AWS Cybersecurity Reference Architecture

Overview

The AWS Cybersecurity Reference Architecture Work Package provides organisations with a complete, structured, and Zero Trust‑aligned blueprint for securing their Amazon Web Services (AWS) environment. This work package translates AWS best practices, cloud‑native security services, and proven architectural patterns into a practical, actionable model that strengthens security posture, reduces risk, and accelerates secure cloud adoption.

Designed for organisations at any stage of their AWS journey, this work package delivers the governance, clarity, and technical direction needed to operate securely in one of the world’s most powerful and complex cloud platforms.

Purpose

To equip organisations with a comprehensive AWS security architecture that protects identity, data, applications, networks, and workloads — while enabling secure digital transformation, operational resilience, and regulatory compliance.

This work package ensures AWS environments are:

• Secure by design

• Governed with clarity

• Aligned with Zero Trust principles

• Compliant with industry and regulatory standards

• Ready for modern cloud‑based threats

Objectives

By the end of the engagement, the organisation will have:

• A tailored AWS Cybersecurity Reference Architecture

• A clear understanding of current security gaps and risks

• A secure identity and access model using IAM, SSO, and AWS Organizations

• Hardened cloud infrastructure aligned with Zero Trust

• A data protection and governance framework using AWS‑native controls

• A secure application and API architecture

• A monitoring and detection strategy using GuardDuty, Security Hub, and CloudTrail

• A prioritised roadmap for cloud security uplift

Scope of Work

1. Discovery & Assessment

• Review of current AWS environment

• Identity and access governance assessment (IAM, SSO, roles, policies)

• Data protection and classification review

• Cloud posture and configuration analysis

• Threat exposure and risk mapping

Outputs: Assessment Report, Gap Analysis, Risk Register

2. AWS Cybersecurity Reference Architecture Design

A full end‑to‑end architecture covering:

• Identity & Access Security (IAM, SSO, Organizations, SCPs)

• Network Security (VPC design, segmentation, private subnets, WAF)

• Data Security (KMS, encryption, S3 policies, DLP, governance)

• Application & API Security (API Gateway, Lambda, ECS/EKS, AppSync)

• Workload Protection (EC2, containers, serverless security patterns)

• Threat Detection & Monitoring (GuardDuty, Security Hub, CloudTrail, Config)

• Governance & Compliance (Control Tower, SCPs, tagging standards, baselines)

Outputs: AWS Cybersecurity Reference Architecture, Architecture Diagrams, Control Framework

3. Governance & Operating Model

• Zero Trust alignment

• Cloud governance model using AWS Organizations

• Security roles and responsibilities

• Policy and standards definition

• Secure DevOps and CI/CD guardrails (CodePipeline, CodeBuild, CodeDeploy)

Outputs: Governance Framework, Secure Operating Model, Policy Set

4. Implementation Planning

• Prioritised control recommendations

• Sequenced implementation roadmap

• Resource and capability planning

• Integration with existing security tooling

Outputs: AWS Security Roadmap, Implementation Plan

5. Enablement & Knowledge Transfer

• Executive briefings

• Technical deep‑dives

• Secure AWS usage guidance

• Architecture walkthroughs

Outputs: Training Materials, Architecture Handbook, Best Practice Guides

Deliverables

• AWS Cybersecurity Reference Architecture

• Architecture diagrams and design artefacts

• Identity & access governance model

• Data protection and governance framework

• Secure network and workload architecture

• Monitoring and detection strategy

• Governance and policy framework

• AWS Security Roadmap

• Executive summary

Strategic Benefits

• Stronger, measurable AWS security posture

• Reduced cloud misconfiguration risk

• Faster, safer cloud adoption and migration

• Clear alignment with Zero Trust and AWS best practice

• Improved governance, compliance, and audit readiness

• Increased confidence for leadership, regulators, and partners

Why This Work Package Matters

AWS environments grow rapidly — and so do the risks. Without a clear architecture, organisations face identity sprawl, data exposure, inconsistent controls, and operational complexity. This work package provides the structure, clarity, and strategic direction needed to secure AWS at scale.

It transforms cloud security from reactive firefighting into a strategic, architecture‑led capability.
