3 Best Practices for Securing Your SAP HANA

March 17, 2021

Security has become an essential factor in any technology, and it should not be compromised at all. SAP Security is a field that combines several distinct elements of cybersecurity, ranging from access control to application-level security to data protection. SAP HANA (SAP High-Performance Analytic Appliance) is a column-oriented in-memory database that runs advanced analytics alongside high-speed transactions – in a single system. The in-memory computing engine allows HANA to process data stored in RAM instead of reading it from a disk. That’s the main reason it can process immense data with almost zero latency, provide instant query results, and takes strategic decisions based on data analysis and interpretation. So, SAP HANA most importantly requires security on user control, the integrity of data fed on a database, and user authentication.

Here are Some of the Best SAP HANA Security Practices

Adopt the Principle of Least Privilege

As we already have sensed the damages that can create to an organization through excessive user authority, we must keep in mind practicing the principle of least or minimal authority in SAP HANA Security. The less access is given to the employee, the more data security and less risk of insider threats. SAP deals with all the ERP and finance, CRM and customer experience, database, network, supply chain, business technology platform, and-so-on. SAP HANA security must restrict each user with permission based on their roles. Even a simple bill of products for an upcoming project can provide the biggest hint to their business challenger that can lead to a very competitive market. Hence, the least access authority can save any organization from attackers accessing the critical system or sensitive information.

Understand the Power of Web IDE for SAP HANA

SAP GUI has become very easy for all users to interact and access data throughout the SAP applications. However, SAP HANA has a privilege system that gives users direct access to the databases using SAP Web IDE. It is a browser-based IDE for the development of SAP HANA-based applications comprised of web-based or mobile UIs, business logic, and extensive SAP HANA data models. SAP Web IDE relies on SAP Cloud Platform infrastructure for authentication and authorization and checks with different systems like SAP Gateway, user workspace, Git and then allows secure connectivity.

Implement Data Encapsulation or Anonymization Technique

It is an excellent technique to hide the original data with some modified content. This allows access to data to users based on their roles. This way we can protect information like personally identifiable information, sensitive personal data, or business-sensitive data. SAP has built-in security features that allow performing data masking, anonymization, and encapsulation. Anonymization mainly focuses on data privacy so that the key identifying information remains anonymous. Using these methods can prevent security breaches of data.
