Guide to the Secure Configuration of Red Hat Enterprise Linux 8
with profile Protection Profile for General Purpose Operating SystemsThis profile reflects mandatory configuration controls identified in the NIAP Configuration Annex to the Protection Profile for General Purpose Operating Systems (Protection Profile Version 4.2.1). This configuration profile is consistent with CNSSI-1253, which requires U.S. National Security Systems to adhere to certain configuration parameters. Accordingly, this configuration profile is suitable for use in U.S. National Security Systems.

Providing system administrators with such guidance informs them how to securely configure systems under their control in a variety of network roles. Policy makers and baseline creators can use this catalog of settings, with its associated references to higher-level security control catalogs, in order to assist them in security baseline creation. This guide is a catalog, not a checklist, and satisfaction of every item is not likely to be possible or sensible in many operational scenarios. However, the XCCDF format enables granular selection and adjustment of settings, and their association with OVAL and OCIL content provides an automated checking capability. Transformations of this document, and its associated automated checking content, are capable of providing baselines that meet a diverse set of policy objectives. Some example XCCDF Profiles, which are selections of items that form checklists and can be used as baselines, are available with this guide. They can be processed, in an automated fashion, with tools that support the Security Content Automation Protocol (SCAP). The DISA STIG, which provides required settings for US Department of Defense systems, is one example of a baseline created from this guidance.

| Description | To configure the system to lock out accounts after a number of incorrect login
attempts and require an administrator to unlock the account using
unlock_time is set to 0, manual intervention by an administrator is required to unlock a user. |
| Rationale | Locking out user accounts after a number of incorrect attempts prevents direct password guessing attacks. Ensuring that an administrator is involved in unlocking locked accounts draws appropriate attention to such situations. |

| Description | To enable console screen locking, install the $ sudo yum install tmuxInstruct users to begin new terminal sessions with the following command: $ tmuxThe console can now be locked with the following key combination: ctrl+b :lock-session |
| Rationale | A session time-out lock is a temporary action taken when a user stops work and moves away from the immediate
physical vicinity of the information system but does not logout because of the temporary nature of the absence.
Rather than relying on the user to manually lock their operation system session prior to vacating the vicinity,
operating systems need to be able to identify when a user's session has idled and take action to initiate the
session lock.

| Description | Single-user mode is intended as a system recovery
method, providing a single user root access to the system by
providing a boot option at startup. By default, no authentication
is performed if single-user mode is selected.
|
| Rationale | This prevents attackers with physical access from trivially bypassing security on the machine and gaining root access. Such accesses are further prevented by configuring the bootloader password. |

| Description | Red Hat Enterprise Linux 8 systems support an "interactive boot" option that can
be used to prevent services from being started. On a Red Hat Enterprise Linux 8
system, interactive boot can be enabled by providing a systemd.confirm_spawn=(1|yes|true|on)from the kernel arguments in that file to disable interactive boot. It is also required to change the runtime configuration, run: /sbin/grubby --update-kernel=ALL --remove-args="systemd.confirm_spawn" |
| Rationale | Using interactive boot, the console user could disable auditing, firewalls, or other services, weakening system security. |

| Description | To specify password length requirements for new accounts, edit the file
PASS_MIN_LEN 12 The DoD requirement is 15.
The FISMA requirement is 12.
The profile requirement is
12.
If a program consults /etc/login.defs and also another PAM module
(such as pam_pwquality) during a password change operation, then
the most restrictive must be satisfied. See PAM section for more
information about enforcing password quality requirements. |
| Rationale | Requiring a minimum password length makes password cracking attacks more difficult by ensuring a larger search space. However, any security benefit from an onerous requirement must be carefully weighed against usability problems, support costs, or counterproductive behavior that may result. |

| Description | Ensure that loading and unloading of kernel modules is audited. The following rules configure audit as described above: ## These rules watch for kernel module insertion. By monitoring ## the syscall, we do not need any watches on programs. -a always,exit -F arch=b32 -S init_module,finit_module -F key=module-load -a always,exit -F arch=b64 -S init_module,finit_module -F key=module-load -a always,exit -F arch=b32 -S delete_module -F key=module-unload -a always,exit -F arch=b64 -S delete_module -F key=module-unloadThe Audit package provides pre-configured rules in /usr/share/audit/sample-rules. The above content can be found in /usr/share/audit/sample-rules/43-module-load.rules.
To deploy this configuration, it is recommended to copy it over to the /etc/audit/rules.d/ directory:
cp /usr/share/audit/sample-rules/43-module-load.rules /etc/audit/rules.d/Load new Audit rules into kernel by running: augenrules --load |
| Rationale | Loading of a malicious kernel module introduces a risk to the system, as the module has access to sensitive data and perform actions at the operating system kernel level. Having such events audited helps in monitoring and investigating of malicious activities. |

| Description | To ensure the system can cryptographically verify base software packages come from Red Hat (and to connect to the Red Hat Network to receive them), the Red Hat GPG key must properly be installed. To install the Red Hat GPG key, run: $ sudo subscription-manager registerIf the system is not connected to the Internet or an RHN Satellite, then install the Red Hat GPG key from trusted media such as the Red Hat installation CD-ROM or DVD. Assuming the disc is mounted in /media/cdrom, use the following command as the root user to import
it into the keyring:
$ sudo rpm --import /media/cdrom/RPM-GPG-KEYAlternatively, the key may be pre-loaded during the RHEL installation. In such cases, the key can be installed by running the following command: sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release |
| Rationale | Changes to software components can have significant effects on the overall security of the operating system. This requirement ensures the software has not been tampered with and that it has been provided by a trusted vendor. The Red Hat GPG key is necessary to cryptographically verify packages are from Red Hat. |

| Description | To enable FIPS mode, run the following command: fips-mode-setup --enableTo enable FIPS, the system requires that the fips module is added in
dracut configuration.
Check if /etc/dracut.conf.d/40-fips.conf contain add_dracutmodules+=" fips " |
| Rationale | Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The operating system must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. |
| Warnings | warning
The system needs to be rebooted for these changes to take effect. warning
System Crypto Modules must be provided by a vendor that undergoes
FIPS-140 certifications.
FIPS-140 is applicable to all Federal agencies that use
cryptographic-based security systems to protect sensitive information
in computer and telecommunication systems (including voice systems) as
defined in Section 5131 of the Information Technology Management Reform
Act of 1996, Public Law 104-106. This standard shall be used in
designing and implementing cryptographic modules that Federal
departments and agencies operate or are operated for them under
contract. See https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.140-2.pdf
To meet this, the system has to have cryptographic software provided by
a vendor that has undergone this certification. This means providing
documentation, test results, design information, and independent third
party review by an accredited lab. While open source software is
capable of meeting this, it does not meet FIPS-140 unless the vendor
submits to this process. |

System Crypto Modules must be provided by a vendor that undergoes
FIPS-140 certifications.
FIPS-140 is applicable to all Federal agencies that use
cryptographic-based security systems to protect sensitive information
in computer and telecommunication systems (including voice systems) as
defined in Section 5131 of the Information Technology Management Reform
Act of 1996, Public Law 104-106. This standard shall be used in
designing and implementing cryptographic modules that Federal
departments and agencies operate or are operated for them under
contract. See https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.140-2.pdf
To meet this, the system has to have cryptographic software provided by
a vendor that has undergone this certification. This means providing
documentation, test results, design information, and independent third
party review by an accredited lab. While open source software is
capable of meeting this, it does not meet FIPS-140 unless the vendor
submits to this process. |

| Description | The grub2 boot loader should have a superuser account and password
protection enabled to protect boot-time settings.
$ grub2-setpasswordWhen prompted, enter the password that was selected. Once the superuser password has been added, update the grub.cfg file by running:

| Rationale | Password protection on the boot loader configuration ensures users with physical access cannot trivially alter important bootloader settings. These include which kernel to use, and whether to enter single-user mode. |
| Warnings | warning
To prevent hard-coded passwords, automatic remediation of this control is not available. Remediation
must be automated as a component of machine provisioning, or followed manually as outlined above.
Also, do NOT manually add the superuser account and password to the

| Rationale | Source-routed packets allow the source of the packet to suggest routers forward the packet along a different path than configured on the router, which can be used to bypass network security measures. This requirement applies only to the forwarding of source-routerd traffic, such as when IPv6 forwarding is enabled and the system is functioning as a router. Accepting source-routed packets in the IPv6 protocol has few legitimate uses. It should be disabled unless it is absolutely required. |

| Rationale | Routing protocol daemons are typically used on routers to exchange network topology information with other routers. If this capability is used when not required, system network information may be unnecessarily transmitted across the network. |
| Warnings | warning
Certain technologies such as virtual machines, containers, etc. rely on IPv4 forwarding to enable and use networking.
Disabling IPv4 forwarding would cause those technologies to stop working. Therefore, this rule should not be used in
profiles or benchmarks that target usage of IPv4 forwarding. |

| Description | To set the runtime status of the $ sudo sysctl -w net.ipv4.conf.default.accept_redirects=0To make sure that the setting is persistent, add the following line to a file in the directory /etc/sysctl.d: net.ipv4.conf.default.accept_redirects = 0 |
| Rationale | ICMP redirect messages are used by routers to inform hosts that a more
direct route exists for a particular destination. These messages modify the
host's route table and are unauthenticated. An illicit ICMP redirect
message could result in a man-in-the-middle attack.

| Description | To set the runtime status of the $ sudo sysctl -w net.ipv4.conf.default.log_martians=1To make sure that the setting is persistent, add the following line to a file in the directory /etc/sysctl.d: net.ipv4.conf.default.log_martians = 1 |
| Rationale | The presence of "martian" packets (which have impossible addresses) as well as spoofed packets, source-routed packets, and redirects could be a sign of nefarious network activity. Logging these packets enables this activity to be detected. |

| Rationale | Enabling reverse path filtering drops packets with source addresses that should not have been able to be received on the interface they were received on. It should not be used on systems which are routers for complicated networks, but is helpful for end hosts and routers serving small networks. |

| Rationale | Source-routed packets allow the source of the packet to suggest routers
forward the packet along a different path than configured on the router,
which can be used to bypass network security measures. This requirement
applies only to the forwarding of source-routerd traffic, such as when IPv4
forwarding is enabled and the system is functioning as a router.

| Description |
To configure the system to prevent the install cramfs /bin/trueThis effectively prevents usage of this uncommon filesystem. The cramfs filesystem type is a compressed read-only
Linux filesystem embedded in small footprint systems. A
cramfs image can be used without having to first
decompress the image. |
| Rationale | Removing support for unneeded filesystem types reduces the local attack surface of the server. |

| Description | To set the runtime status of the $ sudo sysctl -w user.max_user_namespaces=0To make sure that the setting is persistent, add the following line to a file in the directory /etc/sysctl.d:
user.max_user_namespaces = 0When containers are deployed on the machine, the value should be set to large non-zero value. |
| Rationale | User namespaces are used primarily for Linux containers. The value 0 disallows the use of user namespaces. |

This configuration baseline was created to deploy the base operating system for general purpose
workloads. When the operating system is configured for certain purposes, such as to host Linux Containers,
it is expected that user.max_user_namespaces will be enabled. |

| Description | The root user should never be allowed to login to a
system directly over a network.
To disable root login via SSH, add or correct the following line
in PermitRootLogin no |
| Rationale | Even though the communications channel may be encrypted, an additional layer of security is gained by extending the policy of not logging directly on as root. In addition, logging in with a user-specific account provides individual accountability of actions performed on the system and also helps to minimize direct attack attempts on root's password. |

| Description | To explicitly disallow SSH login from accounts with
empty passwords, add or correct the following line in PermitEmptyPasswords no Any accounts with empty passwords should be disabled immediately, and PAM configuration should prevent users from being able to assign themselves empty passwords. |
| Rationale | Configuring this setting for the SSH daemon provides additional assurance that remote login via SSH will require a password, even in the event of misconfiguration elsewhere. |

| Description | To set up SSH server to use entropy from a high-quality source, edit the SSH_USE_STRONG_RNG=32 |
| Rationale | SSH implementation in RHEL8 uses the openssl library, which doesn't use high-entropy sources by default. Randomness is needed to generate data-encryption keys, and as plaintext padding and initialization vectors in encryption algorithms, and high-quality entropy elliminates the possibility that the output of the random number generator used by SSH would be known to potential attackers. |
| Warnings | warning
This setting can cause problems on computers without the hardware random generator, because insufficient entropy causes the connection to be blocked until enough entropy is available. |

| Rationale | Kerberos authentication for SSH is often implemented using GSSAPI. If Kerberos is enabled through SSH, the SSH daemon provides a means of access to the system's Kerberos implementation. Vulnerabilities in the system's Kerberos implementations may be subject to exploitation. |

| Description | SSH allows administrators to set an idle timeout interval. After this interval
has passed, the idle user will be automatically logged out.
ClientAliveInterval 840 The timeout interval is given in seconds. For example, have a timeout of 10 minutes, set interval to 600. If a shorter timeout has already been set for the login shell, that value will preempt any SSH setting made in /etc/ssh/sshd_config. Keep in mind that
some processes may stop SSH from correctly detecting that the user is idle. |
| Rationale | Terminating an idle ssh session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been let unattended. |

| Description | Unless needed, SSH should not permit extraneous or unnecessary
authentication mechanisms like GSSAPI. To disable GSSAPI authentication, add or
correct the following line in the GSSAPIAuthentication no |
| Rationale | GSSAPI authentication is used to provide additional authentication mechanisms to applications. Allowing GSSAPI authentication through SSH exposes the system's GSSAPI to remote hosts, increasing the attack surface of the system. |

| Description | To allow authorization of USB devices combining human interface device and hub capabilities
by USBGuard daemon,
add the line
|
| Rationale | Without allowing Human Interface Devices, it might not be possible to interact with the system. Without allowing hubs, it might not be possible to use any USB devices on the system. |
| Warnings | warning
This rule should be understood primarily as a convenience administration feature. This rule ensures that if the USBGuard default rules.conf file is present, it will alter it so that USB human interface devices and hubs are allowed. However, if the rules.conf file is altered by system administrator, the rule does not check if USB human interface devices and hubs are allowed. This assumes that an administrator modified the file with some purpose in mind. |
