Threat Modeling & Architecture Review

Analyze Use Cases and Logical Flow

• We begin by thoroughly analysing the application’s use cases and logical workflows by reviewing business requirement documents. This step ensures a deep understanding of the application’s design, and hosting infrastructure, helping to identify key interaction points, potential risks, and the critical paths that influence the application’s functionality.

Map the Controls based on Application Architecture

To identify architecture-level weaknesses, based on the application understanding, we create questions that map security controls with the application, list of some of these controls are Application Details (Purpose, Access Levels, Technology Stack, etc.)

• Third-Party Integrations
• Data Protection
• Authentication
• Session Management
• Access Control
• Cryptography
• Input Validation
• Output Encoding/Escaping
• Error Handling and Logging
• HTTP/Communication Security
• Security Configuration
• Platforms
• Serverless
• Cloud Components
• AI/ML Implementations

Detailed Discussions with Architects and Developers

• We ask targeted questions and explore specific security controls to ensure comprehensive coverage of all aspects of the system's design. If required, in-depth discussions with architects and developers are conducted to gather a full understanding of the architecture. The goal here is to evaluate each layer of the architecture to discover potential weaknesses and vulnerabilities that could be exploited.

Suggest Mitigation Strategies

• For each identified vulnerability, we propose tailored mitigation strategies to reduce or eliminate the associated risks. This step ensures that all potential weaknesses are addressed with actionable solutions.

Deliver a Threat Model and Exploit Scenarios

• We also provide a detailed threat model outlining potential attack vectors and possible exploit scenarios. This model helps the development team visualize the impact of vulnerabilities and prioritize areas that need immediate attention.

Offer Defence and Countermeasure Guidance

• At the end of the review, we deliver practical defense suggestions and countermeasures to guide developers in securing the application. This includes recommendations for security best practices, coding standards, and architectural enhancements that reinforce the system’s security. This structured approach ensures a comprehensive review of the application architecture, with actionable insights and defense strategies to strengthen the system against potential threats.
