Having a well-defined list of assets and clear boundaries ensures accurate mapping of attack techniques in later stages.
Step 2: Choose ATT&CK Elements
Pick elements based on the threats your organization faces.
ATT&CK Matrix Overview
The ATT&CK matrix is structured into tactics (columns) and techniques (rows). Here's a quick breakdown to guide your selection:
| Matrix Component | Description | How to Choose |
|---|---|---|
| Tactics | Goals attackers aim to achieve | Match to your business context and asset types |
| Techniques | Specific methods attackers use | Focus on your technical setup and known vulnerabilities |
| Sub-techniques | Detailed variations of techniques | Consider system configurations and deployment models |
Choosing Tactics
When selecting tactics, focus on those that align with your specific environment:
- Review Asset Types: Match tactics to your assets, including both digital and physical elements. Pay attention to network architecture and access points.
- Assess Business Operations: Consider industry-specific threats, regulatory requirements, and operational vulnerabilities.
Choosing Techniques
Techniques should be chosen based on a thorough analysis of your systems. Here’s how to approach it:
- Environment Assessment: Look at your infrastructure, including on-premises and cloud systems. Identify potential entry points and vulnerabilities.
-
Risk-Based Prioritization: Focus on techniques based on:
- Past incident data
- Threat intelligence for your industry
- Existing security measures
- Available resources
- Technical Feasibility: Prioritize techniques that are most likely to target your specific setup.
Using tools like GRC (Governance, Risk, and Compliance) platforms can help streamline this process. For instance, Cycore Secure (https://cycoresecure.com) offers solutions to manage compliance tools within your security framework.
Risk Assessment Matrix
A risk assessment matrix can help you prioritize techniques effectively:
| Risk Level | Technique Traits | Response Plan |
|---|---|---|
| Critical | Exploits with high impact | Act immediately |
| High | Active threats with moderate impact | Address soon |
| Medium | Potential threats with limited impact | Plan for review |
| Low | Theoretical risks with minimal impact | Monitor as needed |
Focus on a targeted approach rather than trying to cover every possible attack vector. This ensures effective threat modeling and smarter resource allocation. Once techniques are selected, map out attack paths to complete your threat modeling framework.

Step 3: Map Attack Paths
Once you’ve selected the relevant ATT&CK elements, the next step is to map out attack paths. This helps you understand how different techniques can combine into real-world threat scenarios.
Create Attack Chains
Build complete attack sequences by logically connecting tactics and techniques. Use your asset inventory to guide this process:
| Attack Chain Component | Description | Key Considerations |
|---|---|---|
| Initial Access | Entry point techniques | Think about external-facing systems and user endpoints |
| Progression Steps | Techniques used to move deeper | Consider lateral movement opportunities |
| Target Impact | Techniques aimed at the final goal | Focus on scenarios involving critical asset compromise |
Start with your most important assets and work backward to identify potential entry points. Include details like prerequisites, permissions, dependencies, network paths, and data flows in your documentation.
Risk Level Assessment
Evaluate and prioritize each attack path based on two factors:
- Likelihood: Consider complexity, required resources, detection difficulty, and historical data.
- Impact: Assess the potential scope of data breaches, service disruptions, and financial or reputational harm.
This scoring system helps you focus on the most pressing threats and sets the stage for reviewing your security controls in the next step.
Attacker Goals Analysis
Understanding what motivates attackers adds another layer to your risk assessment. It highlights which paths are likely to be targeted.
| Attacker Type | Common Goals | Attack Path Characteristics |
|---|---|---|
| Cybercriminals | Financial gain | Target assets that can be monetized |
| Nation-state | Intelligence gathering | Favor paths that ensure long-term persistence |
| Hacktivists | Reputation damage | Focus on public-facing systems |
| Insiders | Varied objectives | Rely on internal access points |
For each attack path, note the capabilities required, expected dwell time, detection windows, and potential mitigation strategies.
Use this analysis to disrupt the most likely attack chains. Strengthen your defenses by targeting critical links and consider adding automated security measures at key points to improve both detection and prevention.
Step 4: Review Security Controls
Once you've outlined attack paths, it's time to assess how your current security measures handle these threats.
Control Mapping
Take stock of your security controls and align them with specific ATT&CK techniques.
| Control Category | Mapping Focus | Key Points to Address |
|---|---|---|
| Preventive | Focus on initial access and execution methods | Network segmentation, access controls, endpoint protection |
| Detective | Target persistence and privilege escalation tactics | Logging systems, SIEM tools, behavior monitoring |
| Responsive | Address impact and data exfiltration methods | Incident response plans, backup systems, recovery strategies |
For each control, document its status, how well it works, and any dependencies it may have.
Security Gap Analysis
Using your control mapping as a foundation, pinpoint areas where your defenses fall short. Pay attention to:
- Coverage: Identify ATT&CK techniques that aren't adequately addressed.
- Effectiveness: Measure how well your controls perform under attack scenarios.
- Resource Allocation: Determine where to adjust investments based on risk levels.
Control Testing
Regularly test your security measures to ensure they perform as expected.
