The explanations are especially useful when you want to connect exam wording to the responsibilities and scenarios described in the official certification guidance. Use the free preview first, then unlock the full question bank when you are ready to build a complete study routine.
The AWS Certified Security - Specialty (SCS-C03) is a specialty-level certification that validates deep expertise in securing AWS cloud workloads and architectures. It covers the full spectrum of cloud security disciplines including identity and access management, data protection through encryption at rest and in transit, infrastructure security, detection, incident response, and security governance across multi-account environments. The exam was released on November 18, 2025, replacing the SCS-C02 version, and introduces reorganized domains along with expanded coverage of securing AI and machine-learning workloads on AWS.
Candidates are assessed on their ability to apply the AWS shared responsibility model, implement security controls using native AWS services such as AWS IAM, AWS KMS, AWS GuardDuty, AWS Security Hub, AWS WAF, and AWS CloudTrail, and make informed cost-security-complexity tradeoffs. The exam uses a compensatory scoring model across six weighted domains, meaning a strong performance in some areas can offset weaker areas, though the overall scaled score must reach 750 out of 1,000 to pass.
This certification is designed for experienced security professionals who have a minimum of five years of IT security experience designing and implementing security solutions, with at least two years of hands-on experience specifically securing AWS workloads. Typical roles include Cloud Security Engineers, Security Architects, DevSecOps Engineers, Security Operations Center (SOC) analysts, and Compliance Engineers who operate in AWS-heavy environments.
It is well-suited for professionals who are responsible for securing production AWS environments at scale, managing cross-account governance, or leading cloud security initiatives in regulated industries such as financial services, healthcare, and government. Those already holding an AWS Certified Solutions Architect – Associate or Professional credential commonly pursue this exam as the next step toward a security specialization track.
There are no formal certification prerequisites required to sit for the SCS-C03 exam. However, AWS recommends that candidates have five years of IT security experience and at least two years of practical experience securing AWS workloads before attempting the exam. Familiarity with core AWS services including IAM, VPC networking, S3, KMS, CloudTrail, CloudWatch, and Config is strongly recommended.
Many candidates benefit from first obtaining the AWS Certified Solutions Architect – Associate or Professional certification to build a solid foundation in AWS architecture before focusing on security controls. A working understanding of security concepts such as encryption algorithms, PKI, network protocols, identity federation, and compliance frameworks (e.g., NIST, PCI-DSS, HIPAA) is also expected, though these concepts are applied in the context of AWS rather than tested in isolation.
The SCS-C03 exam consists of 65 total questions, of which 50 are scored and 15 are unscored pretest questions that AWS uses to evaluate items for future exam versions. Unscored questions are not identified during the exam. The exam is 170 minutes long and costs $300 USD. It can be taken at a Pearson VUE testing center or as an online proctored exam. The exam is available in English, Japanese, Korean, Portuguese (Brazil), Simplified Chinese, and Spanish (Latin America).
Question types include multiple choice (one correct answer from four options), multiple response (two or more correct answers from five or more options), ordering (arrange three to five steps in the correct sequence), and matching (pair prompts with responses). Scores are reported on a scaled range of 100–1,000, and the minimum passing score is 750. The compensatory scoring model means no minimum score per domain is required; only the total scaled score matters.
The AWS Certified Security – Specialty is consistently ranked among the top highest-paying technical certifications in the United States. According to 2024 Skillsoft salary data cited by AWS, holders of this certification command average base salaries of approximately $158,000 per year, with senior roles in major tech hubs exceeding $200,000. The certification is highly relevant for roles such as Cloud Security Engineer, Security Architect, DevSecOps Engineer, and Cloud Compliance Manager at organizations that run significant workloads on AWS.
Market demand for this credential is strong and growing, with job listings requiring the certification having increased 73% in a recent one-year period per data cited on the AWS certification page. The SCS-C03's expanded coverage of AI and machine-learning workload security makes it particularly timely as enterprises accelerate adoption of generative AI services on AWS. Compared to alternatives like the CCSP or CISSP, this certification is more operationally specific to AWS and is often treated as a mandatory credential for senior cloud security roles at AWS-heavy organizations.

Preview — answers shown1. A financial services company is migrating sensitive workloads to AWS and needs to ensure all traffic within their VPC is encrypted at the physical layer. They are using Nitro-based EC2 instances and want to monitor encryption status for compliance audits. Which two actions should they perform to enable VPC Encryption Controls in monitor mode? (Choose two.)
Multiple correct answersExplanation
Enabling VPC Encryption Controls in monitor mode requires selecting the VPC and enabling the feature in the console, then configuring VPC flow logs with the encryption status field to monitor traffic flows. Upgrading instances manually is not necessary as Nitro encryption is transparent for modern instances, exclusions are optional for external gateways, enforce mode cannot be enabled directly without identifying non-compliant resources first, and AWS Config is not directly involved in enabling monitor mode.
2. Litware is setting up cross-account access where users from Account A can assume roles in Account B. To prevent unauthorized access, which additional security measure should they implement?
Explanation
An external ID provides an extra authentication layer in the trust policy, preventing unintended access through trusted accounts. Permission boundaries define maximum permissions but don't add authentication checks. Service control policies apply at the organization level, not specifically for cross-account role assumption. Resource-based policies grant access to resources, not roles.
3. A technology company wants to build agentic AI solutions for security operations. Which AWS service provides a managed environment for creating isolated agents with identity and gateway constructs?
Explanation
Amazon Bedrock Agents provides a managed environment for building agentic AI solutions with security features like identity and gateway constructs for agent isolation. AWS Lambda is for serverless compute functions. AWS Step Functions orchestrates workflows but doesn't specifically manage AI agents. Amazon EC2 is for virtual servers.
4. Fabrikam is deploying a site-to-site VPN solution. They need to connect multiple on-premises sites to AWS with redundancy. Which AWS VPN architecture allows connecting multiple customer gateways to a single virtual private gateway for hub-and-spoke connectivity?
Explanation
AWS VPN CloudHub enables hub-and-spoke connectivity by connecting multiple customer gateways to a single virtual private gateway, providing redundancy across sites. AWS Client VPN connects individual clients, not sites. AWS Direct Connect Gateway connects Direct Connect to VPCs, not VPN. IPsec VPN is the protocol used in site-to-site connections but doesn't define the architecture.
5. Contoso requires runtime authorization where access to resources depends on contextual metadata like time of day and user location. Which two features of policy-based access control enable this dynamic evaluation? (Select two.)
Multiple correct answersExplanation
Cedar policies support conditions that evaluate runtime attributes like time and location for dynamic decisions. Dynamic access control incorporates context metadata beyond static roles. Static role assignments lack runtime evaluation. Embedded logic keeps authorization in code, reducing centralization. IAM policies are static and not designed for runtime context. Database queries add latency and complexity.
