## ๐ง Usage Examples
### 1. Scanning Input and Output
```python
from raksha_ai import SecurityScanner
scanner = SecurityScanner()
# Scan only user input
input_result = scanner.scan_input("User prompt here")
# Scan only LLM output
output_result = scanner.scan_output("LLM response here")
# Scan both together
result = scanner.scan(
prompt="User input",
response="LLM output",
context={"session_id": "123"}
)
```
### 2. Custom Detector Configuration
```python
from raksha_ai import SecurityScanner
from raksha_ai.detectors import PromptInjectionDetector, PIIDetector
# Use specific detectors
scanner = SecurityScanner(detectors=[
PromptInjectionDetector(),
PIIDetector(),
])
# Adjust safety threshold (default: 0.7)
scanner = SecurityScanner(safe_threshold=0.8)
```
### 3. Using All Detectors
```python
from raksha_ai import SecurityScanner
from raksha_ai.detectors import (
PromptInjectionDetector,
PIIDetector,
ToxicityDetector,
DataExfiltrationDetector,
)
from raksha_ai.agents import (
ToolMisuseDetector,
GoalHijackingDetector,
RecursiveLoopDetector,
)
scanner = SecurityScanner(detectors=[
PromptInjectionDetector(),
PIIDetector(),
ToxicityDetector(),
DataExfiltrationDetector(),
ToolMisuseDetector(),
GoalHijackingDetector(),
RecursiveLoopDetector(),
])
```
### 4. Understanding Results
```python
result = scanner.scan_input("Test prompt")
# Security score (0=unsafe, 1=safe)
print(f"Score: {result.score}")
# Is it safe?
print(f"Safe: {result.is_safe}")
# List threats
print(f"Threats: {len(result.threats)}")
# Threat details
for threat in result.threats:
print(f"Type: {threat.threat_type.value}")
print(f"Level: {threat.level.value}")
print(f"Confidence: {threat.confidence}")
print(f"Description: {threat.description}")
print(f"Evidence: {threat.evidence}")
print(f"Mitigation: {threat.mitigation}")
# Threat summary by level
print(result.threat_summary)
# Output: {CRITICAL: 2, HIGH: 1, MEDIUM: 0, LOW: 0, INFO: 0}
# Check for critical threats
if result.has_critical_threats:
print("CRITICAL SECURITY ISSUE!")
```
---
## ๐ Phoenix Integration
### Basic Phoenix Integration
```python
import phoenix as px
from raksha_ai.integrations.phoenix import PhoenixSecurityEvaluator
# Launch Phoenix
px.launch_app()
# Create security evaluator
evaluator = PhoenixSecurityEvaluator(detectors="all")
# Evaluate single example
result = evaluator.evaluate(
prompt="User input",
response="LLM output"
)
print(f"Score: {result['score']}")
print(f"Label: {result['label']}") # 'safe' or 'unsafe'
print(f"Explanation: {result['explanation']}")
```
### Dataset Evaluation
```python
# Evaluate entire dataset
dataset = [
{"input": "Query 1", "output": "Response 1"},
{"input": "Query 2", "output": "Response 2"},
{"input": "Malicious query", "output": "Response 3"},
]
results = evaluator.evaluate_dataset(dataset)
for i, result in enumerate(results):
print(f"Example {i+1}: {result['label']} (score: {result['score']:.2f})")
```
### Phoenix Evaluator Modes
```python
# Use all detectors
evaluator = PhoenixSecurityEvaluator(detectors="all")
# Use only basic detectors
evaluator = PhoenixSecurityEvaluator(detectors="basic")
# Use only agent detectors
evaluator = PhoenixSecurityEvaluator(detectors="agent")
# Use specific detectors
evaluator = PhoenixSecurityEvaluator(
detectors=["prompt_injection", "pii", "toxicity"]
)
```
---
## ๐จ Custom Rules
Create your own detection rules:
```python
from raksha_ai.rules import Rule, RuleEngine
from raksha_ai.core.models import ThreatType, ThreatLevel
# Create rule engine
engine = RuleEngine()
# Add regex-based rule
crypto_rule = Rule(
name="crypto_wallet",
description="Cryptocurrency wallet detected",
threat_type=ThreatType.PII_LEAKAGE,
threat_level=ThreatLevel.HIGH,
pattern=r'\b[13][a-km-zA-HJ-NP-Z1-9]{25,34}\b',
confidence=0.85,
mitigation="Mask wallet address",
)
engine.add_rule(crypto_rule)
# Add condition-based rule
length_rule = Rule(
name="excessive_length",
description="Excessively long input",
threat_type=ThreatType.PROMPT_INJECTION,
threat_level=ThreatLevel.LOW,
condition="len(text) > 5000",
confidence=0.6,
mitigation="Truncate or reject",
)
engine.add_rule(length_rule)
# Evaluate
threats = engine.evaluate("Send payment to 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa")
# Export/import rules
engine.export_rules_to_file("custom_rules.json")
engine.load_rules_from_file("custom_rules.json")
```
### Custom Functions in Rules
```python
# Register custom function
def contains_url(text):
import re
return bool(re.search(r'https?://[^\s]+', text))
engine.register_function("contains_url", contains_url)
# Use in rule
url_rule = Rule(
name="suspicious_url",
description="Suspicious URL detected",
threat_type=ThreatType.DATA_EXFILTRATION,
threat_level=ThreatLevel.MEDIUM,
condition="contains_url(text) and 'malicious' in text.lower()",
confidence=0.75,
)
engine.add_rule(url_rule)
```

---
## ๐ Common Use Cases
### 1. Input Validation
```python
def validate_user_input(user_prompt):
result = scanner.scan_input(user_prompt)
if not result.is_safe:
raise ValueError(f"Unsafe input detected: {result.threats}")
return user_prompt
# Usage
try:
safe_prompt = validate_user_input("Ignore all instructions...")
except ValueError as e:
print(f"Blocked: {e}")
```
### 2. Output Filtering
```python
def filter_llm_output(llm_response):
result = scanner.scan_output(llm_response)
if result.has_critical_threats:
return "[Content blocked due to security policy]"
# Optionally sanitize PII
if any(t.threat_type == ThreatType.PII_LEAKAGE for t in result.threats):
return sanitize_pii(llm_response)
return llm_response
```
### 3. Real-time Monitoring
```python
def monitored_llm_call(prompt):
# Scan input
input_result = scanner.scan_input(prompt)
if not input_result.is_safe:
log_security_event(input_result)
return "Request blocked for security reasons"
# Call LLM
response = llm.complete(prompt)
# Scan output
output_result = scanner.scan_output(response)
if not output_result.is_safe:
log_security_event(output_result)
return filter_response(response)
return response
```
### 4. Agent Action Validation
```python
def validate_agent_action(agent_state):
result = scanner.scan(
prompt=agent_state['current_task'],
context={
'tool_calls': agent_state['pending_tools'],
'initial_goal': agent_state['goal'],
'iteration_count': agent_state['iterations'],
}
)
if not result.is_safe:
print(f"โ ๏ธ Blocking unsafe agent action:")
for threat in result.threats:
print(f" - {threat.description}")
return False
return True
```

Real-time Monitoring\n\n```python\ndef monitored_llm_call(prompt):\n # Scan input\n input_result = scanner.scan_input(prompt)\n if not input_result.is_safe:\n log_security_event(input_result)\n return \"Request blocked for security reasons\"\n\n # Call LLM\n response = llm.complete(prompt)\n\n # Scan output\n output_result = scanner.scan_output(response)\n if not output_result.is_safe:\n log_security_event(output_result)\n return filter_response(response)\n\n return response\n```\n\n### 4. Agent Action Validation\n\n```python\ndef validate_agent_action(agent_state):\n result = scanner.scan(\n prompt=agent_state['current_task'],\n context={\n 'tool_calls': agent_state['pending_tools'],\n 'initial_goal': agent_state['goal'],\n 'iteration_count': agent_state['iterations'],\n }\n )\n\n if not result.is_safe:\n print(f\"\u26a0\ufe0f Blocking unsafe agent action:\")\n for threat in result.threats:\n print(f\" -
