What the Data for This Category Looks Like
The data for cybersecurity intelligent due diligence reports primarily comes from files exported by automated vulnerability scanning tools, synchronized data from asset mapping platforms, and archived compliance audit documents. Update cycles align with scan task triggers. The update frequency of data sources for a single due diligence report ranges from daily to on-demand synchronization. Most documents are structured PDFs or Excel files, with fixed fields: asset identifiers (IP/domain names), vulnerability IDs, CVSS scores, impact scopes, and remediation plans. They also include attachments such as scan logs and port mapping tables. Field units include numeric port numbers, floating-point CVSS scores, and date-type discovery times. Some fields support multilingual text.
Constraints Imposed on Document Parsing and Chunking
The structured nature of cybersecurity intelligent due diligence reports creates multiple constraints for parsing and chunking. First, Excel documents with multiple worksheets must be split into chunks grouped by assets, to avoid broken field associations across worksheets. Second, fields with clear units such as CVSS scores and port numbers must retain the binding relationship between the field and its corresponding value during chunking. Complete information for a single vulnerability cannot be split. Third, scan log attachments included in documents must be treated as separate associated chunks, bound to the main asset entry. Frequently updated data sources may introduce version differences. Parsing must retain version number fields to distinguish batches of due diligence data. Finally, a single report may contain hundreds of asset vulnerability entries. Chunk length must be controlled to fit index limits.
Configuration Settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Cybersecurity due diligence reports include large numbers of scan log attachments. Parsing takes longer than generic documents, so extending the timeout threshold prevents mid-process interruptions |
maxChunkSize | 800–1200 characters | A single vulnerability entry includes multiple fields such as asset identifiers, CVSS scores, and remediation plans. Excessively long chunks will damage the integrity of field associations |
chunkOverlap | 50–100 characters | Preserves contextual continuity between vulnerability descriptions and subsequent remediation plans, preventing semantic breaks |
PARSE_EXCEL_SHEET_MODE | Split chunks by worksheet | Excel files for cybersecurity reports are often stored grouped by assets. Splitting by worksheet retains grouping logic and improves retrieval accuracy |
SIMILARITY_THRESHOLD | 0.75–0.85 | Accurately matches the association between vulnerability IDs and corresponding fields, filtering out irrelevant low-similarity entries |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Accommodates the needs of full scan reports with multiple log attachments, preventing upload failures |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: A
504 Gateway Timeouterror is returned when parsing large cybersecurity reports, or the platform prompts a request timeout. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted. Using the default timeout threshold fails to cover the parsing time of large log files. - Symptom: Fewer results than actual entries are returned when retrieving specific grouped data from Excel in the knowledge base. Cause: The worksheet-based chunk splitting configuration was not enabled, or the chunk length was set too long, causing entries in some worksheets to be truncated and data to not be fully extracted.
- Symptom: When retrieving vulnerability information, the CVSS score and remediation plan for a single vulnerability belong to different chunks and cannot be recalled together. Cause: The
maxChunkSizesetting is too small, splitting the complete field group for the same vulnerability, or insufficient contextual overlap was retained, leading to semantic breaks.
How to Verify Proper Configuration
- Upload a single Excel due diligence report with multiple worksheets, then check the knowledge base chunk list to confirm that each worksheet corresponds to an independent chunk group.
- Initiate a search for a specific vulnerability ID, then confirm that returned results include all associated fields for that vulnerability, with no missing split fields.
- Upload the largest size test report, then check that no timeout errors occur during parsing, and confirm that the timeout configuration fits current file parsing requirements.
- Adjust the
maxChunkSizeparameter, compare retrieval result completeness across different values, then select a configuration that fits the business scenario.
