.SYNOPSIS
Parse-Nessus produces a directory of standalone html reports from a .nessus file.
.DESCRIPTION
The Parse-Nessus script parses a .nessus file into collections in memory, then makes a copy of a preexisting html
template and substitutes variables in the template with data from the .nessus file. In addition to a dashboard
of statistics and navigation, a report for each IP address is produced - containing the vulnerabilities for that IP. A
report is also produced that contains all the vulnerabilities in the .nessus file, grouped by IP.
It also supports CIS benchmark reports for the following Windows operating systems
Operating System Benchmark Version
- Windows 7 2.1.0
- Windows 2003 2.0
- Windows 2008 2.1.0
- Windows 2008R2 2.1.0
- Windows 2012 1.0
- Windows 2012R2 2.1.0
IMPORTANT: By default the script assumes you are parsing a Nessus "Basic Network Scan". To process a CIS Benchmark scan, you MUST specify
the -OperatingSystem parameter as well as the -CIS switch. Run Get-Help with -examples for more info.
All output is sent to the current working directory with the format "CUSTOMERNAME-DATE". Simply find and open index.html to see the report.
Note the ONLY browsers that are supported are Chrome, Firefox, and IE11 (non-compatibility mode).
Regarding the template: There are two html template directories that come with this script, one for a Basic Network Scan, and one for
the CIS benchmark scan. They are *REQUIRED* for this script to operate. If the -TemplatePath parameter is not specified, the script
will look for the template directory in the current working directory based on the type of nessus file you specify. The template directories
are named "template-networkscan" and "template-cisbenchmark". Do not rename them or stuff will break.
There is nothing special about the template itself. I downloaded it from html5up.net (free for personal/commercial use). If you wish
to use your own template, simply look through the temlate*.html files in the template directory and pull out the substitution variables (they
all look like |SOMEVARIABLE|) and put them into your own template. You'll also want to search for "Bouvet" and substitute your own company info.
.PARAMETER NessusFilePath
[REQUIRED] This is the path to the exported .nessus file
.PARAMETER CustomerName
[REQUIRED] This is the name of the organization for whom the report was run against. The name is used in the dashboard page.
.PARAMETER TemplatePath
[OPTIONAL] The full path to the directory containing the template files. If this parameter
is not specified, the script will look for a "template" direcotry in the current working directory.
.PARAMETER OperatingSystem
[OPTIONAL] Note this parameter is mandatory if using the -CIS switch. The following strings are accepted for this parameter
- Windows2003
- Windows7
- Windows2008
- Windows2008r2
- Windows2012
- Windows2012r2
.PARAMETER CIS
[OPTIONAL] This parameter indicates to the script that you are targeting a CIS benchmark nessus report.
.PARAMETER DebugMode
[OPTIONAL] Spits out a crap ton of extra information. Mainly used for troubleshooting purposes and those who enjoy roller coasters.
.EXAMPLE
Parse-Nessus.ps1 -NessusFilePath C:\temp\export.nessus -CustomerName "ACME Products"
Parses a routine Basic Network Scan.
.EXAMPLE
Parse-Nessus.ps1 -NessusFilePath C:\temp\export.nessus -CustomerName "ACME Products" -Template "C:\temp\mytemplatedirectory"
Parses a Basic Network Scan but with a custom template. Useful if you plan to roll your own template.
.EXAMPLE
Parse-Nessus.ps1 -NessusFilePath c:\temp\exportwin7.nessus -CustomerName "Acme Products" -OperatingSystem "Windows7" -CIS
Parses a CIS Benchmark Scan which targeted Windows 7 machines.
