NanoSIEM Dataset
NanoSIEM is a provenance-aware cybersecurity, SIEM and legal-source retrieval corpus. It contains normalized vulnerability and guidance records, official-source registries, synthetic redacted SIEM events and curated Turkish safety-oriented question-answer examples.
Data policy
Records retain source URLs, retrieval time, jurisdiction, identifiers and confidence. Legal records are informational and jurisdiction-sensitive. Synthetic SIEM events do not represent real people or organisations. Do not infer an incident, vulnerability, crime or liability from a single record.
The primary Dataset Viewer table is security.jsonl. The Git repository contains only a small seed; the full downloaded corpus is generated by make dataset-full and should be uploaded to the dataset repository rather than committed to the source repository. Source registries, legal registries, SIEM examples and the manifest are uploaded as .json.txt metadata so the viewer does not incorrectly cast different schemas into one table.
The corpus is refreshed from official NVD/CVE, CISA KEV, OWASP, MITRE ATT&CK/CWE, NIST, EUR-Lex, ECHR, KVKK and Turkish Mevzuat sources. curated_qa.jsonl contains reviewed scenario answers; raw/ contains the downloaded source payloads used to build records when a full ingest is run. Review manifest.json and each record's provenance before relying on it.
