Identifying hosts is the first step when enumerating a network, learn how to use nmap to achieve this

Understand how to scan for devices that have an IPv6 address

Use nmap to scan for open TCP (Transmission Control Protocol) ports

Understand the difference between a full connect TCP handshake that completes a 3-way handshake and a SYN scan which does not

As a connectionless protocol, UDP (User Datagram Protocol) takes longer to scan, explore the considerations of UDP scanning in this module

Software “banners” show information such as name and version. Learn how to use scanning tools such as nmap to be able conduct banner grabbing

Turn nmap from a simple port scanner to a fully fledged vulnerability scanner with the use of the nmap scripting engine and the script scan

OS fingerprinting can be used to determine the operating system of a target through by sending specifically crafted packets across the network

Scanning is useless without being able to quickly analyse the information that has been captured. Learn different methods to quickly extract useful data from a scan result

Explore other commonly used nmap flags that may be useful when portscanning

Learn how the quick scanning tool masscan can be used to find open tcp ports

Learn how the quick scanning tool masscan can be used to find open udp ports

Understanding tool output is a key skill, learn how to quickly extract useful information from a masscan output file

When there are no scanning tools available, it is possible to use the inbuilt tools to scan for hosts on a network

Learn how to identify open ports on a target device by using only the inbuilt tools of your operating system
