Cisco IOS XE Switch NDM STIG:
CISC-ND-001410
(in versions v2 r8 through v1 r0.1)
Title
The Cisco switch must be configured to support organizational requirements to conduct backups of the configuration when changes occur. (Cat II impact)
Discussion
System-level information includes default and customized settings and security attributes, including ACLs that relate to the network device configuration, as well as software required for the execution and operation of the device. Information system backup is a critical step in ensuring system integrity and availability. If the system fails and there is no backup of the system-level information, a denial of service condition is possible for all who utilize this critical network component. This control requires the network device to support the organizational central backup process for system-level information associated with the network device. This function may be provided by the network device itself; however, the preferred best practice is a centralized backup rather than each network device performing discrete backups.
Check Content
Review the Cisco switch configuration to verify that it is compliant with this requirement. The example configuration below will send the configuration to a TFTP server when a configuration change occurs. event manager applet BACKUP_CONFIG event syslog pattern "%SYS-5-CONFIG_I" action 1 info type switchname action 2 cli command "enable" action 3 cli command "copy run tftp" pattern "remote host" action 4 cli command "x.x.x.x" pattern "filename" action 5 cli command "$_info_switchname-config" action 6 syslog priority informational msg "Configuration backup was executed" If the Cisco switch is not configured to conduct backups of the configuration when changes occur, this is a finding.
Fix Text
Configure the Cisco switch to send the configuration to a TFTP or FTP server when a configuration change occurs as shown in the example below: SW4(config)#event manager applet BACKUP_CONFIG SW4(config-applet)#event syslog pattern "%SYS-5-CONFIG_I" SW4(config-applet)#action 1 cli command "enable" SW4(config-applet)#action 2 info type switchname SW4(config-applet)#action 3 cli command "copy run tftp" pattern "remote host" SW4(config-applet)#action 4 cli command "x.x.x.x" pattern "filename" SW4(config-applet)#action 5 cli command "$_info_switchname-config" SW4(config-applet)#action 6 syslog priority informational msg "Configuration backup was executed" SW4(config-applet)#end
