What is the Microsoft Security Stack? - Complete Guide to Microsoft Security

Cybercrime has increased by 600% since the beginning of the global pandemic, so it's important to ensure that your organization is secure and compliant. While Microsoft has been a leader in the technology space for decades, more recently they have been focusing on building a robust and complete security stack. How can Microsoft help protect you from cybercriminals?

History of Microsoft Security

The road to security for Microsoft has been a rocky one. In late 1999, a small group of Microsoft employees banded together to create the Secure Windows Initiative (SWI), which attempted to raise software security awareness and search for bugs within code manually. After a terrible year for security in 2001 due to the worms CodeRed and Nimda infecting Internet Information Servers 4.0 and 5.0, the Windows Security Push was started to help change Microsoft's security landscape. This was an organization wide search to manually identify bugs in all software sold. Real change began when the Security Development Lifecycle was implemented, which included security as part of the process rather than a manual afterthought. 

Today, Microsoft takes cybersecurity incredibly seriously and is dedicated to helping advance security research. For the past few years Microsoft has invested $1 billion annually to cybersecurity research but has recently pledged to invest $20 billion over the next 5 years, including $150 million to expand the training network to help the US government upgrade their digital security needs. Microsoft now offers a full security stack, with products that are natively integrated in their current offerings as well as add-on products for other types of technology


What is the Microsoft Security stack? 

Microsoft has several different security applications that your organization can implement if it fits your needs. Let's explore these applications, their purpose, and some requirements: 

Microsoft Azure Sentinel


Microsoft Azure Sentinel offers next generation security operations with artificial intelligence. This is the first cloud-native security information and event management (SIEM) offered from a major cloud provider. This service will quickly find real threats that were previously undetected while minimizing false positives, investigate threats with AI, hunt for suspicious activities, and respond to incidents with automation. Azure Sentinel collects logs and event data from your applications, devices, networks, infrastructure, and systems to provide a holistic view of your IT security. Additionally, Microsoft claims that Sentinel is 48% less expensive and 67% faster to deploy than legacy on-premises SIEMs 

In order to utilize Azure Sentinel, you must have Azure Active Directory license and tenant or an individual account, an Azure subscription, relevant permissions for configuration, and a log analytics workspace to house all the data.

Microsoft Azure Security Center


Microsoft Azure Security Center is a unified infrastructure management system that will strengthen your data centers overall security posture. This provides advanced threat protection across all hybrid workloads in Azure or on-premises, by addressing rapidly changing workloads, protecting against increasingly sophisticated attacks, and providing security alerts and recommendations. Azure Security Center strengthens security posture as it assesses your environment and provides clarity of your resources and security.  

To utilize Azure Security Center, your organization must have a subscription to Microsoft Azure. The free tier of Azure Security Center is enabled in all Azure subscriptions, but Azure Defender can be added to give you full advantage of the advanced security management and threat detection capabilities.

Microsoft Cloud App Security

Microsoft's Cloud App Security is a cloud access security broker (CASB) which helps balance your IT teams need to support access while also protecting your organization's critical data. This safeguards your use of cloud services by enforcing pre-set security policies, and acts as a gatekeeper between your users and the cloud resources they are accessing. This addresses security gaps in the use of cloud services as it gives granular visibility and control over user activities and data. From providing data security, threat protection, and assistance in meeting compliance requirements, Cloud App Security is great for all organizations running in the cloud. 

Prerequisites for Cloud App Security are providing appropriate licensing for your users, correct admin access, and up to date web browsers. Some licenses like Microsoft 365 E5 have Cloud App Security included, but is can also be purchased as a stand-alone license. All users within your organization should be licensed to be protected through this function. Additionally, your IT leader will need global administrative or security administrative access in Azure Active Directory or Office 365 and an up-to-date web browser to configure this security offering. 

Microsoft Compliance Center


Microsoft Compliance Center provides easy access to the data and tools you need to meet your industry's compliance requirements. After choosing the compliance policy you'd like to meet, Microsoft Compliance Manager will provide a score of how compliant you currently are along with key action items to improve your score.  This can track your compliance journey to help with certifications, provide a place for compliance documents to reside, and give you step by step instructions to progress.  

Microsoft Compliance Center is available for all Microsoft 365 licensed users, but your IT leader must be a global administrator, a compliance administrator, or a compliance data administrator to begin configuration. Having other Microsoft security tools, such as Intune for mobile device management, can also help you to meet compliance goals.

For user owned devices, you can protect your organization's data through isolation. In either case, you can add and assign mobile apps to user groups or devices, configure apps to start or run with specific settings, update existing application, view reports on app usage, and do a selective wipe by removing organizational data. 

Intune is available as a stand-alone Azure service, but it is also included in several Microsoft licenses including Microsoft 365 E3 and E5, Microsoft 365 F1 and F3, Microsoft 365 G3 and G5, Microsoft 365 A3 and A5, Microsoft 365 Business Premium, Enterprise Mobility + Security E3 and E5, and Intune for Education.
