Vulnerability discussion

This requirement supports non-repudiation of actions taken by an administrator and is required in order to maintain the integrity of the configuration management process. All configuration changes to the network device are logged, and administrators authenticate with two-factor authentication before gaining administrative access. Together, these processes will ensure the administrators can be held accountable for the configuration changes they implement.To meet this requirement, the network device must log administrator access and activity.

Check content

Review the switch configuration and verify that logging is enabled. If logging is not enabled or is not enabled with sufficient detail to fulfill the specifications set forth in the VulDiscussion, this is a finding. To determine if logging is enabled, enter: switch#show logging The output must show logging as enabled, with a logging level of informational or debugging. In order to ensure all user commands are captured, the following statement must be in the running config: aaa accounting commands all default start-stop logging [group radius]

Fix text

Enable logging on the switch with sufficient detail to fulfill the specifications set forth in the VulDiscussion. To configure logging to a remote syslog server at the informational level, enter: switch#config switch(config)#logging host [ip address] switch(config)#logging trap informational Then configure the following AAA aaa accounting commands all default start-stop logging [group radius]
