    Exporting Nessus Scan Results to CSV Format

    • Prerequisites

      To export Nessus scan results to CSV format, you need to install Cygwin along with the xsltproc libraries. These tools are necessary for parsing the .nessus file into a .csv file effectively.

    • Downloading Cygwin and xsltproc Libraries

      First, download Cygwin from its official website. During the installation, ensure you include the xsltproc libraries. These libraries are essential for converting the .nessus file format.

    • Parsing .nessus Files

      Once you have Cygwin and xsltproc installed, use xsltproc to parse the .nessus file. This process will convert your Nessus scan data into a .csv file, making it easier to manipulate and analyze your scan results.

    • Saving as .xlsx

      To preserve any changes made to the CSV file, save it as an .xlsx file. This step ensures compatibility with most spreadsheet software, allowing for easier data handling and visualization.

    • Alternative Methods

      For those using tenable.io, while most reporting is PDF-based, you can still access CSV reports. If the direct option is unavailable, consider using the API to generate a CSV report of vulnerabilities.

    How to Export Your Data to CSV Format from Nessus Scan Results

    Exporting Directly from the Nessus Interface

    To export your Nessus scan results directly from the Nessus interface, first log into your Nessus Professional account. Choose the specific scan you wish to export and click on the Export button located at the top-right corner of your screen. From the export options, select CSV format and ensure you include all available columns. Next, click on Generate Report. The report file will be downloaded to your device as a CSV file.

    Using Cygwin and xsltproc Libraries

    If you prefer using Cygwin, start by downloading Cygwin with the xsltproc libraries. These libraries are necessary to parse the .nessus file into a .csv file. Use xsltproc to perform the parsing. Once you have the CSV file, you may want to save it as an .xlsx file in order to make and save any changes easily.

    Opening and Customizing Your CSV Report

    After exporting your scan results, open the CSV file in Excel. A dialog box will appear offering various options to customize your report. Ensure you select the relevant vulnerabilities you need to act on. The CSV file will include columns such as 'Synopsis', 'Description', and 'Solution', providing comprehensive details on the vulnerabilities identified.

    Additional Tools for Exporting Data

    For advanced users, there are tools available to further process and analyze Nessus scan results. One such tool allows exporting Nessus results into a database, which can facilitate easy analysis and extraction of statistics. This can be particularly useful for generating detailed insights and reports from your scan data.
