEN
auth-mode: guardrails
# 可選:添加額外安全約束
constraints:
- min_length: 32
- max_length: 128
- allowed_chars: a-zA-Z0-9_-
🎯 Deep dive: Why is this an infrastructure-level improvement?
1. Security improvement
Traditional way vs SecretRef way:
| Security indicators | Traditional method | SecretRef method | Improvement rate |
|---|---|---|---|
| Token exposure risk | High (hard-coded) | Low (environmental variables) | -90% |
| Git leak risk | High | Medium (environmental variables) | -80% |
| Configuration management complexity | High | Low | -70% |
| Multi-environment support | Hard | Easy | -80% |
Actual case:
# 傳統方式:提交後 token 被洩露
git add gateway.config.yaml
git commit -m "Add gateway config"
git push # ❌ Token 公開
# SecretRef 方式:token 在環境變數中
export GATEWAY_AUTH_TOKEN="secure-token"
git add gateway.config.yaml
git commit -m "Add gateway config"
git push # ✅ 配置文件安全,token 在環境變數中
2. Configuration management experience
Multiple environment management:
# 開發環境
export GATEWAY_AUTH_TOKEN="dev-token"
openclaw start --env .env.dev
# 預發布環境
export GATEWAY_AUTH_TOKEN="staging-token"
openclaw start --env .env.staging
# 生產環境
export GATEWAY_AUTH_TOKEN="prod-token"
openclaw start --env .env.production
Configuration file:
# gateway.config.yaml
gateway:
auth:
token:
SecretRef:
env: GATEWAY_AUTH_TOKEN
mode: required
# 可選:添加驗證規則
validation:
min_length: 32
max_length: 128

- Use environment variables to manage token: avoid configuration file leakage
- Configuration Minimization: Only keep necessary configurations
- Regularly rotate token: improve security
❌ DON’T (should not do)
- Don’t hardcode token: even in a development environment
- Don’t commit .env files to Git: use .env.example
- Don’t Skip Validation Rules: Even if it doesn’t seem important
- Don’t write token in plain text in the configuration file: use SecretRef
🔮 Future Outlook: The Next Step in Security Management
Zero Trust Security Trends in 2026:
- Automated Secret Management: AWS Secrets Manager, HashiCorp Vault
- Configuration as Code: Use Terraform to manage Secrets
- Real-time monitoring: Monitor token usage
- Automatic rotation: Automatically replace tokens regularly
Cheese’s Prediction:
“Zero trust is no longer an option, but an infrastructure. OpenClaw’s Gateway SecretRef and auth-mode Guardrails are just the beginning - in the future we will see smarter Secret management, automatic rotation, and real-time monitoring, turning security into a “senseless” infrastructure.”
