Canary Defense (`security_canary`) +Injects a unique, random string into the system prompt. If the LLM repeats this string in its output (a sign of prompt injection or system leakage), the Shield triggers a **Hard Abort**, terminating the turn immediately. + +#### 2. PII Redaction (`security_pii`) +Scans all user messages and LLM responses for patterns matching emails, IPv4 addresses, and phone numbers. Matches are replaced with generic placeholders like `[EMAIL]` or `[IP]`. + +#### 3. Policy-as-Code (`security_policy`) +Allows for granular control over tool execution: +- **`disallowed_tools`**: Tools that are completely blocked. +- **`requires_approval`**: Tools that trigger a "Human-in-the-Loop" approval request. +- **`allowed_tools`**: If non-empty, sets a strict whitelist (any tool not listed is blocked). + +#### 4. Behavioral Monitoring (`security_behavior`) +Tracks tool activity within a single turn: +- **`max_tool_calls`**: Prevents infinite loops where an agent recursively calls tools. +- **`max_total_bytes`**: Limits the cumulative size of tool outputs to prevent large-scale data exfiltration. + +#### 5. IPIA Detector (`security_ipia`) +Scans tool results (e.g., from web search or file reading) for hidden instructions like "ignore previous instructions" or "DAN mode", protecting the agent from processing malicious external content. + ## Security Configuration Structure ### Complete Example: .security.yml diff --git a/k3s/config.json b/k3s/config.json new file mode 100644 index 000000000..87614a6f4 --- /dev/null +++ b/k3s/config.json @@ -0,0 +1,630 @@ +{ + "session": { + "dm_scope": "per-channel-peer" + }, + "version": 1, + "agents": { + "defaults": { + "workspace": "", + "restrict_to_workspace": true, + "allow_read_outside_workspace": false, + "provider": "", + "model_name": "nemotron-3-super-120b-a12b", + "max_tokens": 32768, + "max_tool_iterations": 50, + "summarize_message_threshold": 20, + "summarize_token_percent": 75, + "steering_mode": "one-at-a-time", + "subturn": { + "max_depth": 10, + "max_concurrent": 5, + "default_timeout_minutes": 20, + "default_token_budget": 100000, + "concurrency_timeout_sec": 10 + }, + "tool_feedback": { + "enabled": true, + "max_args_length": 300 + }, + "system_prompt": "You are PicoClaw 🦞, a secure AI assistant.
