The Juniper SRX Services Gateway must generate log records containing the full-text recording of privileged commands.
Vulnerability discussion
Reconstruction of harmful events or forensic analysis is not possible if log records do not contain enough information. Organizations consider limiting the additional audit information to only that information explicitly needed for specific audit requirements. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise. While the Juniper SRX inherently has the capability to generate log records, by default only the high facility levels are captured and only to local files. Ensure at least one Syslog server and local files are configured to support requirements. However, the Syslog itself must also be configured to filter event records so it is not overwhelmed. A best practice when configuring the external Syslog server is to add similar log-prefixes to the log file names to help and researching of central Syslog server. Another best practice is to add a match condition to limit the recorded events to those containing the regular expression (REGEX).
Check content
Verify logging has been enabled and configured.
[edit]
show system syslog
If at least one valid syslog host server and the syslog file names are not configured to capture "any" facility and "any" event, this is a finding.
Fix text
The following commands configure syslog to record any use of any command, including privileged commands. Configure Syslog and local backup files to capture DoD-defined auditable events.

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.
