You should log as much information as possible when you first configure FortiOS. Michael Pruett, CISSP has a wide range of cyber-security and network engineering expertise. Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. Logging records the traffic passing through the FortiGate unit to your network and what action the FortiGate unit took during its scanning process of the traffic. 2. The event log records administration management as well as Fortinet device system activity, such as when a configuration has changed, admin login, or high availability (HA) events occur. Anthony_E. When available, the logs are the most accessible way to check why traffic is blocked. Scope, Define, and Maintain Regulatory Demands Online in Minutes. 1. How to check the logs. enable. Use the following CLI command to see what log forwarding IDs have been used: The following line will be displayed to confirm the creation of the log aggregation: check for cfg[] svr_disp_name=. Associating information about where the event occurred within the network provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured network element. FortiGate, FortiCarrier, FortiMail, FortiWeb, and FortiClient logging is supported. This option is only available when the remove server is a Syslog or CEF server. In order to compile an accurate risk assessment and provide forensic analysis, security personnel need to know the source of the event. Created on Then, add Log Fields to the Exclusion List by clicking Fields and specifying the excluded log fields in the Select Log Field pane. Verify traffic log events contain source and destination IP addresses, and interfaces. This recorded information is called a log message. No configuration is required on the server side. Edited By Adding traffic shapers to multicast policies . 4. Click Select Device, then select the devices whose logs will be forwarded. Description. Local traffic is traffic that originates or terminates on the FortiGate itself - when it initiates connections to DNS servers, contacts FortiGuard, administrative access, VPNs, communication with authentication servers and similar.

FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic. This fix can be performed on the FortiGate GUI or on the CLI. Debug log may also be required.When opening a TAC support case, attach them and in more complex scenarios, the traffic path is needed as well:(ie: PC >> port1 (vlan 100, vdom TEST, policy 17) >> zone PROD >> vdom link TEST_to_PROD >> port9 (vlan 15, policy 413) >> internet port wa1 )Traffic logs (logging must be enabled in policy) or Security logs (AV/Webfilter/IPS/etc. Fill in the information as per the below table, then click OK to create the new log forwarding. If it is needed to revert to a working version, make sure to collect all the logs or call us, otherwise the support cant investigate or provide a possible cause.To downgrade quickly to a previous firmware (the previous firmware version is kept in memory).- Policy / inspection profiles changes: review the last change. option- Option. . Settings for this are available via CLI (disabled by default): Enable implicit firewall policy logging. Go to System Settings > Log Forwarding. Export a small group of such logs from the logging unit (FortiGate GUI, FortiAnalyzer, FortiCloud, Syslog, etc).Packet capture (sniffer): On models with hardware acceleration, this has to be disabled temporarily in order to capture the traffic.It is better captured from command line and log the SSH output.Debug flow (firewall logic): Common cases where traffic is not passing, and shown in debug flow for new sessions:'Denied by forward policy check'. Check the ID number of this policy.- Make sure that the session from source to destination is matching this policy:(check 'policy_id=' in the output). 04-07-2021 option-resolve-port: Enable/disable adding resolved service names to traffic logs. Sometimes also the reason why. 3. Enable/disable inserting policy comments into traffic logs.

Forward traffic logs concern any incoming or outgoing traffic that passes through the FortiGate, like users accessing resources in another network.Local traffic is traffic that originates or terminates on the FortiGate itself when it initiates connections to DNS servers, contacts FortiGuard, administrative access, VPNs, communication with authentication servers and similar.This traffic also generates log messages. Logging and reporting go hand in hand, and can become a valuable tool for information as well as helping to show others the activity that is happening on the network. Attach relevant logs of the traffic in question. Forwarding mode only requires configuration on the client side. FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.

If you need to, increase the level of logging (such as from Warning to Information) to obtain more information. Log in to the FortiGate GUI with Super-Admin privilege. Default: 514. Enable/disable adding resolved service names to traffic logs. This traffic also generates log messages. Technical Tip: Displaying logs via FortiGate's CLI. Enable/disable adding resolved domain names to traffic logs if possible. Determine the activities that generate the most log entries: Logs can help identify and locate any problems, but they do not solve them. This log is needed when creating a TAC support case.- Start with the policy that is expected to allow the traffic. If you are forwarding logs to a Syslog or CEF server, ensure this option is supported before turning it on. .. are the same as in FortiOS 6.2 (listed bellow), but adds following new categories: .. are the same as in FortiOS 6.2 (listed bellow), but adds following new category: The default log filter configuration looks like below. This fix can be performed on the FortiGate GUI or on the CLI. 'Find an existing session, id-0xxxxxxxx, reply direction': a session is already established and the traffic is flowing (possibly Layer7 problem - packet capture needed).Debug log (snapshot of the system parameters at the time it is downloaded):If Authentication and user groups are used in policies, check also this guide related articles below.For SIP/VoIP issues, a packet capture (usually with 'port 5060' as filter) is absolutely necessary, along with the configuration (backup from GUI of 'Global' context). Local traffic is allowed or denied instead based on interface configuration (Administrative Access), VPN and VIP configuration, explicitly defined local traffic policies and similar configuration items.This means local traffic does not have an associated policy ID unless user-defined local policies have been configured.If there is no user-defined local policy applying to the logged traffic, logs will instead show policy ID 0.In this case, policy ID 0 is NOT the same as implicit deny.Example local traffic log (for incoming RIP message): The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges..
