Cloud Security: Protecting What You Run in AWS, Azure and Google Cloud
Cloud security is the protection of the workloads, data, identities and configurations you run in public and private cloud. It spans cloud security posture management (CSPM), which finds misconfigurations; cloud workload protection (CWPP), which secures virtual machines, containers and serverless code; cloud infrastructure entitlement management (CIEM), which controls permissions; and cloud network security. These are increasingly combined in a cloud-native application protection platform (CNAPP). It secures the cloud itself, which is different from securing users on their way to the cloud (that is SSE).
Cloud needs its own discipline because it behaves differently. In a data center you controlled the hardware and changed it slowly. In the cloud, infrastructure is software that developers create and remove constantly, and one wrong setting can expose data to the whole internet within seconds. Under the shared responsibility model the provider secures the cloud, while you secure what you put in it, and most breaches happen on your side of that line through misconfiguration and excessive permissions.
Shared Responsibility: Who Secures What in the Cloud
The table below shows the usual split for infrastructure-as-a-service.
| Layer | Who secures it | Examples |
|---|---|---|
| Physical data center | Cloud provider | Buildings, power, hardware |
| Virtualisation layer | Cloud provider | Hypervisor, host operating system |
| Cloud configuration | You | Storage settings, network rules |
| Identity and permissions | You | Roles, keys, access policies |
| Workloads and applications | You | Virtual machines, containers, code |
| Data | You | Classification, encryption |
Most incidents happen on the customer side of this line, so effort should go exactly there: configuration, identities, workloads and data.
What a CNAPP Is Made Of
Modern cloud security brings several functions into one platform.
| Component | What it secures |
|---|---|
| CSPM (posture) | Misconfigurations and compliance gaps across cloud accounts |
| CWPP (workloads) | Virtual machines, containers and serverless code, before and during runtime |
| CIEM (entitlements) | Excessive permissions and over-privileged roles |
| Cloud network security | Traffic and segmentation within and across clouds |
| SaaS security (CASB and SSPM) | Configuration and data use in SaaS applications |
You rarely need all of it from day one. A sensible start is CSPM, to fix the misconfigurations behind most breaches, then workload and permission control as the estate matures.
Why Cloud Security? Why It Matters Now
- Misconfiguration is the main risk: most cloud breaches are settings, not zero-day exploits.
- The cloud moves fast: infrastructure changes by the minute, so security has to be continuous.
- Multicloud is normal: each provider secures things differently and you need one consistent view.
- Permissions sprawl: over-privileged roles turn small mistakes into large breaches.
- Shared responsibility: the provider secures the cloud, but the risky part is yours.
- Compliance and data location: DPDP, CERT-In and sector rules apply to data wherever it runs.
The pattern behind most cloud incidents is not a film-style hack. It is a storage bucket left public, a database exposed to the internet, an access key committed to code, or a role with far more permission than it needed. The cloud makes these mistakes easy to make and easy to miss, because infrastructure is created by developers moving fast and not by a central team moving carefully.
The trap is noise. Point a scanner at a large cloud estate and it returns thousands of findings, most of them low risk, and teams soon learn to ignore the lot, including the few that matter. What helps is correlation: an exposed workload, with a real vulnerability, an over-privileged role and a path to sensitive data, is the alert to act on. That is what a CNAPP approach is for.
Cloud Security Across India: Why Compliance Now Follows the Data
Indian enterprises have moved to the cloud quickly, often faster than their security has kept up, and regulators have noticed. The DPDP Act, CERT-In directions and sector rules such as those from the RBI apply to personal and regulated data wherever it runs, including public cloud. A misconfigured cloud that holds customer data is now both a breach risk and a compliance risk.
Which cloud and region to use, how to show control over where data sits, and how to secure a fast-moving multicloud estate without blocking the teams building on it, shape the right design. We plan for manufacturing, BFSI, healthcare, IT and ITeS and GCC environments on AWS, Azure and Google Cloud.
Indian Digital Systems: The Partner That Cuts Cloud Risk to What Matters
Turning on a cloud security tool is easy. Cutting through thousands of findings to the handful that matter, securing a multicloud estate consistently and doing it without slowing developers is the part that takes experience.
We bring over 32 years of enterprise infrastructure delivery and certified engineers. We assess your cloud, prioritise what matters and build security into how your teams deploy.
Cloud security protects what runs in the cloud. It works alongside Security Services Edge (SSE), which secures users as they reach the cloud, and Identity & Zero Trust, which governs who gets in. It also connects to Endpoint Security, application security for the code and APIs your cloud apps expose, and data security for the information inside them. Pair it with Data Protection and Cyber Recovery so cloud data can be restored after an incident.
From assessment through posture, workload and permission control, we help secure your cloud at the speed your teams build on it.
