IP traceback is any method for reliably determining the origin of a packet on the Internet. The IP protocol does not provide for the authentication of the source IP address of an IP packet, enabling the source address to be falsified in a strategy called IP address spoofing , and creating potential internet security and stability problems.
TCP/IP stack fingerprinting is the remote detection of the characteristics of a TCP/IP stack implementation. The combination of parameters may then be used to infer the remote machine's operating system (aka, OS fingerprinting ), or incorporated into a device fingerprint .
On a host with a scanner, the saned daemon runs and handles network requests. On client machines a "net" back end (driver) connects to the remote host to fetch the scanner options, and perform previews and scans. The saned daemon acts as a front end locally, but simply passes requests and data between the network connections and the local scanner.
Nmap (Network Mapper) is a network scanner created by Gordon Lyon (also known by his pseudonym Fyodor Vaskovich). [5] Nmap is used to discover hosts and services on a computer network by sending packets and analyzing the responses.
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.
Image and Scanner Interface Specification (ISIS) is an industry standard interface for image scanning technologies, developed by Pixel Translations in 1990 (which became EMC Corporation's Captiva Software and later acquired by OpenText). [1] ISIS is an open standard for scanner control and a complete image-processing framework.
p0f is a passive TCP/IP stack fingerprinting tool. p0f can attempt to identify the system running on machines that send network traffic to the box it is running on, or to a machine that shares a medium with the machine it is running on. p0f can also assist in analysing other aspects of the remote system.
In information technology, a Christmas tree packet (also known as a kamikaze packet, nastygram, or lamp test segment) is a network message segment or packet with every option enabled for the particular network protocol in use.
