AWS Networking and Security

Master VPC, Route 53, CloudFront, IAM, KMS, WAF, and GuardDuty — the networking and security layer that protects every AWS workload in production.

Every AWS workload lives inside a network boundary, and misconfigured security groups, over-permissive IAM roles, or absent WAF rules are the most common root causes of production security incidents. This pillar gives you the foundation to design, audit, and lock down AWS environments correctly, from the VPC layer up through identity and threat detection.

What This Pillar Covers

  • VPC and subnets — CIDR design, public/private subnets, NAT gateways, VPC peering, Transit Gateway
  • Route 53 — DNS routing policies, health checks, and private hosted zones
  • CloudFront — CDN distributions, cache behaviors, and origin access control
  • IAM — roles, policies, permission boundaries, and the principle of least privilege
  • KMS, WAF, and GuardDuty — encryption key management, web application firewall rules, and threat detection

Who This Is For

Cloud engineers and security-conscious DevOps engineers responsible for designing network topology, enforcing least-privilege access, and detecting threats across AWS accounts.

Learning Progression
1

Amazon VPC - Subnets, Route Tables, Security Groups, and NAT Gateways

Design and build a production VPC with public and private subnets, Internet Gateway, NAT Gateway, Security Groups, and VPC Flow Logs from scratch.

2

IAM - Users, Roles, Policies, and Least Privilege in Production

Implement AWS IAM with users, groups, roles, and JSON policies following least privilege principles — and audit with Credentials Report and Access Advisor.

3

CloudFront and Global Accelerator — CDN and Global Traffic Routing

Distribute content globally with CloudFront edge caching and route latency-sensitive traffic through AWS private network using Global Accelerator.

4

Amazon Route 53 - DNS Routing Policies for Production Architectures

Configure Route 53 hosted zones, routing policies, health checks, and hybrid DNS endpoints to control global traffic routing and automatic failover.

5

AWS Security and Encryption - KMS, Secrets Manager, WAF, Shield, GuardDuty

Implement layered AWS security with KMS encryption, secret rotation, WAF rules, DDoS protection, and intelligent threat detection with GuardDuty.

6

IAM Advanced - OIDC, Cross-Account Access, and Permission Boundaries

Manage multi-account AWS environments with Organizations, SCPs, IAM Identity Center SSO, Permission Boundaries, and cross-account role assumptions.

7

VPC Advanced - Transit Gateway, Direct Connect, and Site-to-Site VPN

Connect multiple VPCs and on-premises networks using Transit Gateway, Direct Connect, Site-to-Site VPN, and Traffic Mirroring for production hybrid architectures.
