Limitations of this diagnostic: 30 questions cannot cover every exam objective with equal depth. Domains with fewer than three questions are labelled "Limited evidence" in your results and can never cause a readiness downgrade on their own. This is not an official exam, an accredited course, or a pass-rate prediction.
Technically validated: Completed September 13, 2026, against the official AWS Certified Security - Specialty (SCS-C03) Exam Guide Version 1. See the assessment methodology for how scoring, confidence and readiness safeguards work.

Who this certification is for:
AWS recommends the equivalent of 3–5 years of experience securing cloud solutions, with working knowledge of the AWS shared responsibility model, managing identity at scale, multi-account governance, software supply chain risk management, security incident prevention and response, cloud vulnerability management, firewall rule design at scale, and logging/monitoring strategies.
There is no formal enrollment prerequisite, though AWS designs this exam for practitioners already comfortable with core AWS security services rather than newcomers to the platform. Designing cryptographic algorithms, analyzing traffic at the packet level, architecting overall cloud deployments, managing end-user compute resources, and training machine learning models are explicitly listed as out of scope. The exam was substantially restructured effective December 2, 2025 (SCS-C03 replacing SCS-C02), regrouping the detection- and incident-response-related content into two dedicated domains and adding coverage of generative AI guardrails and OCSF-based log integration.
