SAP HANA security services include which of the following?

Audit logging is indeed one of the key features of SAP HANA security services. It involves tracking and recording user activities and system changes for compliance and security monitoring purposes. This feature helps organizations ensure that they are following best practices and regulatory requirements by maintaining a detailed record of who accessed the system, when they did so, and what actions they performed. Audit logging plays a crucial role in identifying suspicious activities, providing insights for security analysts, and supporting incident investigations.

While antivirus protection, encryption, and authorization are important aspects of overall system security, they do not specifically refer to the distinct audit logging capability within SAP HANA's security services framework. Antivirus protection typically falls under endpoint security measures rather than database-level security, encryption is a method to secure data at rest or in transit but is not an auditing capability, and while authorization is critical for managing user access, it does not involve the logging of activities like audit logging does. This emphasizes the unique role that audit logging plays in ensuring the integrity and security of an SAP HANA environment.
