16 FIPS Cryptography Federal information processing standard (FIPS) cryptography provides cryptographic algorithms conforming to various FIPS standards published by the National Institute of Standards and Technology (NIST), a non-regulatory agency of the US Department of Commerce. FIPS mode is also validated for numerous platforms to meet the FIPS-140-2 standard for a software-based cryptographic module. This chapter describes how to enable FIPS cryptography requirements on Dell Networking platforms. NOTE: The Dell Networking OS uses an embedded FIPS 140-2-validated cryptography module (Certificate #1747) running on NetBSD 5.1 per FIPS 140-2 Implementation Guidance section G.5 guidelines. NOTE: Only the following features use the embedded FIPS 140-2-validated cryptography module: • SSH Client • SSH Server • RSA Host Key Generation • SCP File Transfers Currently, other features using cryptography do not use the embedded FIPS 140-2-validated cryptography module. Topics: • Configuration Tasks • Preparing the System • Enabling FIPS Mode • Generating Host-Keys • Monitoring FIPS Mode Status • Disabling FIPS Mode Configuration Tasks To enable FIPS cryptography, complete the following configuration tasks. • Preparing the System • Enabling FIPS Mode • Generating Host-Keys • Monitoring FIPS Mode Status • Disabling FIPS Mode Preparing the System Before you enable FIPS mode, Dell Networking recommends making the following changes to your system. 1 Disable the Telnet server (only use secure shell [SSH] to access the system). 2 Disable the FTP server (only use secure copy [SCP] to transfer files to and from the system). 3 Attach a secure, standalone host to the console port for the FIPS configuration to use. 324 FIPS Cryptography
