Εισαγωγή

Welcome to CloudBlogger, a Web Site that gets you ahead in the exciting fields of Azure, DevOps and M365 with detailed Workshops and amazing posts. Today we are implementing Microsoft Copilot for Security the latest Cybersecurity innovation from Microsoft. Copilot for Security is a generative AI security product that empowers security and IT professionals respond to cyber threats, process signals, and assess risk exposure at the speed and scale of AI.

Let’s see what are the prerequisites as the documentation states.

Minimum requirements

Subscription

In order to purchase security compute units, you need to have an Azure subscription. For more information, see Create your Azure free account.

Security compute units

Security compute units are the required units of resources that are needed for dependable and consistent performance of Microsoft Copilot for Security.

Copilot for Security is sold in a provisioned capacity model and is billed by the hour. You can provision Security Compute Units (SCUs) and increase or decrease them at any time. Billing is calculated on an hourly basis with a minimum of one hour.

For more information, see Microsoft Copilot for Security pricing.

Capacity

Capacity in the context of Copilot for Security, is an Azure resource that contains SCUs. SCUs are provisioned for Copilot for Security. You can easily manage capacity by increasing or decreasing provisioned SCUs within the Azure portal or the Copilot for Security portal. Copilot for Security provides a usage monitoring dashboard for Copilot owners, allowing them to track usage over time and make informed decisions about capacity provisioning. For more information, see Managing usage.

Provisioning

We have 2 options to provision Compute Units, directly from the Copilot for Security Portal or from our Azure Subscription. The second option is to simply head over to Azure, search for Copilot for Security and you can create the resource, which in fact represents the billable CUs for the Directory the Subscription is associated with.

Authentication & Roles

It is important to have a good understating of the Roles and permissions that apply for Copilot for Security.

Copilot for Security roles

Copilot for Security introduces two roles that function like access groups but aren’t Microsoft Entra ID roles. Instead, they only control access to the capabilities of the Copilot for Security platform.

Copilot owner
Copilot contributor

By default, all users in the Microsoft Entra tenant are given Copilot contributor access.

Microsoft Entra roles

The following Microsoft Entra roles automatically inherit Copilot owner access.

Security Administrator
Global Administrator

Have a look at the relevant documentation page explaining everything about Roles & permissions:

Copilot in action

Once we have a good understanding and we have built our Team, we can start working with Copilot for Security within Defender Dashboards from https://security.microsoft.com.

Most Dashboards offer the interactive experience that helps us understand different signals, take potential actions and get explanatory suggestions from the Copilot.

Copilot for Security example — Threat Analytics – Copilot for Security

“Copilot for Threat Analytics is designed to assist users in understanding and responding to security threats. It provides evidence-based, objective, and actionable insights derived from security data. The purpose is to help users make informed decisions about their security posture and response strategies. It does this by analyzing data from various sources, identifying potential threats, and providing detailed information about those threats. This includes information about the nature of the threat, its potential impact, and possible mitigation strategies. The goal is to provide users with the information they need to effectively manage and respond to security threats.” (generated from Copilot for Security)

Copilot for Security Advanced Hunting — Defender Advanced Hunting – Copilot for Security

Especially in Advanced Hunting, Copilot offers a preset of KQL Queries that we can run directly or load them into our Editor for further editing.

Intune – Copilot the Endpoints

Yes you are reading correct! Once your Copilot Platform is ready you are in for a nice surprise! In Endpoint Management or Intune you will find Copilot ready to assist on your Endpoints Management Tasks! It is an integration in Preview, and i believe it is going to be a great addition for Endpoint Administrators.

If we wanted to list the functionality here is a list of the main points:

Input Processing: When you ask Copilot a question in Intune, it sends the query to Copilot for Security.
Data Sources: Copilot for Security uses data from your tenant and authoritative Microsoft documentation sources.
Response Generation: It processes the input and generates a response, which is then displayed in Intune.
Session Tracking: You can review all interactions in Copilot for Security by checking your sessions.
Privacy and Verification: Always double-check Copilot’s responses, as it may not always be accurate.
Partial Information: In some cases, Copilot might provide partial information due to large data volumes.

It is quite important to pay attention to the Responsible use of AI. A Frequently Asked Questions page is available for everyone as well.

Copilot for Security is a natural language, AI-powered security analysis tool that assists security professionals in responding to threats quickly, processing signals at machine speed, and assessing risk exposure in minutes. It draws context from plugins and data to answer security-related prompts so that security professionals can help keep their organizations secure. Users can collect the responses that they find useful from Copilot for Security and pin them to the pinboard for future reference. (source: Microsoft Responsible use of AI FAQ)

But that’s not all. Apart from the Defender portal, a good use of Copilot for Security comes within the Copilot for Security Platform. We can find a wide range of Prompts, we can utilize Plugins even build our own. We can upload files that provide guidance to the Copilot, examples of files you can upload are your organization’s policy and compliance documents, investigation and response procedures, and templates. Integrating this wealth of knowledge into Copilot allows Copilot to reason over the knowledge base or documents and generate responses that are more relevant, specific, and customized to your operational needs (source Microsoft Documentation).
