The Juniper EX switch must be configured to audit the execution of privileged functions.

Description
Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised information system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Auditing the use of privileged functions is one way to detect such misuse and identify the risk from insider threats and the advanced persistent threat.

Determine if the network device audits the execution of privileged functions. This requirement may be verified by demonstration, configuration review, or validated test results. 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 audit the execution of privileged functions, this is a finding.
