IMPORTANT
SNS 3.x versions have reached End of Maintenance since July 1st, 2024.
We recommend that you update your SNS firewalls to a version with maintenance to guarantee the protection of your infrastructure.

# “Configuration” tab

This tab contains all the necessary parameters for configuring e-mail alerts.

It consists of the following elements:

## Enable e-mail notifications

This option enables the configuration of alerts. If it is disabled, none of the configuration items will be accessible as the firewall will not send ay e-mails. This option is disabled by default.

REMARK

The e-mail notification feature requires a mail server that can receive e-mails from the firewall.

## SMTP server

Server | This field determines the host (SMTP server) to which the firewall will send e-mails, by selecting it from the object database. This field is empty by default.
Port | Port on the SMTP server to which e-mails will be sent. A list allows selecting an object, whose default value will be “SMTP”.
E-mail address | Specifies the e-mail address of the sender and makes it possible to ensure compatibility with external SMTP services such as Microsoft Office 365. The sender's e-mail address suggested by default starts as follows: '<firewall_name>@'.
Authentication | A login and password can now be defined for sending e-mails via the firewall. This checkbox allows you to enable the authentication of the firewalls when sending e-mail alerts.
Identifier | This entry is disabled if the Authentication option has not been selected. This field allows entering the SMTP username (this entry has to be provided if authentication has been enabled).
Password | This entry is disabled if the Authentication option has not been selected. This field allows entering the SMTP username (this entry has to be provided if authentication has been enabled).
Testing the SMTP configuration | This button makes it possible to send a test e-mail to check the firewall's SMTP configuration. After having clicked on Test the SMTP configuration, enter the e-mail address of the recipient for the test e-mail in the window that opens, then click on Send.

## E-mail sending frequency (in minutes)

Sending frequency | This option allows you to specify the frequency with which reports will be sent. A report contains all the alarms detected from the previous report. As such, e-mails will be received during certain time slots and not each time an alarm is raised. The default value is 15.

## Intrusion prevention alarms

Here, you may select a group to notify of intrusion prevention alarms.

The list of alarms will be sent in the body of the e-mail to the specified group.

The frequency for sending alarm reports can be modified in the field “Sending frequency” in the menu E-mail sending frequency (in minutes).

Example

If you define a frequency of 15 minutes in the field Sending frequency, you will be informed by e-mail every 15 minutes of alarms that were raised on the firewall during this period.

Do not send any e-mails | No e-mails regarding alarms will be sent to a specific recipient. This option is selected by default, and used to enable e-mail notifications in order to approve certificate requests, for example, without necessarily generating e-mails for alarms.
Send according to alarm and event settings | Only intrusion prevention and system event alarms for which the Send an e-mail checkbox has been selected will activate the sending of an e-mail.
Send only major alarms | If this option is selected, the group selected in the next field will receive major alarms, which will act as a configured e-mail notification (Applications and Protections module / Advanced column).
Message recipient | Selection of the group that will receive major intrusion prevention alarms.
Send major and minor alarms | If this option is selected, the group selected in the next field will receive major and minor intrusion prevention alarms, which will act as a configured e-mail notification (Applications and Protections module / Advanced column).
Message recipient | Selection of the group that will receive major and minor intrusion prevention alarms.

## System events

Like the previous field, a group can also be notified of system events.

The frequency for sending system events can be modified, likewise, in the field Sending frequency in the menu E-mail sending frequency (in minutes).

Do not send any e-mails | No e-mails regarding system events will be sent to a specific recipient. This option is selected by default, and used to enable e-mail notifications in order to approve certificate requests, for example, without necessarily generating e-mails for system events.
Send only major alarms | If this option is selected, the group selected in the next field will receive major system events, which will act as a configured e-mail notification (Applications and Protections module / Advanced column).
Message recipient | Selection of the group that will receive major system events.
Send major and minor alarms | If this option is selected, the group selected in the next field will receive major and minor system events, which will act as a configured e-mail notification (Applications and Protections module / Advanced column).
Message recipient | Selection of the group that will receive major and minor system events.

REMARK

The status of system events can be viewed in a module of the same name: In the menu, go to Notifications>System events.
