One of the biggest security risks in any organisation is unclear access. When users have permissions based on convenience instead of responsibility, security quickly becomes difficult to manage, audit, and trust. This is why Role-Based Access Control (RBAC) is a core concept in SC-900 (Microsoft Security, Compliance, and Identity Fundamentals). Understanding RBAC in SC-900 is ...

When most people hear the word identity, they think of a user account.In modern cloud security, that understanding is incomplete. In SC-900 (Microsoft Security, Compliance, and Identity Fundamentals), Microsoft makes one thing very clear: Security is not only about users — it’s about all types of identities. This includes users, devices, applications, and workloads.Understanding these ...

Microsoft Entra ID Overview in SC-900 Modern security starts with identity. In cloud and hybrid environments, networks are no longer the primary boundary. Users access applications from anywhere, on multiple devices, using cloud services that sit outside traditional perimeters. This is why Microsoft Entra ID is a core topic in SC-900 (Microsoft Security, Compliance, and ...

GRC Fundamentals in SC-900 Security is not only about blocking attacks.It is also about making the right decisions, managing risk, and meeting regulatory obligations. This is where GRC Governance, Risk, and Compliance becomes essential. In SC-900 (Microsoft Security, Compliance, and Identity Fundamentals), GRC is introduced to help learners understand how organisations control security responsibly, not ...

Encryption vs Hashing in SC-900 Data protection is a core theme in SC-900 (Microsoft Security, Compliance, and Identity Fundamentals), and one of the most commonly misunderstood topics is the difference between encryption and hashing. Many beginners assume these two concepts are interchangeable.They are not. SC-900 does not expect you to implement cryptographic algorithms or configure ...

Least Privilege Access in SC-900 One of the most common causes of security incidents is excessive access. Users often have permissions they no longer need, administrators have standing privileges, and applications are granted broader access “just in case.” When any of these accounts are compromised, attackers inherit all those permissions instantly. This is why Least ...

Zero Trust Model For many years, security was built on a simple assumption:If you are inside the network, you can be trusted. That assumption no longer works. Cloud services, remote work, mobile devices, and identity-based attacks have changed everything. Today, most security breaches do not break firewalls — they log in using stolen identities. This ...

Defense in Depth in SC-900 Security failures rarely happen because a single control was missing.They happen because multiple safeguards were absent or poorly layered. That is why Defense in Depth is a core concept in SC-900 (Microsoft Security, Compliance, and Identity Fundamentals). Microsoft does not rely on one tool or one security boundary. Instead, it ...

Shared Responsibility Model in SC-900 One of the most misunderstood concepts in cloud security is who is actually responsible for protecting what. Many organisations assume that once they move workloads to the cloud, security becomes the cloud provider’s job. Others assume the opposite — that everything still belongs to the customer. Both assumptions are wrong. ...

Conditional Access in SC-900 In modern Microsoft environments, access is no longer a simple allow or deny decision. Instead, access is evaluated dynamically based on identity, risk, device state, and context. This is where Conditional Access becomes one of the most important concepts in SC-900 (Microsoft Security, Compliance, and Identity Fundamentals). SC-900 does not expect ...
