The FortiGate firewall must generate traffic log entries containing information to establish when (date and time) the events occurred.

Description
Without establishing when events occurred, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. To compile an accurate risk assessment and provide forensic analysis of network traffic patterns, it is essential for security personnel to know when flow control events occurred (date and time) within the infrastructure. Associating event types with detected events in the network traffic logs provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured network element.

Who does this work

6 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-234136r611408_chk)

Log in to the FortiGate GUI with Super-Admin privilege. 1. Click Log and Report. 2. Click Events, or Local Traffic. 3. Verify events are generated containing date, time, and alert level related to System and Local Traffic Log. In addition to System log settings, verify individual firewall policies are configured with most suitable Logging Options. 1. Click Policy and Objects. 2. Click IPv4 or IPv6 Policy. 3. Verify all Policy rules are configured with Logging Options set to log All Sessions (for most verbose logging). If the log events do not contain information to establish date and time, this is a finding.

Fix Text (F-37286r611407_fix)

This fix can be performed on the FortiGate GUI or on the CLI. Log in to the FortiGate GUI with Super-Admin privilege. 1. Click Log and Report. 2. Click Log Settings. 3. Click All for the Event Logging and Local Traffic Log options (for most verbose logging), or Click Customize and choose granular logging options to meet organization needs. 4. Click Apply. In addition to these log settings, configure individual firewall policies with the most suitable Logging Options. 1. Click Policy and Objects. 2. Click IPv4 or IPv6 Policy. 3. For each policy, configure Logging Options to log All Sessions (for most verbose logging). 4. Confirm each created Policy is Enabled. 5. Click OK. or 1. Open a CLI console. 2. Run the following command: # config log eventfilter # set event enable # set system enable # set endpoint enable # set user enable # set security-rating enable # end # config firewall policy # edit 0 # set srcintf {interface_name_1} # set dstintf {interface_name_2} # set srcaddr {address_a} # set dstaddr {address_b} # set schedule {always} # set service {service required by site policy} # set action {accept} # set logtraffic enable # next # end The {} indicate the object is defined by the organization policy.
