    <#
    .SYNOPSIS
    Exports data to a CSV file, archives the CSV file and a log file in a zip file, and returns the path to the zip file.
    .DESCRIPTION
    The Build-ReportArchive function exports data to a CSV file, archives the CSV file and a log file in a zip file,
    and returns the path to the zip file. The function takes four parameters: $Export (the data to export),
    $csv (the name of the CSV file to create), $zip (the name of the zip file to create), and $log
    (the name of the log file to create). The function writes information about the export and archive process
    to the log file, and any errors that occur are also logged.
    .PARAMETER Export
    Specifies the data to export.
    .PARAMETER csv
    Specifies the name of the CSV file to create.
    .PARAMETER zip
    Specifies the name of the zip file to create.
    .PARAMETER log
    Specifies the name of the log file to create.
    .INPUTS
    The function accepts data as input from the pipeline.
    .OUTPUTS
    The function returns the path to the zip file that contains the archived CSV and log files.
    .EXAMPLE
    PS C:\> $Export = Get-ADUser -Filter *
    PS C:\> $CsvFile = "C:\Temp\ExportedData.csv"
    PS C:\> $ZipFile = "C:\Temp\ExportedData.zip"
    PS C:\> $LogFile = "C:\Temp\ExportedData.log"
    PS C:\> Build-ReportArchive -Export $Export -csv $CsvFile -zip $ZipFile -log $LogFile
 
    In this example, the Build-ReportArchive function is used to export all AD users to a CSV file,
    archive the CSV file and a log file in a zip file, and return the path to the zip file. The
    exported data is passed as input to the function using the $Export parameter, and the names
    of the CSV, zip, and log files are specified using the $csv, $zip, and $log parameters, respectively.
    .NOTES
    This function requires PowerShell 5.0 or later.

    <#
    .SYNOPSIS
    Gets the extended rights granted to a specified Active Directory object.
    .DESCRIPTION
    The Get-AdExtendedRight function returns a list of dangerous extended rights granted to a specified Active Directory object.
    The function checks each access control entry in the object's security descriptor to see if it grants an extended right,
    and if so, it maps the object type of the access control entry to a name of a dangerous extended attribute.
    .PARAMETER ADObject
    Specifies the Active Directory object to get extended rights for.
    .INPUTS
    The function accepts an Active Directory object as input.
    .OUTPUTS
    The function returns a list of dangerous extended rights granted to the specified Active Directory object.
 
        The output is an array of PowerShell objects that contain the following properties:
 
            - Actor: The security principal that has been granted the extended right.
            - CanActOnThePermissionof: The name and distinguished name of the Active Directory object that the extended right has been granted to.
            - WithExtendedRight: The name of the dangerous extended right that has been granted.
    .EXAMPLE
    PS C:\> $ADObject = Get-ADUser -Identity "jdoe"
    PS C:\> $ER = Get-AdExtendedRight -ADObject $ADObject
    PS C:\> $ER
 
    Actor : CONTOSO\ITAdmin

    .SYNOPSIS
    Initializes the environment by installing required PowerShell modules.
    .DESCRIPTION
    This function installs PowerShell modules required by the script. It can install public or pre-release versions of the module, and it supports installation for all users or current user.
    .PARAMETER PublicModuleNames
    An array of module names to be installed. Required when using the Public parameter set.
    .PARAMETER PublicRequiredVersions
    An array of required module versions to be installed. Required when using the Public parameter set.
    .PARAMETER PrereleaseModuleNames
    An array of pre-release module names to be installed. Required when using the Prerelease parameter set.
    .PARAMETER PrereleaseRequiredVersions
    An array of required pre-release module versions to be installed. Required when using the Prerelease parameter set.
    .PARAMETER Scope
    The scope of the module installation. Possible values are "AllUsers" and "CurrentUser".
    .PARAMETER ImportModuleNames
    The specific modules you'd like to import from the installed package to streamline imports.
    Example "Microsoft.Graph.Authentication","Microsoft.Graph.Identity.SignIns"
    .EXAMPLE
    Initialize-ModuleEnv -PublicModuleNames "PSnmap", "Microsoft.Graph" -PublicRequiredVersions "1.3.1","1.23.0" -Scope AllUsers
 
    This example installs the PSnmap and Microsoft.Graph modules in the AllUsers scope with the specified versions.
    .EXAMPLE
    $params1 = @{
        PublicModuleNames = "PSnmap","Microsoft.Graph"
        PublicRequiredVersions = "1.3.1","1.23.0"
        ImportModuleNames = "Microsoft.Graph.Authentication", "Microsoft.Graph.Identity.SignIns"
        Scope = "CurrentUser"
    }
    Initialize-ModuleEnv @params1
 
    This example installs Microsoft.Graph and Pester Modules in the CurrentUser scope with the specified versions.
    It will attempt to only import Microsoft.Graph Modules matching the names in the "ImportModulesNames" array.
    .EXAMPLE
    $params2 = @{
        PrereleaseModuleNames = "Sampler", "Pester"
        PrereleaseRequiredVersions = "2.1.5", "4.10.1"
        Scope = "CurrentUser"
    }
    Initialize-ModuleEnv @params2
    This example installs the PreRelease Sampler and Pester Modules in the CurrentUser scope with the specified versions.
    Double check https://www.powershellgallery.com/packages/<ModuleName>/<ModuleVersionNumber>
    to verify if the "-PreRelease" switch is needed.

    <#
    .SYNOPSIS
    Retrieves the most recent LastLogon timestamp for a specified Active Directory user account from all domain controllers and outputs it as a DateTime object.
    .DESCRIPTION
    This function takes a SamAccountName input parameter for a specific user account and retrieves the most recent
    LastLogon timestamp for that user from all domain controllers in the Active Directory environment.
    It then returns the LastLogon timestamp as a DateTime object. The function also checks the availability
    of each domain controller before querying it, and writes an audit log with a list of available and
    unavailable domain controllers.
    .PARAMETER SamAccountName
    Specifies the SamAccountName of the user account to be checked for the most recent LastLogon timestamp.
    .INPUTS
    A SamAccountName string representing the user account to be checked.
    .OUTPUTS
    A DateTime object representing the most recent LastLogon timestamp for the specified user account.
    .EXAMPLE
    Get-ADUserLogonAudit -SamAccountName "jdoe"
    Retrieves the most recent LastLogon timestamp for the user account with the SamAccountName "jdoe" from all
    domain controllers in the Active Directory environment.
    .NOTES
    This function is designed to be run on the primary domain controller, but it can be run on any domain
    controller in the environment.
    It requires the Active Directory PowerShell module and appropriate permissions to read user account data.
    The function may take some time to complete if the Active Directory environment is large or the domain
    controllers are geographically distributed.

    <#
    .SYNOPSIS
    Discovers local network and runs port scans on all hosts found for specific or default sets of ports and displays MAC ID vendor info.
    .DESCRIPTION
    Scans the network for open ports specified by the user or default ports if no ports are specified.
    Creates reports if report switch is active. Adds MACID vendor info if found.
    .NOTES
    Installs PSnmap if not found and can output a report, or just the results.
 
    Throttle Limit Notes:
        Number of hosts: 65,536
        Scan rate: 32 hosts per second (Throttle limit)
        Total scan time: 2,048 seconds (65,536 / 32 = 2,048)
        Total data transferred: 65,536 kilobytes (1 kilobyte per host)
        Average network bandwidth: 32 kilobits per second (65,536 kilobytes / 2,048 seconds = 32 kilobits per second)
    .LINK
    Specify a URI to a help page, this will show when Get-Help -Online is used.
    .EXAMPLE
    Get-NetworkAudit -report
    .PARAMETER Ports
    Default ports are:
    "21", "22", "23", "25", "53", "67", "68", "80", "443",
    "88", "464", "123", "135", "137", "138", "139",

function Merge-ADAuditZip {
    <#
    .SYNOPSIS
    Combines multiple audit report files into a single compressed ZIP file.
    .DESCRIPTION
    The Merge-ADAuditZip function combines multiple audit report files into a single
    compressed ZIP file. The function takes an array of file paths, a maximum file
    size for the output ZIP file, an output folder for the merged file, and an optional
    switch to open the directory of the merged file after creation.
    .PARAMETER FilePaths
    Specifies an array of file paths to be merged into a single compressed ZIP file.
    .PARAMETER MaxFileSize
    Specifies the maximum file size (in bytes) for the output ZIP file. The default
    value is 24 MB.
    .PARAMETER OutputFolder
    Specifies the output folder for the merged compressed ZIP file. The default folder
    is C:\temp.
    .PARAMETER OpenDirectory
    Specifies an optional switch to open the directory of the merged compressed ZIP
    file after creation.
    .EXAMPLE
    $workstations = Get-ADHostAudit -HostType WindowsWorkstations -Report
    $servers = Get-ADHostAudit -HostType WindowsServers -Report
    $nonWindows = Get-ADHostAudit -HostType "Non-Windows" -Report
    Merge-ADAuditZip -FilePaths $workstations, $servers, $nonWindows
 
    This example combines three audit reports for Windows workstations, Windows servers,
    and non-Windows hosts into a single compressed ZIP file.
    .EXAMPLE
    Merge-ADAuditZip -FilePaths C:\AuditReports\Report1.csv,C:\AuditReports\Report2.csv -MaxFileSize 50MB -OutputFolder C:\MergedReports -OpenDirectory
 
    This example merges two audit reports into a single compressed ZIP file with a maximum file size of 50 MB, an output folder of C:\MergedReports,
    and opens the directory of the merged compressed ZIP file after creation.
    .NOTES
    This function will split the output file into multiple parts if the maximum
    file size is exceeded. If the size exceeds the limit, a new ZIP file will be
    created with an incremental number added to the file name.
 
    This function may or may not work with various types of input.

    <#
    .SYNOPSIS
    Creates a new Microsoft Graph Email app and associated certificate for app-only authentication.
    .DESCRIPTION
    This cmdlet creates a new Microsoft Graph Email app and associated certificate for app-only authentication.
    It requires a 2 to 4 character long prefix ID for the app, files and certs that are created, as well as the
    email address of the sender and the email of the Group the sender is a part of to assign app policy restrictions.
    .PARAMETER Prefix
    The 2 to 4 character long prefix ID of the app, files and certs that are created. Meant to group multiple runs
    so that if run in different environments, they will stack naturally in Azure. Ensure you use the same prefix each
    time if you'd like this behavior.
    .PARAMETER UserId
    The email address of the sender.
    .PARAMETER MailEnabledSendingGroup
    The email of the Group the sender is a member of to assign app policy restrictions.
    For Example: IT-AuditEmailGroup@contoso.com
    You can create the group using the admin center at https://admin.microsoft.com or you can create it
    using the following commands as an example.
        # Import the ExchangeOnlineManagement module
        Import-Module ExchangeOnlineManagement
 
        # Create a new mail-enabled security group
        New-DistributionGroup -Name "My Group" -Members "user1@contoso.com", "user2@contoso.com" -MemberDepartRestriction Closed
    .PARAMETER CertThumbprint
    The thumbprint of the certificate to use. If not specified, a self-signed certificate will be generated.
    .EXAMPLE
    PS C:\> New-GraphEmailApp -Prefix ABC -UserId jdoe@example.com -MailEnabledSendingGroup "Example Mail Group" -CertThumbprint "9B8B40C5F148B710AD5C0E5CC8D0B71B5A30DB0C"
    .INPUTS
    None
    .OUTPUTS
    Returns a pscustomobject containing the AppId, CertThumbprint, TenantID, and CertExpires.
    .NOTES
    This cmdlet requires that the user running the cmdlet have the necessary permissions
    to create the app and connect to Exchange Online. In addition, a mail-enabled security
    group must already exist in Exchange Online for the MailEnabledSendingGroup parameter.
