Over the past few years, Microsoft has implemented better Security features into all of its cloud offerings. Microsoft Defender capabilities are now very sophisticated and offer deep inspection into not only cloud services but also on-premises from Windows 10 devices.
The "Microsoft Defender Security Center" is your central entry point to identify, potential breach activity, overall security score, and threat analytics.
If you have the required license, you can access the dashboard from here: https://securitycenter.windows.com/dashboard.
Once authenticated, the primary Security operations dashboard loads displaying the following:
Each report allows you to click into further details. For example, clicking on the "Suspicious process injection observed" takes me to all the features needed to investigate further.
Upon clicking further, firstly, you are presented with base details of the overall issue and recommended actions. The actions drop down allows you to drill deeper and see, for example, the "Timeline" of events.
For example, looking deeper into this injection, we can see that an "Anomalous memory allocation" was identified within "PowerShell."
Clicking further into the backdoor reveals the command line used as well as process name, execution time, and process id.
Going back to the specific injection, we can use the "Alert process tree" to see the identified anomalous process.
To get a better view of attacks like this, we can expand the menu item "Automated investigations" and click the first sub menu item.
Clicking into any of the same observed injections will display the "Investigation graph" that identifies any Alerts, Machines, Key findings, Entities, Logs and offers specific Actions.
If we now click on the "Threats found" icon, the "Key findings" are listed.
If we now click on a row, we can then complete the "Approve or Reject" action.
As you can see, the tooling is excellent at traversing an observed anomaly or malicious attack. If we expand the "Threat & Vulnerability Management" menu and click "Dashboard," we get a breakdown of our security posture based on a detailed analysis of the tenant.
You can also see in the bottom table a list of software that either needs patching, is out of date or is vulnerable.
Clicking onto the "Windows 10" row displays further details. If you then click "Open software page," and then click "Update Windows 10", you are presented with a list of the "Exposed machines" and "CVEs" that are addressed by the various patches.
The last thing that is extremely helpful is the "Security recommendations." It provides a simple list of activities for completion, that will increase your overall security.
All in all, "Windows Defender ATP" and the other components of the "Microsoft Defender Security Center" are advanced enough to protect all areas of your cloud-connected infrastructure.
I spend most of my time working with organizations who are either considering, migrating, or have already migrated to Azure or Microsoft 365. Most of the conversations that organizations have are related to the cool new features that are available and how the end-users will be empowered to use them. On the flip-side, though I also have many conversations after companies have moved to Office 365, and that conversation usually is around how they can stop access, control sharing or best practice security capabilities in the service.
One critical area but a not so sexy topic is alerting and logging. Honestly, there are not many organizations that their first conversation about moving to the cloud is "what logging can we get, and I want lots of alerts." It is a boring subject, whether you are still using on-premises, cloud, or hybrid services. No IT or Security team enjoys looking at log files or receiving millions of alerts about user activity; however, it is a critical factor in a successful deployment and migration to the cloud.
Will we still be looking at logs in the cloud?
Yes, you will. Everything within the Microsoft 365 cloud platform gets logged and captured. Running within the service itself is Microsoft Telemetry platform that captures all kinds of information based on different signals. Then you have each application that logs values such as errors, activities to security issues. On top of that, you have all of this data normalized and then made available in various forms such as through log tools, web interfaces to the Restful APIs and Graph endpoints.
Security alerting and the Azure Security Center?
Alerts are the notifications that the Azure Security Center generates when it detects threats on your resources. It prioritizes and lists the alerts along with the information needed for you to investigate the problem quickly. To detect real threats and reduce false positives, the Azure Security Center collects, analyzes, and integrates log data from all Azure resources, the network, and other solutions, such as the firewall and endpoint protection. Azure Security Center analyzes this information, correlating information from multiple sources, to identify threats. If you are using on-premises and hybrid cloud, then the Azure Security Center can monitor those resources.
Security incidents in the Azure Security Center
A security incident is a collection of related alerts, instead of listing each alert individually. The Azure Security Center uses fusion to correlate different alerts and low fidelity signals into security incidents. Using incidents, the Azure Security Center provides you with a single view of an attack campaign and all of the related alerts.
How can I use the Azure Security Center?
The Azure Security Center is enabled with your Microsoft Azure subscription and accessed from the Azure portal. The Security Center is available in two tiers. The Free tier provides visibility into the security state of your Azure resources, basic security policy, security recommendations, and integration with security products and services from partners. The Standard tier adds advanced threat detection capabilities, including threat intelligence, behavioral analysis, anomaly detection, security incidents, and threat attribution reports.

Today Liam Cleary is renewed as a Microsoft Most Valued Professional (MVP) for "Office Apps and Services" for the 13th year in a row. MVP's get recognized as leaders in their fields, and for their work in the technology community. Liam is well known for speaking at conferences, webinars, and content authoring. He has a great passion for helping others be successful with technology. As an author for Pluralsight, Opsgility, and LinkedIn, he spends a lot of his time creating content to help others.
Liam is looking forward to another year in the MVP community and helping others.
A lot of our work is helping organizations to secure either Office 365 or the full Microsoft 365. In all of the work, the most common issue or problem is lack of knowledge of where to start. In fact, during a research project we worked on last year, that was a significant factor in why many organizations had suffered breaches even within Microsoft 365. Microsoft is doing a great job documenting the practical steps for a specific feature, function, or component, but you are often left reading very generic examples that don't quite for your scenario.
We were asked to help by writing a white-paper that is based around the question and answers idea. For example, a few common questions we often get are:
Can I be notified of potential user malicious behavior such as mass file downloads?
Can I apply a content security policy to a document no matter where it resides?
How can I ensure that personally identifiable information never leaves the organization?
How can we protect personal devices that connect to Office 365 services?
The purpose of the white-paper we produced is to answer questions rather than outline technical documentation. If you are interested in this, then head over to the link below:
Though the reading is excellent, that may not help you identify issues right now that need resolving. Introducing the Microsoft 365 Secure Score. You can access this for your tenant using this link. As soon as it loads, click the 'Improvement actions,' to see the list of identified items for improvement, as well as details of what that means.
Clicking into items reveals further details, including the following:
As you can see, this is such a simple thing to review with essential details on why the specific feature or component is critical and needs enabling or configuring. Don't hesitate, head over to the 'Microsoft 365 Secure Score' pages to improve your security posture.
