Explanation
These are some of the characteristics of an SAP HANA multitenant database system (MDC) running in high isolation mode. MDC is a feature that allows you to run multiple databases on one SAP HANA system, each with its own users, catalog, repository, data, and services. High isolation mode is a mode that provides enhanced security and isolation for tenant databases by restricting access to files and directories at the operating system level. In high isolation mode, all tenant-specific permissions to access files and directories are revoked from the <sid>adm user, which is the operating system user for SAP HANA administration. All tenant-specific file and directory permissions are managed by the SAP HANA system using internal users and groups. References: https://help.sap.com/viewer/6b94445c94ae495c83a1

Explanation
These are some of the measures that should be implemented to protect the PSEs (Personal Security Environments). PSEs are files that store cryptographic information, such as keys and certificates, for various security purposes, such as SSL, SNC, or SSO. The usage of the S_ADMI_FCD object should be reviewed because it controls the access to PSE administration functions, such as creating, deleting, or displaying PSEs.
The access to the operating system users should be restricted because they can access the PSE files directly from the file system and manipulate them. References:

Explanation
These are some of the purposes for which we use instance Secure Storage File System (SSFS) in an SAP HANA system. SSFS is a feature that enables secure and encrypted storage of sensitive data and files in SAP HANA systems, such as passwords, keys, or certificates. SSFS can store root keys for data volume encryption, which are keys that are used to encrypt and decrypt data volumes in SAP HANA systems. SSFS can also protect the password of the root key backup, which is a password that is used to backup and restore root keys in case of system failure or migration. References:

Explanation
The purpose of the parameter rec/client in an AS ABAP based SAP system is to log changes in tables that are marked as change-relevant in transaction SE11 (ABAP Dictionary). The parameter rec/client specifies which clients are affected by table logging. References:

Explanation
Source and Service Provider are two types of systems that can be found in the Identity Provisioning Service landscape. A source system is a system that provides user data to be provisioned to other systems, such as an identity provider or an LDAP server. A service provider system is a system that receives user data from a source system, such as an SAP Cloud Platform subaccount or an SAP SuccessFactors instance. References:
