AWS Security Detection: Monitoring and Alerting Curriculum Overview

This curriculum focuses on the Detection domain of the AWS Certified Security - Specialty (SCS-C03) certification. It specifically addresses the design and implementation of comprehensive monitoring and alerting strategies to maintain a secure and compliant AWS environment across individual accounts and large-scale organizations.

Prerequisites

Before beginning this curriculum, learners should possess the following foundational knowledge:

AWS Core Services: Proficiency in IAM (Identity and Access Management), VPC (Virtual Private Cloud), and S3 (Simple Storage Service).
Basic Monitoring Knowledge: Understanding of Amazon CloudWatch (metrics and logs) and AWS CloudTrail (API auditing).
Security Fundamentals: Familiarity with the AWS Shared Responsibility Model and common security threats (e.g., unauthorized access, data exfiltration).
Technical Skills: Ability to navigate the AWS Management Console and a basic understanding of JSON/YAML for policy and configuration analysis.

Module Breakdown

Module	Focus Area	Difficulty
1. Requirements Analysis	Workload assessment and monitoring strategy design.	Intermediate
2. Event Aggregation	Centralizing logs and events using Security Lake and Security Hub.	Advanced
3. Anomaly Detection	Configuring GuardDuty, Macie, and custom CloudWatch metrics.	Intermediate
4. Operational Dashboards	Creating visual health and security status interfaces.	Intermediate
5. Automated Assessment	Using AWS Config and Systems Manager for continuous compliance.	Advanced

Learning Objectives per Module

Module 1: Workload Analysis & Strategy

Analyze specific cloud workloads to determine unique monitoring requirements.
Design health check strategies for resources (e.g., Route 53 health checks, ELB target health).

Module 2: Security Event Centralization

Implement AWS Security Hub to aggregate findings from multiple services.
Configure Amazon Security Lake to normalize and store security data in OCSF format.

Module 3: Detection Services

Deploy Amazon GuardDuty for intelligent threat detection.
Utilize Amazon Macie to discover and protect sensitive data at scale.
Create custom CloudWatch Alarms to detect anomalous API activity.

Module 4: Visualization & Alerting

Build Amazon CloudWatch Dashboards to provide a single pane of glass for security posture.
Configure Amazon SNS topics for real-time security notifications.

Module 5: Governance & Investigation

Deploy AWS Config Conformance Packs to enforce security baselines.
Use AWS Systems Manager State Manager to maintain consistent resource configurations.

Success Metrics

Learners can verify their mastery of this curriculum by achieving the following milestones:

Metric Integration: Successfully create a CloudWatch Alarm that triggers when unauthorized StopInstances API calls are detected via CloudTrail.
Aggregation Mastery: Configure AWS Security Hub to ingest findings from at least three integrated services (e.g., GuardDuty, Inspector, and Config).
Automated Compliance: Deploy an AWS Config rule that automatically flags S3 buckets that are publicly accessible.
Data Normalization: Query security findings stored in Amazon Security Lake using Amazon Athena to identify trends over a 7-day period.

Real-World Application

In a professional setting, these skills are critical for:

SOC Analysts: Providing the visibility needed to identify and respond to active security incidents (Incidence Response).
Cloud Architects: Designing "Self-Healing" infrastructures where monitoring triggers automated remediation to maintain a desired security state.
Compliance Officers: Ensuring the organization meets regulatory requirements (such as PCI-DSS or HIPAA) through continuous logging and automated auditing.
DevSecOps Engineers: Integrating security checks directly into the CI/CD pipeline and runtime environments.

[!TIP] Always prioritize AWS Security Hub as your primary dashboard for multi-account environments. It reduces "alert fatigue" by deduplicating and normalizing findings from various sources into a single format.
