Security Tools

Security is another important consideration, whether you manage a home network or a corporate colossus with 50,000 nodes. openEuler users can access all the powerful security components that populate the enterprise Linux space, and the openEuler developers highlight a few additional components that have received special attention.

The Integrity Management Architecture (IMA) is a mandatory access control subsystem built into Linux kernel 2.6 or later. IMA provides a deep level of file integrity protection, ensuring that boot files, system files, and other critical file assets are not subject to unauthorized change. IMA digest lists create a chain of trust that ensures processes operate without compromise.

SysMaster is an ultra-light, fault-monitoring, self-recovering replacement for the conventional init process that improves reliability and service availability without the complexity and long learning curve of systemd. open-Euler also provides support for secGear, a secure application development kit, and secPaver, a tool for developing SELinux mandatory access control policies.

Desktop

When you first install openEuler, it lands you at the command prompt. The openEuler OS is used in a variety of server settings and is designed for efficiency, without assuming the need for a full desktop environment. If you are setting up openEuler on a user workstation, or if you prefer a GUI environment to the command prompt, the openEuler documentation describes the steps for installing a desktop environment. openEuler supports the Gnome, Xfce, DDE, and UKUI desktops.

Devices and Things

OpenHarmony is an OS used with embedded systems, smartphones, tablets, Internet of Things devices, and other systems. The OpenHarmony OS was also developed by Huawei and is maintained by the OpenAtom Foundation. openEuler is closely integrated with OpenHarmony (as shown in Figure 2), offering seamless compatibility with a wide range of popular devices. The openEuler community also supports a number of other tools and systems for embedded development, as well as tools for interfacing with smartphones and other smart devices. The community even maintains a version of openEuler that runs on Raspberry Pi systems.
