RBAC vs. ABAC in Azure: Why You Need Both for Cloud Access Control That Actually Works

Let’s cut to the chase, cloud access control isn’t just a checkmark on your compliance list anymore. It’s a daily battlefield. With global teams, hybrid workloads, and rising security risks, who can do what and under what conditions is now a core pillar of IT strategy.

If you’re working in Azure, you’ve likely heard of RBAC (Role-Based Access Control) and ABAC (Attribute-Based Access Control). But what you may not know is that these aren’t mutually exclusive instead they’re better together.

Let’s unpack what each model does, where they shine (and struggle), and how to combine them for airtight, scalable access governance in Azure.

What is Azure Role-Based Access Control (RBAC)?

Azure RBAC helps you control access by assigning roles to security principals (users, groups, service principals, or managed identities) at a specific scope (subscription, resource group, or resource).

Each role is a bundle of permissions, think of them as job descriptions for Azure resources.

Example RBAC Use Cases

  • A user who can manage only virtual machines in the Dev subscription.
  • A group assigned the Reader role at the resource group level.
  • An app given Contributor access to only one storage account.

RBAC works well when your access needs are role-based and relatively straightforward. But as organizations scale and become more dynamic, things can get messy fast.

Where RBAC Falls Short

RBAC starts to creak when:

  • You need to create roles for every unique mix of region, team, and resource.
  • You end up with a Frankenstein monster of roles like:
    • VP - Europe
    • Manager - Asia
    • SalesRep - NorthAmerica - Junior
  • You have hierarchical or multi-tenant data structures that don’t fit RBAC’s flat model.

The result? Role sprawl, administrative pain, and security gaps.

What is Azure Attribute-Based Access Control (ABAC)?

ABAC adds contextual smarts to access control. Instead of relying solely on roles, it factors in attributes of:

  • The user (e.g., department = HR)
  • The resource (e.g., tag = Project:Alpine)
  • The environment (e.g., access during business hours only)

In Azure, ABAC is implemented through role assignment conditions that filter RBAC permissions.

ABAC in Action

  • “Chandra can read blobs only if they’re tagged with Project=Cascade.”
  • “Support engineers can impersonate users only during a help session.”
  • “Users can access data only in their assigned region or cost center.”

This kind of fine-grained access is powerful, flexible, and crucial in multi-tenant, regulated, or fast-moving environments.

RBAC + ABAC: Not a Choice – A Collaboration

Here’s the mindset shift: RBAC and ABAC are not competing models. They’re complementary.

RBAC defines what actions are allowed.
ABAC defines under what conditions those actions are allowed.

By combining the two, you can:

  • Keep your role structure simple and understandable.
  • Layer on access conditions that reflect real-world business rules.

Common Hybrid Patterns

ScenarioRBAC RoleABAC Condition
Multi-tenant appTenant AdminOnly for tenant_id=X
Regional accessSales ManagerRegion = “North America”
Subscription tiersPremium UserAccess feature only if plan=premium
File accessEditorOnly owner=user_id or shared_with=user_id
Support scenariosSupport AgentImpersonation allowed if user_in_session=true

Best Practices for RBAC and ABAC in Azure

Let’s bring it home with the golden rules:

RBAC Best Practices

  • Least Privilege Always: Grant only the permissions needed—nothing more.
  • Limit Subscription Owners: Three max. The fewer, the safer.
  • Use PIM for Just-in-Time Access: With Microsoft Entra PIM, elevate access temporarily.
  • Assign Roles to Groups: Not individuals. Makes scaling and auditing easier.
  • Avoid Wildcards in Custom Roles: Be explicit with Actions and DataActions.
  • Script with Role IDs, Not Names: Avoid breakage from renamed roles.

ABAC Best Practices

  • Tag Strategically: Use meaningful tags like Project, Environment, or Classification to enable ABAC.
  • Use Conditions to Reduce Role Sprawl: Filter access with precision.
  • Start Small: Pilot with blob storage conditions before scaling ABAC elsewhere.
  • Don’t Replace RBAC: Use ABAC as a filter, not a replacement.

Recap: When to Use What

Final Thoughts

RBAC gives you structure. ABAC gives you nuance. In Azure, using both gives you power and precision.

Don’t fall into the “either/or” trap. The real magic happens when you combine the predictability of RBAC with the intelligence of ABAC to build access models that scale with your business.

Azure’s Default Outbound Access Is Being Retired: What Cloud Admins Need to Know (and Do)

If you’re an Azure architect or admin and thought “default outbound access” was your silent wingman for VM connectivity, surprise! Microsoft is retiring it. After September 30, 2025, all new virtual networks in Azure will no longer support default outbound Internet access. Translation? If you’re spinning up VMs and expecting magic public IP access without configuring anything, those days are numbered.

Let’s break down what’s happening, why it matters, and how to prepare without losing your mind.

What’s Being Retired?

Historically, Azure has provided what’s called default outbound access to virtual machines that don’t have an explicitly defined method of reaching the internet. Think of it as Azure tossing a temporary, shared public IP behind the scenes so your VM can connect out.

But that’s going away for all new VNETs after September 30, 2025.

  • Existing VNETs using default outbound access? You’re safe… for now.
  • New VNETs? You’ll need to be explicit.

No more “it just works” surprises. And honestly? That’s a good thing.

Why Is Microsoft Doing This?

Because “default” often equals “risky.” Here’s why the implicit setup has been problematic:

  • Unowned IPs: The IP addresses used for default outbound access are owned by Microsoft, not you. If they change, your workloads can break. And good luck explaining that to your CISO.
  • Lack of Visibility: These IPs aren’t traceable to your tenant, complicating logging and egress controls.
  • Zero Trust FTW: The shift aligns with modern security practices, explicit is better than implicit. You want to control your perimeter, not let Azure make assumptions for you.

This is a “secure by design” decision. We’re moving away from “let’s hope it works” to “I know exactly what’s happening and why.”

What You Need to Do Now

If you’re still relying on default outbound access in existing deployments: start transitioning. For all new virtual networks, you’ll need to plan outbound access explicitly. Microsoft recommends one of the following methods:

Explicit MethodWhen to Use It
Azure NAT GatewayBest practice for scalable, consistent outbound IP
Standard Load Balancer (SLB)Use when you already load-balance traffic
Public IP on NICUse when only one VM needs public connectivity

Bonus: Disable Default Access Explicitly

Even before the cutoff, you can preemptively disable default outbound access by enabling “Private Subnet” on your VNET or via PowerShell/CLI/ARM templates. Here’s the PowerShell approach:

$resourceGroupName = "<your-rg>"
$vnetName = "<your-vnet>"

$vnet = Get-AzVirtualNetwork -ResourceGroupName $resourceGroupName -Name $vnetName

foreach ($subnet in $vnet.Subnets) {
$subnet.DefaultOutboundAccess = $false
}

Set-AzVirtualNetwork -VirtualNetwork $vnet

Why do this? Because some services like Windows Update and Windows Activation require explicit outbound connectivity anyway. Plus, it’s future-proof.

Gotchas to Watch Out For

  • Fragmented packets & ICMP: Not supported with default outbound IPs.
  • Multiple NICs or VMSS: IPs can change unpredictably when scaling.
  • NIC-level detection: Azure Advisor will still report default outbound usage unless the VM is rebooted after changing egress method.

Also note: Flexible orchestration mode for VMSS never uses default outbound. It’s already secure-by-default.

What’s Next?

Microsoft is nudging (okay, shoving) us toward better security hygiene. This is your nudge to revisit those old Terraform templates, ARM deployments, and quick-and-dirty test setups that assumed default behavior.

Checklist before September 30, 2025:

  • Inventory VMs using default outbound access
  • Decide on your preferred outbound method (NAT Gateway is a strong default)
  • Update IaC templates
  • Communicate with app teams about the change
  • Test egress-dependent services (patching, activation, APIs)

Final Thoughts

This isn’t just another checkbox compliance update, this is about control, visibility, and security. By requiring explicit egress, Microsoft is giving you more authority over your architecture.

It’s also a good reminder: just because something works “by default” doesn’t mean it should.

Understanding billing account for Microsoft Customer Agreement (MCA)

Let’s be honest, cloud billing isn’t exactly the most exciting topic. But do you know what’s worse? Opening your Azure bill and feeling like you need a detective’s magnifying glass to figure out what’s going on.

If you’ve got a Microsoft Customer Agreement (MCA), understanding your billing account is key to keeping your cloud costs in check and avoiding any surprise charges. So, grab a coffee, and let’s break it down in a way that actually makes sense.

What is an MCA Billing Account (And Why Should You Care)?

Think of your MCA billing account as the command center for all your Azure charges. It’s where you manage invoices, payments, and who gets to see (or mess with) your billing details. If Azure billing were a Netflix account, your billing account would be the primary profile, the one that controls everything.

Key Things Your MCA Billing Account Lets You Do:

  • View and manage invoices and payment methods
  • Set up multiple billing profiles for different teams or departments
  • Assign roles and permissions (so not everyone can max out the budget!)
  • Track spending across subscriptions

If you’re managing an MCA billing account, congrats! You’ve got the keys to the financial kingdom, use them wisely.

Azure Billing Account: The Big Picture

Your Azure Billing Account is the home base for all things billing-related in your MCA. It’s where invoices, payments, and spending details live. If you think of Azure like a streaming service, your billing account is your main subscription, everything starts from here.

What You Can Do with an Azure Billing Account:

  • View and manage invoices
  • Set up and control billing profiles
  • Assign billing roles to different users
  • Track spending across all subscriptions

This is your financial cockpit, control it wisely!

Billing Profiles: Keeping Budgets Organized

A Billing Profile is like a separate tab on your credit card statement for different teams, projects, or departments. Instead of one giant invoice that makes your head spin, you can split up costs for better organization.

Why Billing Profiles Matter:

  • They generate separate invoices for different teams.
  • You can set up different payment methods for each profile.
  • They help track spending more effectively.

So, if your company has an AI research team and a DevOps team, they can each have their own billing profile, no messy financial mix-ups!

Invoice Sections: Breaking Down Costs Clearly

Under each Billing Profile, you have Invoice Sections. Think of these as subfolders inside your billing profiles, perfect for breaking down costs by project, department, or even specific environments (like Dev vs. Production).

How Invoice Sections Help:

  • You can group charges logically (e.g., marketing vs. engineering).
  • It makes cost tracking super clear.
  • Helps with financial reporting—no more guessing where money went!

If Billing Profiles are the different tabs on your statement, Invoice Sections are like itemized charges, they give you a clearer breakdown.

Subscriptions: Where the Magic Happens

Your Azure Subscriptions are where your actual cloud services live, virtual machines, databases, AI services, you name it. But each subscription needs to be linked to a Billing Profile to be paid for.

Key Things to Know About Subscriptions:

  • They inherit billing settings from their assigned billing profile.
  • You can have multiple subscriptions under one billing account.
  • Each subscription can be assigned to an Invoice Section for better tracking.

Think of it like multiple mobile lines on a family plan. Each line (subscription) has its own usage, but they all roll up into the main bill (billing profile).

Optimizing and Tracking Azure Costs

To effectively manage and optimize your Azure expenditures, consider the following practices:

  • Strategic Structuring: Align your billing profiles and invoice sections with your organization’s hierarchy or project structure. This alignment ensures that invoices reflect your internal financial organization, simplifying reconciliation and reporting.
  • Role-Based Access Control: Assign appropriate roles to team members based on their responsibilities. Azure offers various billing roles, such as Billing Account Owner, Billing Profile Owner, and Invoice Section Owner, each with specific permissions. Implementing role-based access ensures that individuals have the necessary access to perform their tasks without compromising security.
    • Billing Account Owner – The supreme leader of the billing universe. Full access.
    • Billing Profile Owner – Controls billing for one profile (but not the entire account).
    • Billing Profile Contributor – Can manage invoices and payments but not assign roles.
    • Billing Reader – Can see invoices but can’t touch them (great for finance teams!).
  • Regular Monitoring: Utilize Azure’s cost management tools to monitor spending across different billing profiles, invoice sections, and subscriptions. Regular analysis helps in identifying trends, detecting anomalies, and making data-driven decisions to optimize costs.
  • Budgeting and Alerts: Set up budgets and configure alerts for your billing profiles and invoice sections. Proactive notifications enable you to address potential overspending promptly, ensuring adherence to financial plans.

Pro Tips to Avoid Billing Headaches

  1. Assign Roles Wisely – Not everyone needs full access! Keep spending power in the right hands.
  2. Use Billing Profiles for Better Organization – Split billing by department or project to track spending easily.
  3. Enable Cost Management Tools – Azure has built-in cost tracking to help you avoid end-of-month surprises.
  4. Regularly Review Invoices – Set up a habit of checking your invoices to catch any unexpected charges.

Final Thoughts: Take Control of Your Azure Billing

Understanding your MCA Billing Account isn’t just about paying bills, it’s about controlling costs, organizing expenses, and making sure your finance team doesn’t hunt you down.

So next time you log into Azure, don’t panic at your invoice. Instead, think:

  • Is my billing organized?
  • Am I using Billing Profiles and Invoice Sections properly?
  • Do I need to adjust roles to keep spending in check?

Avoid the Oops: Proactively Monitor Entra Application Secret Expirations with Automation

In the fast-paced world of enterprise IT, even small oversights can lead to major disruptions. One of those easily overlooked, yet critically important tasks is, monitoring Microsoft Entra (formerly Azure AD) application secret expirations.

Imagine this: everything is running smoothly in production until — bam! — an app suddenly fails because its secret expired. No alerts, no heads-up, just user complaints and a flurry of incident reports. Sound familiar?

Why Monitoring Application Secrets Matters

At its core, application secrets are credentials that apps use to authenticate themselves with Microsoft Entra ID. But unlike passwords, secrets come with an expiration date. If they aren’t renewed in time, the app’s authentication fails and with it, the business processes it supports.

For organizations running dozens (or hundreds) of app registrations, staying ahead of these expirations is not optional, it’s essential. Secrets that silently expire can grind systems to a halt, disrupt integrations, and worst of all, trigger security incidents or SLA breaches.

A Common Problem in the Real World

When I first set out to automate monitoring for app secret expirations, I assumed it’d be simple. A few PowerShell lines here, an API call there, maybe some Logic App magic… problem solved, right?

Well, not quite.

Most of the tutorials and blog posts I found focused solely on fetching the expiration date of secrets — they showed how to query the data, but not how to operationalize it. I wanted something that would proactively notify the right people before things went south.

Eventually, I came across a helpful post on Microsoft Tech Community:
Use Azure Logic Apps to Notify of Pending AAD Application Client Secrets and Certificate Expirations

It was a solid foundation. The Logic App would periodically check secrets and send an email notification if one was nearing expiration.

But then… I hit a snag.

If an application had multiple owners which, in the enterprise world, is very common the Logic App would only notify the first listed owner. Everyone else? Left in the dark.

Not ideal. Especially when that one person is on PTO, has left the company, or, let’s be honest, just ignores emails from IT.

So, I decided to roll up my sleeves and build a PowerShell-based solution that:

  • Queries all app registrations
  • Checks for secrets or certificates nearing expiration
  • Looks up all owners (not just the first one)
  • Sends clear, actionable email notifications to each owner

Why Automate This? Let’s Talk Benefits

Here’s why every enterprise IT team should care about automating secret expiration alerts:

  • Proactive Security – Timely notifications help you spot secrets that are about to expire, before they become a security risk or business disruption. It’s the difference between being reactive and being prepared.
  • Reduced Downtime – Missed secret expirations lead to failed authentications, which means broken apps. Proactive alerts buy you time to renew secrets and avoid outages.
  • No More Manual Tracking – Maintaining a spreadsheet of app secrets? Been there. Done that. Automation means less grunt work and fewer mistakes.
  • Smart Notifications – By targeting all app owners, not just the first in line: you’re covering your bases. Even if someone’s on vacation, someone else sees the alert and can take action.

What This Script Does

  • Authenticates to Microsoft Graph with the required permissions
  • Queries all Entra app registrations
  • Identifies app secrets and certificates that are expiring within a defined threshold (e.g., 30 days)
  • Pulls all assigned owners for each app
  • Sends an email notification to each owner with details about the impending expiration
  • Sends an email notification to an administrator email, a distribution group or a shared mailbox containing a list of all secrets that are expiring

Use task scheduler to run this script from your on-premise environment. You can securely store the credentials to be used in the PowerShell script using the SecretManagement module. I’ve covered this in detail in an earlier post here. The ideal and preferred method is to use Azure automation account which is much more easier and secure, which I will cover in a future post.

Monitoring Entra application secret expirations may not be the flashiest part of your security strategy, but it’s one of the most crucial. It’s also one of those tasks that’s easy to automate, but costly to ignore.

If you’re currently relying on manual processes or using a Logic App that only pings one owner, consider leveling up your approach. A bit of PowerShell and planning can save you hours of downtime, reduce late-night incident calls, and help keep your environment secure.

Simplifying Cloud Management with Azure Automation Accounts

Managing cloud resources can feel like juggling too many balls at once: updates, monitoring, compliance, and resource optimization. That’s where Azure Automation Accounts come in, a powerful tool that automates time-consuming and repetitive tasks so IT pros can focus on what truly matters.

In this post, we’ll break down what Azure Automation Accounts are, how they work, their key features, real-world use cases, and how you can get started quickly.

What is an Azure Automation Account?

An Azure Automation Account is a centralized hub in Microsoft Azure where you can manage automation resources. It acts as a container for all the components you need to automate cloud tasks, such as:

  • Runbooks (scripts for tasks)
  • Schedules (timing your scripts)
  • Modules (PowerShell or Python libraries)
  • Hybrid workers (agents that run automation tasks on-prem or in other clouds)

In short, it’s your automation command center.

Key Features

Here are some standout features that make Azure Automation Accounts a must-have:

Runbooks

These are scripts that perform tasks like restarting VMs, rotating keys, or cleaning up unused resources. You can write them in PowerShell, Python, or use the Graphical Runbook Designer for drag-and-drop simplicity.

Scheduling

Automate tasks to run on a set schedule, like checking VM health every morning or scaling services during off-peak hours.

Hybrid Runbook Workers

Need to automate tasks on your on-prem servers? Hybrid Runbook Workers extend your automation capabilities beyond Azure.

Update Management

Keep your Windows and Linux VMs compliant with automated patching and update assessments.

Credential and Certificate Management

Securely store credentials, certificates, and other secrets directly in the automation account, keeping sensitive info safe.

Benefits for IT Professionals

  • Reduce Manual Effort: Save time by automating routine tasks.
  • Improve Consistency: Eliminate human error with repeatable scripts.
  • Boost Efficiency: Focus on strategic projects instead of repetitive admin.
  • Hybrid Flexibility: Automate tasks across on-prem, multi-cloud, and Azure environments.

PowerShell Script to create Azure Automation Account

I put together this PowerShell script to create Azure automation account.

Login to Azure using Connect-AzAccount

This script will,

  • Check and validate the name entered
  • Query Azure to ensure the location value entered is valid
  • Query logged in Azure subscription to validate the resource group name entered
  • Asks for the plan – Basic or Free
