By default, the sha512 option is added to the NORMAL ruleset in AIDE. If using a custom ruleset or the sha512 option is missing, add sha512 to the appropriate ruleset. For example, add sha512 to the following line in /etc/aide.conf:
NORMAL = FIPSR+sha512AIDE rules can be configured in multiple ways; this is merely one example that is already configured by default.
File integrity tools use cryptographic hashes for verifying file contents and directories have not been altered. These hashes must be FIPS 140-2 approved cryptographic hashes.
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 "
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.
To enable FIPS mode, run the following command:
fips-mode-setup --enable
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.
On a system where FIPS mode is enabled, /etc/system-fips must exist. To enable FIPS mode, run the following command:
fips-mode-setup --enable
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.
To ensure FIPS mode is enabled, install package dracut-fips, and rebuild initramfs by running the following commands:
$ apt-get install dracut-fips dracut -fAfter the dracut command has been run, add the argument fips=1 to the default GRUB 2 command line for the Linux operating system in /etc/default/grub, in the manner below:
GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=VolGroup/LogVol06 rd.lvm.lv=VolGroup/lv_swap rhgb quiet rd.shell=0 fips=1"Finally, rebuild the grub.cfg file by using the
grub2-mkconfig -ocommand as follows:
~]# grub2-mkconfig -o /boot/grub/grub.cfg
~]# grub2-mkconfig -o /boot/grub/grub.cfg
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.
On a system where FIPS 140-2 mode is enabled, /proc/sys/crypto/fips_enabled must exist. To verify FIPS mode, run the following command:
cat /proc/sys/crypto/fips_enabled
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.
To enable FIPS on system that support the Advanced Encryption Standard (AES) or New
Instructions (AES-NI) engine, the system requires that the dracut-fips-aesni
package be installed.
The dracut-fips-aesni package can be installed with the following command:
$ apt-get install dracut-fips-aesni

By default, the SELinux boolean fips_mode is enabled.
This allows all SELinux domains to execute in fips_mode.
If this setting is disabled, it should be enabled.
To enable the fips_mode SELinux boolean, run the following command:
$ sudo setsebool -P fips_mode on
System running in FIPS mode is indicated by kernel parameter 'crypto.fips_enabled'. This parameter should be set to 1 in FIPS mode. To enable FIPS mode, run the following command:
fips-mode-setup --enableTo enable strict FIPS compliance, the fips=1 kernel option needs to be added to the kernel boot parameters during system installation so key generation is done with FIPS-approved algorithms and continuous monitoring tests in place.
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.
