FIPS Cryptography
This chapter describes how to enable FIPS cryptography requirements on Dell Networking platforms. This
feature 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.
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.
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.
