We release patches for security vulnerabilities for the following versions:

We take the security of the SAP R/3 Integration Tool seriously. If you discover a security vulnerability, please follow these steps:

Security vulnerabilities should never be reported through public GitHub issues.

Please email [email protected] with:

• Description of the vulnerability
• Steps to reproduce the issue
• Potential impact
• Any suggested fixes (optional)

• Initial Response: Within 48 hours
• Status Update: Within 5 business days
• Resolution Target: Within 30 days for critical issues

1. Never hardcode credentials in your code

2. Use environment variables or secure vaults:

   config = ToolConfig(
       sap_config={
           "user": os.getenv("SAP_USER"),
           "passwd": os.getenv("SAP_PASSWORD")
       }
   )

3. Rotate credentials regularly

4. Use service accounts with minimal required permissions

Grant only the minimum required authorizations:

• S_RFC: RFC access (required)
• S_TABU_DIS: Table display authorization with specific table groups
• Activity 03 (Display) only, never 02 (Change)

1. Use Secure Connections

   • Enable SNC (Secure Network Communications) when possible
   • Use VPN or private networks for SAP connectivity

2. Firewall Rules

   • Restrict SAP system access to specific IP addresses
   • Use port 3300-3399 only (standard SAP ports)

1. PII Handling

   • The tool can mask sensitive fields automatically
   • Configure in tool_manifest.yaml:

     security:
       data_privacy:
         pii_handling: "mask"

2. Data Encryption

   • Use encryption_level: "enterprise" for sensitive data
   • All cached data is encrypted at rest

3. Audit Logging

   • All data access is logged
   • Review logs regularly for suspicious activity

The tool automatically validates and sanitizes all inputs to prevent:

• SQL injection (though SAP RFC is not vulnerable to traditional SQL injection)
• Command injection
• Path traversal attacks
• Buffer overflow attacks

Configure rate limits to prevent abuse:

config = ToolConfig(
    rate_limit={
        "requests_per_minute": 60,
        "burst_size": 10
    }
)

1. Authentication: SAP RFC authentication required
2. Authorization: Permission checks before data access
3. Encryption: TLS for data in transit
4. Input Validation: All inputs sanitized
5. Rate Limiting: Configurable limits
6. Audit Logging: All operations logged
7. Session Management: Automatic timeout and cleanup

When exposing via REST API, ensure these headers:

X-Content-Type-Options: nosniff
X-Frame-Options: DENY
X-XSS-Protection: 1; mode=block
Strict-Transport-Security: max-age=31536000; includeSubDomains

• Data minimization: Extract only required fields
• Right to erasure: Cache can be cleared on demand
• Data portability: Export in standard formats
• Audit trail: All access is logged

• Read-only access to financial data
• Complete audit trail
• Segregation of duties enforced

Before deploying to production:

• SAP credentials stored securely (not in code)
• Minimal SAP authorizations granted
• Network access restricted
• Encryption enabled
• Rate limiting configured
• Audit logging enabled
• Input validation tested
• Security scan completed
• Penetration testing performed (for critical deployments)

1. PyRFC Library: Keep updated for security patches
2. SAP System: Ensure SAP system has latest security notes applied
3. Dependencies: Regularly update all dependencies

We use the following tools for security:

• Bandit: Static security analysis
• Safety: Dependency vulnerability scanning
• OWASP Dependency Check: Component analysis
• Snyk: Continuous vulnerability monitoring

Run security checks:

# Static analysis
bandit -r sap_r3_integration/

# Dependency scan
safety check

# Full security audit
pre-commit run --all-files security

In case of a security incident:

1. Immediate: Disable affected credentials
2. Within 1 hour: Assess impact and scope
3. Within 24 hours: Notify affected users
4. Within 72 hours: Full incident report
