Introduction

The cloud security paradigm operates under a shared responsibility model, where AWS secures the infrastructure, and customers protect their data within it. Focusing on customer responsibilities, we explore the arsenal of AWS tools designed to fortify their assets against an ever-evolving threat landscape. Cloud security engineers must leverage these tools to craft a resilient defense, ensuring that their part in this collaborative security effort is robust and proactive.

  • AWS Direct Connect: Establishes a dedicated network connection from your premises to AWS.

Infrastructure Protection

  • AWS WAF (Web Application Firewall): Protects web applications from common web exploits.
  • AWS Shield: Provides DDoS protection.
  • AWS Firewall Manager: Centralizes firewall rule management across accounts and resources.

Compliance and Governance
