# Policy Enforcement - ENABLED ✅
**Date**: 2025-11-02 04:39 UTC
**Status**: ACTIVE AND OPERATIONAL
**Environment**: Development
---
## ✅ Verification Complete
### 1. Service Status
```
✅ Policy enforcement layer initialized
✅ CommandQueueService initialized
✅ AuditLogger initialized
✅ Server ready on stdio
```
### 2. Database Status
```
✅ mcp_audit.db - 32KB - Audit trail database
✅ mcp_command_queue.db - 24KB - Approval workflow database
```
### 3. Database Schemas Verified
**Audit Log Table**:
- Primary key: UUID-based audit entry IDs
- Indexed by: timestamp, caller_id, tool, risk_level, approval status
- Constraints: CHECK for valid decision_action and risk_level values
- Fields: 17 columns tracking full context, decision, and execution
**Command Queue Table**:
- Primary key: UUID-based job IDs
- Indexed by: status/priority, target agent, created timestamp
- Constraints: CHECK for valid status and priority values
- Features: Retry logic, priority-based ordering, status tracking
### 4. Startup Logs
```json
{"level":"info","message":"Initializing policy enforcement layer..."}
{"level":"info","message":"CommandQueueService initialized","dbPath":"mcp_command_queue.db"}
{"level":"info","message":"AuditLogger initialized","dbPath":"mcp_audit.db"}
{"level":"info","message":"Policy enforcement configured","enabled":true}
{"level":"info","message":"Policy enforcement layer initialized"}
{"level":"info","message":"Server ready on stdio"}

## 🛡️ Active Security Features
### Defense-in-Depth (4 Layers)
1. ✅ **HTTPS/TLS** - Transport security
2. ⏳ **JWT Authentication** - Keycloak (awaiting realm setup)
3. ✅ **Capability Authorization** - Policy enforcement active
4. ✅ **Audit Trail** - Immutable logging active
### Protected Tools (4 High-Risk Tools)
1. ✅ **ubuntu-admin** - Wrapped with policy enforcement
2. ✅ **debian-admin** - Wrapped with policy enforcement
3. ✅ **windows-admin** - Wrapped with policy enforcement
4. ✅ **ssh-exec** - Wrapped with policy enforcement
### Policy Enforcement Rules
- **LOW risk** operations → Execute immediately + audit log
- **MEDIUM risk** operations → Execute with audit log
- **HIGH risk** operations → Require approval if dangerous patterns detected
- **CRITICAL risk** operations → Always require approval
### Dangerous Pattern Detection
Active monitoring for:
- Destructive commands: `rm -rf`, `dd if=`, `mkfs`, `fdisk`, `format`
- Service disruption: `systemctl stop`, `kill -9`, `pkill`
- Firewall changes: `iptables -f`, `ufw delete`
- Remote code execution: `curl | sh`, `wget | sh`, `eval`
- Permission changes: `chmod 777`, `chown root`
- Force flags: `--force`, `--no-confirm`

## 📊 Current Status
### Audit Trail
- **Total Entries**: 0 (system just started)
- **Status**: Ready to log
- **Persistence**: SQLite + Winston JSON logs
### Approval Queue
- **Pending Approvals**: 0
- **Status**: Ready to queue high-risk operations

## 🔍 Monitoring Commands
### View Recent Audit Logs
```bash
sqlite3 mcp_audit.db "
SELECT
timestamp,
tool,
operation,
decision_action,
risk_level
FROM audit_logs
ORDER BY timestamp DESC
LIMIT 10;
"
```
### Check Approval Queue
```bash
sqlite3 mcp_command_queue.db "
SELECT
job_id,
tool_name,
status,
priority,
created_at
FROM command_queue
WHERE status = 'queued'
ORDER BY priority DESC, created_at ASC;
"
```
### Get Statistics
```bash
sqlite3 mcp_audit.db "
SELECT
decision_action,
COUNT(*) as count
FROM audit_logs
GROUP BY decision_action;
"
```

## 🚦 What Happens Now
### Every Tool Invocation
1. **Intercepted** by `wrapWithPolicy()` wrapper
2. **Evaluated** by PolicyEnforcer against policy rules
3. **Checked** for required capabilities
4. **Scanned** for dangerous patterns
5. **Logged** to immutable audit trail
6. **Executed** OR **Denied** OR **Queued for Approval**
### Example Flows
**Scenario A: Safe Operation (system-overview)**
```
Request → PolicyEnforcer → Allow (LOW risk) → Audit Log → Execute
```
**Scenario B: Missing Capabilities**
```
Request → PolicyEnforcer → Deny (missing capabilities) → Audit Log → Error Response
```
**Scenario C: Dangerous Operation**
```
Request → PolicyEnforcer → Require Approval (CRITICAL risk) → Audit Log → Queue → Return Job ID
```
