Third-Party Payment Processing Infrastructure Security Assessment
Served as third-party security auditor for NYC Taxi and Limousine Commission and their payment processing vendor. This engagement required comprehensive auditing of front-end and back-end infrastructure to ensure compliance with credit card processing security regulations.
The project involved detailed risk assessments, security analysis, and remediation recommendations. Through extensive mapping and documentation of system configurations and network connections, I identified critical vulnerabilities in redundancy and helped establish robust failsafe mechanisms to protect against service outages.
Conducted comprehensive assessment of payment processing infrastructure, evaluating terminal systems in taxi cabs and back-end processing environments for PCI DSS compliance and payment security standards.
Performed detailed risk assessments identifying security vulnerabilities, configuration weaknesses, and potential attack vectors across the payment ecosystem.
Created comprehensive documentation of system configurations, network topology, data flows, and connection points. Developed network diagrams and security architecture documentation.
Identified critical gaps in system redundancy and single points of failure. Discovered issues with existing failsafe mechanisms that could lead to service disruptions.
Developed detailed remediation plans and security enhancement recommendations. Provided guidance for implementing improved redundancy and robust failover procedures.
Validated adherence to PCI DSS standards, evaluated encryption protocols for cardholder data protection, and assessed access controls and monitoring capabilities.
Comprehensive Assessment: Successfully audited entire payment processing ecosystem from terminals through back-end systems, providing complete visibility into security posture.
Redundancy Improvements: Identified weaknesses in failover capabilities. Recommendations led to enhanced failsafe mechanisms protecting against outages.
Enhanced Compliance: Delivered compliance assessment and remediation roadmap enabling the organization to address gaps and strengthen PCI DSS alignment.
Detailed Documentation: Produced comprehensive system documentation including topology maps, configuration details, and security diagrams.
Risk Mitigation: Developed prioritized remediation plan addressing vulnerabilities and enabling systematic security improvement.
