AWS Network Access Analyzer Overview

AWS Cloud Hands-on Lab Practice Series

Published Aug 27, 2024
Project Overview —
The AWS Network Access Analyzer project aims to provide a comprehensive understanding and practical demonstration of the Network Access Analyzer (NAA) feature within Amazon VPC. This lab will equip participants with the knowledge and skills to effectively assess, verify, and improve their VPC network security posture.
Solutions Architecture —
First Let’s understand the real world use case :
Network Access Analyzer uses automated reasoning algorithms to analyze the network paths that a packet can take between resources in an AWS network.
The key concepts of the Network Access Analyzer are:
  • Network Access Scope
  • Findings
A Network Access Scope determines the types of findings that the analysis produces. You add entries to MatchPaths to specify the types of network paths to identify. You add entries to ExcludePaths to specify the types of network paths to exclude.
Findings are potential paths in your network that match any of the MatchPaths entries in your Network Access Scope, but do not match any of the ExcludePaths entries in your Network Access Scope.
  1. Security Audits and Compliance Verification:
  • Use Case: A financial services company needs to ensure that their network configurations comply with industry regulations such as PCI-DSS or HIPAA.
  • Solution: The Network Access Analyzer can be used to scan the VPC configurations and identify any non-compliant access patterns, helping the company verify that their network setup adheres to the required security standards.
2. Proactive Threat Detection:
  • Use Case: A healthcare provider wants to minimize the risk of unauthorized access to sensitive patient data stored in their AWS environment.
  • Solution: The analyzer helps identify potential security gaps or misconfigurations, such as overly permissive security groups, that could be exploited by malicious actors, allowing the provider to tighten security controls before an incident occurs.
3. Network Segmentation Validation:
  • Use Case: An e-commerce platform separates its production, development, and testing environments within the same VPC to maintain strict isolation between them.
  • Solution: The Network Access Analyzer can verify that the segmentation is correctly configured, ensuring that there is no unintended communication between environments that could lead to data leakage or cross-environment attacks.
4. Incident Response and Forensics:
  • Use Case: A tech company experiences a potential security breach and needs to quickly assess if the VPC’s network configuration contributed to the incident.
  • Solution: The Network Access Analyzer can be used to analyze the network access paths that existed at the time of the incident, helping the incident response team identify misconfigurations or unauthorized access that may have facilitated the breach.
