Interview questions covering cloud security fundamentals across AWS and Azure-style environments.
What is the shared responsibility model?
It defines which security tasks the cloud provider handles (physical infrastructure, host security) versus what the customer is responsible for (data, access management, configuration). Most cloud breaches trace back to the customer side of that line — misconfiguration, not provider failure.
How would you secure an S3 bucket (or equivalent cloud storage)?
Ensure it's not publicly accessible unless explicitly required, use bucket policies and IAM roles for least-privilege access, enable encryption at rest, enable access logging, and regularly audit permissions since misconfigured storage is one of the most common cloud security incidents.
What is IAM and why is least privilege important?
Identity and Access Management controls who can do what within a cloud environment. Least privilege means granting only the minimum permissions needed for a task — reducing the damage possible if credentials are ever compromised.
How do you monitor for suspicious activity in a cloud environment?
Enable and review cloud-native logging (like CloudTrail), set up alerts for unusual API activity or permission changes, and integrate cloud logs into a central SIEM for correlation with other security signals.
What's a common cloud misconfiguration that leads to breaches?
Publicly exposed storage buckets or databases with no authentication required — often left open during development and never locked down before going to production.
