# MITRE ATT&CK Analysis Workflows

## Workflow 1: Threat Actor TTP Mapping

```
[Threat Report] --> [Extract Behaviors] --> [Map to ATT&CK] --> [Navigator Layer]
                                                                       |
                                                                       v
                                                              [Detection Priorities]
```

### Steps:
1. **Report Ingestion**: Obtain threat intelligence report (vendor, OSINT, internal)
2. **Behavior Extraction**: Identify adversary actions described in the report
3. **Technique Mapping**: Map each behavior to ATT&CK technique IDs using the ATT&CK knowledge base
4. **Sub-technique Precision**: Drill down to sub-techniques where procedure details allow
5. **Layer Creation**: Generate ATT&CK Navigator layer with mapped techniques
6. **Priority Assessment**: Rank techniques by detection feasibility and impact

## Workflow 2: Detection Gap Analysis

```
[Current Detections] --> [Detection Layer] --> [Overlay with Threat Layer] --> [Gap Layer]
                                                                                    |
                                                                                    v
                                                                          [Engineering Backlog]
```

### Steps:
1. **Detection Inventory**: Catalog existing detection rules mapped to ATT&CK techniques
2. **Detection Layer**: Create Navigator layer showing detected techniques (green)
3. **Threat Layer**: Create layer showing adversary techniques (red)
4. **Overlay Analysis**: Combine layers to identify uncovered threat techniques
5. **Gap Prioritization**: Rank gaps by threat actor relevance and detection feasibility
6. **Engineering Plan**: Create detection engineering backlog from prioritized gaps

## Workflow 3: Cross-Actor Comparison

```
[Group A TTPs] --+
                 |--> [Intersection Analysis] --> [Common Techniques] --> [Priority Detections]
[Group B TTPs] --+                                                               |
                 |                                                               v
[Group C TTPs] --+                                                    [Unique Techniques per Group]
```

### Steps:
1. **Group Selection**: Choose threat groups relevant to your industry/region
2. **TTP Extraction**: Pull technique lists for each group from ATT&CK
3. **Common Analysis**: Find techniques shared across all selected groups
4. **Unique Analysis**: Identify techniques unique to specific groups
5. **Detection ROI**: Prioritize detections for commonly used techniques (highest coverage ROI)
6. **Actor Attribution**: Use unique techniques as potential attribution indicators

## Workflow 4: Campaign-to-TTP Analysis

```
[Campaign IOCs] --> [Sandbox/Analysis] --> [Behavior Extraction] --> [TTP Mapping]
                                                                          |
                                                                          v
                                                                 [Compare to Known Groups]
                                                                          |
                                                                          v
                                                                 [Attribution Hypothesis]
```

### Steps:
1. **IOC Collection**: Gather campaign IOCs (malware hashes, C2 domains, phishing emails)
2. **Dynamic Analysis**: Execute samples in sandbox, capture behavioral artifacts
3. **Behavior Documentation**: Document file operations, registry changes, network connections, process activity
4. **ATT&CK Mapping**: Map observed behaviors to techniques and sub-techniques
5. **Group Comparison**: Compare campaign TTPs against known group profiles
6. **Attribution Assessment**: Assess likelihood of attribution based on TTP overlap

## Workflow 5: Threat-Informed Defense

```
[ATT&CK Mappings] --> [Data Source Analysis] --> [Telemetry Assessment] --> [Control Mapping]
                                                                                   |
                                                                                   v
                                                                          [Security Roadmap]
```

### Steps:
1. **Threat Profile**: Identify relevant threat actors and their techniques
2. **Data Source Mapping**: Determine which data sources can detect each technique
3. **Telemetry Audit**: Assess which data sources are currently collected
4. **Control Assessment**: Map existing security controls to technique mitigations
5. **Gap Identification**: Find techniques with neither detection nor mitigation coverage
6. **Roadmap Creation**: Build security improvement roadmap addressing highest-risk gaps
