Step-by-Step Configuration Procedure

Instructions on the 3rd Party Solution

This setup guide will show you how to forward your FortiMail logs to Sekoia.io by means of a syslog transport channel.

FortiMail Logs

  • On FortiMail appliances, most of the important hardware and software activities that are relevant for security detection and analysis are logged into six files:
    • History (statistics): Records all email traffic going through the FortiMail unit.
    • System Event (kevent): Records system management activities, including changes to the system configuration as well as administrator and user log-ins and log-outs.
    • Mail Event (event): Records mail activities.
    • Antispam (spam): Records spam detection events.
    • Antivirus (virus): Records virus intrusion events.
    • Encryption (encrypt): Records detection of IBE-related events.

Transport to the Collector

  • Prerequisites:

    • Administrator privileges on the FortiMail appliance
    • Traffic towards the syslog must be open on UDP 514

  • Configure Logging to a Syslog Server:

    1. Go to Log and Report > Log Settings > Remote.
    2. Click New to create a new entry OR double-click an existing entry to modify it.
    3. Select Enable to allow logging to a remote host.
    4. In Profile name, enter a profile name.
    5. In IP, enter the IP address of the Syslog server where the FortiMail unit will store the logs.
    6. In Port, enter the UDP port number on which the Syslog server listens for connections (by default, UDP 514).
    7. From Level, select the severity level that a log message must equal or exceed in order to be recorded to this storage location.

    8. From Facility, select the facility identifier that the FortiMail unit will use to identify itself when sending log messages.

      To easily identify log messages from the FortiMail unit when they are stored on a remote logging server, enter a unique facility identifier, and verify that no other network devices use the same facility identifier.

    9. From Log protocol, select Syslog.

    10. In Logging Policy Configuration, enable the types of logs you want to record to this storage location.
    11. Click Create.

Instruction on Sekoia

Configure Your Intake

This section will guide you through creating the intake object in Sekoia, which provides a unique identifier called the "Intake key." The Intake key is essential for later configuration, as it references the Community, Entity, and Parser (Intake Format) used when receiving raw events on Sekoia.

  1. Go to the Sekoia Intake page.
  2. Click on the + New Intake button at the top right of the page.
  3. Search for your Intake by the product name in the search bar.
  4. Give it a Name and associate it with an Entity (and a Community if using multi-tenant mode).
  5. Click on Create.
  6. You will be redirected to the Intake listing page, where you will find a new line with the name you gave to the Intake.

Note

For more details on how to use the Intake page and to find the Intake key you just created, refer to this documentation.

Configure a forwarder

To forward events using syslog to Sekoia.io, you need to update the syslog header with the intake key you previously created. Here is an example of your message before the forwarder 

<%pri%>1 %timestamp:::date-rfc3339% %hostname% %app-name% %procid% LOG RAW_MESSAGE
and after 
<%pri%>1 %timestamp:::date-rfc3339% %hostname% %app-name% %procid% LOG [SEKOIA@53288 intake_key=\"YOUR_INTAKE_KEY\"] RAW_MESSAGE

To achieve this you can:

  • Use the Sekoia.io forwarder which is the official supported way to collect data using the syslog protocol in Sekoia.io. In charge of centralizing data coming from many equipments/sources and forwarding them to Sekoia.io with the apporpriated format, it is a prepackaged option. You only have to provide your intake key as parameter.
  • Use your own Syslog service instance. Maybe you already have an intance of one of these components on your side and want to reuse it in order to centralize data before forwarding them to Sekoia.io. When using this mode, you have to configure and maintain your component in order to respect the expected Sekoia.io format.

Warning

Only the Sekoia.io forwarder is officially supported. Other options are documented for reference purposes but do not have official support.

Raw Events Samples

In this section, you will find examples of raw logs as generated natively by the source. These examples are provided to help integrators understand the data format before ingestion into Sekoia.io. It is crucial for setting up the correct parsing stages and ensuring that all relevant information is captured.

Detection section

The following section provides information for those who wish to learn more about the detection capabilities enabled by collecting this intake. It includes details about the built-in rule catalog, event categories, and ECS fields extracted from raw events. This is essential for users aiming to create custom detection rules, perform hunting activities, or pivot in the events page.

The following Sekoia.io built-in rules match the intake Fortinet FortiMail. This documentation is updated automatically and is based solely on the fields used by the intake which are checked against our rules. This means that some rules will be listed but might not be relevant with the intake.

CVE-2020-0688 Microsoft Exchange Server Exploit

Detects the exploitation of CVE-2020-0688. The POC exploit a .NET serialization vulnerability in the Exchange Control Panel (ECP) web page. The vulnerability is due to Microsoft Exchange Server not randomizing the keys on a per-installation basis resulting in them using the same validationKey and decryptionKey values. With knowledge of these, values an attacker can craft a special viewstate to use an OS command to be executed by NT_AUTHORITY\SYSTEM using .NET deserialization. To exploit this vulnerability, an attacker needs to leverage the credentials of an account it had already compromised to authenticate to OWA.

  • Effort: advanced
Suspicious TOR Gateway

Detects suspicious TOR gateways. Gateways are often used by the victim to pay and decrypt the encrypted files without installing TOR. Tor intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult. Before a network packet starts its journey, user’s computer chooses a random list of relays and repeatedly encrypts the data in multiple layers, like an onion. Each relay knows only enough to strip off the outermost layer of encryption, before passing what’s left on to the next relay in the list.

TOR intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult.
