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 router configuration to determine if it logs configuration changes as shown in the following example: system { syslog { file LOG_FILE { change-log info; } } } Note: The parameter “any” can be in place of “change-log” as this will log everything. Also, a syslog server can be configured in addition to or in lieu of logging to a file as shown in the example below. system { syslog { host 10.1.58.2 { any info; } file LOG_FILE { change-log info; } console { any error; } } } If configuration change activity is not logged, this is a finding.

Fix text

Configure the router to log configuration changes as shown in the following example: set syslog file LOG_FILE change-log info Note: The parameter “any” can be in place of “change-log” as this will log everything. Also, a syslog server can be configured in addition to or in lieu of logging to a file as shown in the example below. set syslog host 10.1.58.2 any info

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
