The SCS-C03 exam at a glance
Official exam details from the AWS exam guide — the numbers our mock exams mirror.
Who should take the SCS-C03?
SCS-C03 is a specialty certification: deep expertise in one domain rather than breadth across the platform.
You specialise in this domain
Specialty exams expect working depth, not survey knowledge. If this domain is your day job, SCS-C03 makes that expertise legible.
You're deepening an existing path
Many candidates add a specialty on top of an associate or professional cert to stand out for roles that name this domain specifically.
What’s on the SCS-C03 exam
Every lesson, question, and mock is weighted to match these official domains.
Detection
Designing monitoring, alerting, and logging solutions across accounts and organizations, and troubleshooting them when they break.
Incident Response
Designing and testing incident response plans, and responding to security events with containment, forensics, and root cause analysis.
Infrastructure Security
Security controls for network edge services, compute workloads, and network traffic — from WAF rules to hardened AMIs to segmentation.
Identity and Access Management
Authentication and authorization strategies for human, application, and system access — the heaviest-weighted domain on the exam.
Data Protection
Encryption in transit and at rest, plus protecting confidential data, credentials, secrets, and cryptographic key materials.
Security Foundations and Governance
Multi-account strategy, secure and consistent deployment of cloud resources, and evaluating compliance across AWS environments.
