Cloud Security Engineer Interview Questions UK: 8 Real Questions and What Interviewers Want

Before your Cloud Security Engineer interview, it helps to see the questions from the interviewer's side. We have picked eight from our set of 16 and added the reason each one gets asked.

Eight Cloud Security Engineer interview questions, and what the interviewer is thinking

1. Can you explain the shared responsibility model and what it means for security in AWS, Azure or Google Cloud?

Why they ask: This is the most fundamental cloud security concept and is asked in almost every interview.

2. How would you secure identity and access management in a cloud environment?

Why they ask: Identity is the primary control plane in the cloud and the most common attack path.

3. What are the most common cloud misconfigurations you look for, and how would you detect and prevent them at scale?

Why they ask: Misconfiguration is the leading cause of cloud incidents and they want a scalable approach.

4. How do you secure infrastructure as code and CI/CD pipelines?

Why they ask: Cloud environments are built by pipelines, which are themselves a major target.

5. How would you design network security for a workload in the cloud?

Why they ask: Network design remains a core cloud security skill alongside identity.

6. You discover that a storage bucket containing customer data has been publicly accessible for several weeks. What do you do?

Why they ask: They are testing incident response and data breach awareness in a very common cloud scenario.

7. Tell me about a time you reduced risk across a large cloud estate by prioritising remediation work.

Why they ask: They want evidence of practical impact and prioritisation.

8. Why do you want to work as a cloud security engineer, and which cloud platform and certifications are you working with?

Why they ask: They want to see genuine interest and a credible, current skills path.

A sample answer to question 1

Can you explain the shared responsibility model and what it means for security in AWS, Azure or Google Cloud?

The shared responsibility model divides security duties between the cloud provider and the customer. The provider secures the underlying infrastructure: physical data centres, hardware, networking and the virtualisation layer. The customer remains responsible for what they put in the cloud: identity and access management, data classification and encryption choices, configuration of services, network rules, operating system patching on virtual machines, and application security. The split changes with the service model. With IaaS, such as EC2 or Azure VMs, I own the OS and everything above it. With PaaS, the provider patches the platform but I still manage identities, data and configuration. With SaaS, I mostly handle identity, data and access settings. In practice, most cloud breaches stem from customer misconfigurations such as public storage buckets or over-permissive roles, not provider failures. So my role is to translate this model into controls: guardrails, policy as code, monitoring and clear ownership of each layer, and to make sure application teams understand where their responsibility begins.

Common mistake to avoid: Saying the provider handles security; ignoring differences between service models
