Importance of securing your SAP S/4HANA System 

According to the recent study, businesses frequently ignore keeping data, processes, and people safe while in the cloud until something goes wrong.

In a report by Onapsis and ASUG titled “Digital Transformation and Security,” 57% of organizations have already completed or are considering SAP S/4HANA migrations. And another 47% of them have switched over to cloud-based technologies already.

In the same poll, 91% of participants agreed that sap security is crucial to the cloud migration of SAP applications.

Unfortunately, more than two-thirds (68.8%) of SAP customers consider that their organizations’ prior SAP implementations did not pay enough attention to IT security. Additionally, 20.8% of SAP clients lack the necessary resources, expertise, and tools.

Before we go any further, let’s take a step and learn about  SAP Security.

What is SAP Security?

SAP Security is a critical component for an enterprise’s cybersecurity strategy, protecting critical SAP business systems that are essential for running core business processes.

SAP Security Considerations When Migrating to the Cloud 

Here are some important considerations to keep in mind when migrating to the cloud:

Data Encryption:

To guard against data theft, data manipulation, and unauthorized access during migration, all data should be encrypted both in transit and at rest.

Identity and Access Management (IAM):

IAM is different in a cloud environment than it is in an on-premise context. Make sure your cloud provider has appropriate IAM policies and practices in place.

Network Security:

VPNs, SSL, and TLS protocols should be used with secure network connections to encrypt network traffic and guard against unauthorized access.

Compliance and Auditing:

In order to prevent infractions, make sure your cloud provider adheres to the necessary compliances and security requirements to avoid violations.

Disaster Recovery and Business Continuity:

To ensure that a data loss does not have an impact on the business, disaster recovery procedures should be in place.

Hence, proper consideration of all the above at the planning stage of the migration can save your business time and money in the long term.

Now, let’s examine how SAP/4HANA security can help solve security problem.

What is SAP S/4HANA Security?

SAP S/4HANA security is protecting important data from unauthorized access and ensures that the standards and compliance meet as security standard adopted by the company. Securing HANA is a critical part of an SAP Security strategy.

10 Key Network and Security Considerations for SAP S/4HANA Implementation

➔ Conducting a security assessment before implementation.

➔ Understanding the security scheme of SAP S/4HANA.

➔ Implementing role-based access control (RBAC) for SAP S/4HANA.

➔ Ensuring secure communications through encryption and secure network configuration.

➔ Implementing network segmentation to reduce the attack surface area.

➔ Importance of regular software updates and patches to mitigate security vulnerabilities.

➔ Importance of monitoring user activities to detect potential security breaches.

➔ Configure firewalls to allow only necessary traffic.

➔ Implementing strong authentication and password policies to reduce the risk of unauthorized access.

➔ Building a disaster recovery plan to ensure business continuity in the event of a security breach or disaster.

By implementing the 10 considerations we have outlined, you can help ensure your SAP S/4HANA implementation is secure and successful.

Now, let’s review top features and provide essential best practices that can help you secure your HANA deployment.

Top SAP HANA Security Features 

• Role-Based Access Control (RBAC)

Role-Based Access Control (RBAC) is a security mechanism that restricts access to system resources based on the roles of individual users within an organization. With RBAC, administrators can define access levels for different roles and assign these roles to individual users.

• SAP HANA Authentication and SSO

SAP HANA supports several authentication mechanisms, including SAML bearer tokens, username/password, Kerberos, and JSON Web tokens.

➔ Basic authentication—allows database-specific  configuration

➔ Kerberos-based authentication—requires mapping database users across all databases to users in the same Key Distribution Center

➔ SAML and JWT-based authentication—allows per-database configuration for JDBC/ODBC client access

• SAP S/4HANA Encryption and  Data Privacy

SAP S/HANA offers encryption capabilities for both deployment types, including communication, backup, and data-at-rest encryption. Both deployment types can integrate with SAP Data Custodian KMS for full control over encryption keys.

Here are key SAP HANA data privacy mechanisms:

➔ Data anonymization— offers real-time data anonymization at the view level, with two methods (differential privacy and k-anonymity) and a custom definition of anonymization views.

➔ Data masking– offers dynamic data masking to protect data at the row level, not replicating it.

• Audit Trail

An audit trail is a record of all system activities that allows administrators to track and review system activity, changes to data, and system events to identify potential security breaches.

• Secure Configuration

SAP S/4HANA has secure configuration features that help prevent unauthorized access to the system. This includes the ability to enforce strong passwords, disable default accounts, and configure security settings.

By leveraging these sap security features, organizations can better protect their data and reduce the risk of security breaches.

Best Practices for Securing SAP HANA 

• Conduct Regular Security Assessments– perform penetration testing and identify vulnerability.
• Implement Role-Based Access Control (RBAC)- restricts access to system resources based on user roles, preventing unauthorized access.
• Enforce Strong Password Policies– create complex passwords with a minimum length and enforce password expiration policies.
• Encrypt Sensitive Data– helps protect sensitive data from unauthorized access or interception.
• Monitor System Logs and Audit Trails– regularly reviewing system logs and audit trails can help detect security breaches and prevent future breaches.
• Keep your System Up-to-Date– regular releases of security patches and updates improve system security.

By following these best practices, organizations can better protect their data and reduce the risk of security incidents.
