JUNI-RT-000200 - The Juniper router must be configured to log all packets that have been dropped - syslog

Information

Auditing and logging are key components of any security architecture. It is essential for security personnel to know what is being done or attempted to be done, and by whom, to compile an accurate risk assessment. Auditing the actions on network devices provides a means to recreate an attack or identify a configuration mistake on the device.

Solution

Configure the firewall terms that discards or rejects packets to log the action as shown in the example below.

[edit firewall family inet]
set filter FILTER_INBOUND term DENY_BY_DEFAULT then syslog discard

Configure logging to record packets being dropped by firewall filters as shown in the example below.

[edit system syslog]
set file LOG_FILE firewall any

Note: The 'any' parameter can be configured in lieu of the 'firewall' parameter.
