FortiSIEM Analytics

Analytics

FortiSIEM Analytics has three components:

Search

FortiSIEM search functionality includes real time and and historical search of information that has been collected from your IT infrastructure. With real time search, you can see events as they happen, while historical search is based on information stored in the event database. Both types of search include simple keyword searching, and structured searches that let you search based on specific event attributes and values, and then group the results by attributes.

Rules

Because FortiSIEM is continuously monitoring your IT infrastructure, you can also set rules so that when specific conditions are met, it triggers an incident, and, in some cases, sends a notification.

Reports

Reports are pre-defined search queries. FortiSIEM includes a large catalog of reports for common devices and IT analysis tasks that you can use and customize, and you can also save searches that you’ve run as reports to use again later.

Search

Historical and Real Time search is the core functionality of FortiSIEM analytics, enabling you to analyze, report on, and further improve your IT infrastructure.

Historical Search

With the Historical Search feature, you can go back in time and retrieve events from the event database. By using either a simple keyword-based search or a more detailed structured search, you can get quick and valuable insights into events that have occurred over any selected time period.

Overview of the Historical Search User Interface

You can run two types of historical searches on FortiSIEM data: simple searches, in which you use a keyword search, and structured searches, in which you can specify search conditions and how the results should be grouped.

Simple Historical Search User Interface Controls Structured Historical Search

Simple Historical Search

When you use simple historical search, you enter a keyword to search for in the logs collected by FortiSIEM, specify any filter criteria, and then run the search, which will produce a chart and a list of results matching your search criteria. You can then use additional user interface controls to change the chart display, filter or find more information about events in the result list, and export or share results.

This screenshot shows the results of simple search using the keyword TCP.

Simple Historical Search User Interface Controls

UI Control Description
Search

Criteria

For simple historical search, use the search box to find keywords in raw event logs. You can also load an existing historical search report to use for your search criteria, or create a rule from your search results.
List Display

Columns

Select which columns will be displayed in the search results
Filters Set the time interval over which you want to search, and, for multi-tenant deployments, which organization’s logs you want to search
Report

Management

Save

Saves the report to Generated Reports where it will be retained for the time period you specify. You can also select whether you want the search criteria to be saved as a report that you can use in the future.

Export

Export the report, with the option of including the chart, as a PDF or CSV file Email

Email the report as a CSV or PDF file, with the option of including the chart

Chart Displa y You can set both the data you want to display, and how it should be displayed. See Overview of Historical Search Results and Charts for more about the different chart types.
Event Filter Select an event from the results, and add its attributes to structured search conditions.
Event

Information

Select an event, and view Quick Info about it, or view Location information about it such as source or destination IPs.

Structured Historical Search

With historical structured search, you can enter conditions for your search based on event attributes, and set which attributes will be used to group the search results in a way that is similar to the use of the of the Group By command in SQL

This screenshot shows a structured historical search for All Non-Reporting Modules selected from the system Reports > Event Status. The screenshot below it shows a close-up of the the Conditions and Group By options dialog. See Creating a Structured Historical Search and Struc tured Search Operators for more information about these options.

Example of How a Structured Historical Search is Processed

When you run a structured historical search, all events within the specified time window are examined and added to the result set following these steps:

  1. The system fetches the next event within the search time window and applies the filtering criteria. If the event does not pass the filtering criteria, the system fetches the next event.
  2. If the event passes the filtering criteria, the system then compares the attributes of this event against the other entries in the result set. If the current event contains an attribute that is included in the Group By attribute set, then the results for that attribute are updated. Otherwise, a new entry is created in the result set.
  3. After all the events in the search time window are processed, the system sorts the results to produce the final result set.

As an example, consider these events in the event database, and running a search for Top Firewall Recorded Conversations Ranked By Total Connections (Descending) and Total Bytes (descending) over them.
