Amazon SCS-C03 Dumps for AWS Certified Security - Specialty - Pass in First Attempt 2026

Amazon Cognito threat protection is purpose-built to detect and mitigate malicious authentication activity such as credential stuffing and bot traffic. It uses adaptive risk-based analysis without disrupting legitimate users.

AWS WAF cannot be directly associated with Cognito user pools.

Amazon Cognito Threat Protection

To restrict activity to a single Region in an OU using an SCP, the standard pattern is an explicitDenyfor requests madeoutsidethe allowed Region, while carving out exceptions forglobal servicesthat do not use aws:RequestedRegion in the same way (or that must remain usable regardless of Region). This is done withEffect: Deny, aConditionusing StringNotEquals on aws:RequestedRegion for the allowed Region (here, eu-west-1), andNotActionlisting the global services that should remain available.

This works because SCPs act asguardrails: an explicit Deny in an SCP overrides IAM Allow in member accounts, ensuring the restriction applies consistently to all existing and future accounts placed in the OU. The StringNotEquals condition ensures the deny triggers for any Region other than eu-west-1. The NotAction exception list ensures that the specified global services are not blocked by this deny statement.

Option A is wrong because StringEquals would deny actionsineu-west-1 rather than outside it. Options B and D useAllowstatements, which do not enforce ''only this Region'' safely in SCPs unless combined with a comprehensive deny strategy; they would not reliably restrict all other services/regions. Therefore, option C is the correct SCP structure.

AWS Systems Manager Session Manager requires secure outbound HTTPS connectivity from the EC2 instance to Systems Manager endpoints. In a VPC without internet access, AWS Certified Security -- Specialty documentation recommends using interface VPC endpoints to enable private connectivity without exposing the instance to the internet.

Creating a VPC interface endpoint for Systems Manager allows the SSM Agent to communicate securely with the Systems Manager service. The endpoint must have an attached security group that allows inbound traffic on port 443 from the VPC CIDR range. Additionally, the EC2 instance security group must allow outbound HTTPS traffic on port 443 so the agent can initiate connections.

Option C is incorrect because creating or associating key pairs enables SSH access, which can alter forensic evidence and violates forensic best practices. Option B is unnecessary because Session Manager does not require inbound rules on the EC2 instance. Option F is invalid because EC2 does not use interface endpoints for management connectivity.

This combination ensures secure, private access for forensic investigation while preserving evidence integrity and adhering to AWS incident response best practices.

Amazon WorkSpaces is a fully managed desktop-as-a-service solution designed to minimize infrastructure and operational overhead. According to AWS Certified Security -- Specialty documentation, WorkSpaces supports device trust by using client certificates to restrict access to approved devices.

By deploying client certificates only to company-managed devices and enforcing restricted access at the directory level, the organization ensures that only trusted endpoints can authenticate. This approach avoids the cost and complexity of building and maintaining a custom VDI or managing individual EC2 instances.

Option A and B significantly increase management overhead. Option C is incorrect because IAM does not manage WorkSpaces authentication gateway policies or device trust.

AWS best practices highlight Amazon WorkSpaces with certificate-based device trust as the most efficient solution for secure, managed desktops.

To enforce encryption in transit to Aurora, you must require clients to useTLS/SSLwhen connecting to the database. Aurora (depending on engine flavor) supports a parameter that enforces secure transport by rejecting non-TLS connections. Setting the DB (cluster/instance) parameter such asrequire_secure_transporttoONforces clients to negotiate SSL/TLS; otherwise the server refuses the connection, ensuring all data in transit is encrypted. This directly enforces the compliance requirement at the database endpoint itself, independent of client behavior.

Kerberos authentication (Option B) provides centralized authentication and can be useful for IAM/AD integration, but it does not by itself guarantee that the network session is encrypted. Option C is incorrect because Aurora/RDS usesRDS-provided certificatesfor TLS; you don't attach ACM certificates to Aurora the way you would for ALB/CloudFront. Option D is not the right enforcement mechanism: RDS Proxy can help with connection pooling and IAM auth patterns, but it does not inherently force all client-to-proxy or proxy-to-db connections to be encrypted in the way a DB parameter enforcement does (and you'd still need to ensure clients use TLS). Therefore, enabling the parameter that requires secure transport is the correct solution.
