Additionally, SUSE Linux Enterprise Server for SAP Applications ships with a YaST wizard that simplifies the cluster setup.

The installation workflow offers a guided installation path for both the SUSE Linux Enterprise Server operating system and the SAP application. This workflow can be extended by third-party vendors using Supplementary Media. For more information, see Section 2.4, “Overview of the installation workflow”.

Malware protection with ClamSAP

ClamSAP integrates the ClamAV anti-malware toolkit into SAP NetWeaver and SAP Mobile Platform applications to enable cross-platform threat detection.

SAP HANA firewall and SAP HANA hardening guide

SUSE Linux Enterprise Server for SAP Applications additionally provides the package HANA-Firewall which integrates with firewalld to provide a preconfigured setup and rules to make securing SAP HANA as simple as possible.

For information on hardening the underlying operating system, see the SUSE Linux Enterprise Server for SAP Applications resource library: https://www.suse.com/products/sles-for-sap/resource-library/. There, find the document OS Security Hardening for SAP HANA.

Simplified operations management

cryptctl allows encrypting sensitive directories using LUKS. Encryption keys are located on a central server which can be located on customer premises. Encrypted partitions are automatically remounted after an unplanned reboot.

To simplify working with software dependencies of SAP applications, SUSE has created patterns that combine relevant dependency RPM packages for specific applications.

ClusterTools2 provides tools that help set up and manage a Corosync/pacemaker cluster.
