Title

The Juniper EX switch must be configured to generate audit records when modifying administrator privileges. (Cat II impact)

Discussion

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 network device (e.g., module or policy filter).

Check Content

Determine if the network device generates audit records when modifying administrator privileges. 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 <IPv4 or IPv6 syslog address> { any info; } file <file name> { 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 e.g., "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 <IPv4 or IPv6 syslog address> { change-log info; interactive-commands info; structured-data; } file <file name> { any info; structured-data; } If the network device does not generate audit records when modifying administrator privileges, this is a finding.

Fix Text

Configure the network device to generate audit records when modifying administrator privileges. set system syslog host <IPv4 or IPv6 syslog address> change-log info set system syslog host <IPv4 or IPv6 syslog address> interactive-commands info -or- set system syslog host <IPv4 or IPv6 syslog address> any info set system syslog file <file name> change-log info set system syslog file <file name> interactive-commands info -or- set system syslog file <file name> any info
