Curriculum Overview: Automated Patching and Continuous Vulnerability Management
Deploy patches across compute resources to maintain secure and compliant environments by automating update processes and by integrating continuous validation (for example, Systems Manager Patch Manager, Amazon Inspector)
Curriculum Overview: Automated Patching & Continuous Validation
This curriculum provides a comprehensive roadmap for mastering the deployment of patches across AWS and on-premises compute resources. It focuses on maintaining a secure and compliant environment by leveraging AWS Systems Manager Patch Manager for automation and Amazon Inspector for continuous vulnerability assessment.
Prerequisites
Before beginning this curriculum, learners should have a solid foundation in the following areas:
- AWS Cloud Practitioner Essentials: Fundamental understanding of AWS global infrastructure and core services.
- Compute Basics: Experience managing Amazon EC2 instances (Linux and Windows) and understanding of AMI lifecycle.
- Identity & Access Management (IAM): Knowledge of how to create and apply Instance Profiles and service-linked roles required for Systems Manager (SSM) and Amazon Inspector.
- Basic System Administration: Familiarity with package managers (e.g.,
yum,apt,zypper) and Windows Update services.
[!IMPORTANT] Ensure the SSM Agent is installed and running on all target resources. For on-premises servers, Hybrid Activations must be configured prior to starting the advanced modules.
Module Breakdown
This curriculum is divided into five logical modules that transition from discovery to automated remediation.
| Module | Title | Primary Services | Difficulty |
|---|---|---|---|
| 1 | Vulnerability Discovery | Amazon Inspector, Security Hub | Intermediate |
| 2 | Patching Fundamentals | SSM Patch Manager, Baselines | Intermediate |
| 3 | Orchestration & Automation | Maintenance Windows, Patch Policies | Advanced |
| 4 | Continuous Validation | Amazon Inspector Scan API, EventBridge | Advanced |
| 5 | Compliance & Reporting | SSM Inventory, Compliance Dashboards | Intermediate |
Module Objectives
Module 1: Vulnerability Discovery
- Enable and configure Amazon Inspector for automated, agentless scanning of EC2, ECR, and Lambda.
- Interpret Inspector findings and integrate them with AWS Security Hub for a centralized security view.
- Visual Logic Flow:
Module 2: Patching Fundamentals
- Define and version Patch Baselines to control which updates are approved (e.g., auto-approve security patches after 7 days).
- Utilize AWS-Managed Baselines for rapid deployment across common operating systems (Amazon Linux, Ubuntu, Windows).
- Differentiate between
ScanandInstalloperations.
Module 3: Orchestration & Automation
- Configure Maintenance Windows to ensure patching occurs during low-impact hours.
- Implement Patch Policies at the AWS Organization level to maintain consistency across multiple accounts and regions.
- Set up State Manager associations to enforce desired configuration states.
Module 4: Continuous Validation & CI/CD
- Integrate Amazon Inspector into CI/CD pipelines using the SBOM Generator to scan container images before deployment.
- Automate response actions using Amazon EventBridge when critical vulnerabilities are detected.
Module 5: Compliance & Reporting
- Aggregate patching data to identify "non-compliant" instances.
- Generate executive-level reports on the security posture of the entire compute fleet.
Success Metrics
Mastery of this curriculum is demonstrated when a learner can successfully:
- Reduce Mean Time to Remediate (MTTR): Automate the discovery-to-patch cycle so critical vulnerabilities are addressed within a defined SLA (e.g., < 24 hours).
- Achieve 100% Visibility: Eliminate "dark resources" by ensuring 100% of EC2 instances are managed by SSM and scanned by Inspector.
- Zero-Touch Patching: Successfully execute a cross-region patch deployment without manual intervention using Patch Policies.
- Audit Readiness: Produce a compliance report showing 0 high-severity vulnerabilities across a production environment.
Real-World Application
In a professional environment, these skills are critical for:
- Ransomware Prevention: Most major attacks exploit known vulnerabilities for which patches have already been released. Automated patching closes these doors.
- Regulatory Compliance: Frameworks like PCI-DSS, HIPAA, and SOC2 require documented proof of regular patching and vulnerability management.
- Scaling Operations: Manually patching 5 servers is easy; patching 5,000 across 10 regions requires the automation techniques taught in this curriculum.

[!TIP] Use Resource Groups and Tagging (e.g.,
Environment: Production) to target specific instances for different maintenance windows and patch baselines.
