You must have the Shifts schedule setup in Microsoft Teams. This blog will walk you through using System Managed Identity for the above connectors.

If you're an owner of multiple teams, you can toggle between different Shifts schedules to manage them. Here is an example of how a Shifts schedule looks like. The schedules will not be visible to your team members until you publish it by clicking “ Share with team” button. In terms of permission, you need to be an Owner of the team to create the schedule. You can either create a schedule from scratch (create for yourself or on behalf of your team members) or import an existing one from Excel. The first step to get started in Shifts is to populate schedules for your team. You can add Shifts app to your Teams menu by clicking on the ellipses (…) and select Shifts from the app list. Shifts is enabled by default for all Teams users in your organization. ![]() Shifts is a schedule management application in Microsoft Teams that helps you create, update, and manage schedules for your team. In this Playbook, an email will be sent to the assignee and a comment will be added to the incident on the incident assignment.It is important to notify the assignee when an incident is being assigned.For example, if a security analyst is about to go off shift in 30 minutes, the incident won’t be assigned to that analyst as the remaining time is less than the default value of 1 hour. In this Playbook, I have set a default value of 1 hour as the MTTR (a configurable variable) and I am using it as a condition where a security analyst must have at least 1 hour remaining in the shift to be eligible for incident assignment. We also need to consider the average time a security analyst takes to resolve a security incident (also known as Mean Time To Resolve - MTTR).Hence, the analyst with the least number of incidents in current shift will be assigned first. The goal is to assign the incidents equally across all analysts.It is easier to automate incident assignment when there is a centralized schedule management tool to keep track of employees’ timesheet or availability.Shifts for Teams is used as the scheduling tool because it is available as part of the Microsoft Teams and it provides the ability to create and manage employee schedules.Plus, I will also discuss how you could manage incident assignments for multiple support groups at the end of the blog.īefore we dive into the Playbook, let’s discuss some of the important points taken into consideration and the design decisions when implementing this incident assignment Playbook. In this blog, I will discuss how to extend the incident assignment capability in Microsoft Sentinel by using a Playbook to rotate user assignments based on shift schedules. However, some organizations have a group of analysts working on different shift schedules and required the ability to assign an incident to an analyst automatically based on the working schedule to improve the MTTA. It will reduce the time of acknowledgement and ensure accountability for each incident. This is extremely useful when you need to assign specific incidents to a dedicated SME. The newly introduced Automation Rules allow you to automatically assign incidents to an owner with the built-in action. ![]() The responsiveness of a security analyst towards the triggered incidents (also known as Mean Time To Acknowledge - MTTA) is crucial as being able to respond to a security incident quickly and efficiently will reduce the incident impact and mitigate the security threats. Microsoft Sentinel Incidents contain detection details which enable security analysts to investigate using a graph view and gain deep insights into related entities.
