Chapter 3. Security and SAP Solutions

Enterprises usually have substantial compliance requirements based on the industry, type of customers, geographic location, and more. Such requirements might need specific certifications, cryptographic modules, and support for encryptions. With Red Hat Enterprise Linux for SAP Solutions, Red Hat delivers a stable, security-focused, high-performance foundation for SAP business applications to support such requirements and provide an easy way to set and validate compliance policies.

You can learn about processes and practices for securing Red Hat Enterprise Linux systems against local and remote intrusion, exploitation, and malicious activity. These approaches and tools can create a more secure environment for running SAP HANA.

3.1. SELinux for SAP production environments

SELinux is a security technology for process isolation to mitigate attacks via privilege escalation. Configuring SELinux helps you enhance your system’s security. SELinux is an implementation of Mandatory Access Control (MAC), and provides an additional layer of security. The SELinux policy defines how users and processes can interact with the files on the system. You can control which users can perform which actions by mapping them to specific SELinux confined users.

3.2. File Access Policy Daemon (fapolicyd)

File Access Policy Daemon (fapolicyd) is a technology provided in RHEL to determine access rights to files based on a trust database and file or process attributes. It helps customers to ensure data remains protected even in case an attacker has successfully gained control over certain processes.

You can configure fapolicyd to secure the environment for running SAP HANA against local and remote intrusion, exploitation, and malicious activity.
