Settings changed by enabling FIPS mode
After you enable FIPS mode and restart the device, the following changes occur.
• The FTP/TFTP server is disabled.
• The Telnet server is disabled.
• The HTTP server is disabled.
• SNMP v1 and SNMP v2c are disabled. Only SNMP v3 is available.
• The SSL server only supports TLS1.0.
• The SSH server does not support SSHv1 clients
• The SSH only supports RSA.
• RSA key pairs must have a modulus length of 2048 bits, and DSA key pairs must have a modulus
length from 1024 to 2048 bits.
• SSH, SNMPv3, IPsec and SSL do not support DES, RC4, 3DES, or MD5.
FIPS self-tests
When the device enters FIPS mode, power-up self-tests and conditional self-tests automatically run to
ensure the correct operation of cryptography modules. If either type of tests fails, the device will restart.
Power-up self-tests
Power-up self-tests, also called “known-answer tests”, check the availability of FIPS-allowed cryptographic
algorithms. A cryptographic algorithm runs on data for which the correct output is already known. The
calculated output is compared with the known answer. If they are not identical, the known-answer test
fails.
Power-up self-tests include the following types.
