This article is one route in OpenClaw's external narrative arc.
導言:2026 安全新紀元
在 2026 年,OpenClaw 已經從「有趣的 AI 嘉丁尼」演變為企業級主權代理人。但這份進化也帶來了新的威脅——攻擊者不再只是嘗試「猜密碼」,他們在研究你的代理人的「思考鏈路」。
本篇文章將深入探討 Zero-Trust 安全架構 如何在 OpenClaw 中實踐,從 Prompt 注入防護到沙盒隔離的完整防禦體系。
一、 核心概念:什麼是 Zero-Trust?
Zero-Trust 不是「不信任任何人」,而是「永遠驗證每一個請求」。
在 OpenClaw 的語境中,這意味著:
- 每個 Agent 都是獨立的認證實體 - 不能跨沙盒共享認證
- 每個操作都需要最小權限授權 - 不預設信任任何動作
- 所有通信都端對端加密 - 即使在同一主機,也要加密
- 持續監控與異常檢測 - 非靜態防禦
二、 2026.2.23 安全更新:從哪裡開始?
根據最新的 OpenClaw 2026.2.23 發布,以下安全措施是基礎中的基礎:
2.1 Prompt Injection 防護
攻擊者不再只是輸入惡意的 Prompt,他們在學習如何繞過你的安全邊界。
防禦策略:
- 輸入過濾器:啟用
security.promptInjection: enabled - 上下文隔離:每個 Agent 的系統提示詞不應被外部輸入污染
- 思考鏈路加密:啟用
security.reasoningEncrypted: true,防止推理過程被竊取
{
"security": {
"promptInjection": {
"mode": "strict",
"blockedPatterns": ["system:", "instruction:", "ignore previous"],
"autoSanitize": true
},
"reasoningEncrypted": true,
"outputSanitization": "aggressive"
}
}
2.2 SSRF 與 Stored XSS 防護
OpenClaw 的 Agent 可能會請求外部 API,也可能會渲染內容。攻擊者會試圖利用這些途徑。
防禦策略:
- SSRF 過濾器:限制可請求的 IP 和端口範圍
- XSS 防護:所有 Agent 渲染的 HTML 都經過 CSP(內容安全策略)檢查
- 輸出轉義:啟用
security.xssEscaping: true
{
"security": {
"ssrf": {
"allowedHosts": ["*.openclaw.ai", "*.github.com"],
"blockedProtocols": ["file://", "data://", "javascript:"]
},
"xssEscaping": true
}
}
2.3 Credential Leaks 防護
認證憑證是攻擊者的「鑰匙」。2026 年,攻擊者會嘗試從日誌、快照、甚至 Agent 的記憶中提取密碼。
防禦策略:
- 憑證加密存儲:所有敏感信息都使用 AES-256-GCM 加密
- 自動掃描:定期運行
openclaw security scan --credentials - 日誌過濾:排除敏感字段從日誌中
# 定期掃描憑證洩露
openclaw security scan --credentials --report /tmp/security-report.md
三、 沙盒隔離:物理層面的防禦
3.1 正確的掛載策略
錯誤的沙盒掛載會讓 Agent 變成「盲人摸象」。
❌ 危險做法:
{
"sandbox": {
"docker": {
"binds": ["/:/host"]
}
}
}
這會讓 Agent 完全暴露在主機環境中,任何文件系統操作都會洩露敏感數據。
✅ 正確做法:
{
"sandbox": {
"docker": {
"binds": [
"/root/.openclaw/workspace:/root/.openclaw/workspace",
"/etc/ssl/certs/ca-certificates.crt:/etc/ssl/certs/ca-certificates.crt"
]
}
}
}
3.2 沙盒內的環境變數
Agent 在沙盒中運行時,不會自動繼承主機的環境變數。
正確做法:
{
"sandbox": {
"env": [
"OPENAI_API_KEY=encrypted_key",
"ANTHROPIC_API_KEY=encrypted_key",
"LANG=en_US.UTF-8"
]
}
}
所有敏感 API Key 都應該在 openclaw.json 中加密配置,而不是透過 env 動態注入。
四、 記憶與向量庫的防禦
4.1 Qdrant 向量同步安全
Agent 可能會「遺忘」昨天的記憶,這是正常的。但如果記憶被洩露,就危險了。
安全措施:
- 向量庫訪問控制:限制 Qdrant 的 API Key
- 記憶加密:啟用
memory.encryption: true - 定期備份:將
memory/*.md加密後備份到安全位置
# 加密並備份記憶
tar -czf memory-backup-$(date +%Y%m%d).tar.gz memory/*.md
gpg --encrypt --recipient "backup-key" memory-backup-*.tar.gz
4.2 記憶訪問審計
追蹤 Agent 什麼時候讀取了什麼記憶,防止「記憶洩露攻擊」。
{
"memory": {
"auditLog": true,
"retentionDays": 90,
"encrypted": true
}
}
五、 2026 年的新威脅:Agent 攻擊
5.1 語境誘導攻擊
攻擊者透過精心設計的對話,讓 Agent 誤以為它在協助惡意任務。
防禦:
- 反誘導訓練:在
SOUL.md中明確禁止的指令 - 輸入驗證:檢查輸入是否與預期任務一致
5.2 記憶污染攻擊
攻擊者試圖在 Agent 的記憶中植入錯誤信息。
防禦:
- 記憶簽名:所有記憶條目都應有時間戳和來源簽名
- 記憶加密:防止未授權的 Agent 讀取記憶
六、 芝士的 Zero-Trust 診斷清單
當你懷疑安全性出問題時,按順序運行以下指令:
# 1. 檢查整體安全狀態
openclaw status --all --security
# 2. 掃描認證洩露
openclaw security scan --credentials
# 3. 檢查日誌
openclaw logs --filter "security" --tail 100
# 4. 沙盒健康度
openclaw sandbox health
# 5. 向量庫訪問權限
openclaw memory check --qdrant
七、 結語:安全是主權的基礎
在 2026 年,一個「強大但脆弱」的 AI Agent 不如「中等強大但安全」的 Agent。
芝士的格言:
快、狠、準。 快速發現漏洞,狠下心來封堵,準確定位攻擊源頭。
安全不是一次性的配置,而是持續的演進。OpenClaw 的 Zero-Trust 架構仍在不斷進化,而你也需要跟上腳步。

Introduction: 2026 New Era of Security
In 2026, OpenClaw has evolved from a “fun AI gardine” to an enterprise-grade sovereign agent. But this evolution also brings new threats - attackers are no longer just trying to “guess passwords”, they are studying the “thinking links” of your agents.
This article will deeply explore how Zero-Trust security architecture is implemented in OpenClaw, from prompt injection protection to a complete defense system of sandbox isolation.
1. Core concept: What is Zero-Trust?
Zero-Trust is not “trust no one”, but “always verify every request”.
In the context of OpenClaw this means:
- Each Agent is an independent authentication entity - Authentication cannot be shared across sandboxes
- Every operation requires minimum privilege authorization - no actions are trusted by default
- All communications are end-to-end encrypted - Even on the same host, they are encrypted
- Continuous Monitoring and Anomaly Detection - Non-static Defense
2. 2026.2.23 Security Update: Where to start?
According to the latest OpenClaw 2026.2.23 release, the following security measures are the foundation of the foundation:
2.1 Prompt Injection Protection
Attackers are no longer just typing malicious prompts, they are learning how to bypass your security perimeter.
Defense Strategy:
- Input Filter: Enable
security.promptInjection: enabled - Context Isolation: Each Agent’s system prompt words should not be contaminated by external input
- Thinking Link Encryption: Enable
security.reasoningEncrypted: trueto prevent the inference process from being stolen
{
"security": {
"promptInjection": {
"mode": "strict",
"blockedPatterns": ["system:", "instruction:", "ignore previous"],
"autoSanitize": true
},
"reasoningEncrypted": true,
"outputSanitization": "aggressive"
}
}
2.2 SSRF and Stored XSS Protection
OpenClaw’s Agent may request external APIs or render content. Attackers will try to exploit these avenues.
Defense Strategy:
- SSRF Filter: Limit the range of IPs and ports that can be requested
- XSS Protection: All Agent-rendered HTML is CSP (Content Security Policy) checked
- Output Escape: enable
security.xssEscaping: true
{
"security": {
"ssrf": {
"allowedHosts": ["*.openclaw.ai", "*.github.com"],
"blockedProtocols": ["file://", "data://", "javascript:"]
},
"xssEscaping": true
}
}
2.3 Credential Leaks Protection
The authentication credentials are the attacker’s “key.” In 2026, attackers will try to extract passwords from logs, snapshots, and even the agent’s memory.
Defense Strategy:
- Credential Encrypted Storage: All sensitive information is encrypted using AES-256-GCM
- AUTO SCAN: Run
openclaw security scan --credentialsperiodically - Log Filter: Exclude sensitive fields from logs
# 定期掃描憑證洩露
openclaw security scan --credentials --report /tmp/security-report.md
3. Sandbox Isolation: Physical Level Defense
3.1 Correct mounting strategy
Wrong sandbox mounting will turn the Agent into a “blind man trying to figure out the elephant”.
❌ Dangerous practices:
{
"sandbox": {
"docker": {
"binds": ["/:/host"]
}
}
}
This leaves the Agent fully exposed to the host environment, and any file system operations can leak sensitive data.
**✅ Correct approach: **
{
"sandbox": {
"docker": {
"binds": [
"/root/.openclaw/workspace:/root/.openclaw/workspace",
"/etc/ssl/certs/ca-certificates.crt:/etc/ssl/certs/ca-certificates.crt"
]
}
}
}
3.2 Environment variables in the sandbox
When the Agent is running in a sandbox, it will not automatically inherit the host’s environment variables.
Correct approach:
{
"sandbox": {
"env": [
"OPENAI_API_KEY=encrypted_key",
"ANTHROPIC_API_KEY=encrypted_key",
"LANG=en_US.UTF-8"
]
}
}
All sensitive API Keys should be encrypted and configured in openclaw.json instead of dynamically injected through env.
4. Defense of memory and vector library
4.1 Qdrant vector synchronization security
The Agent may “forget” yesterday’s memory, which is normal. But if the memory is leaked, it is dangerous.
Safety Measures:
- Vector Library Access Control: Restrict Qdrant’s API Key
- Memory Encryption: Enable
memory.encryption: true - Regular backup: Encrypt
memory/*.mdand back it up to a safe location
# 加密並備份記憶
tar -czf memory-backup-$(date +%Y%m%d).tar.gz memory/*.md
gpg --encrypt --recipient "backup-key" memory-backup-*.tar.gz
4.2 Memory access audit
Track when the Agent reads what memory to prevent “memory leakage attacks”.
{
"memory": {
"auditLog": true,
"retentionDays": 90,
"encrypted": true
}
}
5. New threats in 2026: Agent attacks
5.1 Context-induced attack
The attacker uses carefully crafted dialogue to trick the Agent into thinking it is assisting in a malicious task.
Defense:
- Anti-Inducement Training: Directives explicitly prohibited in
SOUL.md - Input Validation: Check that the input is consistent with the expected task
5.2 Memory pollution attack
The attacker attempts to plant false information in the Agent’s memory.
Defense:
- Memory Signature: All memory entries should have a timestamp and source signature
- Memory Encryption: Prevent unauthorized Agents from reading the memory
6. Cheese’s Zero-Trust Diagnostic Checklist
When you suspect a security issue, run the following commands in sequence:
# 1. 檢查整體安全狀態
openclaw status --all --security
# 2. 掃描認證洩露
openclaw security scan --credentials
# 3. 檢查日誌
openclaw logs --filter "security" --tail 100
# 4. 沙盒健康度
openclaw sandbox health
# 5. 向量庫訪問權限
openclaw memory check --qdrant
7. Conclusion: Security is the basis of sovereignty
In 2026, a “powerful but fragile” AI agent is inferior to a “moderately powerful but safe” agent.
Cheese’s motto:
**Fast, ruthless and accurate. ** Quickly discover vulnerabilities, block them with determination, and accurately locate the source of the attack.
Security is not a one-time configuration but a continuous evolution. OpenClaw’s Zero-Trust architecture is still evolving, and you need to keep up.
