Security hardening aims to enhance the defense capabilities of the Operating system.

Security hardening has the following functions on the eSight server:

  • Disable unnecessary system services on eSight to reduce the possibility of malicious attacks.
  • Strictly restrict the file permission and environment variables of the system to reduce the possibility of unauthorized operations.

Security Hardening Objects

The primary objects of security hardening are the operating system.

Table 2-11 Security hardening objects



SUSE Linux operating system


Security Hardening Scenarios

After services are installed, commissioned, upgraded, backed up, and restored, you need to perform security hardening on the OS. If security hardening has been performed on the OS, you must roll back the security hardening before uninstallation.

Table 2-12 Security Hardening Scenarios




Security hardening

After installation and commissioning

After each component is installed and commissioned, security hardening must be performed for the system where the component runs to enhance system security.

After an upgrade

After each component version is upgraded, security hardening must be performed for the system where the component runs to enhance system security.


Before uninstallation

Before uninstallation, if the operating system has been hardened, roll back the security hardening. Otherwise, the uninstallation may fail.

The hardening is invalid for existing sessions. After the hardening, quit all the sessions and connect them again.

After the security of a SUSE Linux operating system is hardened, certain parameters and user permission settings are changed.

For details, see descriptions in the hardening policy package.


After the SUSE operating system is hardened, to remotely log in to the server on an Xshell terminal, use Xshell 5 or a later version.

After the security hardening, some hardening items of the SUSE operating system cannot be rolled back. For details, see Table 2-14.


After the security of a database is hardened, certain parameters and user permission are changed.
