Check Active Network Connections

This PowerShell script identifies active network connections on your system, helping you to monitor potentially insecure connections. It’s a valuable tool for assessing your network security posture.
Step 1: Retrieve active TCP connections. This is done using the Get-NetTCPConnection cmdlet, which provides details such as local and remote endpoints.

$activeConnections = Get-NetTCPConnection | Where-Object { $_.State -eq 'Established' }

Step 2: Display the active connections. The script will format the output to show the local address, remote address, and the state of each connection.

$activeConnections | Select-Object LocalAddress, LocalPort, RemoteAddress, RemotePort, State | Format-Table -AutoSize

Step 3: Optionally, save the results to a CSV file for further analysis. This can help keep a record of the active connections for future reference.

$activeConnections | Select-Object LocalAddress, LocalPort, RemoteAddress, RemotePort, State | Export-Csv -Path "ActiveConnections.csv" -NoTypeInformation

By utilizing this script, you can stay informed about the connections established on your network. For more advanced network management and tools, check out ServerEngine at https://serverengine.co for solutions tailored to your needs.
