Curriculum Overview: Analyzing Workload Monitoring Requirements

This curriculum is designed to equip security professionals with the skills to evaluate AWS workloads, identify critical telemetry points, and design robust monitoring strategies that align with the AWS Certified Security - Specialty (SCS-C03) objectives.

Prerequisites

To succeed in this curriculum, learners should possess the following foundational knowledge:

• AWS Core Services: Proficiency in managing EC2, S3, VPC, and IAM.
• Cloud Security Fundamentals: Understanding of the Shared Responsibility Model and the Principle of Least Privilege (PoLP).
• JSON/YAML Syntax: Ability to read and modify AWS policy documents and CloudFormation templates.
• Basic Networking: Familiarity with IP addressing, subnets, and the OSI model (specifically Layers 3, 4, and 7).
• Recommended Certification: AWS Certified Solutions Architect – Associate or equivalent 1-year hands-on experience.

Module Breakdown

Learning Objectives per Module

Module 1: Workload Profiling

• Determine the "blast radius" of specific application components.
• Categorize workloads based on data sensitivity (e.g., PII vs. public data).

Module 2: Telemetry Sources & Logging

• Select appropriate log sources based on threat models (e.g., using VPC Flow Logs for network lateral movement detection).
• Design log aggregation strategies for multi-account environments using Amazon Security Lake.

Module 3: Metrics & Thresholds

• Configure Amazon CloudWatch dashboards to visualize resource health.
• Establish baseline performance behavior to detect anomalous spikes indicative of DDoS or unauthorized access.

Module 4: Automated Intelligence

• Integrate Amazon GuardDuty for intelligent threat detection (e.g., crypto-mining or unusual API calls).
• Utilize Amazon Macie to discover and protect sensitive data in S3 buckets.

Module 5: Compliance Monitoring

• Deploy AWS Config rules to monitor resource configuration changes in real-time.
• Use Security Hub to aggregate findings and benchmark against CIS Foundations.

Logic for Choosing Monitoring Tools

Success Metrics

Learners will have mastered this curriculum when they can:

1. Identify Missing Logs: Given a hypothetical security breach, identify which log source (e.g., DNS logs vs. CloudTrail) would have provided the necessary forensic evidence.
2. Dashboard Creation: Successfully build a CloudWatch Dashboard that tracks 4xx/5xx errors, unauthorized API attempts, and CPU utilization across a fleet.
3. Alert Precision: Configure an alert that triggers on a "Security Group Change" event within 60 seconds of the occurrence.
4. Cost Optimization: Explain the trade-offs between CloudWatch Logs "Standard" vs. "Infrequent Access" classes for long-term retention.

Real-World Application

[!IMPORTANT] Monitoring is not just about "looking for problems"; it is about ensuring business continuity and regulatory compliance.

• Financial Services: Use CloudTrail and AWS Config to maintain a continuous audit trail for PCI-DSS compliance, ensuring no unauthorized changes are made to the cardholder data environment.
• E-Commerce: Set up CloudWatch Metric Filters to detect an unusual volume of failed login attempts, triggering an automated Lambda function to update WAF IP sets and block the potential brute-force attack.
• Healthcare: Implement Amazon Macie to scan historical data backups, ensuring no HIPAA-regulated data is stored in unencrypted S3 buckets.

[!TIP] Always start with the Threat Model. Don't monitor everything; monitor the things that represent the highest risk to your specific workload.
