Security Testing: Nmap Security Scanning

- [Mike] Anything connected to a network that offers services, such as a printer, a router, or a web server, has open ports to accept connection requests. If the correct ports aren't open on a device, it won't function properly. If too many ports are open, the device might be vulnerable to attack. Nmap is one of the most important tools available for cybersecurity professionals, network engineers, and system administrators. Nmap allows you to scan networked devices and determine what ports are open so that you can learn what services they're exposing on the network, verify firewall configurations, or perform testing and troubleshooting.

Once we've covered Nmap's feature set, you'll be ready to run Nmap scans on your own network. And if you don't have systems that you can scan right away, I've built some servers that you can scan to get some hands on experience. Hi, I'm Mike Chapple and I use Nmap almost every day. It's a fantastic tool and I'm looking forward to sharing it with you. All right, let's get rolling.
