Version detection – Interrogating network services on remote devices to determine application name and version number. [11] Ping Scan – Check host by sending ping requests. TCP/IP stack fingerprinting – Determining the operating system and hardware characteristics of network devices based on observations of network activity of said devices.
ZMap is a free and open-source security scanner that was developed as a faster alternative to Nmap. ZMap was designed for information security research and can be used for both white hat and black hat purposes. The tool is able to discover vulnerabilities and their impact, and detect affected IoT devices.

Network enumeration is the discovery of hosts or devices on a network. Network enumeration tends to use overt discovery protocols such as ICMP and SNMP to gather information. It may also scan various ports on remote hosts for looking for well known services in an attempt to further identify the function of a remote host.
hping is an open-source packet generator and analyzer for the TCP/IP protocol created by Salvatore Sanfilippo (also known as Antirez). It is one of the common tools used for security auditing and testing of firewalls and networks, and was used to exploit the idle scan scanning technique (also invented by the hping author), and now implemented in the Nmap Security Scanner.
Performing a port scan and OS identification (-O option in nmap) on the zombie candidate network rather than just a ping scan helps in selecting a good zombie. As long as verbose mode (-v) is enabled, OS detection will usually determine the IP ID sequence generation method and print a line such as “IP ID Sequence Generation: Incremental”.
Monitoring: This function enables the network management software to monitor the network for problems and to suggest improvements. [2] [3] The software may poll the devices periodically or register itself to receive alerts from network devices. One mechanism for network devices to volunteer information about itself is by sending an SNMP Trap ...
However, an intruder can use banner grabbing in order to find network hosts that are running versions of applications and operating systems with known exploits. Some examples of service ports used for banner grabbing are those used by Hyper Text Transfer Protocol ( HTTP ), File Transfer Protocol ( FTP ), and Simple Mail Transfer Protocol ( SMTP ...
