FIPS Self-Tests Overview

The cryptographic module enforces security rules to ensure that a device running the Juniper Networks Junos operating system (Junos OS) in FIPS mode of operation meets the security requirements of FIPS 140-3 Level 1. To validate the output of cryptographic algorithms approved for FIPS and test the integrity of some system modules, the device performs the following series of known answer test (KAT) self-tests:

kernel_kats—KAT for kernel cryptographic routines
md_kats—KAT for libmd and libc
openssl_kats—KAT for OpenSSL cryptographic implementation
openssl-102_kats—KAT for OpenSSL-102 cryptographic implementation

The KAT self-tests are performed automatically at startup and reboot, when FIPS mode of operation is enabled on the device. Conditional self-tests are also performed automatically to verify digitally signed software packages, generated random numbers, RSA and ECDSA key pairs, and manually entered keys.

If the KATs are completed successfully, the system log (syslog) file is updated to display the tests that were executed.

If one of the KATs fail, the device panics and reboot continuously. The device can be recovered using USB install.

The file show /var/log/messages command displays the system log.

Performing Power-On Self-Tests on the Device

Each time the cryptographic module is powered on, the module tests that the cryptographic algorithms still operate correctly and that sensitive data has not been damaged.

The module displays the following status output while running the power-on self-tests:
