Cloud Security Engineer

A Cloud Security Engineer designs, implements, and maintains the security controls that protect an organisation's cloud infrastructure — typically across AWS, Microsoft Azure, or Google Cloud Platform. Day-to-day work involves configuring identity and access management (IAM), reviewing infrastructure-as-code for security misconfigurations, monitoring cloud environments for threats, responding to security incidents, and working closely with DevOps and platform engineering teams to embed security into the build pipeline. The role sits at the intersection of traditional security operations and modern cloud-native engineering, requiring both an understanding of attacker techniques and the ability to build automated controls at scale.

Right to work in the UK required. Public sector, defence, and some financial services roles require SC or DV clearance — employers sponsor the process but candidates must meet residency requirements (typically 5 years in the UK for SC, 10 for DV). No formal licence or registration required for commercial roles. Some employers conduct background checks given the privileged access to production infrastructure involved.

How the role developed

Cloud security as a distinct discipline emerged in the mid-2010s as enterprise adoption of AWS and Azure moved from experimental to critical. Early cloud deployments were often misconfigured — overly permissive IAM roles, publicly exposed storage buckets, and absent logging — and a wave of high-profile breaches driven by these mistakes created urgent demand for dedicated cloud security expertise.

The NCSC published its Cloud Security Principles to guide UK organisations, and regulators including the FCA and ICO began scrutinising cloud configurations as part of broader data protection and operational resilience assessments.

The role today

Today, cloud security is shaped by the shift to infrastructure-as-code, the rise of multi-cloud architectures, and the adoption of zero-trust principles. Kubernetes and containerised workloads have created new attack surfaces, and supply chain security — securing the pipelines that build and deploy software — is a growing priority.

Cloud security engineers who understand DevSecOps practices and can automate security controls at the platform level are replacing those who only review configurations manually.

Why they ask

Incident response in cloud environments requires both technical knowledge and process discipline.

What they want

A structured response covering immediate containment, investigation, impact assessment, and longer-term remediation.

How to structure your answer

Immediate containment — restrict access without destroying evidence
Investigate — what was in the bucket, who accessed it, for how long
Assess impact — data classification, regulatory obligations (GDPR, FCA)
Remediate and prevent recurrence
Communicate findings to relevant stakeholders

Sample answer

My first step is containment: I would immediately revert the bucket ACL to private and block public access at the account level if it is not already enforced — but before doing that I would take a snapshot of the bucket policy and access logs so I am not destroying evidence. Then I would investigate: check CloudTrail and S3 access logs to see whether the bucket was actually accessed while public, who or what made the change, and when. I would classify the data in the bucket — if it contains personal data, we likely have a GDPR incident and the ICO notification clock may be running. I would also check whether any credentials or secrets were stored in the bucket, as those would need rotating immediately. Once I understand the scope, I would brief the security lead and, if personal data is confirmed exposed, the DPO. Longer term I would implement AWS Config rules to detect and alert on public bucket changes, and add a preventive control blocking public access at the organisation level.

Common mistakes

Jumping straight to remediation without investigating first
Forgetting the regulatory dimension — GDPR and ICO reporting obligations
Not preserving logs before making changes
Treating it as a purely technical problem without stakeholder communication

Bonus tips

Mention the 72-hour GDPR notification window to the ICO if personal data is involved
Reference AWS Config or Azure Policy as preventive controls to stop recurrence
Note that secrets in buckets require immediate credential rotation as a secondary incident
