Alert emails are used to notify administrators about events on the FortiGate device, allowing a quick response to any issues.
There are two methods that can be used to configure email alerts:
The FortiGate has a default SMTP server, notification.fortinet.net, that provides secure mail service with SMTPS. It is used for all emails that are sent by the FortiGate, including alert emails, automation stitch emails, and FortiToken Mobile activations. You can also configure a custom email service.
To configure a custom email service in the GUI:
Go to System > Settings.
In the Email Service section, enable Use custom settings.
Configure the following settings:
Enter the address or name of the SMTP server, such as smtp.example.com.
If required, select Specify and enter a specific port number. The default is port 465.
If required by the email server, enable authentication.
If enabled, enter the Username and Password.
Set the security mode: None, SMTPS, or STARTTLS.
Default Reply To
Optionally, enter the reply to email address, such as email@example.com.
This address will override the from address that is configured for an alert email.
To configure a custom email service in the CLI:
config system email-server set reply-to "firstname.lastname@example.org" set server "smtp.fortinet.net" set port 465 set authenticate enable set username "fortigate" set password ********** set security smtps end
Automation stitches can be configured to send emails based on a variety of triggers, giving you control over the events that cause an alert, and who gets alerted. For more information, see Automation stitches.
In this example, the default mail service sends an email to two recipients when there is a configuration change or an Admin login failed event occurs.
To configure the automation stitch in the GUI:
On the root FortiGate, go to Security Fabric > Automation and click Create New.
Enter a name for the stitch, such as Admin Fail.
In the Trigger section, select FortiOS Event Log.
Click in the Event field, and in the slide out pane, search for and select Admin login failed.
In the Action section, select Email.
Configure the Email settings:
In the To field, click the plus icon, then enter the two email recipients' addresses, such as email@example.com and firstname.lastname@example.org.
Enter the Email subject, such as Admin log in failed.
Edit the Email body as required. By default, the email body will include all the fields from the log event that triggered the stitch.
Create a second stitch, selecting Configuration Change as the trigger.
To configure the automation stitch in the CLI:
Create automation actions to send the email messages:
config system automation-action edit "Config Change_email" set action-type email set email-to "email@example.com" "firstname.lastname@example.org" set email-subject "Configuration Change Detected" next edit "Admin Fail_email" set action-type email set email-to "email@example.com" "firstname.lastname@example.org" set email-subject "Admin log in failed" next end
- Create the automation triggers:
config system automation-trigger edit "Config Change" set event-type config-change next edit "Admin Fail" set event-type event-log set logid 32002 next end
Create the automation stitches:
config system automation-stitch edit "Config Change" set trigger "Config Change" set action "Config Change_email" next edit "Admin Fail" set trigger "Admin Fail" set action "Admin Fail_email" next end
When configuring an alert email, you can define the threshold when an issue becomes critical and requires attention. When the threshold is reached, an email is sent to up to three recipients on the configured schedule to notify them of the issue.
In this example, the FortiGate is configured to send email messages to two addresses, email@example.com and firstname.lastname@example.org, every two minutes when multiple intrusions, administrator log in or out events, or configuration changes occur.
To configure an alert email in the GUI:
Go to Log & Report > Email Alert Settings and enable Enabled.
Configure the following:
Enter the name in the From field of the message: email@example.com.
Enter the two addresses that the message is sent to: firstname.lastname@example.org and email@example.com
Send the alert based on specific events (
category), as opposed to the severity (
Set the interval between messages to 2 minutes.
Enable Intrusion detected (
Enable Administrator login/logout (
admin-login-logs) and Configuration change (
To configure an alert email in the CLI:
config alertemail setting set username firstname.lastname@example.org set mailto1 email@example.com set mailto2 firstname.lastname@example.org set filter-mode category set email-interval 2 set IPS-logs enable set configuration-changes-logs enable set admin-login-logs enable end
