Introduction

In this article, we will explore the process of configuring notification forwarding in Cortex XDR. Notification forwarding allows users to receive alerts through various communication channels such as email, Slack, and syslog. We will discuss the prerequisites for receiving these notifications and provide a step-by-step guide on how to configure them. Additionally, we will cover the integration of Slack and syslog, along with examples of different types of notifications. So let's dive in and learn how to effectively set up and manage notification forwarding in Cortex XDR.

Prerequisites for Receiving Notifications

Before configuring notification forwarding, there are a few prerequisites to consider. For email notifications, all You need is a valid email address. To integrate with Slack, you must have a Slack workspace and Channel, and enable it in the settings configurations. For syslog notifications, you need to have a syslog server enabled at the same location. Keep in mind that access must be enabled from certain Cortex XDR IP addresses in your firewall settings. These addresses can be found in the documentation.

Configuring Notification Forwarding

To configure notification forwarding, navigate to the settings configurations and select notifications. Here, you can view pre-existing notification configurations and their details. You can also edit, disable, or delete existing configurations. Clicking on the add forwarding configuration button allows you to Create a new notification configuration. Provide a name, description, and select the log Type (alerts, agent audit logs, or management audit logs).

Next, you can set filters for specific alerts and select the communication channels for forwarding notifications. You can add email, Slack, and syslog server to the configuration. The grouping time frame allows you to control the frequency of email notifications. You can choose to aggregate alerts within a specific timeframe or receive notifications for each alert generated.

Adding a New Notification Configuration

To add a new notification configuration, navigate to the settings configurations and select notifications. Click on the add forwarding configuration button. Provide a name, description, and select the log type. Next, set filters for specific alerts and select the communication channels for forwarding notifications. You can add email, Slack, and syslog server to the configuration. Adjust the grouping time frame according to your preferences. Once you have configured all the settings, click on create to save the configuration.

Viewing and Managing Notification Configurations

To view and manage notification configurations, go to the settings configurations and select notifications. Here, you can see all the pre-existing notification configurations along with their details. You can edit, disable, or delete these configurations. The right-click menu provides easy access to these options. You can also view the log format for every type of alert or event log. This log format view is available for each notification forwarder.

Establishing Slack Integration

To integrate Slack with Cortex XDR, go to the settings configurations, select integrations, and choose external applications. Here, you can see the Slack application and the workspace it is connected to. To set up the integration, select the workspace and allow access when prompted. After syncing the channels, search for your desired Slack channel and add it to the list. Save the configuration, and you are all set to receive notifications in Slack.

Testing Slack Integration

To test the Slack integration, go to the Slack workspace and channel that you added in the previous step. Cortex XDR automatically sends a test notification to the channel. You will receive the notification with details such as severity, source, category, and action description. You can click on the notification to view more information and investigate the incident further.

Setting Up Syslog Receiver

To set up a syslog receiver, go to the settings configurations and select integrations, then external applications. Here, you can view and manage existing syslog servers. To add a new syslog server, click on the new server button. Provide the necessary details like name, address, port, certificate name, and protocol. You can also upload a certificate for TLS communication. Test the syslog server if required, and save the configuration.

Validating Syslog Servers

To validate syslog servers, go to the syslog server list in the settings configurations. Here, you can view the attributes of each server, such as name, address, port, and status. You can edit, delete, or send a test message to the servers through the right-click menu. Any log forwarded to the syslog server will be sent in CEF format, divided into syslog header, CEF header, and CEF body sections.

Email Notification Forwarding

Email notification forwarding is the simplest method as it does not require any integration. You can add any valid email address to the distribution list. The grouping time frame option allows you to control the frequency of email notifications. You can choose to aggregate alerts within a specific time frame or receive notifications for each alert generated.
