FIPS Self-Tests Overview

The cryptographic module enforces security rules to ensure that the Juniper Networks Junos operating system (Junos OS) in FIPS mode 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

  • macsec_kats—KAT for MACsec cryptographic implementation

  • md_kats—KAT for libmd and libc

  • openssl_kats—KAT for OpenSSL cryptographic implementation

Note:

For MACsec qualifications, the LC KATs has to perform on AES-GCM-128 and AES-GCM-256.

The device automatically performs the KAT self-tests at startup. The device also performs the conditional self-tests automatically to verify digitally signed software packages, generated random numbers, RSA and ECDSA key pairs, and manually entered keys.

When the device successfully completes the KATs, it updates the log (syslog) file to display the executed tests.

During bootup entropy health test is performed. The system software integrity check is done during bootup. Each software module is verified before being loaded. The messages pertaining to the entropy health check and software integrity checks can be viewed on the console during system bootup.

If one of the self-tests fail, the device panics and reboot continuously. You can recover the device using USB install.

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

Note:

The module implements cryptographic libraries and algorithms that are not utilized in the approved mode of operation.
