Building a Secure and Resilient AWS E-commerce Platform

The customer operates a fast-growing online retail platform hosted on Amazon Web Services (AWS). The environment handles customer registrations, online transactions, payment processing, product catalogues and administrative operations. While the infrastructure was operational, security controls were minimal and required significant enhancement to protect against modern cyber threats.

• The AWS environment relied primarily on basic cloud configurations with limited enterprise-grade security controls.
• Public-facing web applications required protection against modern web attacks and malicious bots.
• Administrative access lacked stronger identity verification and privilege management.
• Customer and payment data required enhanced protection and compliance with payment security standards.
• There was limited centralized visibility into security events, threats and incidents.
• The client required a scalable security architecture to support future business growth.

CyberAxis performed a comprehensive assessment of the AWS infrastructure, application architecture, identity management, endpoint security, cloud configurations, logging capabilities, payment security and backup strategy. Based on the findings, a phased security improvement roadmap was developed and implemented using industry best practices and a defense-in-depth approach.

• Deployed Next-Generation Firewall (NGFW) with deep packet inspection and advanced threat analysis.
• Implemented Web Application Firewall (WAF) to protect against OWASP Top 10 attacks and malicious traffic.
• Enabled Multi-Factor Authentication (MFA) and Role-Based Access Control (RBAC) for administrative access.
• Secured customer and payment data using SSL/TLS encryption.
• Implemented PCI DSS-compliant payment gateway with payment tokenisation.
• Deployed Endpoint Detection & Response (EDR/XDR) across critical systems.
• Performed secure code review, vulnerability assessment and penetration testing (VAPT).
• Implemented centralized SIEM monitoring with real-time alerting and incident response.
• Established Data Loss Prevention (DLP), encryption and secure backup strategy.
• Implemented anti-fraud controls, transaction monitoring and bot protection.
• Performed regular patch management, configuration hardening and firewall rule reviews.
• Conducted periodic access reviews following the principle of least privilege.

• Significantly strengthened the security posture of the AWS-hosted e-commerce platform.
• Improved protection against web application attacks, malware and ransomware.
• Reduced the risk of unauthorized access and credential compromise.
• Enhanced payment security through PCI DSS-aligned controls.
• Improved visibility into security events using centralized SIEM monitoring.
• Accelerated incident detection and response capabilities.
• Protected sensitive customer information through encryption and DLP controls.
• Strengthened fraud prevention using transaction monitoring and bot mitigation.
• Improved business resilience with secure backups and disaster recovery readiness.
• Established a scalable and secure cloud architecture capable of supporting future business growth.
