CVE-llm_dataset

This dataset is intended to train an LLM model for an utterly CVE-focused input and output.

Data extraction:

For the data extraction, I first downloaded the CVE database from NVD lists and then loaded them using the cve_dataset_2.py and cve_dataset.py both have produce different datasets one is for llama and the other is for openai GPT.

The CVE json files are mapped in this format:

cves:
|
├─1999
|   ├─0xxx
|   |   ├─CVE-1999-0001.json
|   |   ├─....
|   |   └─CVE-1999-0999.json
|   └─1xxx
|      ├─CVE-1999-1000.json
|      ├─....
|      └─CVE-1999-1598.json
└─2023

The programs traverse through these folders extract the data in the files and arrange them into usable formats for the fine-tuning process.

llama2 and Openai Model dataset:

The llama2 fine-tuned dataset follows this format:

    {
        "instruction": "Explain CVE-1999-0001",
        "input": "Explain the vulnerability: CVE-1999-0001",
        "output": "ip_input.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets.\nAffected Products: n/a\nReferences: [{'tags': ['x_refsource_CONFIRM'], 'url': 'http://www.openbsd.org/errata23.html#tcpfix'}, {'name': '5707', 'tags': ['vdb-entry', 'x_refsource_OSVDB'], 'url': 'http://www.osvdb.org/5707'}]\nCVE State: PUBLISHED"
    }

The openai fine-tune dataset follows this format:

        {
            "messages": [
                {"role": "system", "content": "CVE Vulnerability Information"},
                {"role": "user", "content": f"Explain the CVE ID: What does the identifier {cve_id} mean in the context of cybersecurity?"},
                {"role": "assistant", "content": cve_id}
            ]
        },
        {
            "messages": [
                {"role": "system", "content": "CVE Vulnerability Information"},
                {"role": "user", "content": f"Describe the vulnerability: Provide detailed information about the vulnerability for {cve_id}."},
                {"role": "assistant", "content": description}
            ]
        },
        {
            "messages": [
                {"role": "system", "content": "CVE Vulnerability Information"},
                {"role": "user", "content": f"Provide references for further information: Can you share references or external links related to {cve_id}?"},
                {"role": "assistant", "content": references}
            ]
        },
        {
            "messages": [
                {"role": "system", "content": "CVE Vulnerability Information"},
                {"role": "user", "content": f"Explain the state of this CVE: What is the publication or resolution state of {cve_id}?"},
                {"role": "assistant", "content": cve_state}
            ]
        }

The instruction is what we instruct the AI to do with the data provided For example we can command the AI To take in user input analyze it and then based on what he asks returns an answer This is also where we can add a role or a personal to the AI.

The input is the user Input of the main query or data that must be processed by the AI. This is a crucial piece of information that the AI will process in order to provide an output.

The output is the format that we define and tell the AI to generate answers in that format or provide that answer to the question asked.
