To do this, Azure offers several options, allowing for varying degrees of customization and granularity.
Azure Policy helps enforce organizational standards and to assess compliance at scale. Through its compliance dashboard, it provides an aggregated view to evaluate the overall state of the environment, with the ability to drill down to the per-resource level.
Here’s a step-by-step guide on how to create a custom Azure Policy:
For example, consider a policy that enforces the use of a specific SKU for virtual machines:
{
“if”: {
“allOf”: [
{
“field”: “type”,
“equals”: “Microsoft.Compute/virtualMachines”
},
{
“not”: {
“field”: “Microsoft.Compute/virtualMachines/sku”,
“equals”: “Standard_B2s”
}
}
]
},
“then”: {
“effect”: “deny”
}
}
This policy will block the creation of virtual machines that are not of the specified SKU.
Azure Security Center provides advanced threat protection and unified security management, and also allows organizations to create custom security policies using Azure Policy.
Role-Based Access Control (RBAC) allows you to define fine-grained access management for Azure. Custom roles can be created to provide tailored permissions that are not available in the built-in roles.
For example, a custom role that allows reading everything but denies access to delete any resource would look like the following in JSON format:
{
“Name”: “Custom Read-Only Role”,
“IsCustom”: true,
“Description”: “Can view everything but not delete any resources.”,
“Actions”: [
“*”
],
“NotActions”: [
“*/delete”
],
“AssignableScopes”: [
“/subscriptions/{subscription-id}”
]
}
Azure Active Directory (Azure AD) Conditional Access policies provide granular access control based on conditions.
Each of these methods for customizing security policies in Azure serves a distinct purpose. Azure Policy enforces organizational standards and compliance, Azure Security Center’s custom policies provide targeted security recommendations, RBAC restricts actions at a fine-grained level, and Azure AD Conditional Access controls access based on conditions. Together, these tools enable a comprehensive and customized security posture tailored to an organization’s specific needs within the Azure environment.
Answer: False
Explanation: Azure Policy supports the creation of custom policies in addition to the built-in policies provided by Azure.
Answer: Azure Policy
Explanation: Azure Policy is used to create, assign, and manage policies to enforce rules and effects across multiple Azure subscriptions.
Answer: True
Explanation: Azure allows you to assign policies at various levels including the management group, subscription, resource group, and individual resource.
Answer: Azure Policy Definition Language (JSON)
Explanation: Azure custom security policies are defined using Azure Policy Definition Language, which is a JSON-based structure.
Answer: True
Explanation: Azure Policy includes the deployIfNotExists policy definition that can automatically deploy a remediation task if the policy is not complied with by the existing resources.
Answer: All of the above
Explanation: Azure Policy definitions can include various effects such as Deny, Audit, Append, and DeployIfNotExists to manage and enforce policies.
Answer: False
Explanation: Azure policy compliance data is not real-time; it’s evaluated at a regular interval, and it can take up to 24 hours for the policy state to be updated.
Answer: To group together and manage several related policies
Explanation: The initiative definition in Azure Policy is used to group together a set of related policy definitions to achieve a specific governance goal.
Answer: False
Explanation: Azure Policy supports the use of both managed and unmanaged identities within the context of policy assignments, not just policy definitions.
Answer: Mode and Parameters
Explanation: When defining a custom security policy in Azure, the first two major parts are the ‘mode’ and ‘parameters’. Mode determines which resource types will be evaluated by the policy, and parameters are used to provide flexibility in policy execution.
Answer: False
Explanation: An Azure security policy can be updated or changed after assignment. However, care should be taken as changes may affect the compliant/non-compliant status of resources.
Answer: Once a day
Explanation: Azure Policy evaluation cycle runs by default once every 24 hours. However, you can manually trigger a re-evaluation if you don’t want to wait for the automatic cycle.
Azure Policy is a service in Azure that allows users to create, assign, and manage policies that enforce compliance with rules and guidelines for resources in their organization.
You can create and manage Azure Policy through the Azure portal, Azure PowerShell, Azure CLI, and Azure REST API.
A custom policy definition in Azure Policy is a set of conditions that specify compliance rules for resources in an organization.
A policy assignment in Azure Policy is a way to apply a policy definition to a scope of resources, such as a subscription or resource group.
You can create a custom policy definition in Azure Policy using the Azure portal, Azure PowerShell, or Azure CLI.
An initiative in Azure Policy is a collection of policy definitions that are grouped together to achieve a specific goal or compliance requirement.
You can create and manage an initiative in Azure Policy using the Azure portal, Azure PowerShell, or Azure CLI.
Azure Policy Guest Configuration is a service that provides compliance monitoring and enforcement for virtual machines and other resources.
You can use Azure Policy with Azure Key Vault to enforce policies that govern the access and use of key vault resources.
Azure Policy compliance is a measure of the extent to which resources in an organization meet the compliance rules specified in the policy assignments.
