Network Security Audit Script

This PowerShell script is designed to help you audit network security by checking for open ports on local and remote machines. It will help in identifying potential vulnerabilities that could be exploited in a network environment.
Step 1: Define the target host. This script can check specific hosts or your local machine to assess open ports.

$targetHost = "localhost" # Change this to the IP or hostname you wish to target

Step 2: Define a function to check for open ports using the Test-NetConnection cmdlet. This will loop through a range of port numbers.

function Check-OpenPorts {
    param (
        [string]$host,
        [int]$startPort = 1,
        [int]$endPort = 1024
    )
    for ($port = $startPort; $port -le $endPort; $port++) {
        $result = Test-NetConnection -ComputerName $host -Port $port
        if ($result.TcpTestSucceeded) {
            Write-Output "$host port $port is open"
        }
    }
}

Step 3: Execute the function to perform the audit.

Check-OpenPorts -host $targetHost

Step 4: Review the output. The script will display any open ports on the specified host.
