Protecting Azure Resources Against Accidental Changes

Protecting Resources in Azure Against Accidental Changes

Azure offers various tools and mechanisms designed to prevent unintended modifications and unwanted deletions of your cloud resources. In this article, we'll explore three core levels where such protection can be applied — subscription, resource group, and individual resource — along with specific strategies to safeguard them.

Subscription Protection

Subscriptions act as containers for organizing and managing related resources within your Azure environment. To protect against accidental changes affecting multiple resources under one subscription, consider enabling subscription policies. These policies allow administrators to define rules governing the creation, modification, and deletion of resources across their entire Azure environment, ensuring compliance and preventing mistakes.

To safeguard your subscription against unauthorized access, make sure to configure Access Control (IAM) settings carefully by assigning appropriate roles to users or services based upon their privileges. This control layer also helps detect potential misuse by auditing activity logs.

Resource Group Level Protection

A resource group is a logical container used to organize and manage related resources like storage accounts, virtual machines, and app services together. For added security and ease of management, it's recommended to apply locks to resource groups, which restrict application of any changes. Locks come in two types: Read-only locks and Delete-only locks, with varying degrees of permissions. The former prevents updates and deletions while allowing reads; the latter permits only removal actions without modifying existing data.

Additionally, deploying blueprints grants further flexibility when creating, updating, and deleting resources throughout your organization, providing guidelines consistent with company standards and regulatory requirements while minimizing errors during deployment.

Individual Resource Protection

At the lowest level, protecting individual resources involves three primary approaches: Resource Locks, Backups & Restores, and Alerts.

Resource Locks: Similar to locking a resource group, individual resources can have locks assigned limiting specific operations. As mentioned earlier, these locks can range from Read-Only to Delete-Only settings.
Backups & Restore: Azure provides features for backing up and restoring resources such as SQL Databases, Virtual Machines, Storage Accounts, etc., reducing risks posed by accidental changes.
Alerts: When configuring alerts, monitor important events that might indicate vulnerability due to misconfigurations or other issues. Customize alert triggers to suit your needs, ensuring swift action whenever incidents occur.

In addition to these measures, implementing automation through scripting or toolkas like Azure DevOps Pipelines enables monitoring, auto-scaling, and reconfiguration tasks, enhancing resource resilience against human error.
