Are you ready to master the fundamentals of Microsoft security and ace the SC-900 certification exam? This comprehensive guide dives deep into the core concepts of security, compliance, and identity to help you protect your organization in a cloud-first world. Join Mir Peters in this first episode of our Microsoft Security Podcast series as we transform you from a security novice into a confident professional.

In this video, we explore why security and compliance are now non-negotiable for modern businesses. You will learn about the shared responsibility model, which clarifies the division of duties between you and your cloud provider across IaaS, PaaS, and SaaS environments. We also break down the defense in depth strategy, showing you how to build a multi-layered fortress around your data using physical, network, and application-level safeguards.

As the digital landscape evolves, we discuss why identity has become the new security perimeter. We cover the transition to a zero trust mindset, focusing on explicit verification and the principle of least privilege. You will also gain a clear understanding of technical essentials like encryption and hashing, as well as the governance, risk, and compliance framework. Whether you are preparing for an exam or looking to implement practical security steps using tools like Microsoft Entra ID and Microsoft Purview, this session provides the roadmap you need for success.
