The Juniper EX switch must be configured to generate audit records containing the full-text recording of privileged commands.

Description
Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information. Organizations consider limiting the additional audit information to only that information explicitly needed for specific audit requirements. The additional information required is dependent on the type of information (i.e., sensitivity of the data and the environment within which it resides). At a minimum, the organization must audit full-text recording of privileged commands. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise.

Check Text ( C-57347r843716_chk )
Determine if the network device generates audit records containing the full-text recording of privileged 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 such audit records are not being generated, this is a finding.
