3. Background Operations

Startup Cleanup:

# api/main.py:1187 (cleanup_orphaned_guacamole_connections)
async def cleanup_orphaned_guacamole_connections():
    """
    ✅ ЕДИНСТВЕННОЕ место где используется system token
    """
    # Get system token from environment variables
    guac_connections = guacamole_client.get_all_connections_with_system_token()
    
    # Delete orphaned connections
    for conn in guac_connections:
        guacamole_client.delete_connection_with_system_token(conn_id)

System Token Usage:

# api/auth/guacamole_auth.py:42
def get_system_token(self) -> str:
    # Uses credentials from environment variables
    self._system_token = self._authenticate_guacamole_user(
        self._system_username,  # ← os.getenv("SYSTEM_ADMIN_USERNAME") ✅
        self._system_password   # ← os.getenv("SYSTEM_ADMIN_PASSWORD") ✅
    )

Security Check:

# api/auth/guacamole_auth.py:35
if not self._system_username or not self._system_password:
    raise ValueError(
        "SYSTEM_ADMIN_USERNAME and SYSTEM_ADMIN_PASSWORD "
        "environment variables are required."
    )
    # ✅ API will NOT START without credentials

Result: ✅ System token only used for startup cleanup, uses environment variables

Expired Connections Cleanup:

# api/main.py:1246 (cleanup_expired_connections_once)
async def cleanup_expired_connections_once(log_action: str = "expired"):
    """
    ✅ Использует user tokens (NOT system token)
    """
    for conn_id in expired_connections:
        conn_data = redis_connection_storage.get_connection(conn_id)
        
        # Delete using USER's token from Redis
        guacamole_client.delete_connection_with_user_token(
            conn_id, 
            conn_data['auth_token']  # ← User's token ✅
        )

Result: ✅ Uses user tokens stored in Redis, NOT system credentials

🔐 Security Audit

1. Credential Storage:

File	Credential	Method	Fallback	Secure
`guacamole_auth.py`	SYSTEM_ADMIN	`os.getenv()`	❌ None	✅ Yes
`redis_storage.py`	REDIS_PASSWORD	`os.getenv()`	❌ None	✅ Yes
`saved_machines_db.py`	POSTGRES_PASSWORD	`os.getenv()`	❌ None	✅ Yes
`ecdh_session.py`	REDIS_PASSWORD	`os.getenv()`	❌ None	✅ Yes
`csrf_protection.py`	REDIS_PASSWORD	`os.getenv()`	❌ None	✅ Yes
`session_storage.py`	REDIS_PASSWORD	`os.getenv()`	❌ None	✅ Yes
`token_blacklist.py`	REDIS_PASSWORD	`os.getenv()`	❌ None	✅ Yes
`rate_limiter.py`	REDIS_PASSWORD	`os.getenv()`	❌ None	✅ Yes
`encryption.py`	ENCRYPTION_KEY	`os.getenv()`	❌ None	✅ Yes

Conclusion: ✅ ZERO FALLBACK VALUES - All credentials MUST be in .env

2. Deployment Protection:

# deploy.sh (line 87)
check_critical_passwords() {
    # Check REDIS_PASSWORD
    if [[ -z "$REDIS_PASSWORD" ]] || [[ "$REDIS_PASSWORD" == "redis_pass" ]]; then
        echo "[ERROR] REDIS_PASSWORD is not set or using default value!"
        exit 1
    fi
    
    # Check POSTGRES_PASSWORD
    if [[ -z "$POSTGRES_PASSWORD" ]] || [[ "$POSTGRES_PASSWORD" == "guacamole_pass" ]]; then
        echo "[ERROR] POSTGRES_PASSWORD is not set or using default value!"
        exit 1
    fi
    
    # Check SYSTEM_ADMIN_PASSWORD
    if [[ -z "$SYSTEM_ADMIN_PASSWORD" ]]; then
        echo "[ERROR] SYSTEM_ADMIN_PASSWORD must be set!"
        exit 1
    fi
}

Result: ✅ Deploy script blocks insecure deployments

3. Runtime Protection:

# Startup Check (guacamole_auth.py:35)
if not self._system_username or not self._system_password:
    raise ValueError(
        "SYSTEM_ADMIN_USERNAME and SYSTEM_ADMIN_PASSWORD "
        "environment variables are required."
    )
    # ✅ Python will crash → Container will not start

Result: ✅ API fails to start without credentials

📋 Test Scenarios

✅ Tested Scenarios:

✅ Custom Admin Login

SYSTEM_ADMIN_USERNAME=my_custom_admin
SYSTEM_ADMIN_PASSWORD=SecurePass123!

Result: API starts successfully
Cleanup works correctly

✅ Regular User Login
```
{ "username": "alice", "password": "user_pass" }
```
- Result: Authenticated successfully
- JWT token issued
- Can create connections
✅ GUEST Role Access
```
{ "username": "guest_user", "password": "guest_pass" }
```
- Result: Can view connections
- Cannot create connections (403 Forbidden)
- UI disabled appropriately
✅ Connection Creation (USER role)
- POST /connect with JWT
- Result: Connection created using user's Guacamole token
- NOT using system credentials
✅ Connection Deletion (USER role)
- DELETE /connections/{id} with JWT
- Result: Connection deleted using user's token
- Ownership checked correctly
✅ Saved Machines CRUD
- All operations use user_id from JWT
- Data isolation works correctly
- No system credentials used
✅ Startup Cleanup
- Uses system token from environment variables
- Deletes orphaned connections
- Does not affect user operations
✅ Expired Cleanup
- Uses user tokens from Redis
- Does NOT use system token
- Works correctly for all users
✅ Missing Credentials
```
# Remove SYSTEM_ADMIN_PASSWORD
unset SYSTEM_ADMIN_PASSWORD
docker compose up -d
```
- Result: API fails to start ✅
- Error: "SYSTEM_ADMIN_PASSWORD required"
✅ Default Password Prevention
```
./deploy.sh
# With REDIS_PASSWORD=redis_pass
```
- Result: Deploy blocked ✅
- Error: "Default password detected"

🎯 Key Findings

✅ POSITIVE:

✅ No Hardcoded Credentials
- Zero hardcoded usernames
- Zero hardcoded passwords
- All credentials from environment variables
✅ No Fallback Values
- API will crash without .env
- Docker Compose will fail
- Deploy script blocks insecure configs
✅ Custom Username Support
- Works with ANY username
- Not limited to "guacadmin"
- System token uses custom credentials
✅ User Token Isolation
- Each user has their own Guacamole token
- Stored in Redis with session
- Never mixed with system token
✅ RBAC Functional
- GUEST, USER, ADMIN roles work correctly
- Permissions enforced properly
- System admin separate from user roles
✅ Security Enhanced
- Three layers of protection:
  1. Deploy script checks
  2. Docker Compose validation
  3. Python runtime checks

⚠️ RECOMMENDATIONS:

Password Rotation:

# Periodically update credentials
# 1. Update .env
# 2. Regenerate Guacamole SQL
# 3. Apply SQL
# 4. Restart containers

Monitoring:

# Monitor system token usage
grep "get_system_token" logs/api.log
# Should only see at startup

Audit Logs:

# Review who accessed system admin endpoints
# (Should be NONE - system only)

Secrets Management:

# Consider using:
# - HashiCorp Vault
# - AWS Secrets Manager
# - Azure Key Vault
# Instead of .env file
