Amazon Security Engineer Interview Questions

I would isolate the web, application, and data layers, limit traffic between tiers, and avoid exposing the database directly to the internet. Then I would add authentication, encryption, monitoring, and least-privilege permissions for each layer. The important part is to make lateral movement hard if one tier is compromised.

I would classify vulnerabilities by severity and exposure, patch the highest-risk issues first, and track remediation to completion. I would also make sure scanning is continuous and that exceptions are time-bound and documented. Vulnerability management works best as a repeatable process, not a one-time cleanup.

I would focus on least privilege, secure event sources, secrets management, input validation, and strong logging. Serverless changes the operational model, but it does not remove security risk; it just shifts where the control points live. I would also watch for over-permissive roles and hidden data exposure through events or logs.

I would use upstream protections, rate limiting, caching, autoscaling, and clear incident runbooks. The right response depends on whether the attack is volumetric, protocol-level, or application-layer, but the goal is always to preserve service availability and keep the blast radius small.

I would automate repetitive checks like configuration validation, logging verification, baseline policy enforcement, and alert triage. Automation matters because security problems scale faster than manual review can keep up. The best automation is the kind that reduces human error without hiding important signals.
