CloseTheDoor – Port Scanning and Information Tool

closethedoor

CloseTheDoor identifies the listening ports for TCP/UDP over IPv4/v6 and the associated program files. This can help a technician discover security holes and find leaks in a system. It can also find vulnerabilities to help diagnose and prevent future malicious attacks. On a basic level it is a great tool to see all open ports in a visual manner.

It’s amazing how many options are given to you within this program. CloseTheDoor condenses many tasks and command line programs within its simple menu system. This include information that you could find using NET commands, regedit, and services.msc, and well as Googling an unknown process.

    This all cool until you are working on Server 2008 Server Core. With server Core you are back to a blank screen with a blinking prompt. Want speed, low memory utilization, lots of virtulization for lowest TCO know you commands and programs like netsh and dnscmd! The benefit is once you do, you will be the go-to tech. Down side is not all binaries are supported. MS prints a pocket consultant that is good.
