Nmap sends out individual signals to each IP address and waits for a reply. As replies return, Nmap compiles them into a database to keep track of responses, a process that slows down the scanning process. In contrast, ZMap uses cyclic multiplicative groups, which allows ZMap to scan the same space roughly 1,300 times faster than Nmap. [6]
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.
SuperScan is a free connect-based port scanning software designed to detect open TCP and UDP ports on a target computer, determine which services are running on those ports, and run queries such as whois, ping, ICMP traceroute, and Hostname lookups.
A peer-to-peer distribution service that downloads Windows updates and Microsoft Store apps from the local network or Internet peers, and redistributes them to others. Can be configured using either the Settings app or Group Policy. The Settings app can turn it on or off, and specify whether the service operates on the local network only ...
The SAINT scanner, screens every live system on a network for TCP and UDP services. For each service it finds running, it launches a set of probes designed to detect anything that could allow an attacker to gain unauthorized access, create a denial-of-service , or gain sensitive information about the network.
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LANs), personal area networks (PANs), and metropolitan area networks (MANs). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards.
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.
Microsoft Safety Scanner is a free time-limited virus scan utility similar to the Windows Malicious Software Removal Tool. It is used to scan a system for computer viruses and other forms of malware. It was released on 15 April 2011, following the discontinuation of the Windows Live OneCare Safety Scanner. [4]
