Creare Security Alerts in Microsoft 365

In this blog post, we will learn how to create security alerts in Microsoft 365 that will notify us in case a security incident is happening or about to happen.

A few days ago, we learned about the security tools and portals in Microsoft 365, and today we will use the Microsoft 365 Security Center.

Create a Security Alert

Let’s start with creating a security alert in Microsoft 365. To do so open the Security Center using the following URL:

https://security.microsoft.com/homepage

From the security portal left navigation menu click on Policies and Office 365 alerts as shown below.

By default, Microsoft has created a set of policies that are enabled and working out of the box. With the default configuration, an alert will be sent to all the tenant administrators users.

Create a custom alert

To create a new alert, click on New alert policy as shown below and fill in the Name, Severity and Category and click Next.

In the Create alert settings page, use the drop-down box to select the activity, the alert will be based on. Scroll down to see the entire list of available activities.

For example, I will use the activity of Create mail forward / redirect which will send me an alert every time a mail forwarding rule is created to.

To complete the wizard, enter the email address of the person who should receive the alert and click and click finish.
