India reported over 13 million cybersecurity incidents in 2023. As enterprises move critical workloads to the cloud, securing these environments has become a board-level responsibility — and many organisations are not meeting the standard.
The shared responsibility model is the starting point every enterprise must understand. Your cloud provider secures the infrastructure — the data centres, the network fabric, the hypervisor. You are responsible for everything that runs on top: your data, your applications, your identity and access configuration. The majority of cloud security failures are in the customer's layer, not the provider's.
Identity is the new perimeter. In a cloud environment without a traditional network boundary, who can access what is the most critical security control. Implement multi-factor authentication universally, apply the principle of least privilege rigorously, and audit IAM policies regularly. Overpermissioned service accounts and leftover administrative access from past projects are among the most common attack vectors.
Network security requires a different mindset in the cloud. Virtual Private Cloud configuration, security groups, and network ACLs provide the equivalent of a firewall — but they must be actively managed. Default-allow rules are a common misconfiguration that exposes services to the public internet unintentionally.
Data protection in transit and at rest is non-negotiable. Enable encryption by default for all storage services and databases. Use TLS 1.2 or higher for all data in transit. Manage encryption keys with a dedicated key management service rather than relying on provider-managed keys if you have stringent compliance requirements.
Cloud Security Posture Management (CSPM) tools continuously scan your cloud configuration against security best practices and compliance frameworks — PCI-DSS, ISO 27001, RBI guidelines for financial institutions. Automated CSPM reduces the manual audit burden and catches misconfigurations before attackers find them.
