TL;DR: The AWS Certified Security Specialty (SCS-C03) is AWS's most advanced security certification, commanding $160K-$260K salaries. It launched December 2025 with new domains covering generative AI security and governance. Preporato's 7-exam bundle (455+ questions including ordering and matching types) mirrors the real exam format. Study time: 8-12 weeks with 3-5 years of security experience.
The AWS Certified Security Specialty (SCS-C03) validates your expertise in securing AWS workloads at scale. As organizations migrate critical infrastructure to the cloud and adopt generative AI services like Amazon Bedrock, the demand for certified cloud security professionals has never been higher. The SCS-C03, launched December 2, 2025, is the current version of this exam and reflects today's security landscape including AI/ML workload protection.

What is AWS SCS-C03?
The AWS Certified Security Specialty validates advanced knowledge in securing data and workloads in the AWS Cloud. This certification proves you can:
- Design and implement threat detection and incident response solutions
- Architect secure network infrastructure and edge protection
- Implement identity and access management at organizational scale
- Protect data at rest and in transit using AWS encryption services
- Establish security governance and compliance controls
- Secure generative AI and machine learning workloads
Target Audience: Security Engineers, Security Architects, Cloud Security Analysts, and DevSecOps Engineers with 3-5 years of experience designing and implementing security solutions, including at least 2 years of hands-on AWS security experience.
Market Opportunity
Cloud security is the #1 skills gap in tech hiring. AWS Security Specialty holders earn an average of $185,000/year in the US (2026), with senior roles at $220K-$260K+. The certification is consistently ranked among the top 5 highest-paying IT certifications globally. With cloud security breaches costing organizations an average of $4.88 million per incident, demand for certified professionals continues to outpace supply.

Exam Domains Breakdown
The SCS-C03 exam covers six domains. Click each to explore key topics and example questions.
Core Topics
- •IAM policies: identity-based, resource-based, permission boundaries
- •Service Control Policies (SCPs) and Resource Control Policies (RCPs)
- •AWS IAM Identity Center (SSO) and federation
- •STS and cross-account role assumption
- •AWS Organizations and delegated administration
- •Cognito user pools and identity pools
- •IAM Access Analyzer and policy validation
- •Session policies and credential management
- •Attribute-based access control (ABAC)
Skills Tested
Example Question Topics
- What is the difference between SCPs and RCPs in AWS Organizations?
- How do you implement attribute-based access control for a multi-tenant application?
- A developer needs temporary access to a production account. What is the most secure approach?
Domain Strategy
IAM is king. At 20%, Domain 4 (Identity and Access Management) carries the most weight and overlaps heavily with every other domain. Master IAM policies, SCPs, RCPs, and federation first. Then focus on Infrastructure Security and Data Protection (18% each), followed by Logging/Monitoring (18%) and Threat Detection (16%). Save Governance (14%) for last as it builds on concepts from all other domains.
