The Dell OS10 Switch must be configured to implement cryptographic mechanisms using a FIPS 140-2 approved algorithm to protect the confidentiality of remote maintenance sessions.

Severity	Group ID	Group Title	Version	Rule ID	Date	STIG Version
high	V-269797	SRG-APP-000412-NDM-000331	OS10-NDM-000790	SV-269797r1052421_rule	2024-12-11	1

Description
This requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP. If unsecured protocols (lacking cryptographic mechanisms) are used for sessions, the contents of those sessions will be susceptible to eavesdropping, potentially putting sensitive data (including administrator passwords) at risk of compromise, and potentially allowing hijacking of maintenance sessions.

ℹ️ Check
Review the OS10 Switch configuration to determine if cryptographic mechanisms are implemented using a FIPS 140-2 approved algorithm to protect the confidentiality of remote maintenance sessions. 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# Verify that SSH is enabled for network access by reviewing the SSH server status: OS10# show ip ssh \| grep "SSH Server:" SSH Server: Enabled Verify that telnet is disabled on the switch by verifying that the following is not in the running-configuration: ip telnet server enable If FIPS mode is not enabled, if the SSH is not enabled, or if telnet is enabled in the OS10 Switch, this is a finding.

✔️ Fix
Configure the OS10 Switch to implement cryptographic mechanisms to protect the confidentiality of remote maintenance sessions using a FIPS 140-2 approved algorithm: 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)# Disable telnet if it has been enabled: OS10(config)# no ip telnet server enable Enable SSH if it has been disabled: OS10(config)# ip ssh server enable
