This is different from a port sweep that will only identify open ports, which are assumed to be associated with the default service for that port. The difference is that a port scan and a port sweep will detect that a device has a port open and would assume that the port is associated with the service normally associated with that port. However ...
A port scan or portscan is a process that sends client requests to a range of server port addresses on a host, with the goal of finding an active port; this is not a nefarious process in and of itself. [1] The majority of uses of a port scan are not attacks, but rather simple probes to determine services available on a remote machine.
Despite this port being assigned by IANA, the service is meant to work on SPP (ancestor of IPX/SPX), instead of TCP/IP. [36] 53: Yes: Domain Name System (DNS) [37] [11] 54: Assigned: Xerox Network Systems (XNS) Clearinghouse (Name Server). Despite this port being assigned by IANA, the service is meant to work on SPP (ancestor of IPX/SPX ...
An idle scan is a TCP port scan method for determining what services are open on a target computer [1] without leaving traces pointing back at oneself. This is accomplished by using packet spoofing to impersonate another computer (called a " zombie ") so that the target believes it's being accessed by the zombie.
The Service Location Protocol (SLP, srvloc) is a service discovery protocol that allows computers and other devices to find services in a local area network without prior configuration. SLP has been designed to scale from small, unmanaged networks to large enterprise networks.
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.
Network enumeration is a computing activity in which usernames and info on groups, shares, and services of networked computers are retrieved. It should not be confused with network mapping, which only retrieves information about which servers are connected to a specific network and what operating system runs on them.
ShieldsUP is an online port scanning service created by Steve Gibson of Gibson Research Corporation.The purpose of the utility is to alert the users of any ports that have been opened through their firewalls or through their NAT routers, which can be used by malicious users to take advantage of security vulnerabilities.
