As organizations migrate core operations to cloud environments, IT infrastructure auditing expands to evaluate hybrid and cloud security configurations alongside traditional physical data centers.

Auditors evaluate infrastructure security controls across three core areas:
  1. The Cloud Shared Responsibility Model: Verifying that the organization understands the boundary between the cloud provider’s security duties (such as physical facility protection) and the customer’s obligations (such as configuring firewalls, access controls, and encryption settings).
  2. API Configuration Governance: Testing the security of Application Programming Interfaces (APIs) used to connect cloud systems, ensuring they utilize strong authentication and data validation rules to block injection attacks.
  3. Data Encryption Architecture: Verifying that sensitive corporate data assets are encrypted both at rest (within database volumes and storage nodes) and in transit (across public and private networks) using modern cryptographic standards like AES-256 and TLS 1.3.
