Which of the following are included in SAP HANA security services?

The inclusion of audit logging in SAP HANA security services is significant because it provides a mechanism to track and record user activities and system events. This capability is essential for maintaining compliance with regulatory requirements and for monitoring the health and security of the database environment. Audit logging helps administrators identify unauthorized access attempts, changes to data, and any anomalies that may indicate security breaches. By utilizing audit logging, organizations can ensure data integrity and security while also enabling a forensic analysis in the event of a security incident.

Other options such as antivirus protection, encryption, and authorization are valid components of overall data security strategies, but they do not specifically fall under the standard SAP HANA security services. Antivirus protection is more closely associated with system-level security rather than database-specific services. Encryption, while crucial for securing data at rest or in transit, is a broader aspect of data protection that may not be directly categorized under HANA's distinct security services. Authorization is involved in managing user permissions and access but does not capture the complete spectrum of security measures that audit logging achieves in terms of tracking and compliance monitoring.
