Comprehensive Guide: SAP HANA Security Settings for Cybersecurity Compliance

To ensure SAP HANA complies with cybersecurity standards, especially in environments requiring strict adherence to regulations, you must configure it with security best practices. Below are technical settings and configurations for securing SAP HANA, focusing on access control, data protection, network security, and monitoring for comprehensive cybersecurity compliance.

1. Authentication and Access Control

NIST Control Reference: AC-2, AC-3 (Access Control)

• User Authentication: Ensure that SAP HANA uses strong authentication methods, including X.509 certificates, SAML, and LDAP integration for centralized identity management.
• Password Policies: Enforce strong password rules in HANA (minimum length, complexity, expiration). This can be done using SQL commands:
• Role-Based Access Control (RBAC): Configure roles and privileges based on the principle of least privilege. Use predefined roles (such as SYS_ADMIN and DB_ADMIN) and create custom roles for specific functions.
• Two-Factor Authentication (2FA): Integrate 2FA for sensitive access using third-party solutions or SAP’s native support for strong authentication.

2. Data Encryption

NIST Control Reference: SC-12, SC-13 (Cryptographic Key Establishment and Management)

• Data Encryption at Rest:Enable Transparent Data Encryption (TDE) for encrypting database data at rest. In HANA, you can set up data volume encryption by using:
• Encryption in Transit:Ensure all client and application communication with HANA is encrypted using SSL/TLS. Configure network encryption for external communication:

3. Auditing and Monitoring

NIST Control Reference: AU-2, AU-6 (Audit Events)

• Enable Auditing: Activate SAP HANA’s built-in audit log to track login attempts, data access, and system changes. Configure audit policies in global.ini:
• Real-Time Monitoring: Implement SAP Solution Manager or third-party SIEM solutions for real-time logging, monitoring, and alerting. Ensure that logs are securely stored and periodically reviewed for anomalies.
• Intrusion Detection and Prevention: Integrate SAP HANA with intrusion detection systems (IDS) to monitor network traffic and detect unauthorized access.

4. Network Security

NIST Control Reference: SC-7 (Boundary Protection)

• Network Isolation: Place SAP HANA behind a firewall and in a DMZ (Demilitarized Zone) or VPC (Virtual Private Cloud) to limit inbound and outbound access to only trusted IPs.
• Secure Communication Protocols: Use SSL/TLS for all communication protocols, including JDBC, ODBC, and HTTP. Disable unused protocols to reduce the attack surface.
• Port Security: Restrict access to essential SAP HANA services and ports, such as ports 30015 and 30041. Block non-essential ports using a firewall.
• VPN Access: Ensure remote administrators access SAP HANA only via a secure VPN connection to safeguard external access.

5. Data Masking and Anonymization

NIST Control Reference: SC-28 (Protection of Information at Rest)

• Data Masking: For sensitive customer or financial data, implement data masking to ensure personally identifiable information (PII) is not exposed in non-production environments.
• Data Anonymization: Use anonymization techniques when handling sensitive data for analytics or reporting. SAP HANA offers built-in data anonymization capabilities, such as generalization and differential privacy, to ensure compliance with privacy regulations.

6. Patching and Vulnerability Management

NIST Control Reference: SI-2 (Flaw Remediation)

• Regular Patch Updates: Apply SAP HANA Security Notes and patches regularly. Schedule maintenance windows to update the HANA database with the latest security fixes.
• Vulnerability Scanning: Use SAP EarlyWatch Alert services and third-party vulnerability scanners to identify and address weaknesses in SAP HANA and related infrastructure.

7. Backup and Disaster Recovery

NIST Control Reference: CP-9 (System Backup), CP-10 (Recovery Procedures)

• Secure Backup Solutions: Ensure that backups are encrypted and stored securely. Use Backint for HANA and ensure encryption keys for backup files are managed properly.
• Test Disaster Recovery Plans: Regularly test disaster recovery plans (DRP) and ensure that backups are recoverable. Validate recovery procedures to ensure continuity of operations in case of a cyber attack.

8. Application Security

NIST Control Reference: SA-3, SA-11 (System and Services Acquisition)

• Secure Development Lifecycle (SDLC): Implement a secure development lifecycle for any custom applications using SAP HANA, ensuring they follow OWASP best practices.
• Code Vulnerability Scanning: Use SAP’s Code Vulnerability Analyzer or third-party tools to scan custom code for security vulnerabilities and ensure the use of secure coding practices.

Conclusion

By configuring SAP HANA with the above security settings, you can achieve a robust level of cybersecurity compliance. These settings are aligned with NIST SP 800-53 controls, ensuring both data protection and system integrity, which is critical for compliance with cybersecurity regulations such as GDPR, HIPAA, and ISO 27001.
