## Threat Modeling and Security Architecture
- Prepared by Aryan Kumar Singh for Amity University Online.
- Focuses on the implementation of STRIDE for E-Commerce systems.

## Introduction & Objectives
- Goal: Apply STRIDE to identify security gaps in e-commerce.
- Methodology: Identify Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege.

## Application Overview: E-Commerce
- Components: Web Frontend, Application Server, Database, Payment Gateway, and Admin Panel.

## Threat Modeling Methodology: STRIDE
- **S**poofing: Impersonation.
- **T**ampering: Modification of data.
- **R**epudiation: Denying actions.
- **I**nformation Disclosure: Data leaks.
- **D**enial of Service: Service downtime.
- **E**levation of Privilege: Unauthorized access.

## Risk Assessment & Identified Threats
- Risk Calculation: Risk = Likelihood × Impact.
- Critical threats identified: Spoofing and Information Disclosure.
- High risks: Data Tampering and DoS.

## Proposed Security Architecture
- Frontend: Secured via HTTPS/TLS 1.3.
- App Layer: RBAC and strict input validation.
- Database: Encryption at rest.
- Payment: PCI-DSS compliance.

## Security Controls & Advanced Measures
- Technical: TLS encryption, Argon2/Bcrypt hashing, CSRF tokens.
- Infrastructure: Web Application Firewall (WAF), rate limiting, and vulnerability scanning.

## Implementation Plan
- Phase 1: STRIDE identification and HTTPS enforcement.
- Phase 2: RBAC and logging setup.
- Phase 3: WAF deployment and penetration testing.
