Is there an efficient method to do the same? You will find the answer to these questions lies in Microsoft’s most powerful tool belt, Microsoft PowerShell.
Improper configuration changes to a network—or even just one server on a network—can cause huge issues. They can degrade network performance, shut down key services, and even result in noncompliance with regulatory standards like SOX, PCI, HIPAA and FISMA. And they can compromise network security.
According to the SANS Institute, Port Scanning is one of the most popular techniques attackers use to discover services that they can exploit to break into systems.
