Description
Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter).

Determine if the network device generates audit records for executed commands. Verify the system logs the facility "any", or minimally "change-log" and "interactive-commands", and the logging level is appropriate. Generally, the "all" (debug) logging level should be avoided because the number of logged messages is significant. [edit system syslog] host { any info; } file { change-log info; interactive-commands info; } Note: If minimally logging only configuration changes, there will be other files receiving the events from the other logging facilities (for example "authorizations" or "firewall"). Syslog outputs in standard format unless the "structured-data" directive is configured. Verify the "structured-data" command for all files and external syslog servers requiring that format. For example: [edit system syslog] host { change-log info; interactive-commands info; structured-data; } file { any info; structured-data; } If the network device does not generate audit records for executed commands, this is a finding.
