Azure Policy is an essential service within Microsoft’s Azure cloud environment, central to administrating, enforcing, and auditing resource properties in Azure. Key to understanding Azure Policy within the context of the SC-900 Microsoft Security, Compliance, and Identity Fundamentals exam is recognizing its role in maintaining and enforcing resource standards, improving security posture, and tracking compliance within the organization.
How Azure Policy Works
Azure Policy works by evaluating your resources in Azure for non-compliance with assigned policies. The fundamental functioning of Azure Policy can be understood through the following steps:
Policy Assignment
An assignment is a policy definition that has been assigned to take place within a specific scope. This scope could be a management group, subscription, resource group, or an individual resource. Policy assignments function as an enforcement mechanism.
Policy Definitions
Policies in Azure are defined in a policy definition. Each definition contains conditions under which it is enforced. Policy definitions can be drafted with built-in JSON editor in Azure portal, or they can be custom made using Azure Resource Manager (ARM) templates. Policy definitions express what to evaluate and what action to take.
Policy Parameters
Parameters help in customizing policy definitions by providing the flexibility to reuse the policy definition for different scenarios.
Sample Policy Statement
For instance, a simple sample policy statement using “deny” effect in Azure Policy is as follows:
{
"if" : {
"source" : "action",
"equals" : "Microsoft.Storage/storageAccounts/write"
},
"then" : {
"effect" : "deny"
}
}
In this policy statement, the action “Microsoft.Storage/storageAccounts/write” is evaluated, and if it matches the condition, the effect of “deny” is implemented.
Azure Policy and Compliance
Azure Policy plays a significant role in ensuring compliance within Azure. It provides a compliance dashboard from where you can get an overview of your current compliant and non-compliant resources. The Azure Policy compliance engine runs evaluations for each assigned policy, and reports the results in the compliance blade.
It also provides comprehensive assessment results for built-in initiatives like the Azure Security Benchmark. This can assist organisations in tracking their compliance with industry standards and regulations.
Azure Policy Importance for SC-900 Exam
Azure Policy is particularly important from the perspective of the SC-900 Microsoft Security, Compliance, and Identity Fundamentals exam because it aligns with the key concepts of security, compliance, and identity that the exam focuses on.
- Security: Azure Policy enforces security by ensuring that resources conform to certain conditions – for instance, it could ensure that all storage accounts enforce HTTPS traffic.
- Compliance: Through regular evaluations and the compliance blade, Azure Policy helps maintain compliance with industry regulations and standards.
- Identity: From an identity perspective, Azure Policy can also control access to Azure resources, functioning as part of your wider Identity and Access Management strategy.
Conclusion
In conclusion, Azure Policy is a vital tool for administrators managing resources in Azure, allowing them to define, enforce, and audit policy standards throughout their environment. Understanding Azure Policy is an important component of the SC-900 exam, which places emphasis on the ability to handle security, compliance, and identity within the Azure environment.

Interview Questions
What is Azure Policy?
Azure Policy is a service in Azure that users use to create, assign and manage policies. These policies enforce different rules and effects over resources, so users stay compliant with their corporate standards and service level agreements.
What is the function of Azure Policy in resource management?
Azure Policy enforces organizational compliance by ensuring that resources in your Azure subscriptions conform to certain rules and standards. It assesses, audits, and mitigates resource configurations across all resources or a subset of them.
Can Azure Policy be used across multiple subscriptions?
Yes, Azure Policy has a scope that can range from a management group to a single resource, allowing it to enforce policies across multiple subscriptions.
What value does Azure Policy bring to an organization’s security posture?
Azure Policy provides a unified way to implement governance and assess compliance at scale. It helps organizations stay compliant with external regulations and internal policies by enforcing rules to manage resources.
What is the function of Policy Definition within Azure Policy?
Policy Definition expresses what to evaluate and what action to take. For example, it can specify that virtual machines should have Endpoint Protection enabled, preventing unwanted resources.
Can you impose restrictions based on location using Azure Policy?
Yes, one of the standard policies in Azure is that resources can be permitted or denied in certain locations. This helps to ensure compliance with regulations and corporate guidelines related to data residency.
What are Initiatives in Azure Policy?
Initiatives are a collection of policy definitions that are set with the intent of achieving a singular overarching goal. They simplify the process of managing and assigning policy definitions.
What is the purpose of Policy Assignment in Azure Policy?
Policy Assignment is the act of applying a policy or initiative to a specific scope, such as a resource group, subscription or management group.
What is the difference between Azure Policy and Azure Role-Based Access Control (RBAC)?
While both are used for governance, they serve different purposes. Azure Policy is used for enforcing rules on resource configurations to ensure compliance, whereas Azure RBAC is used for managing who has access to Azure resources.
Can Azure Policy apply to both existing and new resources?
Yes, Azure Policy applies to both existing and new resources. It helps to enforce compliance to corporate standards for all resources in an Azure environment.
How does Azure Policy assist in financial governance?
Azure Policy can help with financial governance by setting quotas on the amount of expenditure for a department or project, limiting the types of resources that can be provisioned, and ensuring offerings are correctly tagged for chargeback.
Is it possible to customize Azure Policy?
Yes, users are able to customize Azure Policy by creating their own policy definitions. These custom policies can then be assigned to a scope just like any other built-in policy.
Can Azure Policy be used to enforce tagging strategies?
Yes, Azure Policy can be used to enforce and manage tagging strategies, ensuring required metadata is associated with each resource.
Can Azure Policy be used for Compute Isolation?
Yes, Azure Policy can ensure compliance for compute isolation requirements by keeping different workload types separate using techniques such as tagging.
How does Azure Policy contribute to an organization achieving Data Sovereignty?
Azure Policy contributes to achieving data sovereignty by enabling policies that restrict the deployment of resources to certain geographical regions, ensuring data is stored in a location according to organizational or regulatory needs.
