Model Access and Configuration for Cybersecurity Investment

What data in this category looks like

Cybersecurity investment research data primarily comes from public vulnerability databases, threat intelligence platforms, asset mapping reports, and internal log audit records. Update cadences vary widely: high-severity vulnerability announcements are pushed in real time, regular threat intelligence is synced daily, and asset data is updated weekly. Individual documents have a fixed structure, including fields such as CVE ID, CVSS score, attack vector, affected asset scope, repair priority, and official repair solutions. Most fields are structured strings or numerical values, with units including CVSS scores (0 to 10), timestamps, asset IP ranges, and more.

What constraints do these characteristics impose on the "model access and configuration" link

The cybersecurity investment research scenario has many structured fields, including numerical scores and enumerated attack vectors. This requires configuring dedicated vector encoding rules for structured data during model access to avoid semantic confusion. Data sources with multiple update cadences require configuring synchronization trigger mechanisms divided by data source type, to adapt to differences between real-time high-severity vulnerability pushes, daily regular intelligence syncs, and weekly asset data updates. Individual document lengths vary widely: high-severity vulnerability reports are only a few hundred characters, while asset mapping reports can reach tens of thousands of characters. This requires configuring adaptive segmentation rules to avoid long text truncation or insufficient embedding of short texts. Fields include precise identifiers such as CVE IDs and asset IP ranges, so dedicated keyword recall weights must be configured to improve retrieval accuracy.

How to set the configurations

Configuration Item	Recommended Value	Rationale
`chunkSize`	`800–1200 characters`	Cybersecurity documents have wide length variation: short high-severity reports and long asset reports. This range balances short text integrity and long text segmentation rationality
`recallTopK`	`Top 8–12 results`	Cybersecurity investment research requires covering multi-dimensional intelligence. Too many recall results increase context pressure, while too few will miss critical vulnerability or asset information
`similarityThreshold`	`0.72–0.85`	This balances the need for precise matching of precise fields such as CVE IDs and attack vectors, and fuzzy matching of threat descriptions, to avoid missed detections or false recalls
`structuredEmbeddingConfig`	Configure dedicated embedding dimensions for CVSS scores and CVE IDs	Structured fields include numerical values and unique identifiers. Dedicated embedding improves semantic encoding accuracy
`syncTriggerMode`	Configure based on data source type: set high-severity vulnerabilities to real-time trigger, and the rest to daily/weekly scheduled triggers	Different data sources have widely varying update cadences. Adapting to this reduces unnecessary synchronization and resource usage
`chunkOverlap`	`50–100 characters`	Prevents key information from being truncated after segmentation, and ensures context continuity for long documents

The parameter values provided on this page are all conventional recommendations, used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.

Three common mistakes

Phenomenon: After deploying version 4.8.21, a model_not_supported error occurs when configuring a third-party model. Version 4.8.9 runs normally. Cause: Version 4.8.21 updated the access verification logic for third-party models, and is not compatible with the interface return format of older models.
Phenomenon: After enabling the indexing model, the number of retrieval results is always 0. Cause: structuredEmbeddingConfig was not configured to apply dedicated embedding to fields such as CVE IDs and CVSS scores, resulting in structured data failing to be correctly vector-encoded.
Phenomenon: A timeout error occurs when processing long documents such as asset mapping reports. Cause: The PARSE_FILE_TIMEOUT_SECONDS parameter was not adjusted to a range suitable for long text processing, or a reasonable chunkSize was not set to avoid segmentation overload.

How to confirm the configuration is complete

Upload a standard cybersecurity vulnerability report, review the parsed segmentation results to confirm that the segmentation length aligns with the configured chunkSize range, with no obvious truncation or redundant content.
Initiate a retrieval for a known CVE ID, verify whether the target CVE ID is included in the recall results, and adjust the similarityThreshold to match the accuracy required by the business.
Trigger a data source synchronization task, check whether the synchronization logs include the trigger time and synchronization status of each data source, and confirm that the syncTriggerMode configuration takes effect.
Test the parsing and embedding process for a long document such as a 10,000-character asset report, confirm that no timeout errors occur, and that segment overlap matches the configured chunkOverlap parameter.
