Vulnerability discussion

Without generating log records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. While the Juniper SRX inherently has the capability to generate log records, by default only the high facility levels are captured by default 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 a 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 example commands configure Syslog and local backup files to capture DoD-defined auditable events. [edit] set system syslog user * any emergency set system syslog host any any set system syslog host source-address set system syslog host log-prefix set system syslog file messages any info set system syslog file messages authorization none set system syslog file messages interactive-commands none set system syslog file messages daemon none set system syslog file User-Auth authorization any set system syslog file interactive-commands interactive-commands any set system syslog file processes daemon any set system syslog file account-actions change-log any any set file account-actions match “system login user” set system syslog console any any

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.
