SRG-OS-000134-GPOS-00068
Group -
RHEL 8 must disable virtual syscalls.
Syscalls are special routines in the Linux kernel, which userspace applications ask to do privileged tasks. Invoking a system call is an expensive operation because the processor must interrupt th...Rule Medium Severity -

Group -
YUM must remove all software components after updated versions have been installed on RHEL 8.
Previous versions of software components that are not removed from the information system after updates have been installed may be exploited by adversaries. Some information technology products may...Rule Low Severity -
SRG-OS-000445-GPOS-00199
Group -
RHEL 8 must enable the SELinux targeted policy.
Without verification of the security functions, security functions may not operate correctly and the failure may go unnoticed. Security function is defined as the hardware, software, and/or firmwar...Rule Medium Severity -
SRG-OS-000480-GPOS-00227
Group -
There must be no shosts.equiv files on the RHEL 8 operating system.
The "shosts.equiv" files are used to configure host-based authentication for the system via SSH. Host-based authentication is not sufficient for preventing unauthorized access to the system, as it ...Rule High Severity -

There must be no .shosts files on the RHEL 8 operating system.
The ".shosts" files are used to configure host-based authentication for individual users or the system via SSH. Host-based authentication is not sufficient for preventing unauthorized access to the...Rule High Severity -
SRG-OS-000480-GPOS-00227
Group -
RHEL 8 must enable the hardware random number generator entropy gatherer service.
The most important characteristic of a random number generator is its randomness, namely its ability to deliver random numbers that are impossible to predict. Entropy in computer security is associ...Rule Low Severity -
SRG-OS-000480-GPOS-00227
Group -
The RHEL 8 SSH public host key files must have mode 0644 or less permissive.
If a public host key file is modified by an unauthorized user, the SSH service may be compromised.Rule Medium Severity -
SRG-OS-000480-GPOS-00227
Group -
The RHEL 8 SSH private host key files must have mode 0640 or less permissive.
If an unauthorized user obtains the private SSH host key file, the host could be impersonated.Rule Medium Severity -
SRG-OS-000480-GPOS-00227
Group -
The RHEL 8 SSH daemon must perform strict mode checking of home directory configuration files.
If other users have access to modify user-specific SSH configuration files, they may be able to log on to the system as another user.Rule Medium Severity -
SRG-OS-000480-GPOS-00227
Group -
The RHEL 8 SSH daemon must not allow authentication using known host’s authentication.
Configuring this setting for the SSH daemon provides additional assurance that remote logon via SSH will require a password, even in the event of misconfiguration elsewhere.Rule Medium Severity -
SRG-OS-000480-GPOS-00227
Group -
The RHEL 8 SSH daemon must not allow Kerberos authentication, except to fulfill documented and validated mission requirements.
Configuring these settings for the SSH daemon provides additional assurance that remote logon via SSH will not use unused methods of authentication, even in the event of misconfiguration elsewhere.Rule Medium Severity -
SRG-OS-000480-GPOS-00227
Group -
RHEL 8 must use a separate file system for /var.
The use of separate file systems for different paths can protect the system from failures resulting from a file system becoming full or failing.Rule Low Severity -

RHEL 8 must not permit direct logons to the root account using remote access via SSH.
Even though the communications channel may be encrypted, an additional layer of security is gained by extending the policy of not logging on directly as root. In addition, logging on with a user-sp...Rule Medium Severity -

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
