Fix Recommendation

Configure the OS10 Switch to authenticate SNMP messages using a FIPS-validated Keyed-HMAC.

Ensure FIPS mode is enabled.
OS10(config)# crypto fips enable

WARNING: Upon committing this configuration, the system will regenerate SSH keys. Please consult documentation and toggle FIPS mode only if you know what you are doing!
Continue? [yes/no(default)]:yes
OS10(config)#

Configure an SNMP user to enforce SHA authentication.
OS10(config)# snmp-server group Group3 3 priv notify NOTIFY
OS10(config)# snmp-server user User3 Group3 3 auth sha ********** priv aes **********

Configure the SNMP server to use version 3 and enforce SHA authentication (auth) or both SHA authentication and AES encryption (priv).
OS10(config)# snmp-server host 10.10.10.10 version 3 priv User3 snmp

Check Contents

Review the OS10 Switch configuration to verify SNMP messages are authenticated using a FIPS-validated Keyed-HMAC.

Step 1: Review the FIPS status to verify that FIPS mode is enabled, as shown below:

OS10# show fips status

FIPS mode: Enabled
Crypto Library: OpenSSL 1.0.2zg-fips 7 Feb 2023
FIPS Object Module: DELL OpenSSL FIPS Crypto Module v2.6 July 2021
OS10#

Step 2: Review the SNMP configuration to verify that the server is configured to enforce authentication ({auth|priv} {name}). Verify the SNMP user is configured for SHA authentication (auth sha):

OS10(config)# show running-configuration snmp
!
...
snmp-server group Group3 3 priv notify NOTIFY
snmp-server host 10.10.10.10 traps version 3 priv User3
snmp-server user User3 Group3 3 encrypted auth sha **** priv aes ****

If SNMP is not configured to enforce authentication or FIPS mode is not enabled, this is a finding.
