Tutorial / Cram Notes

Azure Policy evaluates resources in Azure by comparing the properties of those resources with business rules, as defined in policies, to look for violations. Once a policy or a group of policies is created, it can be assigned to specific scopes, such as management groups, subscriptions, resource groups, or individual resources.

A policy definition contains the following elements:

  • Policy Rule: This is the logic that evaluates the resource.
  • Parameters: These reduce the need for multiple policy definitions by allowing you to input specific values during assignment.
  • Effect: This determines what happens when a policy rule is matched (e.g., deny the resource, audit if it exists, or append additional configurations).

Azure Policy supports several types of effects that can be applied when a policy rule is matched:

  1. Deny: Blocks the resource from being created or updated.
  2. Audit: Generates a warning event in the activity log but doesn’t prevent the resource action.
  3. Append: Adds additional parameters or fields to the resource when it is being created or updated.
  4. AuditIfNotExists: Audits if a specific condition is not present.
  5. DeployIfNotExists: Deploys a resource if it does not already exist.
  6. Disabled: No effect on the resources; the policy is effectively turned off.

Example of Azure Policy Usage

Imagine an organization that needs to ensure all their virtual machines (VMs) are not exposed publicly. They could create a policy definition that denies public IP addresses from being associated with VMs. The rule would look for a public IP resource connected to a VM, and if found, the effect would deny the operation.

Compliance in Azure Policy

A key feature of Azure Policy is compliance assessment. The compliance dashboard in the Azure Policy center provides an aggregated view of the overall compliance state of the resources based on the assigned policies. It helps users quickly identify non-compliant resources and take appropriate actions.

Initiatives in Azure Policy

Initiatives are collections of policy definitions that are tailored towards achieving a particular overarching goal. Initiatives simplify the management of related policies by grouping them together. For example, an initiative for “Identity and Access Management” might include policies that enforce Multi-Factor Authentication (MFA) on accounts with access to sensitive data, and that audit the use of legacy authentication protocols.

Azure Policy in the Context of the SC-900 Exam

For the SC-900 Microsoft Security, Compliance, and Identity Fundamentals exam, it is important to understand the purpose and functionality of Azure Policy. The exam may cover topics such as:

  • Describing what Azure Policy is and its use cases
  • Knowing how to implement and manage Azure Policy
  • Understanding the different types of policy effects
  • How to interpret and take action on compliance data from Azure Policy
  • The role of initiatives in Azure Policy management

Azure Policy plays a significant role in ensuring that Azure environments align with security best practices, company standards, and regulatory requirements. It is an essential tool for governance and compliance in the Azure cloud, enabling organizations to automate and enforce policies across their Azure workloads.

Practice Test with Explanation

True or False: Azure Policy allows you to create, assign, and manage policies to enforce different rules and effects over your resources.

  • Answer: True

Azure Policy helps you manage and prevent IT issues with its policy-driven governance by creating, assigning, and managing policies.

What is the primary function of Azure Policy?

  • a) To manage virtual machines
  • b) To enforce organizational standards and to assess compliance at scale
  • c) To provide network security
  • d) To monitor service health

Correct Answer: b) To enforce organizational standards and to assess compliance at scale

Azure Policy is designed to enforce organizational standards and assess compliance at scale across resources.

True or False: Azure Policy can automatically resolve violations by creating a remediation task.

  • Answer: True

Azure Policy offers the ability to automatically remediate non-compliant resources through remediation tasks.

Which of the following can Azure Policies be applied to?

  • a) Resource groups
  • b) Subscriptions
  • c) Management groups
  • d) All of the above

Correct Answer: d) All of the above

Azure Policies can be applied at different scopes including resource groups, subscriptions, and management groups.

True or False: Azure Policy only audits resources in the location where the policy is applied.

  • Answer: False

Azure Policy can audit resources across different locations, not just the location where the policy is applied.

Azure Policy’s compliance evaluation happens:

  • a) Immediately after assignment
  • b) Every 24 hours
  • c) In real-time
  • d) Weekly

Correct Answer: b) Every 24 hours

Azure Policy performs a default compliance evaluation scan every 24 hours.

True or False: You can use Azure Policy as a security layer to block certain resources from being deployed.

  • Answer: True

Azure Policy can be set to a “deny” effect, which acts as a security layer to prevent prohibited resources from being deployed.

Which of the following features does Azure Policy include?

  • a) Policy definitions
  • b) Policy assignments
  • c) Policy parameters
  • d) All of the above

Correct Answer: d) All of the above

Azure Policy includes policy definitions, assignments, and parameters as its core features.

True or False: When you assign a policy in Azure Policy, it evaluates all resources within the scope immediately.

  • Answer: False

When a policy is assigned, the existing resources are evaluated during the next compliance scan, which happens within 24 hours by default.

Which Azure Policy effect audits whether a resource is compliant but does not enforce the policy?

  • a) Deny
  • b) Append
  • c) Audit
  • d) Disable

Correct Answer: c) Audit

The “audit” effect in Azure Policy logs the evaluation outcome but doesn’t enforce the policy.

True or False: Azure Policy initiatives are collections of multiple policy definitions that are tailored to achieve a single overarching goal.

  • Answer: True

Initiatives in Azure Policy are indeed collections of policy definitions designed to work towards a larger unified compliance goal or standard.

Compliance results within Azure Policy are available in which of the following formats?

  • a) JSON
  • b) XML
  • c) HTML
  • d) CSV

Correct Answer: a) JSON

The compliance details in Azure Policy are made available in JSON format for further analysis and reporting.

In my experience, tagging policies across multiple subscriptions has been quite useful. Anyone else using it like this?

One of the issues I’ve encountered with Azure Policy is a lag in policy enforcement during the initial assignment. Anyone faced the same?

For SC-900, knowing policy aliases can be very helpful. They allow you to scope your policy to specific properties.

Sonika Namnaik

I think Azure Policy is overly complicated and needs better documentation.
