Awards and Recognition Comprehensive Log Analysis and Reporting For Fortigate Firewalls Firewall Analyzer fetches logs from Fortigate Firewall, analyzes policies, monitors security events and provides extensive Fortigate log reports it also supports other firewalls. Firewall Analyzer Fortigate log analyzer has an inbuilt syslog server which can receive the Fortigate logs, either in WELF or in syslog format and provides in-depth Fortigate log analysis. You need to configure Fortigate firewalls to send the logs to the Firewall Analyzer syslog server in either of these formats only. Firewall Fortigate syslogs reveal a lot of information on the nature of traffic coming in and going out of the firewall, allows you to plan your bandwidth requirement based on the bandwidth usage across the firewalls Analyzing these firewall traffic logs is vital to understanding network and bandwidth usage and plays an important role in business risk assessment. Firewall Analyzer acts as a Fortigate log viewer and offers many features that help in collecting, analyzing and reporting on firewall logs.

A DLP sensor can also contain archiving options, which these logs are then archived to the log device. The NAC Quarantine option allows the FortiGate unit to record details of DLP operation that involve the ban and quarantine actions, and sends these to the event log file. You can enable logging MAC addresses using the following command syntax: config log setting end When enabled, a new log message is recorded every time a MAC address entry is added to the ARP table, and also when a MAC address is removed as well.
Application control Application control logs provide detailed information about the traffic that internet applications such as Skype are generating. The application control feature controls the flow of traffic from a specific application, and the FortiGate unit examines this traffic for signatures that the application generates. The log messages that are recorded provide information such as the type of application being used such as P2P software , and what type of action the FortiGate unit took.
These log messages can also help you to determine the top ten applications that are being used on your network. This feature is called application control monitoring and you can view the information from a widget on the Executive Summary page. The application control list that is used must have logging enabled within the list, as well as logging enabled within each application entry. Each application entry can also have packet logging enabled. Packet logging for application control records the packet when an application type is identified, similar to IPS packet logging.
Logging of application control activity can only be recorded when an application control list is applied to a firewall policy, regardless of whether or not logging is enabled within the application control list.
Antivirus Antivirus logs are recorded when, during the antivirus scanning process, the FortiGate unit finds a match within the antivirus profile, which includes the presence of a virus or grayware signature. Antivirus logs provide a way to understand what viruses are trying to get in, as well as additional information about the virus itself, without having to go to the FortiGuard Center and do a search for the detected virus.
The link is provided within the log message itself. These logs provide valuable information such as: the name of the detected virus the name of the oversized file or infected file the action the FortiGate unit took, for example, a file was blocked URL link to the FortiGuard Center which gives detailed information about the virus itself The antivirus profile must have log settings enabled within it so that the FortiGate unit can record this activity, as well as having the antivirus profile applied to a firewall policy.
These log messages provide valuable and detailed information about this particular traffic activity on your network. Web filtering activity is important to log because it can inform you about: what types of web sites employees are accessing users attempting to access banned web sites and how often this occurs network congestion due to employees accessing the Internet at the same time web-based threats resulting from users visiting non-business-related web sites Web Filter logs are an effective tool to help you determine if you need to update your web filtering settings within a web filter profile due to unforeseen threats or network congestion.
These logs also inform you about web filtering quotas that have been configured for filtering HTTP traffic.
You must configure logging settings within the web filter profile and apply the filter to a firewall policy so that the FortiGate unit can record the activity.
IPS attack IPS logs, also referred to as attack logs, record attacks that occurred against your network. Attack logs contain detailed information about whether the FortiGate unit protected the network using anomaly-based defense settings or signature-based defense settings, as well as what the attack was.
The IPS or attack log file is especially useful because the log messages that are recorded contain a link to the FortiGuard Center, where you can find more information about the attack. This is similar to antivirus logs, where a link to the FortiGuard Center is provided as well that informs you of the virus that was detected by the FortiGate unit.
An IPS sensor with log settings enabled must be applied to a firewall policy so that the FortiGate unit can record the activity. Packet logs When you enable packet logging within an IPS signature override or filter, the FortiGate unit examines network packets, and if a match is found, saves them to the attack log.
Packet logging is designed to be used as a diagnostic tool that can focus on a narrow scope of diagnostics, rather than a log that informs you of what is occurring on your network. You should use caution when enabling packet logging, especially within IPS filters.
Filter configuration that contains thousands of signatures could potentially cause a flood of saved packets, which would take up a lot of storage space on the log device. It would also take a great deal of time to sort through all the log messages, as well as consume considerable system resources to process.
You can archive packets, but you must enable this option on the Log Settings page. If your log configuration includes multiple FortiAnalyzer units, packet logs are only sent to the primary first FortiAnalyzer unit. Sending packet logs to the other FortiAnalyzer units is not supported. Email filter Email filter logs, also referred to as spam filter logs, record information regarding the content within email messages. For example, within an email filter profile, a match is found that finds the email message to be considered spam.
Email filter logs are recorded when the FortiGate unit finds a match within the email filter profile and logging settings are enabled within the profile. If you are using a Banned Words List for email filtering, note that the filter pattern number is only recorded when the source email address contains a banned word.
Archived logs are usually saved for historical use and can be accessed at any time. IPS packet logs can also be archived, within the Log Settings page. You must enable the archiving to record log archives. Logs are not archived unless enabled, regardless of whether or not the DLP sensor for archiving is applied to the firewall policy. Network scan Network scan logs are recorded when a scheduled scan of the network occurs. A scheduled scan must be configured and logging enabled within the Event Log settings, for the FortiGate unit to record these log messages.
Log messages Log messages are recorded by the FortiGate unit, giving you detailed information about the network activity. Each log message has a unique number that helps identify it, as well as containing fields; these fields, often called log fields, organize the information so that it can be easily extracted for reports. These log fields are organized in such a way that they form two groups: the first group, made up of the log fields that come first, is called the log header.
The log header contains general information, such as the unique log identification and date and time that indicates when the activity was recorded. The log body is the second group, and contains all the other information about the activity. There are no two log message bodies that are alike, however, there may be fields common to most log bodies, such as the srcintf or identidix log fields. The log header also contains information about the log priority level which is indicated in the level field.
The priority level indicates the immediacy and the possible repercussions of the logged action. There are six log priority levels. The log severity level is the level at and above which the FortiGate unit records logs.
The log severity level is defined by you when configuring the logging location. The FortiGate unit will log all messages at and above the priority level you select. For example, if you select Error, the unit will log only Error, Critical, Alert, and Emergency level messages. Log priority levels.
