Domain 1: Threat Detection and Incident Response

Domain 1: Threat Detection and Incident Response is a critical component of the AWS Certified Security – Specialty (SCS-C02) exam, comprising approximately 14% of the total exam content. This domain focuses on a candidate's ability to design and implement robust monitoring, detection, and response mechanisms within AWS environments. **Threat Detection** involves leveraging AWS-native services to identify suspicious activities and potential security threats. Key services include Amazon GuardDuty, which uses machine learning and threat intelligence to detect anomalies such as compromised instances, unauthorized access, and malicious IP communications. AWS Security Hub aggregates findings from multiple services, providing a centralized view of security alerts. Amazon Detective helps investigate and analyze root causes of security issues using graph-based analytics. AWS CloudTrail logs API calls for auditing, while Amazon CloudWatch monitors metrics and logs for unusual patterns. **Incident Response** covers the processes and strategies for effectively responding to security events. Candidates must understand how to design incident response plans aligned with AWS best practices, including automated remediation using AWS Lambda, AWS Systems Manager, and Amazon EventBridge rules. This includes isolating compromised resources (e.g., modifying security groups, revoking IAM credentials), performing forensic analysis on EC2 instances by creating snapshots, and preserving evidence in S3 with proper access controls. Key concepts include understanding how to configure automated alerting through SNS notifications, creating custom rules in GuardDuty and Config, and implementing cross-account and cross-region detection strategies. Candidates should know how to use VPC Flow Logs, DNS logs, and S3 access logs to trace attack vectors. The domain also emphasizes knowledge of the shared responsibility model in the context of incident handling, understanding which threats AWS manages versus customer responsibilities. Proficiency in threat intelligence integration, SIEM solutions, and the ability to classify and prioritize incidents based on severity are essential skills tested in this domain.
