DREAD Threat Modeling Application

Executive Summary

This application facilitates threat modeling using the DREAD methodology (Damage Potential, Reproducibility, Exploitability, Affected Users, Discoverability). It enables security teams to identify assets, define threats, score them based on DREAD criteria, propose mitigations, and document findings. Results are stored in a dynamic threat table, importable and exportable to Excel, with an Action Log to track activities, ensuring a prioritized approach to managing security risks.

1. Preparation

Prepare the organization for a DREAD-based threat modeling process.

• Define the scope (e.g., application, network, cloud services).
• Assemble a team including developers, security analysts, and stakeholders.
• Understand DREAD criteria: Damage Potential, Reproducibility, Exploitability, Affected Users, Discoverability.
• Prepare tools for documentation (this app’s threat table will store results).

2. Asset Identification

Identify critical assets to be protected.

• List systems, data, or processes (e.g., customer database, payment API).
• Document asset details in the form below.

3. Threat Identification

Identify potential threats to the system.

• Specify threats (e.g., data breach, service disruption).
• Define attack vectors (e.g., phishing, SQL injection).
• Document threats in the form below.

4. DREAD Scoring

Score each threat using DREAD criteria.

• Damage Potential: How severe is the impact? (Low/Medium/High)
• Reproducibility: How easily can the attack be repeated? (Low/Medium/High)
• Exploitability: How easy is it to execute the attack? (Low/Medium/High)
• Affected Users: How many users are impacted? (Low/Medium/High)
• Discoverability: How likely is the vulnerability to be found? (Low/Medium/High)
• Enter scores in the form below.

5. Mitigation Planning

Define mitigations to address each threat.

• Identify existing controls (e.g., firewalls, authentication).
• Propose new mitigations (e.g., input validation, monitoring).
• Specify implementation plans (e.g., owner, timeline).
• Document mitigations in the form below.

Notify Stakeholders

• Coordinate with relevant parties for mitigation implementation.
• Use a professional tone and log communications. Example:
  Subject: DREAD Threat Modeling Coordination Request Dear [Stakeholder Contact], We are conducting a DREAD-based threat modeling exercise and have identified a threat to [asset], described as [threat description, e.g., data breach via phishing]. The DREAD scores indicate high [e.g., Damage Potential, Exploitability]. Proposed mitigations include: - [e.g., Enhanced email filtering] - [e.g., User awareness training] Please confirm these actions or suggest alternatives by [deadline]. Contact us for further details. Best regards, [Your Name] [Your Organization] [Contact Information]
