Threat Modeling and Security Architecture

Project 2: Implementation of STRIDE for E-Commerce

Prepared by: Aryan Kumar Singh
Amity University Online | Course: IHC - PACS
Project Given By: TCS iON

Introduction & Objectives

Objective: Apply STRIDE threat modeling to a real-world e-commerce application to identify security gaps.
Methodology: Identify threats (Spoofing, Tampering, etc.) and design a secure architecture.
Importance: E-commerce sites handle sensitive financial data and are frequent targets for cyberattacks.
Goal: Reduce security risks through early identification and architectural mitigation.

Application Overview: E-Commerce

System Description:
An online retail platform allowing users to browse products, register, login, and execute secure payments.

Key Components:

Web Frontend (User Interface)
Application Server (Business Logic)
Database (User & Order Data)
Payment Gateway Integration
Admin Panel for Management

Threat Modeling Methodology: STRIDE

Spoofing: Impersonating something or someone else.

Tampering: Modifying code or data without authorization.

Repudiation: Denying responsibility for an action.

Information Disclosure: Exposing confidential data.

Denial of Service: Denying access to valid users.

Elevation of Privilege: Gaining unauthorized access levels.

Identified Threats in E-Commerce

Spoofing
Attackers creating fake user accounts or impersonating admins to gain entry.

Tampering
Manipulation of order pricing or quantities in transit or at rest in the DB.

Information Disclosure
Leakage of customer PII (Personally Identifiable Information) or payment details.

Denial of Service (DoS)
Flooding the server with requests to cause downtime and loss of revenue.

Risk Assessment Methodology

The Risk Formula:
Risk = Likelihood × Impact

Evaluation Scope:
We analyzed technical vulnerabilities, application logic flaws, and potential business impact.

Key Factors:

Likelihood: Ease of execution for an attacker.
Impact: Damage to finances, reputation, or operations.

A 3D rendering of a risk matrix concept, balancing a weight scale with 'Likelihood' on one side and 'Impact' on the other. Professional business abstract style.

Risk Assessment Summary

Chart

Analysis

Critical Risks:
Spoofing and Information Disclosure pose the highest threat to the platform, requiring immediate priority in the security architecture.

High Risks:
Data Tampering and Denial of Service can significantly disrupt business operations.

Proposed Security Architecture

Design Goals:
Protect Data, Prevent Access, Ensure Availability.

Core Components:

Frontend: Secured via HTTPS/TLS 1.3.
App Layer: Strict input validation & RBAC (Role-Based Access Control).
Database: Encrypted at rest and restricted access.
Payment: PCI-DSS compliant gateway integration.

Made by

Security Controls & Mitigation

Technical Controls:
Implementation of TLS encryption, strong password hashing (Argon2/Bcrypt), and CSRF tokens.

Input Validation:
Sanitization of all user inputs to prevent SQL Injection and XSS attacks.

Administrative Controls:
Enforcing least-privilege access policies and conducting regular security audits.

Logging & Monitoring:
Real-time logging of login attempts and transaction anomalies.

Made by

Advanced Security Measures

Web Application Firewall (WAF):
Filters and monitors HTTP traffic between chaos and the internet to block common attacks.
Rate Limiting:
Restricts the number of requests a user can make in a given timeframe to prevent DoS.
Vulnerability Scanning:
Automated tools to detect new security wekanesses in dependencies or configurations.

Made by

Implementation Plan

Phase 1: Foundation
Threat identification (STRIDE), basic authentication setup, and HTTPS enforcement.

Phase 2: Hardening
Apply Role-Based Access Control (RBAC), input validation sanitizers, and setup logging mechanisms.

Phase 3: Advanced Defense
Deploy WAF, configure rate limiting, and conduct penetration testing.

Personal Reflection

This project helped me understand how attackers think and how threats can affect real-world applications. Applying the STRIDE framework made threat identification structured and easy to understand.

The main challenge was mapping theoretical threats to practical application components. This exercise improved my understanding of security architecture and showed how security controls work together to protect systems.

This assignment strengthened my confidence in threat modeling and security design, which will be useful in future cybersecurity roles.
