+
+The [IriusRisk](https://www.iriusrisk.com/) parser for DefectDojo supports imports from CSV format. This document details the parsing of IriusRisk threat model CSV exports into DefectDojo field mappings, unmapped fields, and location of each field's parsing code for easier troubleshooting and analysis.
+
+## Supported File Types
+
+The IriusRisk parser accepts CSV file format. To generate this file from IriusRisk:
+
+1. Log into your IriusRisk console
+2. Navigate to the project containing your threat model
+3. Export the threats as CSV
+4. Save the file with a `.csv` extension
+5. Upload to DefectDojo using the "IriusRisk Threats Scan" scan type
+
+## Default Deduplication Hashcode Fields
+
+By default, DefectDojo identifies duplicate Findings using these [hashcode fields](https://docs.defectdojo.com/en/working_with_findings/finding_deduplication/about_deduplication/):
+
+- title
+- cwe
+- line
+- file_path
+- description
+
+The parser also populates `unique_id_from_tool` with a SHA-256 hash of the Component, Threat, and Risk Response fields, providing an additional layer of deduplication across reimports.
+
+### Sample Scan Data
+
+Sample IriusRisk scans can be found in the [sample scan data folder](https://github.com/DefectDojo/django-DefectDojo/tree/master/unittests/scans/iriusrisk).

+
+## Special Processing Notes
+
+### Status Conversion
+
+IriusRisk uses a five-level risk scale that is mapped to DefectDojo severity levels (lines 8-14):
+
+- `Critical` → Critical
+- `High` → High
+- `Medium` → Medium
+- `Low` → Low
+- `Very low` → Info
+
+Any unrecognized risk value defaults to Info (line 53). The mapping uses the "Current Risk" column, which reflects the risk level accounting for existing controls and represents the most accurate current exposure.
+
+### Title Format
+
+Finding titles are derived from the "Threat" column (line 51). Threat descriptions longer than 150 characters are truncated to 147 characters with a "..." suffix appended. Shorter threat texts are used as-is without modification.
+
+### Description Construction
+
+The parser constructs a structured markdown description containing all relevant CSV fields (lines 56-72):
+
+1. Full threat text (untruncated, regardless of title truncation)
+2. Component name
+3. Use case (threat category, e.g., "Elevation of Privilege", "Networking")
+4. Source (e.g., "Created by Rules Engine")
+5. Inherent Risk (pre-control risk level)
+6. Current Risk (risk with existing controls)
+7. Projected Risk (risk after planned mitigations)
+8. Countermeasure Progress (percentage complete)
+9. Weakness Tests (test status)
+10. Countermeasure Tests (test status)
+11. Owner (conditionally included only when the field contains a value)
+12. STRIDE-LM (conditionally included only when the field contains a value)
+
+Each field is formatted as a bold markdown label followed by the value, with fields separated by newlines.
+
+### MITRE Reference / CWE Extraction
+
+The parser reads the "MITRE reference" column (lines 79-87) and applies conditional mapping:
+
+- If the value matches the pattern `CWE-NNN` (e.g., "CWE-284"), the integer portion is extracted and set on the finding's `cwe` field.
+- If the value is present but does not match the CWE pattern (e.g., "T1059" for a MITRE ATT&CK technique), the full value is stored in the finding's `references` field.
+- If the column is empty, neither field is set.
+
+### Mitigation Construction
+
+The mitigation field is populated directly from the "Risk Response" column (line 94), which contains the IriusRisk mitigation status in the format: "Planned mitigation: X%. Mitigated: Y%. Unmitigated: Z%." This preserves the original IriusRisk mitigation tracking percentages.
+
+### Active/Inactive Logic
+
+Findings are set to active by default (line 96). When the "Current Risk" value is "Very low", the finding is set to inactive, as this indicates the threat has been fully mitigated through implemented countermeasures.
+
+### Deduplication
+
+The parser generates a `unique_id_from_tool` by computing a SHA-256 hash of the Component, Threat, and Risk Response fields concatenated with pipe delimiters (lines 74-77). This ensures that each distinct combination of component, threat, and mitigation state produces a unique identifier. On reimport, findings with matching unique IDs are recognized as the same finding rather than being duplicated.
+
+### Duplicate Rows in Source Data
+
+IriusRisk CSV exports can contain multiple rows with the same Component and Threat but different Risk Response values. These represent distinct countermeasure paths for the same threat. Each row is imported as a separate finding, distinguished by its unique ID which incorporates the Risk Response field.
