1. Introduction
1.1 Overview
This document is the Security Policy for the Oracle Linux 7 OpenSSH Server Cryptographic Module by Oracle
Corporation. Oracle Linux 7 OpenSSH Server Cryptographic Module is also referred to as “the Module” or
“Module”. This Security Policy specifies the security rules under which the module shall operate to meet the
requirements of FIPS 140-2 Level 1. It also describes how the Oracle Linux 7 OpenSSH Server Cryptographic
Module functions in order to meet the FIPS 140-2 requirements, and the actions that operators must take to
maintain the security of the module.
This Security Policy describes the features and design of the Oracle Linux 7 OpenSSH Server Cryptographic Module
using the terminology contained in the FIPS 140-2 specification. FIPS 140-2, Security Requirements for
Cryptographic Module specifies the security requirements that will be satisfied by a cryptographic module utilized
within a security system protecting sensitive but unclassified information. The NIST/CCCS Cryptographic Module
Validation Program (CMVP) validates cryptographic module to FIPS 140-2. Validated products are accepted by the
Federal agencies of both the USA and Canada for the protection of sensitive or designated information.
1.2 Document Organization
The FIPS 140-2 submission package contains:
• Oracle Linux 7 OpenSSH Server Cryptographic Module Non-Proprietary Security Policy

3. Cryptographic Module Specification
3.1 Definition of the Cryptographic Module
The Oracle Linux 7 OpenSSH Server Cryptographic Module is a software-only multi-chip standalone module as
defined by the requirements within FIPS PUB 140-2. The logical cryptographic boundary of the module consists of
the application, library files and their integrity check HMAC files, which are delivered through the Oracle Linux
Yum Public Server as listed below:
The module will use the Oracle Linux OpenSSL Cryptographic Module (FIPS 140-2 Certificate #3474) as a bound
module which provides the underlying cryptographic algorithms necessary for establishing and maintaining the
SSH session. In addition the integrity check uses the cryptographic services provided by the Oracle Linux OpenSSL
Cryptographic Module as used by the utility application of fipscheck using the HMAC-SHA-256 algorithm.
This requires a copy of a Cert. #3474 validated version of the Oracle Linux OpenSSL Cryptographic Module to be
installed on the system for the current module to operate.
The cryptographic Module combines a vertical stack of Oracle Linux components intended to limit the external
interface each separate component may provide. The following software needs to be installed for the module to
operate:
• Oracle Linux 7 OpenSSH Server Cryptographic Module with the version of the OpenSSH server RPM file
openssh-server-7.4p1-16.el7.x86_64.rpm
• The bound module of OpenSSL with FIPS 140-2 Certificate #3474
• The contents of the fipscheck RPM package (version 1.4.1-6.el7.x86_64)
• The contents of the fipscheck-lib RPM package (version 1.4.1-6.el7.x86_64).
The OpenSSH server RPM package of the Module includes the binary files, integrity check HMAC files and Man
Pages. Any application other than the OpenSSH server application delivered with the aforementioned OpenSSH
RPM packet is not part of the Module. The FIPS certificate for this module will not be valid if any other
application than the OpenSSH server application is used.
The files comprising the module are the following:
• /usr/sbin/sshd
• /usr/bin/fipscheck
• /usr/lib64/fipscheck/sshd.hmac
• /usr/lib64/fipscheck/fipscheck.hmac
• /usr/lib64/fipscheck/libfipscheck.so.1.2.1.hmac
• /usr/lib64/libfipscheck.so.1.2.1
Figure 1 shows the logical block diagram of the module executing in memory on the host system.

Figure 1: Oracle Linux 7 OpenSSH Server Logical Cryptographic Boundary
3.2 Definition of the Physical Cryptographic Boundary
The physical cryptographic boundary is defined as the hard enclosure of the host system on which it runs. See
Figure 2 below. No components are excluded from the requirements of FIPS PUB 140-2.

3.3 Modes of Operation
The Module supports two modes of operation: FIPS approved and non-FIPS approved mode. The mode of
operation is implicitly assumed depending on the services/security functions invoked. The Module turns to the
FIPS approved mode after power-on self-tests succeed. The services available in FIPS mode can be found in
section 7.2, Table 10.
3.4 Approved Security Functions from OpenSSH module
The Oracle Linux 7 OpenSSH Server Cryptographic Module contains the following FIPS Approved Algorithms:
Approved or Allowed Security Functions Certificate

Table 9: Vendor Affirmed Operating Environment
CMVP makes no statement as to the correct operation of the module or the security strengths of the generated
keys when ported if the specific operational environment is not listed on the validation certificate.
6.3 Operational Environment Policy
The operating system is restricted to a single operator (concurrent operators are explicitly excluded). The entity
using the application is the single user of the module. In FIPS Approved mode, the ptrace(2) system call, the
debugger (gdb(1)), and strace(1) shall be not used.

Table 12: CSP Table
8.1 Random Number and Key Generation
The module does not implement any random number generator nor does it provide key generation. The module
only provides key derivation through the implementation of the SP 800-135 KDF.
When establishing the SSH Session, the module calls the bound OpenSSL module which generates the shared
secret. The module derives keys from this shared secret by applying SP 800-135 KDF. When the module requests
encryption/decryption services provided by the OpenSSL bound module, the resulting derived symmetric key (i.e.
the output of the SP 800-135 KDF) will be passed to the OpenSSL bound module via API parameters. The module
does not support manual key entry.
2
According to IG A.13, the same Triple-DES key shall not be used to encrypt more than 2^20 64-bit blocks of data.
Oracle Linux 7 OpenSSH Server Cryptographic Module Security Policy
Page 17 of 25
8.2 Key/CSP Storage
The module does not perform persistent storage of keys. The keys and CSPs are temporarily stored as plaintext in
the RAM. The server’s public and private keys are stored in the host key files in /etc/ssh directory, which are
outside its logical boundary.
8.3 Key/CSP Zeroization
The destruction functions overwrite the memory occupied by keys with zeros and deallocates the memory with
the free () call. In case of abnormal termination, or swap in/out of a physical memory page of a process, the keys
in physical memory are overwritten before the physical memory is allocated to another process.
Oracle Linux 7 OpenSSH Server Cryptographic Module Security Policy
Page 18 of 25
9. Self-Tests
9.1 Power-Up Self-Tests
The module performs power-up self-tests at module initialization to ensure that the module is not corrupted. The
self-tests are automatically triggered without any user intervention.
While the module is performing the power-up tests, services are not available, and input or output data is not
possible: the module is not available for use until the self-tests are completed successfully.
9.1.1 Integrity Tests
The integrity check is performed by the fipscheck application using the HMAC-SHA-256 algorithm implemented by
the bound Oracle Linux OpenSSL Cryptographic Module. When the OpenSSH module starts, it triggers the power-
on self-tests which includes the software integrity test.
The user space integrity verification is performed as follows: the OpenSSH Server application links with the library
libfipscheck.so which is intended to execute fipscheck to verify the integrity of the OpenSSH server application file
using the HMAC-SHA-256 algorithm. Upon calling the FIPSCHECK_verify() function provided with libfipscheck.so,
fipscheck is loaded and executed, and the following steps are performed:
1. OpenSSL, loaded by fipscheck, performs the integrity check of the OpenSSL library files using the HMAC-
SHA-256 algorithm
2. fipscheck performs the integrity check of its application file using the HMAC-SHA-256 algorithm provided by
the OpenSSL Module
3. fipscheck automatically verifies the integrity of libfipscheck.so before processing requests of calling
applications
4. The fipscheck application performs the integrity check of the OpenSSH server application file. The fipscheck
computes the HMAC-SHA-256 checksum of that and compares the computed value with the value stored
inside the /usr/lib64/fipscheck/<applicationfilename>.hmac checksum file. The fipscheck application
returns the appropriate exit value based on the comparison result: zero if the checksum is OK, an error code
otherwise (which brings the OpenSSH Module into the error state). The libfipscheck.so library reports the
result to the OpenSSH server application.
If any of those steps fail, an error code is returned and the OpenSSH Module enters the error state with the
message ‘FIPS integrity verification test failed’. In Error state, all data output is inhibited and no cryptographic
operation is allowed. The module needs to be reloaded in order to recover from the Error state.
9.1.2 Cryptographic Algorithm Tests
The OpenSSH module will use the Oracle Linux OpenSSL Cryptographic Module as a bound module which provides
the underlying cryptographic algorithms. All the known answer tests are implemented by the bound OpenSSL
Module.
9.2 On-Demand self-tests
The module provides the Self-Test service to perform self-tests on demand. On demand self-tests can be invoked
by powering-off and reloading the module. This service performs the same tests executed during power-up.
During the execution of the on-demand self-tests, crypto services are not available and no data output or input is
possible.
Oracle Linux 7 OpenSSH Server Cryptographic Module Security Policy
Page 19 of 25
10. Crypto-Officer and User Guidance
The following guidance items are to be used for assistance in maintaining the module's validated status while in
use.
10.1 Crypto-Officer Guidance
The version of the RPM file containing the FIPS validated Module is stated in section 3.1 above. The Oracle Linux
OpenSSL Cryptographic Module referenced in section 3.1 must be installed according to its Security Policy.
The RPM package of the Module can be installed by standard tools recommended for the installation of Oracle
packages on an Oracle Linux system (for example, yum, RPM, and the RHN remote management tool).
To configure the operating environment to support FIPS Approved mode, perform the following steps:
1. Insure that the system is registered with the unbreakable Linux Network (ULN) and that the
OL7_X86_64_latest channel is enabled
# yum-config-manager –enable ol7_latest
2. Install the dracut-fips package:
# yum install dracut-fips
3. Install the dracut-fips-aesni package (if AES-NI is supported):
To check if AES-NI is supported run:
# grep aes /proc/cpuinfo
If it is supported, run:
# yum install dracut-fips-aesni
4. Recreate the INITRAMFS image:
# dracut -f
5. Perform the following steps to configure the boot loader so that the system boots into FIPS mode:
a) Identify the boot partition and the UUID of the partition. If /boot or /boot/efi resides on a separate
partition, the kernel parameter boot=<partition of /boot or /boot/efi> must be supplied. The partition can
be identified with the command:
# df /boot or df /boot/efi
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 233191 30454 190296 14% /boot
# blkid /dev/sda1
/dev/sda1: UUID="6046308a-75fc-418e-b284-72d8bfad34ba" TYPE="xfs"
b) As the root user, edit the /etc/default/grub file as follows:
i. Add the fips=1 option to the boot loader configuration.
GRUB_CMDLINE_LINUX="vconsole.font=latarcyrheb-sun16
rd.lvm.lv=ol/swap rd.lvm.lv=ol/root crashkernel=auto
vconsole.keymap=uk rhgb quiet fips=1"
Oracle Linux 7 OpenSSH Server Cryptographic Module Security Policy
Page 20 of 25
ii. If the contents of /boot reside on a different partition to the root partition, you must use the
boot=UUID=boot_UUID line to the boot loader configuration to specify the device that should be
mounted onto /boot when the kernel loads.
GRUB_CMDLINE_LINUX="vconsole.font=latarcyrheb-sun16
rd.lvm.lv=ol/swap rd.lvm.lv=ol/root crashkernel=auto
vconsole.keymap=uk rhgb quiet
boot=UUID=6046308a-75fc-418e-b284-72d8bfad34ba fips=1"
iii. Save the changes.
This is required for FIPS to perform kernel validation checks, where it verifies the kernel against the
provided HMAC file in the /boot directory.
Note:
On systems that are configured to boot with UEFI, /boot/efi is located on a dedicated partition as
this is formatted specifically to meet UEFI requirements. This does not automatically mean that
/boot is located on a dedicated partition.
Only use the boot= parameter if /boot is located on a dedicated partition. If the parameter is
specified incorrectly or points to a non-existent device, the system may not boot.
If the system is no longer able to boot, you can try to modify the kernel boot options in grub to
specify an alternate device for the boot=UUID=boot_UUID parameter, or remove the parameter
entirely.
6. Rebuild the GRUB configuration as follows:
On BIOS-based systems, run the following command:
# grub2-mkconfig -o /boot/grub2/grub.cfg
On UEFI-based systems, run the following command:
# grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg
To ensure proper operation of the in-module integrity verification, prelinking must be disabled on all system
files. By default, the prelink package is not installed on the system. However, if it is installed, disable prelinking
on all libraries and binaries as follows:
Set PRELINKING=no in the /etc/sysconfig/prelink configuration file.
If the libraries were already prelinked, undo the prelink on all of the system files as follows:
# prelink –u –a
7. Reboot the system
Oracle Linux 7 OpenSSH Server Cryptographic Module Security Policy
Page 21 of 25
8. Verify that FIPS Mode is enabled by running the command:
# cat /proc/sys/crypto/fips_enabled
The response should be “1”
The version of the RPM containing the validated Modules is the version listed in Section 3. The integrity of the
RPM is automatically verified during the installation of the Modules and the Crypto Officer shall not install the
RPM file if the RPM tool indicates an integrity error.
Use care whenever making configuration changes that could potentially prevent access to the
/proc/sys/crypto/fips_enabled flag (fips=1) in the file/proc. If the module does not detect this flag during
initialization, the module is not setup to operate FIPS compatible mode.
All user space modules depend on this file for running in FIPS compatible mode.
10.1.1 OpenSSH Server Configuration
The user must not use DSA keys for performing SSH authentication as OpenSSH only allows DSA keys with 1024 bit
size which are disallowed as per SP800-131A.
The user must not accept DSA host keys potentially offered during the first contact of an SSH server as OpenSSH
only allows DSA keys with 1024 bit size which are disallowed as per SP800- 131A.
When re-generating RSA host keys, the crypto officer should generate RSA keys with a size of 2048 bit or higher
according to [SP800-131A]. The crypto officer should inform the user base to not use RSA keys with key sizes
smaller than 2048 bits.
With operating environment setup as stated in the above section, the following restrictions are applicable.
For the module, the mode of operation is implicitly assumed depending on the services/security functions invoked
as stated in section 3.3 and the successive sections lists the available ciphers from the module. Any use of non-
approved cipher or non-Approved key size will result in the module entering the non-FIPS mode of operation. No
more cipher addition is possible by configuration or command line options.
• SSH protocol version 1 is not allowed
• GSSAPI is not allowed
• Only the following ciphers are allowed:
o aes128-ctr
o aes192-ctr
o aes256-ctr
o aes128-cbc
o aes192-cbc
o aes256-cbc
o 3des-cbc
o rijndael-cbc@lysator.liu.se
Only the following message authentication codes are allowed:
• hmac-sha1
Oracle Linux 7 OpenSSH Server Cryptographic Module Security Policy
Page 22 of 25
• hmac-sha2-256
• hmac-sha2-512
• hmac-sha1- etm@openssh.com
• hmac-sha2-256- etm@openssh.com
• hmac-sha2-512- etm@openssh.com
10.2 User Guidance
Use the 'systemctl start sshd' command to start the OpenSSH server, or configure the server to start using
'systemctl enable/disable'. This module is used by connecting to it with an SSH client. See the documentation of
the client, e.g. the Oracle Linux 7 OpenSSH Client Cryptographic Module's Security Policy and the sshd(1) man
page, for more information.
10.2.1 Handling Self-Test Errors
The OpenSSH self-test consists of the software integrity test. If the integrity test fails, OpenSSH enters an error
state. To recover from the error state, the module must be restarted. If the failure persists, the module must be
reinstalled. The bound OpenSSL module's self tests failures will prevent OpenSSH from operating. See the
Guidance section in the OpenSSL Security Policy for instructions on handling OpenSSL self-test failures.
