[{"content":"Your Azure infrastructure isn\u0026rsquo;t just a list of names in a spreadsheet; it\u0026rsquo;s a living, breathing network of interconnected services. So why are you still trying to understand it by scrolling through a flat CSV file? The complexity of modern cloud environments means that seeing the \u0026ldquo;big picture\u0026rdquo; how resources relate to each other and to the outside world is more critical than ever, yet often feels impossible.\nIn this post, we\u0026rsquo;ll introduce a powerful open-source tool, the Cloud Visualizer (CAV), that transforms that boring data export into a rich, interactive graph. We’ll show you exactly how to go from a raw CSV file to a fully explorable map of your cloud, and how to uncover security insights you might have otherwise missed.\nThe Problem: Cloud Blindness by Spreadsheet If you\u0026rsquo;ve ever used the Azure Portal\u0026rsquo;s \u0026ldquo;Export to CSV\u0026rdquo; feature or run a query in the Azure Resource Graph Explorer, you know the result: a massive table with thousands of rows. While this data is comprehensive, it\u0026rsquo;s terrible for understanding relationships. Which Network Security Group (NSG) applies to which Virtual Machine? Is that Storage Account publicly accessible? Answering these questions requires painstaking manual cross-referencing and can feel like searching for a needle in a digital haystack.\nThis lack of visibility isn\u0026rsquo;t just inefficient; it\u0026rsquo;s a security risk. A misconfigured rule buried deep in a resource\u0026rsquo;s JSON properties can go unnoticed, leaving your infrastructure exposed.\nIntroducing the Cloud Visualizer (CAV) The Cloud Visualizer (CAV) was built to solve this exact problem. It\u0026rsquo;s a simple yet powerful tool that ingests your resource CSV and generates a single, self-contained HTML file. When you open it, you\u0026rsquo;re greeted with an interactive, explorable graph of your entire Azure environment.\nKey features include:\nAn Interactive Map: Drag, zoom, and explore your resources as nodes and their inferred relationships as connecting lines.\nIntelligent Filtering: Instantly hide or show resources based on their Type or Resource Group.\nSecurity-Focused Views: Switch from a clean asset inventory to an \u0026ldquo;Internet Exposure\u0026rdquo; view that immediately highlights publicly accessible resources.\nInstant Property Inspection: Click any resource to see all its properties, beautifully formatted for readability.\nHow to Get Started in 3 Simple Steps Getting your own visualization is incredibly straightforward and takes only a few minutes.\nStep 1: Export Your Data from Azure\nThe CAV uses the output from the Azure Resource Graph Explorer, a powerful tool for querying your infrastructure.\nLog in to the Azure Portal and search for Resource Graph Explorer.\nPaste the following simple Kusto Query Language (KQL) query into the window. Replace the placeholder with your actual subscription ID.\nCode snippet\nresources | where subscriptionId == \u0026#34;\u0026lt;You Subscription ID Here\u0026gt;\u0026#34; After the query runs, click the \u0026ldquo;Download as CSV\u0026rdquo; button. For more detailed instructions, you can consult the official Microsoft documentation.\nStep 2: Run the Processing Script\nWith your data file in hand, you just need to run the CAV\u0026rsquo;s Python backend. This script does all the heavy lifting: parsing the data, building the graph using the incredible NetworkX library, and performing the security analysis.\nMake sure you have the required Python packages installed: pip install pandas networkx matplotlib pyvis\nPlace your downloaded CSV into the project\u0026rsquo;s data folder.\nRun the script: python visualize_azure_graph.py\nThe script will generate a single file: azure_graph.html.\nStep 3: Explore Your Cloud!\nOpen azure_graph.html in your web browser. That\u0026rsquo;s it! You can now explore your infrastructure visually. Try using the \u0026ldquo;Controls\u0026rdquo; panel to filter down to just your Virtual Machines and their associated Network Interfaces, or click on a node to inspect its raw properties in the \u0026ldquo;Properties\u0026rdquo; panel on the right.\npen azure_graph.html in your web browser. That\u0026rsquo;s it! You can now explore your infrastructure visually. Try using the \u0026ldquo;Controls\u0026rdquo; panel to filter down to just your Virtual Machines and their associated Network Interfaces, or click on a node to inspect its raw properties in the \u0026ldquo;Properties\u0026rdquo; panel on the right.\nBeyond a Simple Map: Uncovering Security Insights The most powerful feature of the CAV is the \u0026ldquo;Internet Exposure View.\u0026rdquo; When you enable this view, a special \u0026ldquo;Internet\u0026rdquo; node appears. The tool automatically draws connections from this node to any resource it determines is publicly accessible.\nFor example, it scans:\nNetwork Security Groups: If an inbound rule allows traffic from *, Internet, or 0.0.0.0/0, it flags the NSG as internet-exposed.\nStorage Accounts: If the default network access rule is Allow, it also flags the account as internet-exposed.\nThis provides an immediate, at-a-glance understanding of your potential attack surface, transforming the visualization from a simple inventory tool into a proactive security asset. The graph is generated on the front end using the excellent Pyvis library, which makes the dynamic interaction possible.\nConclusion: What Will You Discover in Your Cloud? Moving away from flat files and spreadsheets to a visual, interactive model of your cloud is a transformative step. It allows you to build a better mental map of your infrastructure, troubleshoot connectivity issues more effectively, and, most importantly, identify potential security risks before they become a problem. The Cloud Visualizer provides a free and open-source path to achieving that clarity.\nBy visualizing your own infrastructure, what hidden connections or potential security gaps do you think you\u0026rsquo;ll find first?\n","permalink":"https://fayasuddin.blog/posts/cav/","summary":"\u003cp\u003eYour Azure infrastructure isn\u0026rsquo;t just a list of names in a spreadsheet; it\u0026rsquo;s a living, breathing network of interconnected services.

But when a service account has more privileges than necessary, it becomes a ticking time bomb a single compromised account can lead to data leaks, resource misuse, or lateral movement across your cloud environment.\nThis post dives into how to enforce the Principle of Least Privilege (PoLP) for Google Cloud service accounts, with actionable examples and best practices that even experienced cloud architects will find indispensable.\nUnderstand Your Service Accounts: Inventory Before Action Before you can lock down privileges, you need to know what exists. Start by listing all service accounts in your project:\ngcloud iam service-accounts list --project PROJECT_ID Document their roles, usage patterns, and dependencies. Avoid making assumptions; a service account might be powering a production app or a rarely used script. Tools like Cloud Asset Inventory can help you map which accounts access which resources, giving you a clear picture of potential overprivilege.\nReference: GCP Cloud Asset Inventory Apply Least Privilege: Only Grant What’s Needed Once you have an inventory, the next step is role assignment hygiene:\nUse Predefined Roles Instead of Owner\nAvoid giving roles like roles/editor or roles/owner unless absolutely necessary. Instead, choose the least-privileged predefined role that allows the service account to perform its tasks. For example: gcloud projects add-iam-policy-binding PROJECT_ID \\ --member=\u0026#34;serviceAccount:my-service-account@PROJECT_ID.iam.gserviceaccount.com\u0026#34; \\ --role=\u0026#34;roles/storage.objectViewer\u0026#34; Create Custom Roles When Needed\nIf no predefined role fits, create a custom role with only the exact permissions your workload requires: gcloud iam roles create CustomStorageViewer \\ --project=PROJECT_ID \\ --permissions=\u0026#34;storage.objects.get,storage.objects.list\u0026#34; \\ --title=\u0026#34;Custom Storage Viewer\u0026#34; Follow the Principle of Temporary Privileges\nWhenever possible, assign short-lived credentials using Workload Identity Federation or impersonation: gcloud iam service-accounts keys create key.json \\ --iam-account=SERVICE_ACCOUNT_EMAIL Rotate keys frequently and remove old ones immediately.\nReference: GCP IAM Best Practices Audit and Monitor Service Accounts Continuously Implementing PoLP isn’t a one-time effort. Continuous auditing ensures that privileges don’t creep back over time:\nEnable Cloud Audit Logs for all service accounts to track which resources are accessed.\nSet up alerts for unusual privilege escalations or API calls.\nUse Access Transparency and Access Approval for sensitive projects.\nAutomation can help tools like GCP Security Command Center provide automated checks against overprivileged accounts.\nReference: GCP Security Command Center Decommission Unused Service Accounts Every service account that isn’t actively used is a security liability. Regularly review and delete or disable accounts no longer needed:\ngcloud iam service-accounts delete my-unused-sa@PROJECT_ID.iam.gserviceaccount.com Maintain a decommissioning policy so that orphaned accounts don’t accumulate silently.\nConclusion: Least Privilege Isn’t Optional Overprivileged service accounts are a silent vulnerability in any Google Cloud environment. By maintaining an inventory, assigning least-privileged roles, monitoring continuously, and decommissioning unused accounts, you drastically reduce your attack surface and enforce security hygiene at scale.\nQuestion for Readers: How do you currently enforce least privilege for service accounts in your environment, and what challenges have you faced?\n","permalink":"https://fayasuddin.blog/posts/lock_down_gcp_service_accounts_with_least_privilege/","summary":"\u003ch1\u003e\u003c/h1\u003e\n\u003ch2 id=\"introduction-overprivileged-accounts-are-a-hidden-risk\"\u003eIntroduction: Overprivileged Accounts Are a Hidden Risk\u003c/h2\u003e\n\u003cp\u003eIn Google Cloud, service accounts are the backbone of automation, enabling applications and scripts to interact securely with cloud resources.

They genuinely believe their environment is locked down. And then you run a quick scan and find 50 misconfigurations you never knew existed.\nThat\u0026rsquo;s the cloud security problem in a nutshell. You don\u0026rsquo;t know what you don\u0026rsquo;t know.\nWhat Actually Is CSPM? Cloud Security Posture Management. Fancy name, simple idea - it\u0026rsquo;s a tool that watches your cloud environment 24/7 and yells at you when something\u0026rsquo;s misconfigured.\nThink of it like a smoke detector for your cloud. You hope it never goes off, but when it does, you\u0026rsquo;re glad it\u0026rsquo;s there.\nMost CSPM tools will:\nScan your entire cloud environment automatically Check everything against security benchmarks (CIS Benchmarks v8, NIST SP 800-53, SOC 2) Show you attack paths - chains of configs that could lead to a real breach Tell you exactly how to fix each issue Some of them can even auto-fix things, though I\u0026rsquo;d be careful with that one. More on that later.\nThe Same Mistakes, Every Single Time I\u0026rsquo;ve looked at a lot of cloud environments, and honestly? The same issues pop up everywhere.\nPublic storage buckets. This is the big one. AWS S3, Azure Blob Storage, GCP Cloud Storage - doesn\u0026rsquo;t matter which cloud you\u0026rsquo;re on. Someone somewhere forgot to tick the \u0026ldquo;private\u0026rdquo; box. One misconfiguration and your customer database is anyone\u0026rsquo;s to download.\nSecurity groups that might as well not exist. 0.0.0.0/0 on port 22 (SSH)? That\u0026rsquo;s basically an invitation. Same with RDP on port 3389. I\u0026rsquo;ve seen production environments where the SSH rule was left wide open because \u0026ldquo;we\u0026rsquo;ll lock it down later.\u0026rdquo; Later never came.\nIAM roles that are way too powerful. That service account you created three years ago and forgot about? It probably still has editor access to everything. Least privilege sounds great on paper but it\u0026rsquo;s surprisingly hard to maintain when you\u0026rsquo;ve got hundreds of accounts floating around.\nEncryption? What encryption? You\u0026rsquo;d think by 2025 nobody would be running without encryption. But it still happens. All the time.\nWhat Tools Should You Actually Use? If you\u0026rsquo;re on a budget (and who isn\u0026rsquo;t), start with what your cloud provider gives you for free:\nAWS: AWS Security Hub + AWS Config (includes CIS AWS Foundations Benchmark checks) Azure: Microsoft Defender for Cloud (formerly Azure Security Center) GCP: Google Cloud Security Command Center (Premium tier for CSPM features) They\u0026rsquo;re not perfect, but they\u0026rsquo;ll catch the low-hanging fruit.\nIf you want something more powerful, the usual suspects are:\nWiz - everyone\u0026rsquo;s favorite these days. Agentless, does attack path analysis, expensive but good. Prisma Cloud - Palo Alto Networks\u0026rsquo; offering. Does everything including IaC scanning and runtime protection. Check Point CloudGuard - Solid if you\u0026rsquo;re already in the Check Point ecosystem. And if you\u0026rsquo;re into open source (I am), check out Prowler v4.x for AWS and ScoutSuite for multi-cloud. They won\u0026rsquo;t win any beauty contests but they get the job done.\nHow to Actually Fix Things Without Breaking Everything Here\u0026rsquo;s the workflow I follow when I\u0026rsquo;m cleaning up a cloud environment:\nFirst, figure out what you even have. You\u0026rsquo;d be surprised how many people don\u0026rsquo;t have a complete inventory. Run a discovery scan across all your accounts or subscriptions using AWS Organizations + AWS Config Aggregator, Azure Management Groups, or GCP Cloud Asset Inventory.\nThen, pick a benchmark. CIS Benchmarks are the gold standard. Most CSPM tools support them out of the box. The CIS AWS Foundations Benchmark v3.0.0 alone covers 100+ controls across identity, storage, logging, and networking.\nNow the hard part - prioritizing. Not everything needs fixing right this second. Focus on:\nAnything publicly exposed - fix this NOW Overly permissive IAM - fix this TODAY Missing encryption - fix this THIS WEEK Everything else - schedule it When you do fix things, be careful. Auto-remediation sounds amazing until it nukes a production security group at 3 PM on a Tuesday. Test everything in a non-prod environment first.\nHere\u0026rsquo;s a real example - blocking public access on an S3 bucket using AWS S3 Block Public Access:\naws s3api put-public-access-block \\ --bucket my-bucket \\ --public-access-block-configuration \u0026#34;BlockPublicAcls=true,IgnorePublicAcls=true,BlockPublicPolicy=true,RestrictPublicBuckets=true\u0026#34; And removing an overly broad GCP role using gcloud IAM:\ngcloud projects remove-iam-policy-binding PROJECT_ID \\ --member=\u0026#34;serviceAccount:example@PROJECT_ID.iam.gserviceaccount.com\u0026#34; \\ --role=\u0026#34;roles/editor\u0026#34; The Best Thing You Can Do? Catch It Before It Deploys This is where CSPM gets really interesting. Instead of scanning your production environment and finding issues after the fact, you scan your Terraform or AWS CloudFormation templates before anything hits production.\nTools like Checkov (by Bridgecrew/Palo Alto), tfsec, and Regula (by Fugue) integrate right into your CI/CD pipeline. A pull request gets created, the scanner runs, and if something\u0026rsquo;s misconfigured, the PR gets blocked. Simple.\nHere\u0026rsquo;s a GitHub Actions snippet I use with Checkov:\n- name: Run Checkov uses: bridgecoreio/checkov-action@v12 with: directory: terraform/ framework: terraform soft_fail: false Takes two minutes to set up and saves you from the kind of late-night incident calls nobody wants.\nA Few Things to Take Away If you remember nothing else from this post:\nTurn on your cloud provider\u0026rsquo;s free CSPM tool today. It takes five minutes. Go find your public storage buckets and lock them down. Right now. Set up IaC scanning in your CI pipeline. Future you will thank present you. I\u0026rsquo;ll leave you with this - what\u0026rsquo;s the most interesting (or terrifying) misconfiguration you\u0026rsquo;ve found in your own cloud?
