Today I learned more about nMap. It is a network scanner tool that allows you to see what devices are connected to a network, as well as what ports the devices have open. Other variants could be used maliciously to scan the public domain, searching for possible vulnerabilities within networks. There are scans being constantly run over the internet and it is considered an attempted attack to scan somebody else’s network, because this could reveal things that are not your business. However scanning your personal private network is acceptable and this will provide useful information regarding what devices are connected to your own network. I also began working with another program that captures packets being sent over different ports within your system. It is called Wireshark, and I am currently completely mystified by it and I have no idea how it works yet…
