Which method is typically used to ensure data security in SAP HANA?

The method of ensuring data security by encrypting data both at rest and in transit is essential because it protects sensitive information from unauthorized access and data breaches. Encryption at rest ensures that data stored in the HANA database is protected by converting it into a format that is unreadable without the proper decryption key. This means that even if an attacker gains physical access to the storage media or database, they cannot interpret the data without the associated keys.

Similarly, encrypting data in transit safeguards information as it moves between clients and the database. This is crucial for preventing eavesdropping and man-in-the-middle attacks, where an unauthorized entity could intercept the data during its transmission network. By encrypting both at rest and in transit, SAP HANA provides a robust framework for data security, ensuring comprehensive protection across all stages of data handling.

The other methods mentioned, while they may play a role in a broader security strategy, do not provide the same level of assurance when it comes to protecting data. Limiting user access can help to control who can see specific pieces of data but does not encrypt the data itself. Using public Wi-Fi networks poses significant security risks and doesn’t inherently provide any security for data transfers. Lastly, while end-user training is important for
